The densest concentration of Jurassic-aged dinosaur bones ever found

Visit the site of the densest concentration of Jurassic-aged dinosaur bones ever found.

More than 12,000 bones from at least 74 individual prehistoric animals have been excavated here. See replicas of a dinosaur skeleton and dinosaur skulls, explore hands-on exhibits, and visit an excavation pit where you’ll see dinosaur bones preserved in the mudstone just below your feet. Visitors can also examine the rib of a large sauropod along the “Rock Walk” interpretive footpath, or hike the Raptor Point Trail for a bird’s-eye view of the quarry.

The Cleveland Lloyd Dinosaur Quarry is also stop along the Dinosaur Diamond Prehistoric Highway. Learn more about this national scenic byway at the Museum of the San Rafael or the John Wesley Powell River History Museum.

This is a working quarry where scientists conduct ongoing research. Visitor facilities are open daily during the summer and Thursday thru Sunday during spring and fall. They close for the season at the end of October and reopen in March.
