 If you're using phylogenetic taxonomy, then you should use _Therizinosauria_,
 since Segnosauria has never been explicitly defined. Synonymy cannot be 
shown.
 If PhyloCode overturns this, fine. Until then.... >>

Segnosauria was defined by listing its contents way back in the early 1980s 
(was it Barsbold's 1983 dissertation? I think so). This is good enough to 
establish the name. ICZN does not rule on taxa above family level, so it will 
be usage that ultimately determines whether or not Segnosauria is accepted. 
Therizinosauria is a latecomer name and I prefer Segnosauria, having used it 
with some frequency for the past 20-odd years.
