Spinosaurus

Spinosaurus was a ferocious fisher-catcher who spent a lot of time in the water diving to catch big fishes. It lived from 112 to 93.5 million years ago. This giant was discovered by the paleontologist Richard Markgraf, but only in 1915 the scientist Ernst Stromer would describe it as a new specie. Spinosaurs' name means spine lizard. It is separated in only one specie: Spinosaurs aegyptiacus which means egyptian spine lizard. Spinosaurus belongs to the spinosauridae family. We believe that Spinosaurus fed with fishes.

The strangest thing about Spinosaurus is his spine which reached 2 meters. Maybe he used them for termoregulation or attracting female Spinosaurus. It wasn't one of the heaviest meat-eaters but probably one of the longest. Its length was about 12 meters and 18 meters (maximal size we know today) and an average size about 15 meters. It weighted about 10 000 kilos! This huge size needed a lot of energy. Spinosaurus' mouth was like a crocodiles' mouth and had a lot of teeth that made a perfect cage for his unfortunate preys. His massive claws served to catch better the fish so it couldn't go away. We must thank for their extinction, because it would be terrifying to see him.
