Large numbers of dinosaur fossils have been discovered in deposits on Alaska's North Slope, a region that today experiences an extremely cold, arctic climate. One hundred million years ago, when those dinosaurs were alive, the environment of the North Slope was already inhospitable, especially during the winter when it experienced several months of total darkness. How did the dinosaurs survive the wintertime? Paleontologists have proposed that one of the most common North Slope dinosaurs, the elephant-sized edmontosaur (Edmontosaurus), survived the winter by migrating south to more hospitable regions. Several arguments support the migration hypothesis. First, the edmontosaur's diet supports the migration hypothesis. Edmontosaurs fed exclusively on plants. Since there would have been no plants growing during the cold and dark North Slope winter, it appears that the edmontosaur must have left for at least part of the year and migrated to more temperate zones to find food. Second, many edmontosaur skeletons have been unearthed from the same site. This suggests that edmontosaurs lived in herd. Many modern-day migratory animals, such as caribou and buffalo, live and migrate in herds as well. Moving in herds helps animals coordinate their migration. The finding that edmonotsaurs lived in herds further supports the migration hypothesis. Finally, edmonosaurs were physically capable of migrating long distances. To reach more hospitable regions, the edmontosaur had to migrate about 1,600 kilometers southward. To make such a journey, the edmontosaur needed to move at about five kilometers per hour for several weeks, which is certainly could do. These animals could run very fast, reaching speeds up to 45 kilometers per hour. It could have easily used its locomotive power to move to warmer climate during the harsh arctic winters.
The reading passage argues that a species of dinosaurs must have migrated south in the winter to avoid the harsh conditions on the North slope. However, the speaker in the lecture refutes the claims made in the article. She mentions that the three arguments are unconvincing.
First of all, the author holds that the edmonosaurs were exclusively herbivores, which means they fed only on plants. According to the article, since no plants grew on the North slope in the dark cold winter, they must have migrated south to find food. Conversely, the lecturer challenges this point of view. She posits that In the summer, the sunshine was on the North slope 24 hours per day, which would have created perfect conditions for plant growth. She further elaborates that those plants which would have been dead by the winter could have served as a highly nutritious source for Edmonosaurs. Hence, these dinosaurs would not have had to migrate as they would have been able to feed on dead vegetation.
Secondly, the writer assumes living in herds proves that Edmonosaurs had a migratory pattern. In contrast, the lecturer brings the fact that other reasons exist for animals to live in herds. For example, a herd provides extra protection against predators. In addition, the lecture illustrates that other animals live in herds but do not migrate, such as this kind of elk that lives west of the United States.
Lastly, the excerpt postulates that this type of dinosaurs had the necessary physical capabilities required to travel long distances to reach warmer climates. Nevertheless, The lecturer points out that this could have been true only for adult animals. On the contrary, juveniles would not have had this physical capacity to withstand long trips, which would have slowed down the herd because they would not have left their young falling behind. Consequently, this hypothesis does not seem feasible.
