They belonged to Squamata, the same major group that includes modern lizards and snakes. Mosasaurids ranged from relatively small forms to giant marine predators. They evolved a wide variety of tooth shapes adapted for grasping, cutting, or crushing prey, reflecting their diverse diets and ecological roles in Late Cretaceous marine ecosystems.
