Heaven forfend that the genus _Tyrannosaurus_ be sunk - say as a
junior synonym of _Manospondylus_. (Of course, this will probably never
AFAIK the ICZN has conserved *T.* over *M.*.
Many fossil shark phylogenies tend to be intuitive, and rely on
'trends' in tooth morphology identified by an individual researcher.
If this is still true, I'd try to make a cladogram sometime. While it can't
invent any new characters, it can at least draw a defensible conclusion from
the few known ones. Allotheria has been destroyed this way (though not
everyone seems to have _noticed_ it...).
We also have bones from the victims of _C. megalodon_, such as
cetotheriids preserved with deep gashes in their bones.
