Re: The birds vs. the pterosaurs
Ronald,
I still haven't had time to do more research on "bird-brains",
theropod brains or pterosaur brains, but it is my understanding that it is
the cerebellum (not the cerebrum) which controls most of the "mechanics of
flight", and that the cerebellum of Archaeopteryx expands up and forward
over the rest of the brain. It seems like I once read something similar
occurs in the brains of pterosaurs (but not sure).
Maybe when Chris Brochu returns to the list, he will have something to
say about how the cerebellums (cerebella?) of theropods (especially
maniraptors) compare to those of these flighted forms.

P.S. I thought the same thing about wasps stinging dinosaurs----doesn't
sound like that fellow "thought that through" very thoroughly. Maybe he
thinks the blood pressure of the dinosaur would force the blood up the
wasp's stinger and into its body. <snicker>

There is absolutely no way to determine this, of course, although I have
never heard that their [pterosaur] brains were particularly large (though I
assume they have large optic lobes, and would certainly needed pretty good
higher brain functions to control the mechanics of flight. That certainly
isn't the same as intelligence, though.
