Note that many basal ornithuromorphs have short ulnae, which is not surprising 
given Cau's analysis that found Parahongshanornis isn't a hongshanornithid-

think people would learn not to attach their untested phylogenetic hypotheses 
to names.  Paraprotopteryx, Parascaniornis, Protarchaeopteryx...
