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.
The reading passage and the lecture hold conflicting ideas about whether a kind of dinosaur called Edmontosaurus was a migratory species or not. While the reading passage seems to have strong arguments for the migration hypothesis, the professor thinks that there are huge flaws in such claim.
First, unlike the reading passage which states that there would not have been any plants available during the long-lasting polar night in the North Slope region, thus forcing these animals to migrate to warmer zones for food, the professor explains that Edmontosaur could stay and feed on the abundant remains of the dead plant because a large amount of vegetation was produced during the summer at whose peak the nature was exposed to the polar day.
Second, the reading passage shows that based on the fossil findings Edmontosaurs lived in herds and probably took advantage of such survival strategy for a better coordinated migration as what modern migrating animals do. However, the professor says that living in herds isn’t necessarily a direct link to migrating because such animal society can also provide extra protection from predators. For example, Roosevelt elks which live together but don’t migrate are a vivid example in the modern day.
Third, although it is said in the reading passage that Edmontosaurs could make it to their final destination because they were able to migrate long distance with quite fast speed as well as amazing endurance, the professor thinks differently. The reason is that juvenile Edmontosaurs were not as physically strong as adult Edmontosaurs. As a result, they would not be able to reach the warmer destination and even would have slowed down the march of the whole herd. The herd had to stay with the young because they could not have survived without the adult dinosaurs.
