Utah is the site of the earliest Morrison dinosaur discovery, Dystrophaeus viaemalae, a sauropod dinosaur discovered on the 1859 Macomb Expedition to southeastern Utah.

Although Utah is most famous for its Morrison Formation dinosaur fauna, Utah has a prolific fossil record that spans the entire \"Age of Dinosaurs.\" The dinosaurs thrived for over 150 million years.

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.

The well-known Morrison dinosaur fauna includes Utah\'s official state fossil, the meat-eating theropod Allosaurus; other theropods, including Ceratosaurus, Stokesosaurus, and Marshosaurus; the sauropod dinosaurs Apatosaurus (commonly known as Brontosaurus), Camarasaurus, and Diplodocus; and the ornithischians Camptosaurus, Dryosaurus, and Stegosaurus.
