You might know them as ghost sharks, rat fish, or spook fish. Chimaeras are close cousins of sharks and rays, equipped with distinctive and unusual features in their fins, teeth, and reproductive structures. In today’s oceans, chimaeras are rare and easy to miss, but their extended family includes some of the most diverse and iconic fish of the Paleozoic seas. In this episode, we’ll explore the traits that set chimaeras apart, we’ll take a tour through their ancient relatives, and we’ll investigate what their most famous cousins were doing with their strange spiral rows of teeth.
In the news: Baltic herrings, Cambrian arms race, pterosaur tails, and early dinosaurs.

Most theropod dinosaurs are sleek predators built for speedy movement and efficient hunting. Therizinosaurs are unusual. They’re slow and stocky and, in many ways, more like the famous plant-eating dinosaurs. This episode, we’ll explore the diversity of therizinosaurs, the winding path that paleontologists took to understand them, the many ways they became specialized for a diet of plants, and what was going on with those claws.
In the news: Parasaurolophus crests, Scottish bears, anglerfish evolution, and Clovis diets.

Evolution involves the innovation of new features, but even more reduction of old features. Those reduced features might disappear, develop in a new direction, or just linger as a functionless evidence of deep ancestry. This episode, we explore how we identify vestigial traits, how they help us understand evolutionary history, and the various evolutionary paths vestigial structures can take.
In the news: giant worm lizards, drumstick evolution, dinosaur poop, and pterosaur transitions.

Welcome … to Cute-E!
Every October during Spook-E, we have fun speculatively evolving monsters from myths and stories, but we leave out the cuddlier side of fiction. In Cute-E, we’re choosing kinder creatures and discussing how they – or something like them - could evolve here on Earth, pulling inspiration from real-world species across our planet’s history. This year’s theme is Tiny Monsters.
This episode, we look at a local legend. How might real-world evolution result in elusive and mysterious rabbits with antlers? Our creatures to create this time: Jackalopes.

Some animals are specialists at eating particularly tough foods like shells, seeds, and bones. Adaptations for a durophagous diet come in many forms in almost all major groups of life. This episode, we discuss how so many animals tackle tough foods, what behaviors and anatomy help them to do it, and the importance of durophagy for understanding fossils and the history of Earth ecosystems.
In the news: fossil boas, walking fish, cooked birds, and early arthropods.

Leaves. They’re everywhere. They’re the main photosynthesizing organs of plants, and they’re the main source of green on our green-and-blue planet. Leaves come in a truly dizzying variety of shapes, sizes, and specialized functions, and their early evolution laid the foundation for terrestrial ecosystems as we know them. This episode, Aly joins us yet again to talk about the anatomy and diversity of leaves and the incredible information we can learn from leaves in the fossil record.

Terrestrial animals get around using a variety of gaits: walking, running, galloping, etc. Some of these gaits are particularly bouncy! Hopping comes in many forms in many different groups of animals. This episode, we’ll discuss what makes a particular gait “hoppy,” what functions hopping serves, and what adaptations are found in the best hoppers. Then, we’ll explore what we can tell about hopping in the fossil record.

An animal eating another member of its own species might sound like a rare and abnormal occurrence – and it is often portrayed that way – but cannibalism is actually extremely widespread and common in nature. Some animals are occasional cannibals, while some go so far as to rely on this behavior to fuel proper growth and development. In this episode, we’ll discuss some of the varieties of cannibalism, explore how this behavior has been misunderstood and misconstrued in the past, and investigate some evidence from the fossil record.
In the news: toothless Cretaceous birds, giant river dolphins, Alaska dinosaurs, and Kermit the temnospondyl.

Blending in with the surroundings is an incredibly useful habit. Even without evidence, this fact would be obvious from the sheer variety of organisms that do it and the vast diversity of strategies and adaptations they use. This episode, we look at what camouflage is and how it works in its many forms, and we explore how we can spot camouflage – and what we can learn from it – in the fossil record.

Dragonflies and damselflies are incredible insects. They are arguably the world’s most skilled fliers, arguably the world’s most successful predators, and arguably the best insects (so says David). Not only that, they and their ancient cousins have been abundant and successful aerial predators for over 300 million years. This episode, we discuss what sets these bugs apart from all the rest, we explore what’s known of their evolution from their surprisingly good fossil record, and of course we highlight their most famous extinct cousins: the giant griffenflies.
In the news: croc habitats, tyrannosaur food, elephant trunks, and early mosquitos.

Filter feeding is among the most widespread dietary strategies in the world. From tiny bivalves to massive basking sharks, animals have developed a vast array of convergent strategies for filtering tiny food particles out of the water. This episode, we discuss what it takes to be a filter feeder, why it’s so common, the various methods animals employ to make it happen, and how we try (sometimes successfully) to identify filter feeding in the fossil record.
In the news: Thailand trilobites, mammal aging, bird-like footprints, and whale echolocation.

If things get too hot or too cold, the crucial processes inside the cells and tissues of living organisms stop working properly, and that’s bad. So, organisms expend a lot of time and energy managing their body temperatures. This episode, we break down the familiar concepts of “warm-blooded” and “cold-blooded,” we discuss the many adaptations that animals use to manage the heat, we explore what evidence allows us to interpret thermoregulatory strategies in the fossil record, and we investigate what is known about how these strategies have evolved over time.
In the news: soft robot echinoderms, bird tracks, taste evolution, and dinosaur eggs.

Listen up! The world around us is full of sound, and animals have evolved numerous strategies for receiving and interpreting those sounds. In this episode, we discuss the many varieties of sound-sensing organs and how they’ve evolved repeatedly throughout life history. We’ll also explore some of the other important things that ears can do, including the ever-important task of maintaining our equilibrium.
In the news: carnivorous lampreys, caterpillar legs, early dragonflies, and the sea star body plan.

Welcome … to Cute-E!
Every October during Spook-E, we have fun speculatively evolving monsters from myths and stories, but we leave out the cuddlier side of fiction. In Cute-E, we’re choosing kinder creatures and discussing how they – or something like them - might evolve under the rules of evolution and natural selection, pulling inspiration from organisms of the real world. This year’s theme: Dragons.
This episode, we snuggle up with the sweeter side of dragons. How might natural processes produce intelligent, social, and even amicable draconic beasts? Our creatures to create this time: Friendly Dragons.

These days, we Homo sapiens are the only humans around, but that wasn’t always the case. This episode, we are joined by special guest Dr. Bridget Alex to discuss our most famous extinct cousins, Neanderthals. We explore what makes them similar and dissimilar to us, what evidence we use to study their lives and culture, and how our understanding of them has grown from outdated misrepresentations to the complex and fascinating people we now know them to have been.
In the news: a fossil bat skull, beaver evolution, early pliosaurs, and Ancient Egyptian snakes

Plants are delicious, nutritious, and full of energy, so they’re prime targets for all sorts of herbivores, parasites, and pathogens. But plants aren’t just sitting passively accepting attacks, they use a variety of strategies to defend themselves, from the frustrating to the fatal. This episode, we’re joined by our favorite paleobotanist, Aly Baumgartner, to discuss the many ways plants defend themselves – physically, chemically, and beyond – and the fascinating evolutionary history of plant defenses and their offenders.
In the news: deep-sea fish, Wollemi pines, learning birds, and plant technology.

Earth’s oceans change over time, not just in their size and shape, but also in the very dynamics of their ecosystems. The stage was set for modern ocean ecosystems by an event called the Mesozoic Marine Revolution, a dramatic restructuring of ecology in shallow seas that saw the rise of many forms of active predatory lifestyles. This episode, we discuss the fossil evidence, the major players, and the ongoing and sometimes contentious research into this crucial period.
In the news: early arthropods, early apes, prehistoric ravens, and long-necked marine reptiles.

Eating plants isn’t easy, and yet the habit has evolved many times over the history of life on Earth, and herbivores have become essential components of ecosystems as we know them. This episode, we discuss the adaptations animals use to get around the challenges of plant-eating, as well as the incredible history of the repeated origins of herbivory.
In the news: vampire squids, death by ammonite, early archosaurs, and dinosaur tracks.

For much of their evolutionary history, whales have been divided into two main lineages: baleen whales and toothed whales. The toothed variety are especially diverse today, including sperm whales, belugas, porpoises, and so, so many dolphins (among others). This episode, we explore what makes toothed whales distinct – besides the obvious – and what the whale fossil record tells us about how they came to be among the most successful marine animals in Earth history.
In the news: leaf-eating birds, tiny whales, whale-like reptiles, and giant whales.

