The Cleveland-Lloyd Dinosaur Quarry at Jurassic National Monument is located at 5800 feet. The site is one of the world`s most impressive collections of dinosaur bones and fossils from the Jurassic Morrison Formation. Over 12,000 bones from at least 70 different prehistoric critters have been excavated here. These bones have been reassembled and displayed in museums throughout the world. More to the point is the fact that the deposit is the densest concentration of Jurassic dinosaur bones ever found.

There is a self guided nature walk, and the visitor center is staffed by the BLM through the use of employees and volunteers. The restrooms and the trail at the quarry are accessible.

Operating hours for the 2022 season are 10am-5pm Thurs-Sunday, March 31 until October 30.
