The point of tiny T. rex arms and other dinosaur mysteries

What do we really know about the sounds dinosaurs made or what T. Rex did with its tiny arms? David Hone, paleontologist and senior lecturer at Queen Mary University of London, joins host Krys Boyd to discuss the latest in dinosaur research, from child-rearing to habitats  and what might be the next big dinosaur discovery on the horizon. His book is “How Fast Did T. Rex Run? Unsolved Questions from the Frontiers of Dinosaur Science.”
