Frank Seebacher's research on thermoregulation

Overlooked compendium of interest:

N.S.W.: Surrey Beatty & Sons), 446pp.

interactions compromise thermoregulation in

Thermoregulation is far more complex than the "media"
would have it, viz. "ecothermy" and "endothermy" are
not monolithic paradigms. Energy costs, cardiovascular
systems, etc., probably precluded some sauropods and
other megaherbivores from being endothermic, and there
is the possiblity that, for some active and gregarious
taxa, endothermy may not have been energy efficient
for maintaining basal metabolic rates. While I do not
believe crocodylomorphs are proper foci for research
on pre-K/T dinosaurs (after all, there are @9000
living dinosaur species today), data on their
thermoregulatory abilities and resistance to
dehydration in high-stress social situations might
prove useful for comparative analyses
