This chapter examines the paleophysiology of nonavian dinosaurs. It describes the physiological and functional aspects of dinosaurs and focuses on two distinct physiological attributes: thermoregulation and aerobic capacity. New evidence pertaining to dinosaur energetics and thermoregulation is examined. The chapter discusses respiratory turbinates, resting metabolic rates, lung structure, ventilation, elevated active metabolic rates, and the relationship between bone microstructure and thermoregulation in nonavian dinosaurs.

Keywords: paleophysiology; nonavian dinosaurs; thermoregulation; aerobic capacity; respiratory turbinates; metabolic rates; ventilation; bone microstructure
