Allosaurus fragilis cast skeleton, Jurassic Period, Dinosaur National Monument, Utah, USA

Displayed at Quarry Exhibit Hall in Dinosaur National Monument, this Allosaurus fragilis skeleton is cast from bones of the Jurassic Period (149 million years ago) dug from the Cleveland-Lloyed Quarry in east-central Utah, USA. Allosaurus was the most common predatory animal in the Morrison Formation's ancient ecosystem. The theropod (meaning "beast-footed") dinosaurs are a diverse group of bipedal saurischian ("lizard-hipped") dinosaurs. Therapods include the largest carnivores ever to have walked the earth. Not all dinosaurs are extinct, since birds are actually the descendants of small nonflying theropods.
