blurb - Allosaurus was a large bipedal carnivorous dinosaur measuring up to 12 m (39 ft) long. It was named 'different lizard' because its vertebrae were different from those of all other dinosaurs. It was the most common large predator in what is now North America, 155 to 145 million years ago, in the late Jurassic period. It shared the landscape with several genera of giant sauropods such as Apatosaurus, Diplodocus and Camarasaurus, as well as other herbivores such as Stegosaurus and Camptosaurus, all of which Allosaurus may have preyed upon. The fossil remains of smaller species resembling Allosaurus and dating from the Early Cretaceous of North America, Australia and Japan supports the hypothsis that it survived the mass extinction at the end of the Jurassic, some 144 mya.
