Pliosaurus Vs Plesiosaurus.

Pliosaurus and Plesiosaurus are two distinct genera of the same family or order of marine reptiles that lived in prehistoric times. Now there are few giant marine reptiles, arguably the most important the marine crocodile with more than 6 feet long, but that was nothing compared with the members of these two genres that were true sea monsters. Here are some.

Pliosaurus.

They were usually large predators with large jaws and well armed, short necks. Some examples are:

Kronosaurus A marine reptile which, like other Pliosaurus, had short necks but strong. Their jaws measured 2.5 meters long fang-filled and the length of his body could be up to 12 feet and weigh 15 tons. Some call it the Rex Marine.







Liopleurodon was another Pliosaurus but with their own families, the Liopleurodon was a great swimmer, a lively marine predator,
with a shape similar to but even larger Kronosaurus. Grow to 27 meters and weigh 150 tons, was able to pursue quickly and for long periods at their prey. With jaws 3 meters long and with teeth to tear to twice as long as those of a Tyrannosaurus Rex. (30 cm long)


PREDATOR X. A curious name for
an animal surprising. It is believed that X was a Liopleurodon Predator, a large skull and huge jaws, its dimensions were similar, maybe a little smaller: a 3-meter jaw full of teeth over 30 cm long and it is
believed, was an animal that had more bite force among all known.











Plesiosaurus.

Large predator fish from four large fins and long necks characteristic of animal facilitated its kind that raises its head to breathe. The best known are:




Elasmosaurus. About 15 meters long, which were 8 meters long neck and the rest is for your body. With a weight of 9 tons, was a heavyweight of the oceans of the Cretaceous. And although it was stylized and rather graceful, was a super-predator of the time. Although he was no match with any of the three Pliosaurus we've seen (like the Predator X Kronosaurus or who were his rivals and could live at the time)





NOTHOSAURUS. Another known Plesiosaurus, possibly one of the first of its kind. Not exactly a Plesiosaurus, but was (or any of its branch) who gave birth to this genre. It was "little" about 4 meters long and less than a ton. With strong long teeth that bite and to catch fish served with a quick bite.



CRYPTOCLIDUS. Possibly the second most popular after Elasmosaurus Plesiosaurus. Was over 8 meters long and weighed 8 tons. His neck, long as all Plesiosaurus was more robust than others, however its elasticity was lower. This being a predator rather Bland. Hunted large prey and not be satisfied with simple and small dams. However, it was an animal whose size had very few enemies.


Now, after the abstract, let's see some videos:






Nothosaurus



Nothosaurus is an extinct genus of sauropsids (reptiles) Triassic marine, was among the first plesiosaurus (like the famous Elasmosaurus). Its name means "fake lizard" and who were not lizards like today's or even a dinosaur.
His teeth, very sharp as daggers, which also fit together those in both jaws, was a perfect trap for fish. Nothosaurus could close the mouth with great force but the muscles that allowed him to reopen it were very weak. Some of the best preserved fossils preserve the skin and drawing show that Nothosaurus had webbed feet, suitable for both the aquatic environment and to the land.
They could spend part of their life on land, on the sand and rocks. The tips allowed them to walk and move awkwardly arched his back, like lions today. You probably arrived on shore to stretch out, relax and warm in the sun, capturing prey on the pools of the shore and to reproduce by laying eggs. Breathed air, as shown by the two nostrils at the top of his nose, and although it was undoubtedly a stylish swimmer, was not so well adapted to an aquatic lifestyle as full-time as Opthalmosaurus ichthyosaurs.
