Steve Brusatte (The Rise and Reign of the Mammals) is a paleontologist and author. Steve joins the Armchair Expert to discuss the process of finding dinosaur bones, how mammals survived during the time of the dinosaurs, and how likely it is to bring back the woolly mammoth. Steve and Dax talk about what some of the largest mammals would have looked like, how Thomas Jefferson was obsessed with natural history, and how evolution has shaped what today's mammals are. Steve explains how the dinosaurs most likely died off, that dinosaurs most definitely had feathers, and that blue whales have belly buttons.
