Episode 92 - Eggs

127 min • 26 juli 2020

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.
