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!
