Illustrative image: The Upper Jurassic Morrison Formation is widely distributed in many western American states. The unit consists of fluvial (river/floodplain) and lacustrine (lake) deposits. Dinosaur bones and dinosaur tracks are moderately common in Morrison Formation sediments. Exceptionally dinosaur-rich localities include Como Bluff in Wyoming, Dinosaur National Monument in Utah, Dinosaur Ridge in Colorado, and the Cleveland-Lloyd Quarry in Utah.
