In the set of materials we can know that the dinosaurs were endfotherms from the evidence in teh reading part. While, in the lecture we get some different information.
First of all, the professor in the lecture tell us that the polar dinosaures fossils could not prove that dinosaurs were endotherms because the temperature in polar was quite warmer than today. When the cold period of a year came in polar the dinosaures could not move to other areas like modern dinosaures, however, they could still live there. That means the dinosaures were not endotherms.
Talking about the leg position and movement of dinosaures, the professor says the reason why the legs of the dinosaures were under the body is that they wanted to support the weight of their large bodies.And the body structure could suggests that dinosaurs were endotherms.
At last, we can know from the lecture that we can see the growth rings in the Haversian canals which indicate that dinosaures growed slowly or even stopped growing in cold period and growed fast in warm period. If they were endotherms they would grow in the same pace. So the found of Haversian canals could not prove the dinosaures were endotherms.

总体不错,上回的问题都克服了,这篇的问题可能是第二个没有联系阅读文章,整体还是很有提高的,小三儿加油!
