I prefer _Jenghizkhan bataar_; others still have their doubts. To me there's
a medium-size Mongolian tyrannosaurid (_Tarbosaurus efremovi_), a smallish
Mongolian tyrannosaurid (_Maleevosaurus novojilovi_), and a giant Mongolian
tyrannosaurid (_Jenghizkhan bataar_). All three seem to me to be more closely
related to one another than any is to the North American forms (e.g.,
_Albertosaurus_, _Gorgosaurus_, or _Tyrannosaurus_), and they constitute a
distinct tribe (Tarbosaurini). One could put them all in the same genus
(_Tarbosaurus_ woud have priority) as three distinct species, but it's
nomenclaturally more convenient to keep them generically separate.
