Paleontologists have identified an ancient reptile with a towering crest made not of skin, or scales, or feathers, or antler—but something else entirely. It’s some kind of integumentary outerwear we’ve never seen before. The small creature sporting the curious crest was named Mirasaura grauvogeli, and it lived during the Middle Triassic period, about 247 million years ago, just before dinosaurs evolved.
Host Flora Lichtman talks to evolutionary biologist Richard Prum about this dramatic dorsal mystery and what it tells us about the evolution of dinosaurs, birds, and feathers.

Plus, how fast did dinosaurs run? It turns out that the equation scientists have been using for five decades to estimate dinosaur speeds is not completely accurate. To understand what this could mean for velociraptor velocities, T. rex tempos, and spinosaurus speeds, Flora talks with paleobiologist Peter Falkingham.
Guests: Dr. Richard Prum is a professor of ecology and evolutionary biology and head curator of ornithology at the Peabody Museum of Natural History at Yale University in New Haven, Connecticut. He previously chaired Yale’s Department of Ecology and Evolutionary Biology.
Dr. Peter Falkingham is a professor of paleobiology at Liverpool John Moores University in England.
