PDAllosaur
Allosaurus (Marsh, 1877) was one of the largest Jurasssic predators known, growing up to 33 feet (10 meters) long. It had a large skull with eye ridges, and long, flesh-rending claws. It ate many different dinosaurs, such as the Ornithopod Dryosaurus, the stegosaurid Stegosaurus, and even young Sauropods like Diplodocus. Due to it's large size and 'new-age' design, the previous apex Jurassic predator Ceratosaurus was outcompeted and replaced, but with a difficult competition with a giant megalosaurid named Torvosaurus. Luckily however, Saurophaganax is a larger Allosaurus species in which drove Torvosaurus to extinction. One particularly well-preserved specimen, nicknamed "Big, Al", was found not too long ago in Wyoming. It had many different injuries from throughout its short, seven year life, yet surviving all but the last one, an infected toe wound. This would have left the animal unable to hunt, and it would have starved or died of thirst.

SkullEdit

下载

Allosaurus' skull was double hinged. This allowed it to open its mouth extremely wide, allowing it to have a huge bite radius. One hinge was near the front of the jaw like a snake's, and the other was near the back of the jawbone. However, recent studies seem to show that Allosaurus had a relatively low bite force, even less than the value of sharks and crocodiles, despite being much bigger. It seems that Allosaurus attacked using it's head like an axe, using its double-hinged jaw to open really wide and dropping the top part of its skull into its prey with a large amount of pressure while holding it steady with its strong arms. A constant repetition of this method would have led to a massive amount of blood loss and shock. It was a very efficient way of killing, and it's probably why Allosaurus was so successful as a hunter.
