Mosasaurus Jaw in Matrix

A well-preserved Mosasaurus jaw with a tooth still atached, embedded in its original matrix. While the crown has a few visible cracks it has been expertly stabilized for preservation.

No repair or restoration.

Mosasaurs, part of the family Mosasauridae, were the top ocean predators during the Late Cretaceous, around 66–70 million years ago. Think of them as giant, sea-dwelling lizards with powerful jaws and paddle-like limbs. The genus Mosasaurus, the namesake of the group, is among the most famous. Fossils found in Morocco offer a fascinating glimpse into their world, where they hunted fish, squid, and even other marine reptiles. These creatures truly ruled their ancient seas!
