Since _Tarbosaurus efremovi_ is the type species of _Tarbosaurus_, sinking
it into _T. bataar_ would sink the genus _Tarbosaurus_ along with it,
No, it just makes _T. bataar_ the (subjective) type species of
_T. bataar_ was made the type species of _Jenghizkhan_, so I would think
if you wanted to synonymize the two Asian species *and* put them in a
separate genus from the North American species, you'd have _Jenghizkhan
bataar_ and _Tyrannosaurus rex_.
Or have I gotten the rules wrong?
The latter. With one Asian species not in _Tyrannosaurus_, you get
_Tarbosaurus_ as the oldest available genus name.
