This weekend, Steven Spielberg’s famous computer generated dinosaurs returned to theaters in Jurassic World: Fallen Kingdom. Directed by J. A. Bayona, it’s the fifth film in the popular Jurassic Park franchise.

But in the 25 years since the first Tyrannosaurs Rex stomped across the fictional Isla Nublar resort seen in Jurassic Park paleontologists have learned a great deal about the animal. Associate Professor Thomas Carr is one of the foremost experts on tyrannosaurid dinosaurs and the director of the Carthage College Institute of Paleontology in Kenosha.

Dr. Carr is preparing to leave next month on his latest expedition to Montana in search of Tyrannosaurus Rex fossils along with any number of its cretaceous contemporaries.

On CBS 58 Sunday Morning, Dr. Carr revealed his thoughts on what the films got right and what they got wrong.
