Episode 402 - Feathers on Dinosaurs and Pterosaurs

October 26, 2020

We dive in to the debate around feathers on dinosaurs and pterosaurs. When did the first feathers develop? How did they form and what was their connection to modern birds? What can we learn by studying the feathers of modern birds and dinosaurs? Did Pterosaurs have feathers? Why would pterosaurs feathers upend our understanding of feathered dinosaurs? What colour where archaeopteryx feathers? How different were the feathers of archaeopteryx from modern birds?
