The reading and the lecture are both about the elephant-size dinosaur’s likely migration during extremely cold and dark winters in Alaska. Accordingly, the author provides three theories to prove the notion. On the other hand, the professor is not convinced of the claim and casts doubt on each of the theories presented in the passage. The lecturer is of the opinion that hardly these claims are capable of giving credence to this migration.
Firstly, author argues that these animals were dependent on plant as the only source of their food. Since scarcely plants could grow in the harsh and frigid climate of the region, dinosaurs were pushed to migrate to find food. This specific argument is challenged by the lecturer. According to the professor, 100 million years ago the weather seems to be warmer than today, and 24-hour sunshine right in the middle of sky in the summer lead to plants grow exceedingly and profoundly. Subsequently, all the plants died in the winter, and could produce a bunch of notorious dead plants which could feed dinosaurs without migrating.
Secondly, the writer disputes finding many skeletons of dinosaurs in the region lead to concluding the fact they lived in herds; Therefore, they could have migrated because living in herd help to migrate. The lecture, in contrast, opposes the notion by asserting that living in herds can occur because of other reasons including protection against enemies. The professor presented an example of Rosa welt which lives in forest in order to support her claim that not all animals living in herds immigrate downright.
Finally, the writer averts although there was a long distance between their habitat and the destination of migration, however these animals could run fast and were able of this departure. The lecturer’s stance is that the writer has not considered the young ones which were not physically prepare for these long distances. Moreover, she points outs that the young animals slowed down the herd from running and adults were not capable of living them behind because they could not protect themselves.