Throughout Earth history, tectonic forces have changed the shape of the continents – and the oceans! You might be familiar with the Tethys Sea as an ancient ocean nestled against Pangaea, home to marine reptiles and more, but there’s actually a whole series of ancient bodies of water that bear this name. In this episode, we explore the various iterations of the Tethys, discuss how geologists study them, and examine how these ancient oceans shaped the world as we know it today.
In the news: crocodile conservation, fighting fossils, whale evolution, and bird tracks.

Mammals are famous for their ability to produce milk, a special substance that is essential for providing newborns with the ingredients they need for healthy development. As it turns out, mammals aren’t the only ones. Milk-like substances have evolved in many groups of animals which nourish their developing young. In this episode, we discuss what milk is, what it does, how it seems to have evolved, and the surprisingly long list of times animals have evolved the habit of providing nutritious fluids to feed their offspring.
In the news: Anomalocaris diets, Asian alligators, ancient puberty, and the Cambrian Explosion.

Snakes are surprisingly good at adapting to life in saltwater. Today’s seafaring serpents include a wide diversity of semi-marine species as well as a fascinating assortment of fully oceanic snakes, and this is a tradition that extends well into the past, with numerous radiations of ancient sea snakes. This episode, we explore the repeated evolution of marine lifestyles in snakes, and the array of adaptations that have allowed them to take to the sea. Happy Snake Month!
In the news: dinosaur hands, snake genetics, decapitated reptiles, and cartwheeling snakes.

Most crocodilians today can handle saltwater to some degree, but many of their ancient cousins were much more suited to a life at sea, including some of the most impressive ocean-going reptiles in history. In this episode, we’ll explore the many lineages of marine crocs that have evolved over the last 150 million years, and we’ll dive into the special adaptations that allowed them to take to the seas over and over again. Happy Croc Month!
In the news: a dinosaur transition, tusked dolphins, bird flutes, and crocodile parthenogenesis

When scientists find a new rock formation or fossil assemblage, how do they determine how old it is? The answer lies in the many varied methods of geologic dating. In this episode, we’ll discuss how we can sort the events in Earth history, how we calculate specific ages for ancient materials – including a deep-dive into radiometric dating! – and most importantly, how these many techniques support and complement each other.
In the news: gaze following, polar pterosaurs, pachycephalosaur heads, and giant marsupials.

In our modern world, there are three major groups of mammals: placentals (that’s most of us), marsupials, and the rare and bizarre monotremes. Today’s monotremes – that’s echidnas and platypuses – are famous for their seemingly “un-mammalian” features: they lack external ears, they deliver milk without nipples, and they even lay eggs! This episode, we discuss what makes monotremes unique, the many questions still unanswered about their ancient history, and whether or not they are truly good representatives of early mammal evolution.
In the news: weird mosasaur teeth, Tibetan sabertooths, marsupial growth, and giant pliosaurs.

One of the hallmarks of angiosperms (flowering plants) is the formation of a container to hold their seeds. These containers are fruits, and they come in an astonishing variety of forms and functions, far beyond the typical line up of fruits, nuts, and berries we see at the grocery store. Join us and our favorite paleobotanist Dr. Aly Baumgartner as we explore what fruits are, what fruits do, and how fruits came to be so ubiquitous and important in modern ecosystems.
In the news: big predatory amphibians, exceptional fossil preservation, origins of blinking, and cycad cones.

From roughly 1.8 – 0.8 billion years ago, things on Earth seemingly slowed down. The geologic record shows a conspicuous lack of evidence for major climatic, tectonic, or biological changes, a dramatic contrast to the tumultuous times before and after. In this episode, we explore this so-called “Boring Billion” and discuss what made it so unusual. Along the way, we’ll examine claims that there might have been more going on than we think, that this time might have been a critical step toward the modern state of our planet, and that this billion might not have been so boring after all.
In the news: oldest bats, sauropod skulls, placoderm mouths, and feather-eating beetles.

Check the fingers and toes of your favorite vertebrate animals and you’re likely to find claws or something similar at the ends. These digit-caps come in a variety of shapes – claws, nails, even hooves – for a variety of functions. In this episode, we discuss the close relationship between claw form and function, how we study claws in the fossil record, and the intriguing questions of how claws came to be as we know them today.
In the news: swimming temnospondyls, ants and plants, Troodon eggs, and cooked snails.

You’re probably familiar with frogs and salamanders, but there is a third group of modern amphibians, the strangest of them all: the worm-like caecilians. In this episode, we’ll explore the many bizarre anatomical features of caecilians, from their tentacled faces to their abrupt hind ends. Then we’ll explore the entire caecilian fossil record (it won’t take long) and tackle the much-discussed mystery of how this fascinating lineage of amphibians got started.
In the news: weird marsupial eyes, long dinosaur necks, and kangaroo rats. Also a retraction!

We spend a huge portion of our lives sleeping. For us and other animals, it’s clearly a very important behavior. And yet, despite how familiar and commonplace it is, there’s plenty we still don’t understand about sleep: its origins, evolution, and even how to define it in the first place. In this episode, we explore some of the remarkable variation in animal sleeping habits, we discuss some of the ways we study and understand sleep, and we touch upon the crucial – and much debated – question of what sleep even does for us anyway.
In the news: early monotremes, chunky dunk, Permian pollinators, and parasitic ant mutations.

Once, it was a volcanic crater. Then, it was a lake, perhaps equal parts lush and deadly. Much later, it was a mining site. And finally, today, it is a UNESCO World Heritage Site and one of the most famous and heavily studied fossil sites in the world. In this episode, we discuss the history and formation of the Messel Pit, and we ooh and aah over a small sampling of the many thousands of incredible fossils that have been found there.
In the news: lacewing larvae, folding leaves, dinosaur growth, and ankylosaur sounds.

Giraffes are so famous and familiar to most of us that it can be easy to forget how utterly strange they are. This episode, we explore modern giraffes, their living cousins (okapis!), and their ancient relatives to understand how these monumental mammals came to be how they are. Along the way, we’ll meet a whole variety of wacky-horned fossil species, and we’ll tackle the questions of how and why the giraffe got its long neck.
In the news: dinosaur feet, marine crocs, hunted giant elephants, and bird egg evolution.

Happy Darwin Day!
You’ve seen his artwork. And if you somehow haven’t, you’ve seen lots of art inspired by his artwork. Charles R. Knight might be the most influential paleoartist of all time, inspiring a century’s worth of artists, scientists, and ancient-animal-enthusiasts around the world with his skillful and scientifically-informed works. In this episode, we explore who Knight was, how he became a renowned paleoartist, and his extraordinary role in ushering in the modern world of paleontology.
In the news: Arctic primate-cousins, oldest caecilians, diving bird evolution, and Jehol bird preservation.

Glowing organisms might seem like something out of science fiction, but not only do they exist here on Earth, they are incredibly common. Some species glow when exposed to certain kinds of light, and others produce their very own light in the darkest habitats on the planet. This episode, we explore glowing life: how they do it, what they use it for, and what we can tell about how this remarkable ability came to be.

The Paleozoic Era was home to many strange and fascinating extinct groups, and among the most eye-catching of these were the eurypterids. Colloquially called “sea scorpions,” these carnivorous aquatic arthropods came in many forms for many habitats and are now known from many amazing fossils. In this episode, we discuss what makes eurypterids distinct from similar organisms, what we know about their lifestyles, and the many ways they continue to surprise and confuse us.
In the news: Brazilian crocs, injured cats, breeding ichthyosaurs, and mammal-munching dinos.

It’s a great time of year to talk about conifers! Also their cousins: cycads, ginkgos, and others! Gymnosperms don’t get nearly as much love and attention as their flowering counterparts, the inescapable angiosperms, but they nonetheless have their own fascinating history going all the way back to some of the earliest forests on Earth. This episode, we’re joined once again by our favorite paleobotanist Dr. Aly Baumgartner to discuss what makes gymnosperms unique, what has made them so successful for hundreds of millions of years, and how these incredible plants have changed the world.
In the news: fossil-finding robots, super-old DNA, ankylosaur clubs, and snake sex organs.

