Allosaurus fragilis and the other species of the large genus Allosaurus are the dominant large predators of Jurassic North America.  Prowling alone or in packs, these ten meter carnivores can successfully hunt all but the largest individuals of their sauropod prey.

    Rather than take on the daunting task of grappling with one of the titanic sauropods, A. fragilis utilizes the slash-and-bleed hunting strategy of most large, carnivorous dinosaurs (Paul).  Large, serrated teeth slice through the flesh of a sauropod easily, cutting muscles and ligaments easily.  The sauropod, with its legs and belly bleeding from many shallow slashes, will collapse from blood loss (or succumb days later to infection) and will then be easily dispatched by hungry A. fragilis .
