RE: terminology

  It seems odd that after I mention that the ICZN can be used to set aside 
*Manospondylus*/*giga* for *Tyrannosaurus*/*rex*, that this is being said to 
_me_. The issue is whether this is neccessary. It is not: No one uses the 
former, nor pretends the former has any sort of utility over the latter.
