  Yet Mickey has repeatedly argued that the figure in Naish, Martill and
Barker (2001) implies a cladistic definition of {Oviraptorosauria +
Segnosauria}. What, if anything, is the implied usage of "Enigmosauria"
sensu Mortimer, to apply *Protarchaeopteryx* in relation to? Is it a stem,
node, apomorphy-defined clade name?

  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.