Viviparity is the reproductive style where embryos develop inside a parent’s body instead of inside an egg the parent lays. It’s a very familiar habit to us placental mammals, but it’s also an extremely widespread and diverse feature of life. Seriously, it’s ridiculous just how many times viviparity has evolved and just how many different ways species have found to be viviparous. In this episode we’ll answer such questions as: How and why does viviparity evolve? What features vary from one viviparous group to the next? And how do we identify viviparous animals in the fossil record?
In the news: army ants, oldest lizards, beaver families, and swimming dinosaurs.

Built-in body armor is common among reptiles and rare among mammals, but armadillos are the major exception. Equipped with a full set of segmented armor over their heads, backs, and tails, armadillos have been waddling around well-protected for tens of millions of years, and their ancient relatives include some of the most famous and preposterous of extinct mammals. This episode, we discuss the unique features and fascinating history of armadillos, glyptodonts, and their other ancient cousins.
In the news: roots and extinction, new croc-like reptiles, early cooking, and giant turtles.

You might have noticed that over the last few decades, a lot of really exciting and famous fossil discoveries have been coming out of China. If you pay close attention, you might even catch that many of them are coming from the same place: the incredible fossil assemblages of the Jehol Biota. We’ve mentioned Jehol fossils many times on the podcast, but in this episode, we focus on the big picture: where do these fossils come from, why are they so incredibly well-preserved, and what are just some of the fascinating research questions we can answer by examining these amazing fossils?
In the news: bird evolution, dinosaur growth patterns, mammal speciation rates, and glowing scallops.

Look at the various animals on Earth – or rather, look just behind them – and you’ll see a vast variety of tails! Tails and tail-like structures are often simple extensions of the body, and yet they’ve been adapted and modified into many shapes with many functions, and because they’re often so important to an animal’s lifestyle, they can be especially useful for paleontologists trying to understand ancient animals. In this episode, we’ll discuss definitions, diversity, functions, and fossils of tails.
In the news: drought fossils, early fish jaws, early fish fins, and paleontology video games.

Welcome ... to Spookulative Evolution.
October is here, and that means it’s time for Spook-E! Each episode throughout this month, we’re choosing a monster and discussing how it – or something like it – might evolve under the rules of evolution and natural selection, pulling inspiration from organisms of the real world. This year’s theme: monsters of Dungeons and Dragons.
This episode, we delve into a paranoia-inducing scourge of dungeons. What hypothetical natural scenario might cultivate a shape-shifting ambush hunter that disguises itself as inanimate objects? Our creatures to create this time: Mimics.

Welcome ... to Spookulative Evolution.
October is here, and that means it’s time for Spook-E! Each episode throughout this month, we’re choosing a monster and discussing how it – or something like it – might evolve under the rules of evolution and natural selection, pulling inspiration from organisms of the real world. This year’s theme: monsters of Dungeons and Dragons.
This episode, we gaze upon something truly alien. Can we formulate an evolutionary path to produce a malicious floating orb creature that stares at the world through many eyes? Our creatures to create this time: Beholders.

Stegosaurus is one of the all-time most famous and recognizable dinosaurs, but it wasn’t alone! Its whole extended family, the stegosaurs, were medium- to large-sized herbivorous dinosaurs sporting an array of plates and spikes. This episode, we discuss the diversity and deep history of stegosaurs, what we know of their lifestyles, and of course the big questions: just what were they doing with that ridiculous armor?
In the news: Moon impacts, bird brains, Jurassic vomit, and super-old algae.

In our modern world, ants are so ubiquitous that it’s difficult to image our planet without them, so successful that they shape the environments around them despite their tiny size, and so diverse that we couldn’t possibly discuss even a small fraction of their diversity in this one podcast episode. We’ll touch on some of what makes ants unique, list a few of our favorite examples of modern ant lifestyles, and dive into what is known about their ancient history and evolution. Get ready for fire ants, bullet ants, dinosaur ants, hell ants, and more.
In the news: mysterious maybe-molluscs, giant otters, tuatara cousins, and fossil fish organs.

Powered flight is hard, and evolution has only produced it a few times. Gliding, however, is much easier and much more common. In fact, there is an astonishing diversity of gliding organisms to be found in our modern world as well as in the fossil record, with an incredible variety in the adaptations they use to sail through the sky. This episode, we’ll explore what it takes to glide and what patterns we see in gliding evolution, and we’ll also geek out about all the amazing sizes, shapes, and strategies of gliders.
In the news: coral mutations, African dinosaurs, croc brains, and ancient amputation.

For many years, scientists pondered the question: how and why do offspring inherit traits from their parents? And key to the answer to that question is another question: what determines an organism’s traits in the first place? The pursuit of these answers ultimately led to the modern field of genetics, which itself is crucial to the study of evolution. This episode, we address just a few key points on this vast topic, with a focus on how our understanding of genetics allows us to interpret the history of evolution on our planet.
In the news: early fruit-eating, giant Australian birds, beaver evolution, and human speech.

Every period of geologic time is distinguished by its own environmental and ecological features, and every boundary between time periods is characterized by change. The boundary between the Jurassic Period and the Cretaceous Period is mostly marked by mystery. Was there a mass extinction? Were there catastrophic changes? Where even is the boundary exactly? In this episode, we’ll discuss the answers – or lack thereof – to these questions and more as we explore this surprisingly enigmatic time in Earth history.
In the news: croc conservation, diving whales, aquatic mammal-cousins, and sauropod feet.

We live in a solar-powered world. Photosynthesis is the process by which some organisms (notably plants and cyanobacteria) harness the energy of sunlight to power their own metabolism, in the process creating the sugars (food) which provide a source of energy for all sorts of other organisms, not to mention releasing oxygen as well. Photosynthesis is the reason our planet is the way it is, from the diversity of life to the composition of the atmosphere. In this episode, we discuss the diversity of photosynthesis and photosynthesizers, what we know about the evolutionary history of the process, and how it has profoundly changed the world.
In the news: freshwater plesiosaurs, endothermy evolution, whale shark diets, and bone-crushing dogs.

The history of evolution is full of species of unusual size, big and small. But the factors that lead to evolutionary miniaturization or embiggening can be quite varied and are not all fully agreed-upon by scientists. This episode, we discuss what it means for life to evolve huge or tiny, what trends researchers have identified in body size evolution, and which of those trends actually holds up to further scrutiny.
In the news: krait venom, a frozen pup, parental water bugs, and giant storks.

Monitor lizards are charismatic, surprisingly diverse, full of surprising biological features, and on top of all that, they include the largest terrestrial lizards in history. Also, they’re closely related to snakes (it is Snake Month, after all). That’s a cool group of lizards! In this episode, we discuss what makes these lizards so unique and fascinating, and we dive into their long but often mysterious fossil record to address some major questions about monitor evolution.

Take a walk along the waterways of the Late Triassic, and you could easily think it was a world full of crocodiles! But in fact, those are not crocs, but phytosaurs, a group of predatory reptiles that represent not only one of the oldest groups of carnivorous reptiles to achieve a near-global distribution, but also one of evolution's most famous cases of convergent evolution. So, what features did phytosaurs share with crocs? Where did they differ? And just how croc-like were their lifestyles? Listen in and find out!
In the news: dinosaur belly buttons, tiny frogs, snake venom, and giant dwarf crocs.

Happy Croc Month!
In this special episode, we talk croc conservation and geek out about crocs with special guest Dr. Marisa Tellez of the Crocodilian Research Coalition. We learn about what it’s like to study crocs in the wild, we discuss the importance of public education, and we hear some of Marisa’s amazing croc tales!

Perhaps you’ve heard of Pangaea, the supercontinent that existed when our modern continents were puzzle-pieced together. But have you heard of Rodinia? Or Columbia? Scientists have only come to realize in the last few decades that supercontinents are a recurring feature of our planet. This episode, we discuss what counts as a supercontinent, what evidence they leave behind, and the various ways they impact just about every other feature of our planet as they continuously come together and break apart.
In the news: croc resilience, American cheetahs, dome-headed giraffoids, and traveling termites.

Who doesn’t like a flashy bit of headgear? A wide variety of cranial ornamentation is found on a wide variety of animals: sharp horns, branching antlers, bumpy knobs, and more. In this episode, we break down what technically counts as a “horn” (you’ll be unsurprised to learn there isn’t a simple answer!), the vast diversity of animal headgear today and in the fossil record, and the various ways animals have found to use these remarkable structures.
In the news: sabertoothed faces, head origins, dinosaur climates, and ancient false gharials.

