Spinosaurus (Theropoda, Carnosauria, Spinosauridae) is a genus of carnivorous dinosaur, whose name means "spiny reptile." The genus includes two species: S. aegyptiacus, described in 1915 by Stromer and S. maroccanus, described by Russell in 1996. They lived during the early Cretaceous (Cenomanian), around 98 to 95 million years ago.
Up to 15 meters long, it is currently considered the largest carnivorous dinosaur has been discovered so far, in the same area of North Africa, Morocco, Egypt and Niger, where they found the vegetarian duck-billed dinosaurs: the Ouranosaurus, an Iguanodontidae which, like the S., curiously was also equipped to sail back. From the functional analysis of the remains is believed that the S. walking on two legs, leaving the front legs free to grab prey. When he ran, he used a tapered tail to balance. The shape of the skull, even closer than that of large predatory dinosaurs such as Tyrannosaurus and Giganotosaurus, did not prevent the animal to have a bite powerful enough to actively hunt other dinosaurs. The structure of the teeth were conical, and they allowed the dinosaur only to immobilize their prey, like the crocodiles grabbing her and shaking her head violently up to break her neck.
His teeth were conical and straight, not bent back and serrated like a Carnosaur. This led to believe at first that the S. was a large predatory fish and other river animals such as crocodiles, although probably not disdain to feed on carcasses or injured animals. Today, however, it is believed that he could also hunt other dinosaurs medium size. Although the bite of S. was not one of the most powerful, whereas the other large Theropods, however, could exert a pressure higher than that of existing large crocodiles, or about 1.2 / 1.8 tons per square centimeter, more than enough to make it active hunters of other dinosaurs . It is now believed that the S. should be as a skilled "fisher" as a hunter, both active and scavengers of prey, such as Ouranosaurus, or young Sauropods.
Contrary to what is the inhospitable desert environment where the fossils od S. are found today, this region, during the Cretaceous, when the S. inhabited the muddy banks of rivers, was a large swampy tropical paradise full of life.
S. appears for the first time in the third film in the series of Jurassic Park, also waging a battle with the T-Rex, against whom he won by breaking the neck.
