Oops.  How did I let that one slip past?  Stupid Chirostenotes in the
Caenagnathidae confusing matters.....grumble...

I was speaking of articular-surangular fusion, which is present in
Chirostenotes, Avimimus and ornithothoracines, but absent in oviraptorids
(Osmoslka 1976, Barsbold et al. 1990, Smith 1992, Elzanowski 1997).

I consider these processes homologous to the mid-dorsal ischial processes of
Sinornithosaurus, Rahonavis and Archaeopteryx.  Never even noticed the one
on Nomingia.  I'll add it to my matrix...
