Allosaurus jimmadseni

Part of the APEX PREDATORS Exhibit

Late Jurassic Period, approx. 155-145 million years ago

1:3 Scale Skull Replica

SPECIMEN PROFILE

Allosaurus jimmadseni was one of the earliest well-established apex predators of the Late Jurassic ecosystems of western North America. It inhabited semi-arid floodplains and forested river valleys, where it coexisted with large sauropods and ornithopods that formed the backbone of its prey base.

As an early species within the Allosaurus lineage, it exhibits many of the classic theropod adaptations for large-scale predation: powerful hindlimbs for pursuit, strong forelimbs with grasping claws, and a lightly built but reinforced skull optimized for slashing bites. It likely hunted both alone and in opportunistic groups, using ambush and coordinated pressure against large herbivores.

COLLECTOR & CURATOR NOTE
