Mosasaurus hoffmannii

Part of the ANCIENT WATERS Exhibit

Late Cretaceous Period, approx. 82-66 million years ago

1:4 Scale Skull Replica

SPECIMEN PROFILE

Mosasaurus hoffmannii was a gigantic marine lizard that dominated the oceans of the Late Cretaceous, occupying the role of apex predator in coastal seas and inland marine environments. As one of the largest mosasaurs, it represents the peak of evolutionary specialization among marine squamates.

Its elongated body was powered by a strong, muscular tail adapted for rapid lateral propulsion, while its limbs had evolved into paddle-like flippers for steering and maneuvering. The skull housed powerful jaws lined with conical, recurved teeth designed for gripping slippery prey, including fish, ammonites, and other marine reptiles. Evidence also suggests a highly flexible skull structure, allowing it to consume large prey items whole or in powerful bites.

COLLECTOR & CURATOR NOTE

A Late Cretaceous marine apex predator of immense scale—its powerful jaws and streamlined aquatic form represent the ultimate expression of mosasaur evolution in prehistoric oceans.
