Dinosaur National Monument

The Carnegie Exhibit Hall is the building that houses the dinosaur quarry including the wall of bones. These are the fossilized remains of ten different types of dinosaurs who lived during the late Jurassic Period, about 150 million years ago. The Carnegie Exhibit Hall and the Quarry Visitor Center are open every day of the year with the exception of Thanksgiving Day, December 25, and January 1.
