Dinosaurs are often thought of as aggressors—giant beasts that dominated our planet for millions of years. But these prehistoric animals almost certainly had a softer side. In the last decade, researchers have gained tantalizing insights into the sex lives and mating habits of these ancient reptiles.

In this episode, Smithsonian contributing writer Riley Black describes new evidence that reveals how and when dinosaurs mated—including ancient behavior recorded in rock, a new theory around dinosaur horns and spikes, and a prehistoric cloaca.
