Re: Longipteryx chaoyangensis (Aves, Enantiornithes?)




This whole discussion about fuzz vs feathers may be premature as long as
none of us have seen the actual specimens. Liaoning fossils often don't
photograph very well, and this is specially true of imprints of soft
parts. As those of You that have seen NGMC 91 "in the flesh" knows there
are a great deal more imprints there than are visible in the
photographs, much of them unpigmented, particularly in the distal parts.

Note that in the illustration in the paper Zhang et al. indicate that
there are prints of long flight feathers in the large prepared area to
the left and below the hand of V12325 (much of this is cropped in the
photo at http://www.scichina.com/ky/0111/kyfm11.stm) and that the taxon
is also based on paratypes not illustrated including a complete skeleton
(V 12552).
