Re: Pterosaur Fur

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

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.
