Re: Pterosaur Fur

Even if the wings had hair (unlikely, as has been

pterosaur wings could change shape in a number of
ways, though I do agree that it is not immediately
obvious/intuitive when looking at them for the first

There is one way that the fuzz/hair on pterosaurs
could be aerodynamically useful, however, and that
is in the production of a turbulent boundary layer.

I've seen a lot of pictures of bats but do not recall seeing any hairy wings. Are there any hairy winged bats? If so, there'd at be something to compare with.
