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 and the lecture are both about the migration hypothesis of Edmontosaurus from the North slope to the south. The author of the reading argues that there are some arguments support the migration hypothesis. The lecturer cast doubts on the claims made in the article. She thinks that this hypothesis is not convincing.
First of all, the author claims that the lack of sources during the winter in the North slope galvanized Edmontosaurus migration to the South. This point is challenged by saying that Edmontosaurus do not have to migrate to find food. She states that during the summer, vegetation grew remarkably in the North, however, in the winter Edmontosaurus fed on died vegetation.
Second, the article posits that some findings have revealed that Edmontosaurus lived in herds which helped in the migration process. However, the professor says that living in herds is sometimes to give extra protection from predators. According to the professor, the best example of this case is the rose fold elks which live in herds but do not migrate.
Third, the reading says that Edmontosaurus had the power and strength to travel long distances. The professor opposes this point by explaining that only adult Edmontosaurus was capable to migrate long distances. She argues that junior could not move these distances and might slow the herds, as a result, herds would stay with juniors and do not migrate.
