Dinos of the Deep
Dive into prehistoric seas
Journey through the Western Interior Seaway, where massive mosasaurs, sharks, and savage marine reptiles dominated the age of the dinosaurs — beneath the waves. This exhibit features 36 specimen, including huge carnivorous marine reptiles, flying reptiles with the wingspan of a small airplane, gigantic flesh-eating fish big enough to swallow an adult human, and the biggest sea turtles to have ever lived.

Did you know?
If it flew in the air or lived entirely underwater, it’s technically not a dinosaur. Our pteranodons and mosasaurs, for example, are massive reptiles — but they lack the specific bone structure needed to be classified as part of the clade Dinosauria. The Cretaceous era was full of all sorts of fascinating creatures!
