Ancient sharks swam where nowadays sow wheat and build cities. Therefore, fossils of sharks sometimes discover for tysychi kilometers from the sea. Paleontological scientists studying ancient forms – most often find shark teeth. Fossil shark teeth affect its size. Most krupnye- length of 15 cm. And a weight of 340 g – belonged to the monster in the mouth which could put a man gets up to his full height, and it reached 13 meters in length!
After hundreds of millions of years, descendants of the ancient sharks overcome thorny path of evolution continue to surf the seas and oceans.
