It seems to me, racking my brain to remember bird carcasses I have
found, that the wing and tail feathers are the last to go in
decomposition. I don't know if Archaeopteryx was buried soon after death
or found a more roundabout way to the ocean, but the birds I recall retain
their tail and wing feathers long after the body feathers are falling off,
for whatever reason. I'm curious about whether any scale imprints have
been found in the Solnholfen, however. If the preservational conditions
are that good, have any scale impressions been found on Compsognathus or

This would mean that either Archaeopteryx lost its
contour feathers, or that Confuciusornis developed them separately from
