Some recent discoveries have shed light on many details of the anatomy of Acrocanthosaurus, especially studies focusing on the brain structure and function of the forelimbs. Acrocanthosaurus may have held its prey in its jaws, while repeatedly grabbing it with its forelimbs, tearing and slashing with its claws. Acrocanthosaurus was the largest theropod for its ecosystem and likely the top predator. Its possible prey were large sauropods and ornithopods. The Glen Rose Trackway from Texas on display in New York City includes theropod footprints that may have been made by several Acrocanthosaurus stalking twelve sauropod dinosaurs.
