Re: Ptero fuzz distribution?
It has never been demonstrated that these are not post-mortem disattached
actinofibrils or other structures. There is presently no evidence that I am
aware of that indicates that they are hair-like structures (structures with
function similar to that of hair, whatever their actual makeup).

*Sordes*, *Jeholopterus*, and Lü's ctenochasmatid, *Beipiaopterus*, all
wing membranes with what appear to be fine, short, repeating hairs that
the membranes. These membranes being structurally different than bats'
not force comparisons to the ways bat wings work or operate, though bat
also do have hairs on them.
