[[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 sometime since the [[Great Flood|Noah's Flood]], which was approximately 4,500 years ago.
