Who says all _Pterosauria_ were piscivores? Okay, the majority of known
forms seem to be, but this could easily be due to preservational bias. Who
is more likely to be preserved, a pterosaur hunting other pterosaurs in
the forest, or a pterosaur who spends most of his life near water, where
deposits are formed?

OTOH, I can't think of a good candidate, and you're right about the lack
of bat-eating bats.... (isn't he?)
