Mosasaurs were giant, meat-eating marine reptiles ( it is not a dinosaur) that lived during the late Cretaceous period. It was up to 33ft (10 m) long. Mosasaurs had four paddle-like limbs on a long, streamlined body and a long, powerful tail. They had a large head had huge jaws (up to 4.7 ft =1.45 m long) with many teeth. The jaws could open about 3 feet (1 m). The lower jaw is loosely hinged to the skull with a movable joint on each side (behind the teeth). This loose joint let it swallow huge prey, like some snakes. They hunted fish, turtles, mollusks, and shellfish. Our Mosasaur fossils were found in the Phosphate mines of Khouribga, Morocco. This Mosasaur tooth belonged to a Prognathodon mosasaur, it is exceptionally large and well preserved.
