Acrocanthosaurus atokensis Skull Poster

Acrocanthosaurus is a theropod dinosaur in the family Carcharodontosauridae within the superfamily Allosauroidea. Only four Acrocanthosaurus specimens have been found, all from Texas and Oklahoma. The arms and shoulders of Acrocanthosaurus are much larger and more heavily muscled than the arms of Tyrannosaurus rex. Acrocanthosaurus has extremely long vertebral spines along the neck, body, sacrum and proximal tail. Preparation of this specimen was notably more difficult than many dinosaurs due to the abundant pyrite (iron disulfide), which added thousands of hours to the preparation. The skull is one of the most complete dinosaur skulls preserved in any girdles.museum.Acrocanthosaurus was the terror of the Early Cretaceous in North America.
