3D picture presents a skeleton of Plesiosaurus, a genus of flippered marine reptiles that lived during the early Jurassic period. They were not dinosaurs, but plesiosaurs, marine reptiles from the Mesozoic Era. Plesiosaurus means “near lizard.” These streamlined reptiles were roughly 2.3 m long and may have weighed about 90 kg.
They had four wide, paddle-shaped flippers, used to propel the Plesiosaurus through the water with great maneuverability, and a tapered body. The head was relatively small. They had many long, sharp, conical teeth in long wide jaws which were efficient at trapping prey. It used its intermeshing teeth to catch its food. It did not chew it, but it swallowed food whole. It looks like Plesiosaurus was an excellent fish-catcher; its long neck was well suited to catching fish. Probably this animal was very vulnerable as it had no any protective “armor” and what is more, it had an exposed tail. It may have relied on its sight, maneuverability and camouflage colors to survive.
You can see Skeleton of Plesiosaurus being in the Moscow Paleontologic Museum on this 3D photo. Plesiosaurus was first found by the famous fossil hunter Marry Anning in 1821 in England. Since that time the remains of Plesiosaurus have been found in all parts of the world.
