-Mosasaur: was a 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.The 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 moveable 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. They date back to about 65 million years ago..
-Elasmosaur: Elasmosaurs descend from the Plesiosauia family, they flurished back in the late cretaceous age about 69-66 million years ago; they can be found in North America and Africa; they may have weighed up to 5100 lbs or 2.3 tons and they reached about 45 fee in length; their primary diet consisted of fish. The Elasmosaur was the longest member of the elasmosaur family and in fact, the longest-known plesiosaur. It was a marine reptile, swimming in the shallow Mesozoic seas. More than half of its total length was neck - 26 feet (8m) out of a total 45 feet (14m). Its neck had 71 vertebrae, many more than the earliest plesiosaurs, which had about 28 neck vertebrae. The neck probably served to move the head towards the prey with a very rapid darting movement. The head was relatively small, and the jaws had sharply-pointed teeth for catching fish. All our Elasmosaur fossils were found in the phosphate mines of Oued Zem Morocco.
-Pliosaur: (pronounced PLY-oh-SAWR) Pliosaurs (meaning "greater lizard") were huge, short-necked plesiosaurs. These flippered marine reptiles were carnivores with sharp teeth in large, powerful jaws. They may have eaten ichthyosaurs and other plesiosaurs. They lived during the Jurassic and Cretaceous periods.Some Pliosaurs include Peloneustes, Macroplata, Kronosaurus, and Liopleurodon. Our Pliosaur fossils were found in the Sahara desert in Moroccoo, and they date back to the cretaceous period (115-95 million).
