Highlights from the Cretaceous

During the Cretaceous, seas covered parts of New Mexico, and along their shorelines lived some of the last dinosaurs. This exhibit explores the interplay of land and sea environments in Cretaceous New Mexico that preceded the final extinction of the dinosaurs.

Below are some of the features in the New Mexico's Seacoast exhibit.
