Re: oviraptorosaur pelvis in dorsal view

  All I can provide is the paper describing the non-caenagnathoid
oviraptorosaur *Nomingia gobiensis*.

Barsbold R.; Osmólska, H.; Watabe; Currie, P.J.; & Tsogtbaatar K. 2000. A
new oviraptorosaur (Dinosauria, Theropoda) from Mongolia: The first
dinosaur with a pygostyle. _Acta Palaeontologica Polonica_ 45 (2): 97-106.

  This pelvis is different than oviraptorid pelvises, and it is apparent
from sacra in caenagnathids that *Nomingia*'s pelvis is apomorphically
narrow, and that the ilia contact the sacral neural lamina (fused neural
spines). Need a complete sacro-iliac complex in dorsal view to be
described, but this is present in GI 100/42 (oviraptorid) and Triebold's
new form, and is undescribed in the literature.

  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.
