Who are the ichthyosaurs?

In the Triassic true masters of the seas became the sea lizards. Best of all for life in the water were adapted ichthyosaurs, which is very reminiscent of modern dolphins. They were Nastavenie limbs that could quickly and nimbly to move in the water. In addition to last, they have developed fins, but not radial, as in fish, and in skin folds. Ichthyosaurs ate fish and were viviparous animals. A newborn baby was immediately sail for the mother in the pack, which was concerned about its security.
