Allosaurus

phylum	Chordata	Allosaurus /ˌælɵˈsɔrəs/ is a genus of large theropod dinosaur that lived 155 to 150 million years ago during the late Jurassic period. The name "Allosaurus" means "different lizard". It is derived from the Greek ἄλλος/allos ("different, other") and σαῦρος/sauros ("lizard / generic reptile"). Allosaurus was a large bipedal predator. Its skull was large and equipped with dozens of large, sharp teeth. It averaged 8.5 m (28 ft) in length, though fragmentary remains suggest it could have reached over 12 m (39 ft). Relative to the large and powerful hindlimbs, its three-fingered forelimbs were small, and the body was balanced by a long and heavily muscled tail. For more information, visit the Wikipedia entry.
