Re: Pterosaur Fur

If pterosaur wing fur/fuzz was long enough and if it

leading edge.

Unfortunately (or perhaps fortunately for pterosaurs) there is no convincing evidence for hair on pterosaur wings.

Pterosaurs had numerous ways of controlling their flight membranes, including -- but probably not limited to -- twist at the shoulder and the base of metacarpal IV, sweep of the wing finger, various possible motions of the pteroid, muscles intrinsic to the flight membrane, and possibly air sac inflation and hind limb movements.
