Short summary
Based on the estimation of its body mass and metabolic rate, we calculated heat balance, gas exchange, osmoregulation, and digestion of the 290-million-year-old aquatic amphibian Archegosaurus. Our results suggest that its physiology was more fish- than tetrapod-like in many respects. We conducted this study, which is mainly based on theoretical calculations and comparison with extant analogs, to shed light on the physiology and lifestyle of early tetrapods.
