hunting ground, holding fossils of green algae, fungi, mosses, horsetails, ferns, cycads, ginkgoes, and several families of conifers. Other fossils discovered include bivalves, snails, ray-finned fishes, frogs, salamanders, turtles such as Uluops, sphenodonts, lizards, terrestrial and aquatic crocodylomorphans like Fruitachampsa, several species of pterosaur like Kepodactylus, numerous dinosaur species, and early mammals such as docodonts, multituberculates, symmetrodonts, and triconodonts. Such dinosaurs as the theropods Ceratosaurus, Allosaurus, Ornitholestes, and Torvosaurus, the sauropods Apatosaurus, Brachiosaurus, Camarasaurus, and Diplodocus, and the ornithischians Camptosaurus, Hesperosaurus, Nanosaurus, Fruitadens, Dryosaurus, and Stegosaurus are known from the Morrison. Coelurus is regarded as a small terrestrial carnivore, feeding on small prey items like insects, mammals, and lizards. It is thought to have been a fast animal, certainly faster than the similar but shorter-footed Ornitholestes. Coelurus is present in stratigraphic zones 2 and 5 of the Morrison Formation. Notes Not the same as the human lunate bone, but a wrist element with a half-moon shape. References External links Coelurus from Palaeos.com.
