Spinosaurus `thorn lizard` is a genus of theropod dinosaur that lived in what is now North Africa during the late Lower and early Upper Cretaceous.Spinosaurus shows conspicuous spinous processes of the vertebrae, which were at least 1.69 meters long and were probably connected with skin to form a sail-like structure. Some authors also suggest that they were surrounded by muscles and formed an elongated hump. The function of this structure remains unclear - among other things, functions for thermoregulation and communication with conspecifics, e.g. B. Discussed the impressive behavior.Numerous features indicate a semi-aquatic way of life. This includes the small pelvis. The feet resembled those of today`s waders. They may also be webbed. The long neck and the relatively long trunk move the body`s center of gravity forward. Although Spinosaurus ’hind legs were not particularly long, they were sufficient to enable a bipedal two-legged walk on land. Most likely Spinosaurus hunted fish like Onchopristis, a large representative of the pseudo-sawfish, especially in shallow water.
