New Fossil Shows Birds Weren’t the Only Dinosaurs to Evolve Flight
Summary
Paleontologist Steve Brusatte discusses the discovery of Nurellraptor, a four-winged feathered dinosaur that suggests bird-like flight may have evolved independently in multiple lineages. The episode explores the history of the dinosaur-bird connection, from Huxley’s early theories to the pivotal Chinese fossil finds, and examines why modern birds survived the asteroid impact while other dinosaurs perished. Brusatte also highlights evidence of complex dinosaur behaviors, such as brooding, and shares the remarkable story of the Berlin Archaeopteryx being traded for a cow.
