Evolution - a serious thing.At each stage of the formation of our planet in a certain period of time there were certain animals which, of course, are the elite of his era.Those long considered the prehistoric predators.We talk about them.
vertebrates inhabit the Earth for over 500 million years!Almost half of this period, the planet was dominated by the prehistoric predators - dinosaurs!You just think about those numbers!No other group of animals could not survive in the history of the formation of the Earth for as long as it has turned the ancient dinosaurs.They were the real lords!
Prehistoric Predators - the crown of creation of nature!
At one time, the ancient reptiles is the pinnacle of all terrestrial organisms that inhabit our planet.Dinosaurs were the lords of the land over 100 million years!They were numerous and various monsters.No other creature could not match them in strength and perfection!Today prehistoric predators, reptiles never cease to haunt the minds of scientists and narrow-minded: the process of their existence and the drama of extinction are human interest from the moment he learned of the Great Age of Reptiles!Dinosaurs are studying very carefully, no other type of extinct animals do not use in the scientific community as more popular than ancient reptiles!
Prehistoric marine predators
Over time, land has become too crowded, and some reptiles began to explore the water.Scientists have traced experimentally that reptiles throughout the history of its development from time to time returned to the water.This happened when there they waited for more abundant food and livelihood security.For them it is there is no difficulty, because life in the seas and oceans not require reptiles absolutely no major rearrangements in the body and physiology.
The earliest prehistoric predators, mastered the water were anapsid - Mesosaur Permian.Behind them in the water gone primitive Diapsid - tangozavry, talattozavry, klaudiozavry and hovazavrusy.The most recent group of aquatic reptiles ichthyosaurs became famous.These marine predators were simply superb adapted to life in all the waters of our planet.The shape of ichthyosaurs very much resembled the most common fish or dolphins: triangular head with long jaws, outstretched body, flattened on the sides, the blade of tail fin - the vertical and legs transformed into four ventral fin.
Lord of the seas and oceans The largest ever living in the water reptile was one liopleurodon.All other marine prehistoric predators simply faded in front of him ... its lifetime fell to the Jurassic period.About the size of this gigantic creatures still walk academic debate.Four huge fins, short and laterally compressed tail, as well as a very large and narrow head with huge teeth (about 30 cm in length) made him the undisputed ruler of the ancient seas and oceans of the planet!
