Spinosaurus, the "Spine Lizard," is the subject of a heated debate in the scientific community. One thing that is not debated, though, is the sheer size of the monstrosity - with a length of over fifteen meters and a sail height of over one and a half meters, Spinosaurus was quite possibly the biggest terrestrial carnivore to ever live. Prior to 2014, Spinosaurus was thought to have a fairly normal theropod body, with its body resting on top of long legs. However, a 2014 study claimed that Spinosaurus had short hind legs and walked on all fours. This quadrupedal model set the paleontology world reeling. While some people accept this model, most are not ready to accept such a drastic revision based on the fossils and simply reconstruct it with shorter legs and a longer torso. Despite the controversy over its anatomy, there is still much that scientists agree on. Spinosaurus lived during the Cretaceous Period in what is now Northern Africa. Its environment was very wet, and it spent a great deal of time in the water. A proficient hunter, Spinosaurus posed a huge threat to every creature that dared to near it. Its dangerous jaws, over a meter long, could handle all manners of prey. It also was likely very opportunistic, never passing up the chance for an easy catch or scavenged carcass.
