Based on the given materials, the article as well as the lecture discusses a fossil skeleton of Sinosauropteryx, which is a preserved dinosaur in China in 1996, and some researchers have seen several lines which make the researchers thinking about whether the dinosaur had feathers or not. The author states that there are several viable theories shows that these lines are not places of former feathers. That being said, the lecturer provides several ideas to repudiate this claim.
Initially, the author says that the lines had been remained after the Sinosauropteryx's body buried in volcanic ash and its skin decomposed into fibers. However, the lecturer explains that there were not seen any such decomposed body of other animals, and also the dinosaur's functional skin structure was completely preserved in volcanic ash. So, this functional structure, played a role as the feather.
Second, the writer proclaims that many dinosaurs had some fan-shaped structures, called frills; some researchers say that these fine lines might be remaining parts of frills, not feathers. Yet again, the speaker underscores some chemical differences between frills and feathers. Feathers, as opposite to frills, contain some proteins, named Beta-keratin. By doing chemical analysis on the dinosaur's fossil, paleontologists found several amounts of Beta-keratin, which shows that the lines are related to the feathers.
The final point of contention between the reading and the listening passage is function of the feathers in such animals. The author thinks that, because of locating lines at the backbone area, the possible feathers might be useless for flight and districted effects for regulating temperature of their body. On the other hand, the speaker explains that feathers in animals not only have flighting functions but also display functions, like some species of birds which use their colorful feathers to attract mates. In addition, based on some researches on color, the dinosaur's feathers might be orange and white, which increase the possibility of using for display functions.
