The reading states about that we can find dinosaurs were endotherms and provides three reasons of support. However, the professor in the lecture casts serious doubt on the passage by using a number of points that are contrary to each of the author's reasons.

First, the reading claims that dinosaur's fossils have been discovered in Polar Regions and just endotherms can live in this region. The professor refutes this point by saying about emigrant. He states that dinosaurs use emigration when they feel so cold to other places.

On another hand, the article posits that about relationship of leg position and movement of dinosaurs to endothem. However, the professor describes that there is no necessary relationship between them. According to the professor legs can prove that dinosaurs were so large.

Finally, the reading makes it clear that we can find dinosaurs were enthoderm by researching their bone structures. The professor opposes this point by taking about growing. We also learn that endotherm will stop growth or make it slower in cooler periods.
