The area is rich in geological history going back 2 billion years. The national park was founded in 1906 to protect the Anasazi Native American sites found on the mesa tops, cliffs, and canyons. The exposed areas found in the park are from the Mesozoic Era, Cretaceous Period (about 100-78 million years ago). They make up four formations: Cliff House, Menefee, Point Lookout, and Mancos.

A colleague of mine recently returned from a vacation to Montana.When he was showing me pictures from his trip I found the one shown in this post intriguing. It turns out this Tyrannosaurus rex fossil replica is on display at the baggage display area of Bozeman Yellowstone International Airport of Belgrade, Montana. Montana is the source of many dinosaur fossils so it seems fitting they chose this replica to represent an aspect of Montana geological past.
This dinosaur existed in the upper Cretaceous Period (68-66 million years ago; Maastrichtian). Learn more at Wikipedia.
Thanks to Ryan for the picture.
