He used that line!  Great!!

No sad face needed.  This is proper taxonomy.  Currie does not consider this
Mongolian species congeneric with _Tyrannosaurus rex_, and he considers it
all one species.  Therefore, the proper name for this taxon uses the oldest
valid trivial nomen (_bataar_) and the oldest valid generic name
(_Tarbosaurus_): hence, _Tarbosaurus bataar_.

I think you may want to have a second thought about that laugh, though,
without considering the aspects of intraspecific variability and questions
about accuracy of illustrations...  Indeed, there may be a lot fewer
ornithomimosaur species and genera currently represented in collections than
represented on websites and published taxon lists.
