Of the largest living animals, ichthyosaurs are not far from the record. The population of the Earth about 200 million years ago, their length often exceeded 20 meters. Today, the largest tooth of one of these marine reptiles has been discovered by ancient researchers in the Swiss Alps.
They are one of the largest living creatures in history, measuring more than 20 meters in length. . Ichthyosaurs, integrated Appeared to follow More than 95% of it was destroyed The ocean about 250 million years ago. The species was diversified over millions of years as it lasted until the Cretaceous.
Three of them have just been revealed , Which will be one of the largest specimens of the breed. Discovered in the Coshen system in the Swiss Alps between 1976 and 1990 Published in the magazine .

Those with teeth may have eaten smaller ichthyosaurs and larger fish. “The first author of the study was B.S. Martin Sander suggested.
The ichthyosaurs weigh about 80 tons and are populated The oldest giant ocean formed 4 billion years ago . The Swiss Alps were then only a vast body of water, with many years of conflict Europe and Africa died and became the chain of the Alps. This is why these sea fossils were found at an altitude of 2,800 meters, in the center of the mountains!
