<pictures coming>Allosaurus was roaming the western North- America, East - Africa and Southwest of Europe in Late Jura. Small adult animals weighed as much as a large draught horse, like Shire, while the larger Adults grew to weigh as much as an elephant. Individuals of different sizes may have been different species. Some Scientists once believed that the larger individes came from an entirely different family. Allosaurus haunted herbivores like the twolegged Camptosaurus and the fourlegged Dinoes Stegosaurus and Apatosaurus. It probably hunted by luring in the bushes until the slow herbivore passed by.