Scavenging isn’t easy. There’s a reason most scavengers are only part-time carrion-eaters. But vultures are exquisitely adapted for a dedicated lifestyle of finding and feasting on carcasses, and as a result, they’ve made themselves invaluable members of ecosystems all over the globe. In this episode, we explore vulture evolution, their ancient history, and the adaptations that make them the world’s most famous scavengers.
In the news: insect wings, trilobite mating, a “small” sauropod, and post-Cretaceous plants.

It's an easy mistake to think of the Moon as a simple accessory to our planet, but the Earth and Moon are a close-knit pair, and the Moon influences everything from our tides to our magnetic fields to the brightness of our nights. All life on Earth has evolved in the presence of the Moon, and so life on Earth can't be fully understood without considering our cosmic companion. In this episode, we discuss how the Moon influences life past and present, and what we know about the deep history of the Earth-Moon relationship.
In the news: pterosaur colors, a glowing spider, deformed pollen, and a long-toed tetrapod.

We talk about fossils a lot on this podcast – every episode, in fact – but we rarely take the time to discuss how fossils get the way they are. This is a crucial subject, because the fossilization process is a filter, and nothing comes through the filter unaltered, and many things don’t come through at all. In this episode, we talk about how fossils typically form, how we study this process, and why it’s so important for paleontologists to understand fossilization.
In the news: giant croc tracks, injured dino footprints, evolution in cities, and ancient snakey-ness.

Seahorses are very strange fish, with their upright posture, tube-like mouths, and various other unusual features. Along with their cousins in the family Syngnathidae, seahorses have been the subject of much research into how they came about their bizarre body plans and lifestyles. In this episode, we discuss a bit of what we know of how seahorses (and their relatives) do what they do, and how they came to do it.
In the news: trilobite predators, early jaws, de-extinction troubles, and spinosaur bone density.

Every plant starts somewhere, and often that somewhere is inside a seed. Seeds are among the most diverse and important evolutionary innovations of plants, allowing species to survive, thrive, and travel between generations in extraordinary ways. This episode, Aly joins us to discuss how seeds do what they do, how seeds have evolved over time, and how seeds are invaluable resources for paleontologists seeking to understand plants of the past.
In the news: early octopus-cousins, early tuatara cousins, evolution of walking, and how sauropods moved.

Blood is nutritious, easy to digest, and not hard to come by, so it’s unsurprising – if a bit unsettling – that thousands of species have evolved a taste for the stuff. From birds to bats to bugs, the diversity of sanguivores includes a wide variety of body plans, feeding strategies, and unique evolutionary histories, all converging upon a similar set of behaviors and features honed for a diet of blood. Be aware, this episode is, at times, kinda gross.
In the news: a new spinosaur, a new pterosaur, a new abelisaur, and a new euphorbia.

None of us are alone. Like, in the literal, biological sense. Symbiotic relationships – close interactions between unrelated organisms – are a defining feature of life on Earth. Each of our bodies has its own share of parasites, hitchhikers, and tiny helpers, and some of the most prominent ecosystems on Earth function only by virtue of the symbiotic relationships at their foundations. In this episode, we touch on the incredible diversity and impact of symbiosis, and how the deep history of these relationships has created the world we know today.
In the news: sick sauropods, puking pterosaurs, jumping genes in snakes, and dino-eating crocs.

Volcanoes are fascinating, devastating, and fundamental to Earth systems. Volcanic eruptions can transform ecosystems, landscapes, and even the atmosphere, and at their most extreme, the effects of volcanism can be global and long-lasting. In this overstuffed episode, we discuss the many forms and features of volcanic activity, and we take a look at the complex and dramatic interaction between volcanoes and life on Earth.
In the news: ankylosaur brains, an Australian rainforest, donkey hybrids, and the Tonga volcanic eruption.

With every breath you take, you’re collecting information about your surroundings. We humans are actually pretty skilled smellers, as these things go, but olfactory abilities vary widely across the animal kingdom (and beyond). In this episode, we discuss how smelling works, what smelling is good for, and how scientists explore the evolutionary history of smell.
In the news: giant ichthyosaurs, giant millipedes, long-tongued birds, and oviraptorid embryos.

Today, rhinos are famous for their large size and impressive horns (and their distressing conservation status, sadly), but modern rhinos are only a small sample of what rhinos have been over time. Thanks to a surprisingly good rhino fossil record, we have a pretty good picture of how these animals got started and of the surprising forms they’ve taken since, from horse-like runners to hippo-shaped waders to gargantuan behemoths. This episode, we discuss rhinos as we know them, rhinos when they were weird, and a few rhino-y things that aren’t rhinos at all.
In the news: ancient croc hunting, dinosaur colors, shrinking orangutans, and ammonite soft tissue.

Far below the ocean surface is a vast environment of cold, darkness, very scarce food, and surprisingly diverse life. Deep sea life is quite mysterious, in part because of their unusual adaptations for surviving in such tough habitats, and also because it’s very difficult to study organisms of the deep, modern or fossil. In this episode, we discuss what is known about the adaptations, evolutionary history, and diversity of life in the deep sea.
In the news: blade-tailed ankylosaurs, ostrich-like dinosaurs, shrimps in clams, and carnivorous ichthyosaurs.

Evolution loves to plagiarize. You might be surprised at just how useful it can be for an organism to copy the signals, sights, sounds, and smells of others. Mimicry is all about making use of miscommunication. In this episode we’ll discuss the astounding diversity of modern mimics, the rare examples of fossil mimics, and the complex and confusing evolution patterns of mimicry.
In the news: Cambrian bryozoans, early tusks, hermit worms, and parthenogenetic condors.

Welcome ... to Spookulative Evolution.
October is here, and that means it’s time for Spook-E! Each episode throughout this month, we’re choosing a famous monster and discussing how it – or something like it – might evolve under the rules of evolution and natural selection, pulling inspiration from organisms of the real world. This year’s theme: monster plants.
This episode, we face a more modern monster, star of page and screen. Can we invoke natural processes to develop a plant that haunts humans and strikes with a deadly lash? Our creatures to create this time: triffids.

An Earth covered in ice might sound far-fetched, but there’s reason to think it has actually happened in the past – more than once. In this episode, we examine the Snowball Earth hypothesis and the geologic evidence and climate models that back it up, as well as some of the major lingering questions: Just how snowy is the snowball? How could this start? How could it end? And how did life fare on a frozen planet?
In the news: ancient tardigrades, meat-eating sloths, shark communities, and relict mangroves.

The Earth is in motion beneath our feet. The shifting and grinding of the tectonic plates is responsible for the shape of our planet’s surface and – directly or indirectly – nearly all the activity that happens upon it. Plate tectonics has a deep and fascinating history, both as a force that has shaped the Earth for billions of years and as a surprisingly recent foundational scientific theory.
In the news: shark teeth, Cambrian predators, Carnotaurus skin, and teratorns.

Nearly all animals have some form of nervous system, and this system is often monitored and regulated by a brain. We humans are particularly proud of our enormous brains, but these organs come in all shapes and sizes across the animal kingdom, past and present. In this episode, we discuss brain diversity, the sometimes roundabout ways we explore brains in the fossil record, and what we’ve come to learn about the evolution of brains.
In the news: turtle embryo, frog-legged leaf beetle, early lizard cousin, and tyrannosaur brains.

Ever since T. rex was first identified in 1905, tyrannosaurs have been among the most famous and well-studied dinosaurs of all time. Research, especially in the last few decades, has revealed incredible details of tyrannosaur evolution, lifestyles, and development. This episode, we take a tour through tyrannosaur history, envision what these predators were like in life, and touch on some of the most prominent tyrannosaur controversies, including their notorious popularity.
In the news: venom evolution, mammoth roaming, Jurassic land-croc, and climate change.

India is a landmass with an incredible history. Over the past half-billion years, it has spent time with the southern continents, time as an island-on-the-move, and time with the northern continents. Its fossil record is a combination of southern life, northern life, and uniquely Indian life, and its geologic history is not only the story of a traveling subcontinent, but also the origin story of one of Earth’s most impressive mountain ranges.
In the news: baby pterosaurs, vampire bats, early sponges, and snake-y ancient reptiles.

