Today, scientists are divided on whether Tarbosaurus is a genus of its own or whether it should be classified as Tyrannosaurus. A close examination of the fossils shows that it was very closely related to Tyrannosaurus rex, so closely that it could actually be a subspecies of T. rex. The name Tyrannosaurus bataar has been suggested, and indeed some textbooks have begun to use this name and drop Tarbosaurus.
