Because I wasn't trying to improve Hou et al.'s analysis by adding characters or states, just trying to make the states used more accurately coded. Also because no taxa in the matrix have a propubic pelvis.
Okay. So for this situation, mesopuby is the plesiomorphic state?
I said no _Mesozoic_ avians have been described with caudal pleurocoels, some living taxa (eg. Struthio I think) have them. Microvenator doesn't have them, just Nomingia and caenagnathoids. Also found in carcharodontosaurids and perhaps a few other things.
My bad.

I don't think I meant to code it that way, but it has pretty damn reduced hands, wouldn't you say? ;-)