As organisms live, grow, and move in their environments, they leave all sorts of traces in their surroundings, and these can become fossilized just like body parts can. Trace fossils (ichnofossils) can include evidence of burrowing, walking, feeding, and more. Individual trace fossils are great for understanding the behaviors of ancient organisms, and communities of trace fossils can help us track major changes in ecosystems through time.
In the news: damaged cave bear, shrinking dinosaurs, koala lemurs, and megaripples.

What exactly is a “crab” anyway? One answer is that they are among the most diverse and successful living arthropods. Another answer: they are many different groups of crustaceans that have converged on a crabby body plan. In this episode, we discuss the diversity and evolution of “true crabs,” the incredible phenomenon of carcinization that keeps creating crabs, and what it really means to be a “crab.”
In the news: poop beetles, Arctic dinosaurs, Dragon Man, and an ancient shark attack.

The history of evolution has seen many land animals move to the sea, but few have done it with such success and specialization as ichthyosaurs. These Mesozoic marine reptiles were the first group of tetrapods to truly dominate the marine realm, and they evolved some of the most extreme adaptations – and largest bodies – of any ocean-dwelling tetrapods. This episode, we discuss how they got started, what they did, where they went, and why they’re so incredibly famous.
In the news: giant crocs, giant rhinos, young tyrannosaurs, and dwarf elephants.

All over the Earth, there are biological communities that differ depending on the local climate and landscape. These are biomes, and biologists love to map them to unravel patterns of ecosystem distribution. But biomes also change over time as climates and landscapes shift. In this episode, our favorite paleobotanist, Dr. Aly Baumgartner, joins us to discuss how we identify biomes in the past and present, how they’ve changed over time, and what it means for a new biome to arise … or for an old one to go extinct.
In the news: whale diets, moa poop, shark extinction, and flower seeds.

Far to the north and far to the south, conditions on Earth get weird. Cold climates and periods of perpetual night or day create some of the most unique habitats on the planet. In this episode, we look at what makes the polar regions so strange, how they’ve changed over time, what it takes for life to survive there, and what fossils tell us about what lived there in the past.
In the news: gut microbiomes, chewed Neanderthals, ancient symbiosis, and very old turtles.

The geologic record of Earth is an archive of data on the causes and effects of changing climates. As climate changes, it impacts everything from plants and animals to rocks and rivers. The study of ancient climates is paleoclimatology, and it’s important not only for our understanding of climate in the past, but also for teasing out what’s happening with our climate today and what we can expect for the future.
In the news: tyrannosaur group, a chomped squid, horned crocs, and night dinosaurs.

There isn’t much on Earth quite like an ant colony or a beehive. Lots of animals are social, but relatively few are eusocial. It’s a bizarre lifestyle, living in large multi-generational colonies with lots of members who don’t reproduce but instead dedicate their lives to protecting and nourishing the offspring of the few reproducers. In this episode, we discuss the many questions surrounding this phenomenon, including how many times this trait has evolved, why it’s apparently so beneficial, and exactly how natural selection could even produce such a strange lifestyle.
In the news: venom evolution, pointy things, early rainforests, and bone origins.

Penguins aren’t the only flightless birds, and they aren’t the only diving birds, but they sure are good at doing both! In this episode, we discuss modern penguins’ unique suite of adaptations that allow them to spend so much of their lives in the water, and then we address some of the most pressing questions about their past: How did they get their start? What drove their evolution? And why were some of them so disconcertingly large?
In the news: giant coelacanths, really old DNA, fossil vampire squid, and dinosaur ecology.

Taking teeth to the extreme! Tusks have evolved numerous times, particularly in mammals, and they’ve come in a striking array of shapes and sizes for a variety of uses. From the monstrously huge ivory tusks of mammoths to the modest yet effective tusks of fanged deer to the bizarre and perplexing tusks of babirusas and narwhals, in this episode we discuss trends, drivers, and mysteries in the evolution of tusks.
In the news: razor-toothed mosasaurs, walk the dinosaur, sidewinder skin, and really old giant sloths.

Happy Darwin Day!
Baron Franz Nopcsa was a paleontologist around the start of the 20th Century, remembered today for his innovative fossil research, his (in)famous personality, and his fantastic adventures across Eastern Europe. In this episode, we’ll discuss how this aristocrat became a paleontologist and how he contributed to our modern understanding of dinosaurs, and we’ll share some of the incredible and bizarre stories that surround him.
In the news: Parasaurolophus crests, sand striker burrows, dogs in Siberia, and life on Pinatubo.

A new tradition begins! Get ready for more plants with our friend Dr. Aly Baumgartner!
Most plants are content to sit still and take in sunlight and soil nutrients, but when conditions are tough, some plants get hungry! The habit of devouring small animals has evolved in plants several times. In this episode, we discuss what counts as carnivory in plants, why they do it, the various methods plants use to murder their meals, and what little we know about the evolutionary history of this behavior.

Seals, sea lions, and walruses (oh my!) are widespread, successful, and invariably charming. In this episode, we take a look at how they’re adapted for their aquatic lifestyles and how they might have gotten that way. We’ll explore some of the unanswered questions about their origins and evolution, and we’ll take a tour through their diverse but spotty fossil record.

The PETM has been called the largest natural climate change event of the Cenozoic Era. It marks the transition from the ecosystems of the Paleocene to the more familiar world of the Eocene and is thus an important step in making the world the way we know it today. But maybe most importantly, it is a dramatic case study in what happens when a huge amount of Carbon injected into the atmosphere triggers rapid warming of global climate … you know, in case anyone needs to know about that.
In the news: pterosaur cousins, oldest pythons, burrowed dinosaurs, and hibernating hominins.

The word parasite doesn’t typically invoke a lot of happy thoughts for us humans, but as far as life on Earth is concerned, parasitism is a path to success. As we discuss in this episode, an incredible diversity of organisms, past and present, have developed an equally incredible diversity of strategies for stealing, siphoning, and exploiting resources from other organisms.
In the news: surprise bird beak, alligator tails, flightless birds, and chemical re-assessment.

Is there a group of dinosaurs more iconic than sauropods? Famous for their ridiculously long necks, their global success, their astounding diversity, and of course for their unparalleled size, sauropods have fascinated and puzzled people for centuries. In this episode, we’ll explore what makes sauropods and their ancestors special, and we’ll talk a bit about how they functioned at truly colossal scales.
In the news: strange-jawed sharks, ancient walruses, dinosaur demise, and the oldest blindsnakes.

One hundred episodes is kind of a big deal, so we figured we’d pick a big deal kind of topic, and it doesn’t get much bigger than this.
As far as we can tell, all life on Earth is descended from a common ancestry – at some point, at least once, life originated on Earth. But when, where, and how? These are open questions that have been subject to lots of scientific and philosophical discussions and experiments. In this episode, we’ll touch on some of the biggest questions: What even is life? How old is life on Earth? What steps led to the first living things? Is Earth the only place this has happened?
In the news: dino bone disease, amphibian chameleons, ancient social mammals, and pterosaur diets.

Insects must be among the most impressive animals in Earth history. For hundreds of millions of years, they have been some of the most significant animals on land in terms of their abundance, diversity, and ecological impact. Their deep story is marked by evolutionary innovations that weren’t just major events for insects, but major events for the entire planet. This episode, we barely scratch the surface of the insect story.
In the news: a new pterosaur, big Antarctic birds, gliding dinosaurs, and a dinosaur cloaca.

Welcome ... to Spookulative Evolution.
It’s October once again and time for Spook-E! Each episode throughout this month, we’re choosing a monster and discussing how it – or something like – might evolve biologically, pulling inspiration from critters of the real world. This month’s theme: sea monsters.
This episode, we turn our attention to the creatures whose enticing songs sound over the sea. How can we naturally evolve a group of humanoid(ish) island-dwellers whose voices lure in victims? Our creatures to create this time: the Sirens.

When we study life, past or present, we talk a lot about species, their evolution, their diversity, their extinction, and more. But we don’t often slow down to discuss what we really mean by that. What is a species? How and where do new species arise? It turns out this topic is much more complicated – and controversial! – than it may seem. In this episode, we’ll touch on the basics and discuss why scientists get so worked up about species and speciation.
In the news: a glass-ified brain, a Cretaceous croc, a long walk, and a sensitive dinosaur.

