  Not really, GI 100/25 most definitely has a furcula.

  The claw is positioned in the neck viscuous area right behind the skull.
Problematically, preservation would cause the limbs to move a little, but
this position does not seem to be severely affected as the entire couplet
of the Fighting Dinosaurs specimens are preserved very tensely, and it is
likely that they were preserved in just a matter of seconds, rather than
minutes, and the work of Loope et al has suggested that the cataclysmic
event was a "sandslide" upset by water destability in the dunes, and not a

  Searching for "sandslide" in the archives will produce references to
this effect and of Loope et al.

  Little steps are often the hardest to take.  We are too used to making leaps
