Re: cerebellum size
I was reading Chris Brochu's (2000) paper, "A digitally-rendered
endocast for _Tyrannosaurus rex_" (JVP 20(1): 1-6).
On page one he says "More basal theropods and nontheropod dinosaurs
retained the plesiomorphic arrangement of a large cerebellum projecting
dorsally over the roof of the forebrain."
But I thought such an arrangement was also found in "derived" forms
like birds, so I am scratching my head and trying figure out why this sounds
so confusing to me. I don't think Chris is back on the list yet, and just
wondering if anyone else here knows much about cerebellum evolution.
It seems like this should be important with respect to the evolution
of flight and secondary flightlessness.
