This debate first began in the late 1960s with the discovery of the Deinonychus by Yale's John Ostrum who suggested warm-bloodedness. In the following section, we will discuss the most common evidence used to infer the metabolic nature of dinosaurs. First, more about metabolism of reptiles and mammals. Require more food per body weight to maintain higher temperature than reptiles. 2. allows greater level of activity because of higher metabolism which is created by burning food with oxygen, releasing carbon dioxide, water, and heat energy.
Body temperature can vary depending on external environment.
I will not provide detailed notes of this subject. Other dinosaurs do not have growth rings. To be endothermic, dinosaurs needed to process efficiently. Perhaps these just reflect a preference for tough food. Large dinosaurs, such as sauropods, would have been gigantotherms or inertial homeotherms that maintained a relatively constant body temperature by virtue of their large body mass.
