Dinosaurs first appeared at the end of the Middle Triassic or in early Late Triassic time, approximately 230 million years ago.The primitive dinosaurs of the Triassic were neither as abundant nor as varied as they would become in Jurassic and Cretaceous times. The fluvial (stream-deposited) sediments of the Morrison Formation dominated the Upper Jurassic landscape of eastern Utah. Originating approximately 150 million years ago as floodplain deposits, the Morrison Formation is exposed throughout the Colorado Plateau, including Colorado, Wyoming, eastern Utah, northern New Mexico, parts of Montana and South Dakota, and the panhandle of Oklahoma.
