Re: Just following the trend of questioning...
Protarchaeopteryx has digit III preserved crossing under
digit II, so it would presumedly also have this morphology.
Caudipteryx only has two short phalanges on digit III, but
Gishlick (2001) notes its third digit also underlies its
primary feathers. I'm unaware of any other taxa preserved
with digit III crossing digit II, but this is only seen some
specimens of Confuciusornis, so this does not mean much.
Is it present in other deinonychosaurs aside from Deinonychus and
Velociraptor? Other birds?
