Just a nitpick (don't want to deviate too far from the topic),
_Dynamosaurus_ was sunk in favor of _Tyrannosaurus_ when Osborn acted
as first revisor and chose the later as the senior synonym, as
required by the ICZN when two synonymous taxa are named in the same
publication. If you meant _Manospondylus_, contrary to popular belief
no ICZN action has ever been taken or requested, nor is the name a
nomen oblitum under the current code. If _M. gigas_ is considered
synonymous with _T. rex_, the former is the correct name. See my post
on this here:
