The wings of Archaeopteryx just made the news again in a big way with the publication of a paper in Current Biology. It is – bah! – sadly not freely available here. The authors show that the wings of feathered dinos were structured fundamentally differently from those of modern birds, with several layers of feathers instead of just one forming the airfoil. That may have given greater stability than the weak feather shafts suggest, but made the airfoil less capable. Go read the paper!
But before you do, let’s take a good look at the original first Archaeopteryx specimen:
Yes, that was the first ever find – and don’t get me started on the validity of the assumption that this feather came from the same species as the body fossils….
And this fossil makes the MfN the only museum – to my knowledge – that holds TWO specimens of Archaeopteryx.
