Bigger Bird Brains = Survival Benefit



This result leads to all sorts of interesting
speculation regarding dinosaurs, particularly those
taxa thought to have bigger brains (troodontids,
ornithomimids, etc.)

One might also speculate on the evolution of large
brains in pterosaurs.  For example, are there enough
cranial remains of azdarchoids to know whether or not
they possessed larger brains than other pterosaurs?
