How about correlating lung + heart volume (= total thoracic volume) relative
to body mass, for various habitual activity levels among living animals, and
then compare to thoracic cavity size among dinosaurs?  This may help estimate
general aerobic capability for dinosaurs.  Is this old hat, or just too
crude a measure?
