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.
Based on the given materials, the reading as well as the lecturer discusses migration of an ancient animal called edmontosaur. The author states that these animals were capable of migration but the lecturer provide several reasons to argue this claim.
Initially, the writer mentions that since edmontosaur's diet was made of vegitation, during the winter they could not have found enough food to survive and as a result they had to migrate. However, the speaker suggests otherwise because the summer condition were so good that there were plenty of food around. The summers of that area were warm and the sun shone 24 hours per day providing a perfect condition for plants to grow and consequently during winters dead plants were abundant providing plentiful nutrients for the animal.
Second, the author conclude that since the fossils of the animal were found in a concentrated place, they had been living in herds. Based on todays animal that are livining in a herd and they migrate, the reading suggests that edmontosaurs migrated too. Yet again, the lecturer underscours that there are some animals that live among a herd but they do not migrate since living in a herd have other benefits too such as having more protection.
The last contention between the reading and listening passages is the animal's physical abbilities. The author of the reading suggest that edmontosaurs were capable of making long distance journeis. On the other hand, the speaker points out juveniles and their disability too walk as long as a grown one. She explains that the younger could have slowed the herd so much that it was impossible to make the journey. She also states that the younger animals could not have been left behind because they were dipendaning on the grown mammels so consequently the adult animals should have stayed to keep them alive.
