Endotherms are animals such as modern birds and mammals that keep their body temperatures constant. For instance, humans are endotherms and maintain an internal temperature of 37°C, no matter whether the environment is warm or cold. Because dinosaurs were reptiles, and modern reptiles are not endotherms, it was long assumed that dinosaurs were not endotherms. However, dinosaurs differ in many ways from modem reptiles, and there is now considerable evidence that dinosaurs were, in fact, endotherms.
Polar dinosaurs
One reason for believing that dinosaurs were endotherms is that dinosaur fossils have been discovered in polar regions. Only animals that can maintain a temperature well above that of the surrounding environment could be active in such cold climates.
Leg position and movement
There is a connection between endothermy and the position and movement of the legs. The physiology of endothermy allows sustained physical activity, such as running. But running is efficient only if an animal's legs are positioned underneath its body, not at the body's side, as they are for crocodiles and many lizards. The legs of all modern endotherms are underneath the body, and so were the legs of dinosaurs. This strongly suggests that dinosaurs were endotherms.
Haversian canals
There is also a connection between endothermy and bone structure. The bones of endotherms usually include structures called Haversian canals. These canals house nerves and blood vessels that allow the living animal to grow quickly, and rapid body growth is in fact a characteristic of endothermy. The presence of Haversian canals in bone is a strong indicator that the animal is an endotherm, and fossilized bones of dinosaurs are usually dense with Haversian canals.
The article and the author are both about dinosaurs are endotherms or not. The author of reading feels that dinosaurs were endotherms given by evidences. The lecturer challenges the claims made by the author. The lecturer thinks that dinosaurs were not endotherms.
First of all, the author argues that dinosaurs’ fossils have been discovered in polar region. The article is mentioned that these animals can maintain temperature could be active in various surrounding temperature. This point is challenged by the lecturer. He claims dinosaurs were live in cold climate. Furthermore, he says they migrate polar region to other places while change the cold climate.
Secondly, the author suggests that dinosaur has connection in the between endothermy and the position and movement of the legs. Its notes that underneath leg is in modern endotherms. The lecturer debuts this argument. He suggests underneath leg help keep high energy for while running. He elaborates on this by mentioning that its help for maintain large body weight.
Finally, the author states that there are connection between endothermy and bone structure. Moreover, It says that haversian canals in bones indicate the dinosaurs’ fossils. In contrast, the lecturer’s position is that these canals in bone is grow rapidly according to climate. He says that this is evidence for showing dinosaurs are not under the endotherm.
