Crossed my mind as well. See my Archaeopteryx page:

(may be easier just to go to http://www.wam.umd.edu/~tmkeesey - shorter URL)

I thought of it myself, but I seriously doubt I'm the first. Does anyone 
know of any research done on this idea? What *is* pterosaur "fur" anyway?
Could it be homologous to feathers? Are they both homologous to scales?
