Unformatted text preview: Yes & No-Scaling effect (if less surface than volume, suffer and benefit-Heat generation is related to body volume-Heat removal is related to surface-Doubling size causes overheating, half-size causes over cooling-For larger animals – easier to keep constant body temp in low ambient temperature-Easier to be overheated in high ambient temperature - gigantothermy How did dinosaurs control their body temperature?-Warm-blooded control body temperature with nasal turbinate, membrane maintains heat and moisture when we exhale. It also warms up and moistens oxygen as we breathe in. dinosaurs may have had nasal turbinate, but not truly warm blooded-Large dinosaurs may have been gigantothermic homeotherms-Small dinosaurs had feather (insulation) but no turbinate; they are partial endotherms...
