RE: terminology
The current opinion is that the holotype of *Manospondylus gigas*, an eroded
pair of dorsal centra, are similar to that of *Tyrannosaurus rex*, but may also
compare well to other taxa (*Tarbosaurus bataar*) as well as *Daspletosaurus*
spp. This makes it difficult to _prove_ that *Tyrannosaurus rex* and
*Manospondylus gigas* are synonymous. The general consensus (that I am familiar
with) has been to treat the type as nondiagnostic, and the taxon as a _nomen
dubium_ (if these things had any value other than justification for not
considering them useful for competing for priority).