Okay, that’s not a great title. More accurately, we’re discussing toxins, the substances that organisms produce for chemical defense or attack against each other. Toxins are found in practically all living things, they function as part of immune systems, poisonous defenses, and predatory venom, and they have all sorts of amazing effects from discomfort to death. In this episode, we’ll touch on who has them, what they do, and what we know about the long, complex evolutionary history of venom and biological poison.
In the news: Spinosaurus teeth, an overlooked extinction, bird beaks, and Neanderthal DNA.

Marsupials are like alternate-reality mammals. Everything about them, from their skeletons to their reproductive strategies, is just a bit strange – from the perspective of us placental mammals, that is! But you can’t argue with results, and marsupials include some of the most fascinating mammals of the past and present. In this episode, we track the long evolutionary journey that gave the modern world its kangaroos, koalas, possums, opossums, and more.
In the news: air-breathing sea scorpions, fish bone evolution, mastodon migrations, and burrowing dinosaurs.

This episode marks the end of our extinction series, but on the bright side, Aly’s here!
Most of the extinction events we discuss are very animal-focused, but the end of the Carboniferous Period featured one of history’s worst plant extinctions. This event wiped out the famous ecosystems of the Carboniferous, reshuffled ecosystems, and ushered in a more familiar world of plants. In this episode, as usual, we discuss what happened, why, and how it impacted the world.
In the news: a croc-bitten sloth, a dinosaur embryo, dinosaur dimorphism, and ancient hibernation.

Dogs are among the most diverse and successful mammalian predators on the planet, from widespread wild predators like wolves to the most iconic domestic species of all time in our own homes. This episode, we look at what makes dogs unique, where they got their start, what their fossil history has looked like, and finally how one species ended up being among the most widespread species on Earth.
In the news: hell ants, weird reptiles, dinosaur cancer, and “super-crocs”

Everybody starts somewhere, and most animals start inside an egg! Eggs are about as old and as varied as animal life itself, and when they show up in the fossil record, they can be very telling. In this episode we discuss what goes inside an egg, what makes them so special and useful, and what we can learn from their patchy fossil record.
In the news: early archosaurs, more on Dilophosaurus, Microraptor feathers, and a large dolphin.

Roughly nine out of ten living amphibian species are frogs. They’re incredibly diverse and successful, and they have been since the Jurassic Period. But the origins of frogs and their fellow modern amphibians is shrouded in mystery. In this episode, we discuss what makes frogs special, what their fossil record looks like, and what paleontologists know and don’t know about the earliest evolution of modern amphibians.
In the news: colorful insects, salamander evolution, saber-toothed marsupials, and venomous caecilians?

"Living fossils" aren't really a thing, not the way they're typically talked about anyway, and the term can be a source of debate among scientists and science communicators. In this episode, we talk about how this term is used and why some scientists defend it while others (including us!) aren't fans.

In the Canadian Rockies of British Columbia sits one of the most important, well-studied, and scientifically influential fossil sites in the world. The Burgess Shale not only provides us a glimpse into the tail end of the Cambrian Explosion, and not only yields tens of thousands of fossil specimens, but also includes some of the most exceptional fossil preservation of any fossil locality anywhere. This episode, we’ll dive into how it got that way, and what it has to tell us about some of Earth's earliest animal communities.
In the news: baby sharks, hungry dinosaurs, a pregnant ichthyosaur, and one dino’s last meal.

Start exploring vertebrate evolution and paleontology, and it won’t be long before you end up on the subject of teeth. These handy structures are enormously significant not only for the history of life, but in the study of it as well. In this episode we discuss what makes a tooth a tooth, how teeth came to be, and we muse at length over the incredible diversity and scientific usefulness of teeth.
In the news: dinosaur walking, gharial males and females, hurricane-induced evolution, and humans in Australia.

We’ve discussed mass extinctions quite a bit on this podcast, and indeed we’ve devoted episode to four out of the famous “Big Five” that shaped life on Earth. This episode, we’re completing the set with the Ordovician mass extinction, the earliest of the five. As usual, we’ll explore what happened, who it happened to, why it happened, and how it left its mark on life on Earth.
In the news: ocean crocs, early archosaurs, ancient humans, and post-extinction lakes.

Life ain’t always easy. Injury and disease are a persistent threat for life of all sorts, and that’s been true for as long as there has been life. Fortunately for us, these threats can leave evidence in fossils, teaching us about the lives, struggles, and sometimes deaths of ancient organisms. The study of this evidence is called paleopathology, and in this episode, our friend Laura will explain the ins and outs of the field and share with us some of her favorite examples.
In the news: ancient hands, old snakes, the earliest animals, and a new dinosaur.

In 1938, a fishing crew pulled up a fish that everyone thought had been extinct for 70 million years. Since then, coelacanths have become famous not just for their strangely incomplete fossil record, but also for their unique anatomy, their reclusive lifestyle, and their close relationship to land vertebrates. From fossils to genetics, this episode is all about what we know – and what we’re missing – of the story of coelacanths.
In the news: an old weasel, fish through time, daily bivalve growth, and cave cockroaches.

Few fossil animals are as popular with the public, as abundant in the fossil record, or as important to the study of past life on Earth as trilobites. These ocean-dwelling arthropods came in an amazing variety of shapes, sizes, and lifestyles, with many thousands of identified species, and they persisted on our planet for more than 270 million years. And best of all, they left behind an incredible fossil record giving us insights into their evolution, life history, and ultimate extinction.
In the news: evolution of gliders, a weird worm, tiny marsupial lions, and dino DNA?

Metamorphosis is the process that turns a caterpillar to a butterfly, a fry to a fish, and a tadpole to a frog. Animals have been metamorphosing for over 500 million years, from early crustaceans to the many fish, amphibians, and arthropods that do it today. Larvae, pupae, and adults are known in the fossil record, but the evolutionary history of this incredible life strategy is still mysterious.
In the news: a new tyrannosaur, early chameleons, giant turtles, and dinosaur temperatures.

Happy Darwin Day!
This time around, we’re talking about Mary Anning! She was one of the earliest modern paleontologists, she helped lay the groundwork for our modern methods of uncovering and understanding fossils, and she was famously underappreciated in her time. We’re joined in our discussion by our friend Brittney Stoneburg from the Western Science Center!

The first pterosaur to be scientifically identified was Pterodactylus, more than 200 years ago. Since then, scientists have grappled with understanding these bizarre and fantastic animals, aided by inspired science and incredible discoveries. In this episode, we’ll discuss what we know – and what we don’t know – about how these animals evolved, survived, and ruled the skies in the Age of Reptiles.

Hand a kitchen appliance to a child and they’re likely to find a whole new way to use it. This happens in evolution, too – traits adapted for one purpose turn out to be beneficial for a whole other reason, and so the trajectory of natural selection changes. The term for this is exaptation, but it’s a complicated concept, and not everyone even likes using the word. Let’s discuss what this word means, why it exists, and what some people find wrong with it.
In the news: the oldest forest, an ancient parent, young T. rex, and fossil lungfish.

Happy New Year!
As we transition into a new decade, this episode is about one of the most important and incredible transitions in the evolutionary history of life. In the Late Devonian, one particular group of bony fish spent many millions of years experimenting with new forms of fins, skulls, and lifestyles, ultimately giving rise to the first land-dwelling vertebrates and setting the stage for 300 million years of continental dominance.
In the news: the earliest penguins, ancient whale swimming, dinosaur lice, and really old brains.

The evolution of horses is a classic story, first because it is a beautiful example of evolution in the fossil record, and second because of how our scientific perspective of this story has shifted over the years. From the tiny forest-dwellers of the Eocene, barely recognizable as horse-relatives, to the mighty domesticated animals we know today, we’ll unpack what we know – and what we thought we knew – about horse evolution.
In the news: dinosaur teeth, alligator tools, ancient embryos, and dinosaur heads.

Welcome to the world of Pokémon Paleontology! In this digression – by popular demand – we explore how the fictional world of Pokémon draws inspiration from real world science, particularly in regard to fossils and evolution. We’ll name our favorite fossil Pokémon, discuss Pokémon evolution, and point out where the Poké-science gets wonky.
What’s your favorite bit of Pokémon science?

Time for another extinction! This time, we’re discussing what might be the most ancient, most mysterious, and most catastrophic mass extinction event of all time. The Great Oxidation Event marks the turning point that set our atmosphere on course to its current oxygen-rich state and made the Earth hospitable for life as we know it … at the expense of all the life that came before.
In the news: the largest ape, early pollinators, early birds, and early snakes.

