  Yes, that's the fightin' dino itself. I forget who it was who said the
furcula was actually missing from the specimen, but as I recall, the
material figured by Barsbold in 1981 and 1983 is from GI 100/25, and
satisfies Bryant and Russell's criteria for a furcula, including cresentic
cross-section (described as grooved on the back), expanded and flattened
distal rami, and a "tongue-depressor"-shaped median ventral flange
(hypocleidial process). So I really can't see how this element is not the
furcula. If I'm wrong, fine. I would like to see the reference that
indicates it is either not present, missing, or was never part of the
pectoral girdle, though.

  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.
