Pterosaur hand and wrist musculature

[John Conway <john.a.conway@gmail.com>]

What do people think happened to the tranversus palmaris and flexor 
digiti quinti in pterosaurs (presuming digit V is lost, and not the wing 
finger)? Also, presuming the pteroid is a neomorph -- not digit I or 
metacarpal I -- what muscles were available to control it?

Any refs on this would also be appreciated (better yet, PDFs, as I lack 
university access at present).

P.S. Feel free to ramble on about pterosaur digit identification.
