Dinosaur of the day Avimimus, the bird mimic of bird mimics.

In dinosaur news this week:

• A new Early Jurassic theropod skeleton gives more insight into how theropods evolved
• There’s a new enantiornithine, Plumadraco bankoorum, and it had really long tail feathers
• There is a new enantiornithine, Gorgonavis alcyone, and it had a long beak
• Paleontologists found an extra large tyrannosaur shinbone in New Mexico, which may show Tyrannosaurus evolved in North America
• A study of the tiny hyoid bone (in the mouth) in Nanotyrannus supports that it is a valid dinosaur
• How and what theropods ate changed over time as their skulls evolved—a new study breaks down the theropod group changes
• Five different carnivorous non-avian theropod groups evolved to have shorter arms and bigger heads (not just T. rex)

Spinosaurus mirabilis has a head unlike any other spinosaur with possibly the tallest head crest of any non-avian dinosaur. Plus, Jeff Bond joins from Ogden's George S. Eccles Dinosaur Park to discuss what it's like running a museum with animatronics, fossils, a prep lab, sculptures, and (in the near future) puppets!

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. Plus a new alvarezsauroid which is the most complete and smallest dinosaur ever found in South America.
