Deinonychus pubis

[sherry@spatula-net.com (Sherry Michael)]

I was reading parts of a borrowed publication- it was "osteology of
Deinonychus antirrhopus" Peabody Bulletin 30 by Ostrom.  Anyway, I was
surprised to read the description of the pubis. It was described as a flat
bladelike bone, without a shaft at all. However all the mounts and
descriptions I've seen, Deinonychus has the typical theropod "shaft and
boot" pubis.  What' s the story?
