Spinosaurus is the largest carnivorous dinosaur in the days just as T-rex (Tyrannosaurus). but Spinosaurus has a history that is more terrible than the T-rex is an extra long snout like a crocodile, and have arms capable of gripping prey, not bleak T-rex who only uses her mouth.Scientists say that a fossil dinosaur bones from the neck-faced crocodile found in Australia, this suggests that the spread of these animals was beyond all conjecture.Dinosaur called Spinosaurus was found in the southern city of Victoria. "Dinosaurs are small enough compared to other types of Spinosaurus. Being of life is approximately 105 million years ago," says researcher Thomas Rich.Spinosaurus is characterized by a long mouth like a crocodile, known formerly lived in Europe, South America and South Africa, "Rich.Rich explained that this is the first time Spinosaurus fossils are found on the continent of Australia."The fact that these dinosaurs lived on the continent of Australia to change our understanding of the evolution of this group of dinosaurs, says Rich, who is also the curator of the Museum Victoria.Rich will research journal, said the findings also support the opinion that the animals in Australia is different from other animals on the continent in the early era of Crete.Spinosaurus famous among fans of dinosaur because it has sailed back and elongated skull, it is mostly known from fossil remains that have been destroyed. In addition to tooth recently found a little of the skull.
Moreover, so far only the skull and backbone have been described in detail, and the limb bones have not yet described by scientists. Some of the speculation going on in the argument between scientists and paleontologists that Spinosaurus aegyptiacus might walk using four legs, but most people do not believe this.Jaw and skull Spinosaurus was first published in 2005, stating that it was one of the longest skulls of any carnivorous dinosaur, which is along the 1.75 meter (5.75 feet). The skull has a narrow snout filled with straight conical teeth that do not have serrations. There are six or seven teeth on each side, the front part of the maxilla, the premaxilla bones, and twelve in both maxillae behind them. The second and third teeth on each side that feels bigger than the rest of the teeth in the premaxilla, creating a space between their teeth and large teeth in the upper jaw.The tip of the snout Spinosaurus contains more large anterior teeth, and there is a small canines in front of the sail of Spinosaurus mata.Punggung formed due to the very high neural spines growing on the spine. Dorsal is between 7-11 times the height of their spine. Spines are slightly longer from front to back.
