According the Currie, in most theropods, a really high collateral
pit ("high" in terms of being more dorsally situation on the lateral
and medial flank(s) of the ginglymoid) is indicative of a penultimate
phalanx (the phalanx articulating with the ungual).  I don't have
the ref. around at present, but it *may* have been in his CJES
paper on _Sinraptor dongi_ or one of the other papers in that
Sino-Canadian dino-compendium.
