Once again: this was not my wording; I quoted it merely to show that not
everyone accepts pterosaur hair.

I think the reference was to fibers ON the wings but closer to the base of
the wing (ie the body) than the longer fibers.

I have heard this explained as an artifact of post-mortem conditions, with
the stiffened fibers emerging from a partially decayed or damaged wing
membrane as the wing dried or shrunk. Again, please note that these are NOT
my opinions; not having examined the specimens personally I don't really
feel comfortable having any on this point.
I would think that hair would be more
