Dinosaur National Monument, National Park Service
Jensen, United States

Dinosaur National Monument is located on the southeast flank of the Uinta Mountains on the border between Colorado and Utah at the confluence of the Green and Yampa Rivers.

Dinosaur National Monument protects a large deposit of fossil bones of creatures that lived nearly 150 million years ago. The fossils help us learn more about these fascinating animals.

Dinosaur National Monument is special because visitors can see fossils exposed on the cliff face of the Douglass Quarry at the park visitor center. This site provides one of the best snapshots of Jurassic dinosaurs found anywhere in the world. The quarry was named after Earl Douglass, the paleontologist who found it.

Most great fossil deposits have been excavated until there's nothing left to see. That is not the case at Dinosaur National Monument. The National Park Service reopened the Douglass Quarry in the 1950s, not to remove all the fossils, but to develop them into a unique exhibit. The Douglass Quarry is enclosed within the park visitor center and museum. It offers visitors a unique opportunity to see over 1,400 fossil bones that have been left in place as nature deposited them 150 million years ago.
