Tyrant lizard King Etymology
Tyrannosaurus is derived from the Greek "tyrannos" (tyrant) and "sauros" (lizard).
The species epithet, rex, means "king" in Latin.
Synonyms
Manospondylus gigas (Cope, 1892)
Dynamosaurus imperiosus (Osborn, 1905)
Nanotyrannus lancensis? (Bakker, Williams and Currie, 1988)
Stygivenator molnari (Paul, 1988)

Discovery
The first "diognostic" remains of Tyrannosaurus rex, BMNH R7994 (originally AMNH 5866 and known as Dynamosaurus imperiosus) were discovered at Seven Mile Creek in Wyoming's Lance Formation by Barnum Brown in 1900 and now reside in the collections of London's Museum of Natural History. However, the actual holotype, CM 9380 (originally AMNH 973), is a partial skull and skeleton discovered by Brown two years later at "Quarry No.1" in Montana's Hell Creek Formation. It is housed at the Carnegie Museum of Natural History.
