"'Feathers' refers to hollow-based, filamentous, epidermal appendages 
produced by follicles."  Those hairy pterosaurs may throw a spanner in the
works.  Not to mention the tail of that psittacosaur specimen.  (And do the
'parafeathers' of _Longisquama_ count? ;-)  )

Nor I.  I'm still confused.

Don't know about Panaves.  But Ornithes has been published elsewhere, and
the priority is pretty impressive: Aristophanes c.414 BC.
