 This exhibition showcases the evolutionary history of vertebrates, including spectacularly preserved fishes, dinosaurs, and diminutive early mammals. Highlights include the world’s only mounted *Kronosaurus*, a 42-foot-long prehistoric marine reptile, one of the first *Triceratops* skulls ever discovered, and a huge *Pteranodon*, a fish-catching flying reptile from the Cretaceous period.
