Episode 174: A History of Dinosaurs in 50 Fossils

Prof. Paul Barrett of the Natural History Museum, London, recently authored A History of Dinosaurs in 50 Fossils. We took this as an opportunity to get an overview of what we really know about dinosaurs and how it's even possible to tell their story with just 50 specimens. In this episode, Paul discusses the history of dinosaur research, the current state of the science and what are still some of the big unknowns.