Aly's back for more plants!
As our friend Aly is fond of pointing out, plants aren't just the colorful background of Earth history, they're dynamic and influential drivers of environmental change. And few plant innovations are more famous or important than the familiar form of a tree. For hundreds of millions of years, trees have formed the basis of many of our planet's most widespread and diverse ecosystems. In this episode, Aly takes us on a tour of tree history!
In the news: more dinosaur air conditioning, trilobite lines, moth hearing, and 1,000 plant trascriptomes.

Welcome ... to Spookulative Evolution.
It’s October, and we’re back with more Spook-E! Each week this month, we’re choosing a creepy creature and discussing how it – or something like – might evolve biologically, pulling inspiration from critters of the real world. This month’s theme: monsters of Greek mythology.
In this final episode of this season, we take on the task of evolving the most famous of mythical hybrids. Can our evolutionary processes combine the traits of reptiles, mammals, and more? Our creatures to evolve this time: Chimeras.

The oceans of the Mesozoic were home to a lot of fascinating sea predators, but perhaps none weirder than the plesiosaurs. Four giant flippers, tiny tails, and heads that ranged from enormous death traps to tiny noggins atop ridiculously long necks; there’s truly nothing like them in the world today, which makes them quite the prehistoric puzzle. In this episode, we’ll discuss what we know about them and what questions remain unanswered.
In the news: sauropod beaks, croc snouts, the last mammoths, and mold pigs!

During the Cretaceous Period, North America flooded. The entire middle section of the continent was submerged, creating an inland sea that stretched from the Arctic to the Gulf of Mexico and hosted a unique and fascinating underwater ecosystem. Not only that, but it split west from east, creating two distinct "subcontinents." In this episode, we explore how this sea came to be, what lived within it, and what effect it had on land ecosystems of the time and the fossil record they left behind.
In the news: more crocs, the oldest fossils, a history of CO2, and unexpected fossil sex.

With all the incredible diversity of life, it’s fascinating how often evolution repeats itself. The fossil record and the modern world are full of signs of this pattern of convergent evolution – similar pressures drive organisms to similar features and lifestyles. In this episode, we’ll talk about what exactly convergent evolution entails, share some of our favorite examples, and talk about how things can get a bit confusing.
Did we mention your favorite example of convergent evolution?
In the news: rhino DNA, baby sea turtles, sea snake breathing, and dinosaur temperatures.

It’s dinosaur time again! This episode, the spotlight is on the “living tanks” of the Mesozoic, the armored ankylosaurs. These impressive creatures were covered head to tail in dazzling armor that puts most other fortified animals to shame. We’ll discuss what exactly they may have been doing with that armor and how they fit into dinosaur-filled ecosystems. Oh, and we’ll talk about those tail clubs, too.
In the news: shark-bitten whales, an early hominin skull, “killer” claws, and pterosaur poop.

If you’re reading this, there’s a very good chance you’re using one of the most incredible tools in the animal toolkit: the eye! In this episode, we discuss what’s known – and what’s suspected – about the incredible evolutionary history of the eye. How many types of eyes are there? What is an eye, anyway? Just how difficult is it to evolve something so intricate and complex? All this and more!
In the news: a giant parrot, a giant penguin, ancient RNA, and crinoid rafts.

How odd that one of the world’s richest and most famous fossil sites isn’t on a mountain or in a desert, but in the heart of one of the world’s largest cities. In this episode, we’ll dive into the history of the La Brea Tar Pits, explore how the site came to be, and give just a taste of the staggering diversity of fossil finds that fuel research into the latest chapters of the Ice Age. Also, we’ll explain why “tar pits” isn’t really a great name for them.
In the news: a Cambrian Millennium Falcon, turtle bones, mammal ancestors, and a whale with a twist.

This episode, we take a deep dive into the evolutionary story of Earth’s largest land mammals. Extinction has left us with only three elephant species today, but for tens of millions of years their extended family, the proboscideans, came in many weird and wondrous forms, from mammoths to mastodons to shovel-tuskers and more.
In the news: clam secrets, weird bird feet, surprise Greek humans, and early hominin breastfeeding.

It’s Episode 65, and you know what that means … extinction! This time, we address the ancient and confusing Late Devonian extinction. This is traditionally considered one of the “Big 5,” but it doesn’t seem to be “one” extinction at all. Geologists and paleontologists continue to work at piecing together the various causes and consequences that create an extended series – several millions years long – of very unfortunate events that altogether comprise one of the worst biological crises in Earth history.
In the news: tyrannosaur smells, peccary behavior, and a talk (by us) about our podcast!

Can you picture paleontology without … pictures? For about as long as people have been digging up fossils, some have tried to recreate ancient organisms through art. Paleoartists combine artistic talents with detailed knowledge of life past and present to create their best hypotheses about the appearance of ancient species and ecosystems. Their work shows in the many images, animations, and sculptures that accompany research, museum displays, books, documentaries, and more. Paleoart is an inextricable piece of paleontology, and it’s all around us!

The history of animal life on Earth has been shaped by sex. The struggle to reproduce puts unique evolutionary pressures on species which affect their behavior and even their physical form. Sexual selection is immensely important but trying to sort out the side effects of sex in the fossil record is notoriously tricky.

Part 1 of 5 in this month’s series: KaiJune!
There’s a new Godzilla movie, and that means it’s time for more movie science! All June, we’ll be exploring giant monster movies, centering around two of the most famous examples of all time: King Kong and Godzilla. How do these movies handle such subjects as prehistoric creatures, the science of paleontology, and the portrayal of scientists?
This episode, we begin where it began: King Kong (1933).

It’s easy to see how fossils can teach us what ancient animals looked like, or how they evolved. But what about the ways they moved, ate, socialized, reproduced? In this episode, we explore the innovative ways paleontologists have devised to interpret the behavior of ancient animals. From their bones, their tracks, their living relatives, and modern clever experimentation, we can come to understand more than you’d ever imagine about behavior in the fossil record.
In the news: a Denisovan jaw, a new bat-winged dinosaur, a cave of wonders, and a flapping robot.

Turtles are so weird and wonderful. They're unlike any other living reptiles, mostly because they've turned their entire torso skeleton into an armor-home. A glimpse into the fossil record reveals that they've been this way for more than 200 million years. And yet, with all our data on living and extinct turtles, they remain one of the most mysterious and confusing living vertebrate groups. Here's an episode about all of that.
In the news: death rolls, one huge predator, one weird crab, the Gray Site rhino, and a poop snake.

Many groups of life have conquered the land and water, but only four times in evolutionary history has life taken to the air. The most recent group to achieve flight are bats. Their combination of flight and advanced echolocation have earned them an incredible diversity, a worldwide distribution, and a deep-seated place in human culture, but their evolutionary history is a long-standing mystery, and their fossil record is nearly non-existent. But that's not going to stop us from geeking out about them!
In the news: dinosaur scales, diverging crows, a new human, seal evolution, and that butchered mastodon again!

It was the late 1800s, and paleontology was just getting started in the Americas. Two prolific and passionate scientists, Edward Drinker Cope and Othniel Charles Marsh, among the earliest prominent fossil researchers on the continent, struck up a legendary rivalry. Their battles took place in the field and in the literature, and over three decades they engaged in some of the nastiest and most petulant quarreling in scientific history. This infamous era in early paleontology became known as The Bone Wars.
In the news: an egg in an ancient bird, a new mastodon, a giant T. rex, and the day the Cretaceous ended.

Look who's back - our favorite paleobotanist, Aly Baumgartner!
And that means it’s time for more plants! As you may have noticed, the world around you is absolutely full of flowers. Angiosperms have dominated nearly every terrestrial ecosystem on the planet, but the story of their early evolution is a famous conundrum. Darwin called it an “abominable mystery,” but there are some tantalizing clues as to how this group of plants got their start and then evolved to the incredible diversity we see today.
In the news: new Cayman mammals, louse camouflage, a geologic orrery, and language evolution.

One of the main themes of this podcast is the evolutionary history of life. This concept is familiar to all of us today, but our current understanding of evolution is the culmination of a very long history of scientific inquiry. In this episode, we’ll introduce you to some of the biggest names in this story, from Aristotle to Darwin, as we explore the evolution of evolutionary theory.
In the news: tiny frogs, an ancient nesting ground, algae evolution, and a tusked sea cow.

