Nanotyrannus, a real genus or not?

Several specimens of the enigmatic tyrannosaurid dinosaur Nanotyrannus lancensis
have recently come to light. These new specimens, derived from the upper Maastrichtianaged
sediments of the Lance and Hell Creek Formations of Wyoming, South Dakota, and
Montana, along with a recently described juvenile specimen of Tarbosaurus bataar from
the Nemegt Formation of Bugin Tsav, Mongolia, provide new information that
unequivocally demonstrates that this dinosaur is unique and clearly not a juvenile
Tyrannosaurus rex, as proposed by some other researchers. Comparisons with known and
new specimens of Tyrannosaurus rex show a host of characters that support the taxon,
Nanotyrannus lancensis. These characters include: consistent substantially greater
maxillary and dentary tooth counts, unique general tooth morphology (especially for the
first maxillary and dentary tooth positions), a unique exit for the V-2 cranial nerve,
unique pneumatopores in cranial elements, a shallow (as opposed to a deep) antorbital
fossa, the presence of a long linear groove on the lateral aspect of the dentary, a
morphologically unique furcula, an outward facing scapular glenoid, a proportionally and
absolutely larger manus, the presence of third digit manus phalanges, and the presence of
an anterior iliac hook.
