Re: Pterorhynchus dewlap
It's only a single annecdotal peice of data, but the one time I saw a
lionfish in the wild it was drifting around in the current and looked
like nothing so much as a broken-off tuft of coralline aglae (such as
might make a lovely shelter for a small fish.....)
I have no idea if this is a typical behaviour for them, or if my
interpretation in any way resembles what was going on.

Ah! You obviously haven't read Klaus Ebel's work...
Ebel, K. (1996). On the origin of flight in _Archaeopteryx_ and in
pterosaurs. N. Jb. Geol. Paläont. Abh. 202: 269-285.
He argues that many pterosaurs spent their entire lives underwater.
Then again, Ebel also argues that all saurischian dinosaurs lived in
water - sauropods, tyrannosaurs, dromaeosaurs, the entire shebang.
Ebel's work aside (it's been discussed before on the list, as far as I
recall), I wonder if any pterosaurs could submerge (partially or
completely) for brief periods?
