Description: Deinonychus antirrhopus theropod dinosaur from the Cretaceous of Montana, USA (public display, MOR 747, Museum of the Rockies, Bozeman, Montana, USA). Deinonychus is a predatory dinosaur, frequently referred to by the Hollywood term "raptor". Deinonychus had multiple sharp claws on each hand (shown here) and a greatly enlarged claw on each foot, as did some other theropods like Utahraptor. Classification: Animalia, Chordata, Vertebrata, Dinosauria, Theropoda, Dromaeosauridae Stratigraphy: Cloverly Formation, Lower Cretaceous Locality: Carbon County, southern Montana, USA Theropod were small to large, bipedal dinosaurs. Almost all known members of the group were carnivorous (predators and/or scavengers). They represent the ancestral group to the birds, and some theropods are known to have had feathers. Some of the most well known dinosaurs to the general public are theropods, such as Tyrannosaurus, Allosaurus, and Spinosaurus.
