  Unlikely. Similar sediments of the same state of preservation
(ash-laden lägerstatten from around the Jehol biota and extend
of the Jehol Group) show several birds with complete remiges and
retrices, and *Confuciusornis* has both "fuzz" on it's body as
well as true feathers and unsual retrices which lack partitioned
vanes. However, I find the idea (dismissed at first, put forward
by HP's David Marjanovic and Mickey Mortimer) that the animal is
moulting is not improbable.
