Anzu wyliei Lamanna et al., 2014 theropod dinosaur from the Cretaceous of South Dakota, USA (public display, reconstruction based on CM 7800 & CM 78001, Carnegie Museum of Natural History, Pittsburgh, Pennsylvania, USA). This new, odd, toothless dinosaur had a bony, keeled crest on its skull and long, clawed hands. Classification: Animalia, Chordata, Vertebrata, Dinosauria, Theropoda, Caenagnathidae Stratigraphy: Hell Creek Formation, upper Maastrichtian Stage, upper Upper Cretaceous Locality: western Harding County, far-northwestern South Dakota, USA Reference: Lamanna, M.C., H.-D. Sues, E.R. Schachner & T.R. Lyson. 2014. A new large-bodied oviraptorosaurian theropod dinosaur from the latest Cretaceous of western North America. Public Library of Science One ("PLOS ONE") 9(3): e92022. 16 pp. 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. — Ενδεικτική φωτογραφία / φωτογραφία αρχείου — Anzu wyliei Lamanna et al., 2014 theropod dinosaur from the Cretaceous of South Dakota, USA (public display, reconstruction based on CM 7800 & CM 78001, Carnegie Museum of Natural History, Pittsburgh, Pennsylvania, USA).
