The lecturer and reading passage hold different view toward whether dinosaurs were endotherms or not.
First, the reading passage states that dinosaur fossils have been discovered in polar regions, so the dinosaurs were endotherms. In contrast, the lecturer states that dinosaurs were not endotherms, because the polar regions at that time were very warm. And even the polar regions were cold, dinosaurs may migrated to other places or hibernated during the winter.
Second, the lecturer argues that dinosaurs used legs to hold huge bodies, which were an advantage for dinosaurs. The reading, however, argues that dinosaurs could run very fast because its legs are underneath body, which is the sign for endotherms.
Finally, the reading passage believes the dinosaurs were endotherms due to the Haversian canals. On the other hand, the lecturer states dinosaurs also had growth ring, which recorded dinosaurs' growth rates. It indicates that dinosaurs had periods of rapid growth and periods of no growth in succession. If the dinosaurs were endotherms, they must have constant growth rates.
