Acrocanthosaurus was the largest terrestrial predator of North America during the Early Cretaceous.
It had unusually high spines on its vertebrae that produced a tall thick ridge that ran the full length of its spinal column. A bipedal carnivore, it had a large, long head (4-5 ft) with a mouth filled with many thin, serrated teeth.
