Dinosaurs rule at the New Mexico Museum of Natural History and Science. That’s what we like best about the museum, which presents billions of years of New Mexico’s natural history. Yes, dinos one roamed “Route 66.” “Stan,” the second largest T-Rex ever found, reaches nearly 40-feet long and 12-feet high. He holds forth at “Dawn of the Dinosaurs,” one of the only hall’s dedicated to Triassic creatures in North America. These smaller ancestors of the Jurassic era’s thumping big boys tread the earth 251 million years ago. Find out about Phytosaurs, the top Triassic predator, a 32-foot long crocodile-like creature that lived in the area when the land was lush, filled with tropical plants and marshes instead of sandy deserts. Exhibits also describe New Mexico’s era as a seacoast.
