The earliest find of a ''Tyrannosaurus rex'' occurred in 1892. In 1905, after additional discoveries of fossils, the president of the American Museum for Natural History named the dinosaur. Since then, more than 30 specimens have been found.

In 1990, amateur paleontologist Susan Hendrickson discovered the most complete ''Tyrannosaurus'' fossil yet. The fossil, named "Sue", is also one of the largest ''Tyrannosaurus'' specimens discovered.<ref>Guinness World Records Ltd. (2003). 2003 Guinness World Records. pg 90.</ref>

Paleontologist Mary Schweitzer has discovered unfossilized soft tissue in T-rex skeletons. This was unexpected as tissue was not known to stay unfossilized for 65 million years. Evolutionists saw this as evidence that tissue can last that long, whilst creationists saw it as evidence that the fossils were not that old.<ref>[http://www.creationontheweb.com/content/view/3042 Still soft and stretchy], by Carl Wieland.</ref><ref>[http://news.nationalgeographic.com/news/2005/03/0324_050324_trexsofttissue.html National Geographic - T.

Scientists determined that the T-rex lived at the end of the [[Cretaceous]] period, dated to approximately 65 million years ago, and that modern birds are the descendants of dinosaurs such as T-rex. <ref>[http://www.cnn.com/2007/TECH/science/04/12/dinosaur.reut/index.html Bird Family Ties]</ref><ref>http://www.livescience.com/animalworld/ap_trex_tissues.html T Rex Tissue</ref>
