Discovery: The Life Scientific: Steve Brusatte

Jim Al-Khalili talks to Professor Steve Brusatte about his life and work studying dinosaurs, mammals and ancient reptiles. Jim asks his guest to analyse the pace of evolutionary change and answer some big questions, such as why the dinosaurs died out while the mammals survived. Steve also discusses the recent discovery of an incredibly well-preserved Pterosaur on the Isle of Skye, a place he likes to call Scotland's `Jurassic Park"
