250 million years of dinosaur history, in 104 minutes

Steve Brusatte, the paleontologist behind Jurassic World's science and author of The Rise and Fall of the Dinosaurs and The Story of Birds, walks through what fossils actually prove versus what Hollywood invented. 

Brusatte traces dinosaurs back to footprints smaller than a house cat, found in Poland just after the worst mass extinction in Earth's history, and explains why those early survivors spent millions of years as background characters next to car-sized salamanders and armored crocodiles.
