Mosasaurs were a type of marine reptile that lived during the time of the dinosaurs. These massive creatures ruled the oceans, feeding on fish, squid, and even other marine reptiles.
Mosasaurs were known for their powerful tails, which allowed them to swim quickly and catch their prey off guard. They also had sharp teeth and strong jaws, making them apex predators in their ecosystem.
Mosasaurs lived in warm, shallow waters during the Cretaceous period. They likely spent most of their time near the surface, where they could hunt and bask in the sun.
