Re: Wilkinson's new pterosaur paper, J. Headden
The actinofibrils are intercalated. They do not run full length. They can
be longitudinally lengthened (and shortened) by shifting relative to one
another along their lengths. This is one of the primary mechanisms for
controlling the aeroelastic number and inhibiting flutter. It can also be
used for roll control.

Fibers beyond the elbow can be rotated to show their maximum chord
length. They cannot be longitudinally lengthened as I demonstrated with
the Zittel wing (ref. Peters, D. 2002b. A New Model for the Evolution
of the Pterosaur Wing – with a twist. - Historical Biology 15: 277–301).
