According to the lecture,dinosaurs were not supposed to be endotherms.This contradicts the point in the reading that dinosaurs were greatly likely to be endotherms.

First of all,the speaker argues that fossils discoveres in polar regions can't tell that dinosaurs were endotherms.By contrast,the reading believes that the fossils discovered give a proof of dinosaurs used to live in polar regions, which indicates that they could maintain a temperature well in such harsh weather.From the speaker,the climate in polar regions may be much warmer before.Even if not, dinosaurs could immigrate to other inhabitants or do a hiberation.

Also,the speaker raises the issue that the leg position of dinosaurs doesn't represent high energy,which is different from what is stated in the reading that the leg position of dinosaurs strongly suggests that dinosaurs were entherms.The speaker tells us that leg growed underneath the body in order to support more weight because dinosaurs usually have large sizes.

In addition,the speaker rebuts the reading by emphasizing that there is a growth ring in the body of a dinosaur as well as the Harversian canal.
This totally opposes the viewpoint made in the reading material that Harversian canals allowd body to grow quickly, which is the sign of entherms.In order to illustrate her point, the speaker provides us the instance that the growth ring would inhibit rapid growth and there is a evidence that dinosaurs growed slowly during the cooler period.

Therefore, the speaker has  totally different opinions from the points made in the reading.
