Recent discoveries reveal new clues about the evolution of T. rex from a small fuzzy carnivore to one of the largest predators ever to walk the Earth. Studies of the tyrant king’s eyes, nose, brain, claws, jaws, teeth, and legs create a clearer picture of how T. rex lived, fed, and fought. We can now map changes in growth and behavior that Tyrannosaurus went through from birth to death.


Dr. Thomas Holtz is a dinosaur paleontologist specializing in the origin, evolution, and adaptations of carnivorous dinosaurs. In this talk he will show us how recent studies of T. rex as well as other dinosaurs, animals and plants that shared his world, reveal how the last of the giant dinosaur predators ruled North America at the end of the Age of Dinosaurs.
