In the reading passage provided above, it is debated heatedly that whether the dinosaur were endotherms which are able to maintain their body temperature constantly.

The first evidence that dinosaurs’ fossils have been discovered in polar regions illustrate the fact of endotherms. However , the professor argues that it is warmer in polar areas than today. Even if the climate there becomes cold, dinosaurs would migrate to warmer places or hibernate like other animals. So fossils found there do not prove sufficiently the opinion that dinosaurs are endotherms.
The second evidence is given that the legs of all modern endotherms are beneath the body, which is different from crocodiles. The professor refuted that since large sized animals such as dinosaurs grow rapidly, though needing high energy to run around, it is necessary for the dinosaurs to have legs under the body to support the weigh.
The last point stands that the presence of Haversian in bone is a strong indication for endotherms. It is true that growing rings exist in the bones, which indicate the periods dinosaurs grow. When it comes to be cooler, they would stop growing. The rings also suggest that alternate changes between rapid and slow period of growing, which also illustrate strongly that dinosaurs are not endotherms.
