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. Osteology of Tyrannosaurus rex: insights from a nearly complete skeleton and high-resolution computed tomographic analysis of the skull. Memoirs of the Society of Vertebrate Paleontology. 7: 1-138.</ref> Most mainstream [[Theory of evolution|Evolutionary]] scientists believe that the T-rex lived at the end of the [[Cretaceous]] period, approximately 65 million years ago. [[Young Earth Creationism|Young Earth Creationists]] on the other hand believe that they became extinct some 6-5,000 years ago, after [[Great Flood|Noah's Flood]] when the environment became too hostile for them, however, this view is supported by very little scientific evidence, and is generally regarded with much skepticism outside of the young earth creationist community