Usually, when we talk about mass extinction, we’re referring to events long past. But scary levels of extinction are a fact of our current world, as well. So much so that current events have been labeled the "Sixth Extinction.” In this episode, we discuss just how bad our current ecological crisis is, what’s causing it, and whether or not it truly deserves to be called a mass extinction. We also discuss what’s already being done – and what we can all do – to counteract catastrophe. It’s a depressing one, folks, but all isn’t lost. Stay informed and stay hopeful!
In the news: a new island, ancient turtle cancer, megalodon extinction, and that one Archaeopteryx feather.

Happy Darwin Day! Last year around this time, we were joined by Dr. Sarah Bray to discuss the life and times of Charles Darwin. This time, Sarah joins us again to discuss his colleague and natural selection co-discoverer, Alfred Russell Wallace. In 1858, the year before Darwin published his famous book, he received a letter from a young, adventurous, sometimes tragic man in the throes of illness in southeast Asia. To Darwin’s shock, the letter included precisely the same biological insights he had been working on. That letter came from Alfred Russell Wallace.

It's been called the most diverse of all bones. It comes in an incredible variety of shapes and sizes, living and fossil, scattered across the mammalian family tree. It's called the baculum, the os penis, and in this episode we discuss what it does, who has it, what it means for paleontologists, and the evolutionary processes that made it what it is today.

What did dinosaurs sound like? How did extinct animals make and use sound? Like most behaviors, noises don’t fossilize, but there is some tantalizing evidence that paleontologists have pulled together about fossil bioacoustics. In this episode, we discuss how pop-culture may have misled us, and how scientists have gathered actual clues from living animals and the fossil record – and have even made scientifically-inspired ancient audios! – to reconstruct the sounds of the past.

Many times in the history of life on Earth, reptiles have returned to the oceans. There were three famous groups of marine reptiles during the Mesozoic, and in this episode, we’re discussing the last to evolve, the shortest-lived, and the greatest (in David’s opinion, anyway) of them. We’ll tell the tale of how one group of lizards evolved to dominate waters around the world during the reign of the mosasaurs.
In the news: hunting sabertooths, very strange feathers, megalodon temperature, and feathered(?) pterosaurs.

It’s no secret we love paleontology; it’s a fascinating field of study. But sometimes our favorite subject is polluted and perverted by fraud. In this episode, we’re talking about fake fossils: why they happen, how they happen, and what effect they have on the paleontological community as a whole. And then it’s story time, where we review some of history’s most famous fossil fakes.
In the news: an early long-neck, tiny footprints, a huge dicynodont surprise, and the marsupial lion.

Synapsids are a vast group of animals that includes only one living lineage: us mammals. But for about 100 million years before true mammals evolved, ancient synapsids were not only incredibly diverse, but dominant in ecosystems around the world. In this episode, we’ll explore some of this incredible variety of “proto-mammals” and track the long evolutionary transition that produced all the familiar traits that make us mammalian.
In the news: a new living croc, a carnivorous herbivorous dinosaur, strange old footprints, and fish origins.

Welcome ... to Spookulative Evolution.
It's October, so we're exploring some more speculative evolution with a spooky twist! Each week this month, we'll be choosing a creepy creature and discussing how it - or something like it - might evolve biologically, pulling inspiration from the critters of the real world.
In this particularly disturbing episode, we consider mindless decomposing humans and parasitic host manipulation. How can we naturally arrive at a contagion that converts people into flesh-eating hoards? Our creature to create: Zombies.

Human culture is full of stories of marvelous creatures hiding in the wilds on the fringe of our understanding. Some are the stuff of local lore while others are world-famous, and some are even thought to be relicts of the distant past. The search for these “hidden animals” can be dramatic, sometimes controversial, and often less-than-scientific. It is the fascinating field of Cryptozoology.
In the news: a tiny dino skull, a fish-bitten pterosaur, evolution in darkness, and a history of kangaroos.

252 million years ago, the Earth experienced what might be the worst extinction event of all time, so dramatic that it brought an end to the entire Paleozoic Era, that it resulted in the rise of entirely new types of ecosystems, and that it has come to be known as “The Great Dying.” This episode, we discuss the tragedy, the chaos, and the aftermath of the Permian Extinction.
In the news: the oldest animal, giant elephant birds, mammal jaw evolution, and one really big tree.

Will and David recently attended SciFest: Rock, Fossil, Quake! This was an event held at the St. Louis Science Center in collaboration with the Washington University School of Medicine.
The event brought scientists and science enthusiasts face-to-face to talk about geology, earthquakes, and - most exciting for us - fossils (mostly dinosaurs)!
In this episode, we recount some of our impressions and favorite parts of the event, and include interviews with six dinosaur paleontologists who attended the event. You'll hear from:
Dr. Ashley Morhardt, Washington University
Dr. Andy Farke, Raymond Alf Museum
Dr. Denver Fowler, Badlands Dinosaur Museum
Dr. Casey Holliday, University of Missouri
Dr. Liz Freedman Fowler, Dickinson State University
Josh Matthews, Burpee Museum
Huge thanks to all of the above - and everyone else involved in the event - for a fun day of science outreach!

For tens of millions of years, North and South America were separate sisters across the sea, each with their own unique ecosystems. But around 3 million years ago, the Isthmus of Panama brought the landmasses together and kicked off an incredible mass migration of life between the continents. Some species thrived, others suffered, and in the end the very ecosystem structure of both continents was drastically altered, setting the stage for the American wildlife we know today.
In the news: prehistoric parasites, early turtle evolution, teeth through time, and a surprising hominin hybrid. Also, a devastating museum fire in Brazil.

There have been several times in evolutionary history where a land-dwelling group has transitioned to life in the water, but few have done it so successfully as the cetaceans. Not only are modern whales diverse and fascinating, but their ancestors have left behind an incredible fossil record of their transition into the sea. All that and more as we discuss the Evolution of Whales.

The island of Madagascar, isolated from all other landmasses on Earth, hosts one of the planet’s most unique ecosystems. But it’s not just an interesting place today – the geologic and fossil history of this land is equally fascinating! In this episode, we take a tour through time, stopping off at some of Madagascar’s most magical moments to marvel at some truly unique and incredible assortments of life.
In the news: an early giant dinosaur, more on human origins, ancient fish appendages, and a baby snake in amber!

This episode, we’re discussing the fun and fascinating “What If” thought experiments of evolution. From fantastical fictional stories to unusual scientific hypotheses to just-for-fun artistic creations, speculative evolution is all about exploring the unseen (and maybe never-to-be-seen) possibilities of real biological science. We’ll touch on some of our favorite “hard science fiction” as well as how this style of creative thinking can contribute to the study of real living creatures of the past ... and beyond.
In the news: Native American dogs, Neanderthal hunting methods, mammal testicle evolution, and plant-induced insect development.

At long last, a plant episode!
Our friend Aly Baumgartner joins the podcast to teach us all about grass - it's not just part of the background! From humble beginnings during the Age of Reptiles, grasses have gone on to dominate global ecosystems (as well as human diet!) and continue to do so today. They are truly one of the most influential groups of life on Earth.
In the news: strange ancient reef fish, dinosaur tongues, a surprise extinct gibbon, and a history of primate claws.

Surprise!
We've gotten a lot of bird requests, so to follow up our Evolution of Birds discussion, we put together three mini-discussions based on other birds our listeners have asked to hear about:
1. The evolution and fossil history of flamingos.
2. The fossil record of the famous predatory "terror birds."
3. Argentavis and Pelagornis, history's largest flying birds.

Animals don’t start their lives as tiny copies of adults; there are all sorts of changes that a creature goes through from fertilization to birth and from newborn to mature. This development is called ontogeny. In this episode, we discuss how ontogenetic change impacts animals as they grow, what we can learn from these patterns, and how ontogeny can cause confusion in the fossil record.
In the news: colorful moth fossils, an enormous ichthyosaur, Neanderthals' strange faces, and sea turtle navigation.

Everybody poops! Throughout the history of life on Earth, animals of all lifestyles have been littering the planet with little presents, and those few that fossilize become coprolites: unique time capsules that can serve as invaluable sources of information, not just on obvious stuff like ancient diets, but also about evolution, extinction, and more. This episode: we talk turds.
