New Mexico's Seacoast

Cretaceous Period, 144 million to 66 million years ago

This recently expanded and upgraded hall reopened in 2003. It features a time when most of New Mexico was covered by an inland sea and urges you to consider what New Mexico was like 75 million years ago.

The exhibit features a living tropical forest and fossils of marine animals, strange birds, early mammals, and dinosaurs. The dinosaur fossils include a jawbone with teeth from a T. rex, a partial skeleton of the tyrannosaur Daspletosaurus, and skulls of many other dinosaurs, including Parasaurolophus, Naashoibitosaurus, Sphaerotholus, and a tyrannosaur known as "The Bisti Beast".
