Dinosaur National Monument

Uintah, Utah, United States

Dinosaur National Monument on the Utah–Colorado border protects the Carnegie Quarry, where Earl Douglass found the Morrison sauropod bonebed in 1909, now displayed as a wall of bone in the Quarry Exhibit Hall. It is the best place to see Morrison bone as it lies, and a reminder that the same formation on private Wyoming and Colorado ranches is where legal trade material comes from.
