I agree with you but, to me, a good sediment were are preserved the
fossil feathers is in micrite limestone (calcareous-argillaceous
deposit)-(of course, amber is better)- like Las Hoyas (Cuenca,Spain) and
Montsec (Lleida, Spain) as well as a bottom anoxic and others
conditions. At present, in Montsec outcrop, we found about
20-23,remarkable specimens of isolated feathers in carbonous impressions
with punctuate deposits of pigment in its barbules which allowed a
correct identification and diagnose.
