Tyrannosaurus rex

The most ferocious and insatiable carnivore ever to step on the face of the planet."

Tyrannosaurus, also known as T-Rex or Tyrannosaurus Rex was a species of carnivorous dinosaur.

Traits
Massive carnivores, the Tyrannosaurus roamed the land looking for prey, which they could kill with a single bone-crushing bite, though catching prey was more an issue of stealth than of speed, for Tyrannosaurus was not the fastest runner. Equipped with a head full of bone-crushing dagger-like teeth, strong hind legs, two small forearms with two fingers each and a long, thick tail for counterbalance, the Tyrannosaurus filled the role of dominant predator among many dinosaurs. Like other dinosaurs, Tyrannosaurus were egg-layers. Tyrannosaurus rex is arguably the most famous dinosaur of them all. Tyrannosaurus was the last and largest of the Tyrannosaurs.[1]Commonly known as "T. rex", this species lived during the Late Cretaceous Period in modern day North America and was therefore among one of the last dinosaurs.

Like other tyrannosaurids, Tyrannosaurus had very short arms with only two fingers. Despite the limbs' size, each were able to bench-press about 400 pounds. Although these were probably nearly useless while hunting, its jaws were not: Tyrannosaurus has an enormous skull armed with teeth the size of bananas. Unlike the teeth of most theropods, the teeth of tyrannosaurids are very thick and capable of crushing bones and with a bite force of a minimum 4 tons of force and probably more, crushing bone, ripping flesh, and bursting blood vessels of the victim. The skull and neck bones show that T. rex had the largest neck muscles of any meat-eating dinosaur. It probably used its strong neck to twist and pull off big chunks of meat that it grasped with its jaws while supporting the huge head. Tyrannosaurus could bite with extremely strong force - one fossilized skeleton shows that it crushed and swallowed the bones of a smaller plant-eating dinosaur while another shows a Tyrannosaurus coporilite with the crushed frill of a Triceratops.[1]

In popular culture, Tyrannosaurus has an iconic status shared by few other species, helped in no small part by the prominent role of the T. rex in all four films in the Jurassic Park franchise. It is the secondary antagonist turned anti-hero in the first movie, a role it retains in all movies.

History
Among the dinosaurs that went extinct during the cataclysms that struck the earth was Tyrannosaurus. A number of the Tyrannosaurus, however, had successfully found refuge in vast underground caves in which dinosaurs of all kinds had successfully survived.
