I Know Dino: The Big Dinosaur Podcast22 Jan 2015

Tyrannosaurus rex and Pete Larson on Sue, T. rex Behavior, and Dinosaur Science

What does the fossil evidence really tell us about Tyrannosaurus rex? Pete Larson explains T. rex research, behavior, hunting, parenting, fossils, and the science behind one of history's most famous dinosaurs.

Tyrannosaurus rex is one of the best-known dinosaurs, but new dinosaur research continues to reshape what scientists know about how it lived. In this episode, paleontologist Pete Larson, president of the Black Hills Institute and leader of the famous Sue excavation, explains what decades of fossil discoveries have revealed about T. rex.

We discuss the evidence behind the predator-versus-scavenger debate, whether Tyrannosaurus rex may have hunted in family groups, how scientists study dinosaur behavior from fossils, and what discoveries suggest about parenting, feathers, biomechanics, growth, and sexual differences. Pete also shares how new paleontology research changes long-held ideas as additional fossils are discovered and studied.

Interview with Pete Larson from the Black Hills Institute and a discussion of the new movie "Dinosaur 13" which details the discovery and legal battle over the T. rex Sue.
