Acrocanthosaurus atokensis

Part of the APEX PREDATORS Exhibit

Early Cretaceous Period, approx. 115–105 million years ago

1:5 Scale Skull Replica

SPECIMEN PROFILE

Acrocanthosaurus atokensis was one of the dominant apex predators of Early Cretaceous North America. As a member of the carcharodontosaur lineage, it was built for power and slicing bite force rather than the bone-crushing adaptations seen in later tyrannosaurs.

Its most distinctive feature was the series of elongated neural spines along its neck, back, and hips, forming a pronounced ridge that likely supported strong musculature or a display structure. It hunted large herbivores across floodplain and river valley ecosystems, occupying the top tier of its food web.

COLLECTOR & CURATOR NOTE

A commanding apex predator from before the rise of tyrannosaurs—its tall spinal ridge likely served both display and muscular support functions.
