The '''Tyrannosaurus rex''', or T-rex, was a large carnivorous [[dinosaur]] with very small forelimbs, large hind legs and a long tail. It is one of the largest land carnivores to have ever walked the earth, measuring about 13 meters long and 5 meters high.<ref>Brochu, C.R. 2003.

[[Theory of evolution|Evolutionary]] scientists believe that the T-rex lived at the end of the [[Cretaceous]] period, approximately 65 million years ago.

However, [[Young Earth Creationism|Young Earth Creationists]] believe that they became extinct sometime since the [[Great Flood]], which was approximately 4,500 years ago.

[[Young Earth Creationism|Young Earth Creationists]] believe that T-Rex lived at the same time as humans until it went extinct.  Young earth creationists believe that the Tyrannosaurus, along with all other carnivores, was herbivorous in the [[Garden of Eden]] before the Fall, but afterwards a change occurred that caused T-rex to be unable to digest plants and therefore had to kill and eat other creatures for food.

T-rex had forward-facing eyes, which gave it binocular vision. [[Vision|Binocular vision]] is usually present in carnivores, as it helps them see their prey from far off, therefore it is very likely that Tyrannosaurus was a carnivore.

Some have suggested that T-rex was exclusively a scavenger. This may be partially true, since most carnivores today will happily scavenge available meat. However, it probably was not an ''exclusive'' scavenger, as most meat-eaters must also hunt in order to survive. T-rex's jaws were also quite adaptive to grabbing live prey, and probably used them in the same way most carnivores do: bit the throat to either crush the larynx and thus kill by suffocation or through blood loss. Also, the T-rex's large body probably required a great amount of food and therefore scavenging probably wouldn't be sufficient to support its high metabolism.<ref>http://findarticles.com/p/articles/mi_qa3790/is_200103/ai_n8932547|</ref>
