Re: black and white Archaeopteryx



Melanin pigment may have a structural role rather than one relating to colour 
pattern.  It has been suggested that the dark tips on the wings of many 
otherwise white birds (e.g. many gulls) serve to strengthen the feather tips 
and resist wear.  Even if Archaeopteryx was not an active flyer a similar 
explanation might have been involved (e.g. protecting feather tips against 
abrasion through contact with vegetation, etc.).

Darn, paywall.

But the artist's illustration raises a question, what sort of
environment would this patterning be best suited for, assuming
it wasn't for display purposes? I'm thinking, lots of shifting
patterns as leafy branches sway in winds...
