[edit]DescriptionTyrannosaurus rex (theropod dinosaur lower jawbone) (Late Cretaceous, western USA).jpg |
English: Tyrannosaurus rex Osborn, 1905 - theropod dinosaur mandible from the Cretaceous of western USA. (public display, Red Rocks Amphitheater visitor center, west of Denver, Colorado, USA)
Theropods 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. Tyrannosaurus rex is the most famous theropod dinosaur. It was a large bipedal predator in western North America 65 to 68 million years ago, during the latest Cretaceous (Maastrichtian Stage). Classification: Animalia, Chordata, Vertebrata, Dinosauria, Saurischia, Theropoda, Allosauria, Tyannosauridae, Tyrannosaurinae Stratigraphy: unspecified unit, Maastrichtian Stage, upper Upper Cretaceous Locality: unspecified |
