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.The picture shows tectonically tilted beds of the Morrison Formation in Dinosaur National Monument, Utah.
