Actually, the body covering of this specimen does not look that different
from many of the _Confuciusornis_ specimens I've seen. I strongly suspect
that the difference between "protofeather" and true contour and/or wing
feather structure has far more to do with differential preservation than it
does with the original details of the plumage.
