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 edmontosaru 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 edmontosaurs had to migrate about 1600 kilometers southward. To make such a journey, the edmontosaur needed to move at about five kilometers per hour for several weeks, which it 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 and lecture have conflicting opinions about whether or not dinosaurs migrated from the North in winter periods to a warmer areas to survive. The article strongly postulates that there are many arguments support that edmontosaur migrated in winter to the south. On the other hand, the listening adamantly delinates that none of the assumption presented are plausible.
First and foremost, according to the author of the excerpt, the winter in south wouldn't fit the edmontosaur's food style. In other words, there coudn't have been plants growing in the winter, which is the main source of food for edmontosaur's. Nonetheless, the lecture offsets these points by declaring that edmontosaur's would have been able to find food in the summer. Also, the summer temperatuer is very warm owing to the fact that the sunshine for 24 days at peak. Meaning that a lot of plants would have grown during the summer. However, in the cold periods, edmontosaur's would have fed on the Nutrition of the dead plant.
On top of this, the professor further points out that even if edmontosaur's would have lived in herds, that doesn't mean they would migrate. Moreover, Living in herds provide extra protection from predators. For example, Rosset elk is a large plant eater that lives in herds and don't migrate. These claims refute the writer implication of how edmontosaur's may have been migrating in cold winter because they were living in herds.
The article lastly asserts that edmontosaur's had the ability to migrate long distances. In other words, these dinosaurs would have been traveling 1,600 kilometers to the south. The speaker in lecture counters these points by insisting that the young edmontosaur's would have been slowing the adult's of the edmontosaur's. which means they would slow the herds. Also, other dinosaurs didn't have the power to travel such a distance. Consequently, north dinosaurs would have stayed and survived in the cold north.
