Allosaurus

The allosaurus is a huge bipedal dinosaur built for hunting larger prey. Their legs are long and powerful, and their specially hinged jaw allows their mouth to open wide enough to attack creatures who tower over them and to gulp down smaller creatures with frightening ease. Their short arms are tipped in razor-sharp claws, and their thick tails can provide a powerful sweeping defense in a pinch. Occasionally, allosauruses live and hunt in small groups, working together to take down especially large prey. However, they prefer staying in their own territory, reigning over their prey within. Some of their known prey include the brontosaurus, stegosaurus, or whole livestock if an allosaurus strays too close to unprotected farmlands.
