Dr. Steve Brusatte joins us for a paleontologist interview about The Story of Birds, exploring how birds survived the dinosaur extinction, evolved from dinosaur ancestors, and became one of Earth's most successful groups of animals.In this episode of I Know Dino, we cover new dinosaur discoveries and dinosaur research before sitting down with Steve Brusatte, paleontologist, author, and University of Edinburgh professor. We discuss what the fossil record reveals about bird evolution, why birds are living dinosaurs, and how paleontologists connect modern species to their dinosaur ancestors. Steve explains how scientists study dinosaur evolution, brain evolution, and the survival of bird lineages through the end-Cretaceous extinction.We also talk about giant fossil birds, terror birds, penguins that once rivaled large mammals, and how dinosaur research continues to reshape our understanding of prehistoric life. Along the way, Steve shares stories from his work as a researcher, science communicator, and author, including insights from writing The Story of Birds and helping connect modern bird biology to deep dinosaur history.Before the interview, we cover a new tiny alvarezsauroid from Argentina, discuss what it reveals about dinosaur evolution, and look at new research tools that help scientists reconstruct ancient environments and extinction events.Thanks for listening to I Know Dino: The Big Dinosaur Podcast—your source for dinosaur discoveries, dinosaur news, dinosaur research, paleontology news, and interviews with the scientists making new fossil discoveries.Steve Brusatte joins to discuss the only group of dinosaurs that survived the asteroid.

Zofia Kielan-Jaworowska was a Polish scientist and the first woman to lead a dinosaur excavation expedition.
