Mosasaurus Skull Fossil

This is a Mosasaurs' skull fossil, a large marine reptile that lived during the Late Cretaceous period, about 70–66 million years ago. They were powerful ocean predators. The long snout and sharp, cone-shaped teeth were used to grip slippery prey such as fish, squid, and other marine reptiles. This skull shows the strong jaw structure and tooth placement that made mosasaurs dominant hunters in prehistoric seas.
