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.
Kurochkin thinks "sauriurines" (Archaeopteryx, Jibeinia, confuciusornithids,
enantiornithines, Patagopteryx) evolved from theropods, but ornithurines did
not. A ludicrous notion if there ever was one.
