Allosaurus fragilis

The razor-toothed Allosaurus as seen in Dinosaurs in Their Time at Carnegie Museum of Natural History. This giant meat-eating dinosaur once roamed the world 150 million years ago, long before Tyrannosaurus rex appeared. With razor-sharp teeth, hooked claws, and jaws that could expand to bite huge mouthfuls of flesh from victims, Allosaurus was one of the Jurassic Period’s ultimate hunters.
