where were allosaurus fossils found
Four inch long sharp teeth were also used to tear apart the dead and dying victims that were unfortunate enough to have been hunted by Allosaurus. Fossils found in Utah, North America, suggest that Allosaurus may have lived and hunted in groups or packs. As a pack, Allosaurus would have had little difficulty hunting the largest dinosaurs of the time. One fossil of a large plant-eating Apatosaurus has what look like the teeth marks of Allosaurus scraped into it.
