Ceratosaurus nasicornis

Part of the APEX PREDATORS Exhibit

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

1:2 Scale Skull Replica

SPECIMEN PROFILE

Ceratosaurus nasicornis was a distinctive mid-to-large theropod of the Late Jurassic ecosystems of North America, inhabiting river valleys, coastal plains, and forested flood basins. It coexisted with larger apex predators such as Allosaurus, occupying a flexible predatory niche that likely included both active hunting and opportunistic scavenging.

Its most recognizable feature is the prominent nasal horn, paired with a row of small osteoderms running along the midline of its body. Unlike more lightly built contemporaries, Ceratosaurus had a deeper, more robust skull and powerful jaws suited for gripping and tearing flesh. Its anatomy suggests a predator capable of both ambush and direct confrontation, particularly in dense or enclosed environments where agility and intimidation were key advantages.

COLLECTOR & CURATOR NOTE
