The reading and the lecture are both about a Sinosauropteryx's fossil skeleton, which has a particular pattern of fine lines surrounding his skeleton. The author of the reading claims that this pattern of lines is not the remains of feathers, whereas the lecturer believes that these lines are a strong evidence that the Sinosauropteryx had feathers.
First of all, the author contends that the lines could not even be a functional structure of a living dinosaur, but rather a structure formed at a later stage. Furthermore, he thinks that the lines could also be the residual fiber from skin decomposition. The lecturer debuts this claims using the example of other fossils discovered in the same area, which have no evidence of skin decomposition, so the theory of fiber is likely wrong.
Second, the author argues that not even the scientists have identified precisely if this was a real body structure which belongs to the dinosaur. The author suggests that it might be an ornamental structure such as frills. The lecturer, on the other hand, excludes that it can be frills, mentioning that chemical analysis has shown the presence of Beta-carotene, which is normally present only in feathers and not in frills.
Finally, the lecturer points out that the feathers have not only a function to regulate the internal temperature or assist the animal when flying, but often feathers are used to attracts mates and for displays, therefore, the position over the spine bone and tail could be the remains of feather used for mating.
