Abstract
This study focused on known sites of physiological heat exchange, where moist, highly vascular epithelia in the nasal cavity, orbit, and oral region provide the opportunity for evaporative cooling of blood running through submucosal veins, as well as warming of that same blood during basking. The intent has been to discover anatomical homologies that potentially can provide insight into commonalities in physiological strategies. By establishing the anatomical framework in extant diapsids, where physiological testing is feasible, the ultimate goal is to shed light on the osteological correlates of these physiological strategies in extinct diapsids, such as dinosaurs, allowing the testing of hypotheses for how these animals, many of which were giants, could have managed their high heat loads. Answering those larger questions starts with detailed investigations of the blood vessels of their extant relatives.
