re: pterosaur wings and refs

Jim, you are correct. I do mean inboard. I wasn't considering outboard
where the actinofibrils spread like a Japanese fan from full extension
to near invisibility when the wing is folded.

Oh yes, they will permit it outboard of the elbow.  Provision for chord
variation appears to be one of their critical functions, as an
anti-flutter, anti-bistable device.  It may not be happening in quite
the way you anticipate.  Inboard of and near the elbow, I don't think
they permit it to any great extent.

All be best,
