Black Feather Colour in Archaeopteryx
As reported in New Scientist:
[Ryan] Carney and colleagues used scanning electron microscopy and
energy-dispersive X-ray
analyses to detect the melanosomes [of an Archaeopteryx feather], then compared
this data to
similar feathers in a database of 87 modern bird species. The feather, he says,
was most probably
black. While the full colour pattern of Archaeopteryx has yet to be uncovered,
Carney noted that
melanosomes on the black feather have structural properties which may have
strengthened the
feathers for the demands of flight. The miniscule structures which hide the
secrets of prehistoric
colour were not just for show.
