This chapter examines the physiology, metabolism, and behavior of dinosaurs. It discusses the evolution of endothermy and examines the typological and transformational approaches to dinosaurian physiology. The chapter also contends that (1) dinosaurs were, in many respects, more like living large birds and mammals than they were like living reptiles; (2) more physiological advances occurred at or near the origin of dinosaurs than at the origin of birds; (3) not all dinosaurs were alike in these physiological respects, any more than living mammals or birds are all alike; and (4) comparative biology is a better guide to evolutionary paleobiology than typology is.

Keywords:   physiology, metabolism, behavior, dinosaurs, endothermy, comparative biology, evolutionary paleobiology, typology
