When Kurochkin says "phalanx II-1", does he mean the middle digit or the
innermost digit of the tridactyl manus? Is it digit II of I-II-III from
ancestral pentadactyl condition (as dinosaur experts interpret the avian
tridactyl manus), or digit II of II-III-IV (as ornithologists prefer)?
Evgeny Kurochkin was one of the authors of the paper in *Science* that
claimed that Longisquama's plume-like appendages were feathers (or at least
ancestral homologs of bird feathers). I don't actually belive it myself. But
it may mean that Kurochkin favors a non-dinosaurian origin of birds.
