  Therizinosauria was coined in 1997 by Maryanska (as I recall, no one
could find an earlier occurence of this name ... it is listed as "implied"
by Maleev on the Dinosauricon, a function of taxonomy no longer favorable
when cladistics is applied). It was never cladistically defined by her.
Meanwhile, a clade name with the same content was proposed back in 1980,
Segnosauria. By content and origin, it is the "proper" name.
Appropriateness of the use of a single taxon in all segnosaur suprageneric
taxa as specifier is a bad reason to favor one name over another when
clear precedence is available.

  Little steps are often the hardest to take.  We are too used to making leaps 
in the face of adversity, that a simple skip is so hard to do.  We should all 
learn to walk soft, walk small, see the world around us rather than zoom by it.
