Allosaurus, yes, the bully groups that massacares everything on their way, i'm not sure if Allosaurus are supposed to be in groups, but fun fact: these creatures are pretty big and is one of the top predator in the jurassic era, it eats alot of things which is pretty obvious, but these big bois are not exactly as aggressive as they are in Ark, still Ark makes a pretty accurate interpretation of these dudes, still, those groups.. damn, feels like a group of bully you encounter in school lmao
