Was the lines near Sinosauropteryx's fossil related to feathers?
The article discusses about evidences that opposes the claim of some researches that the lines in a newly-found fossil of Sinosauropteryx is an indicator of them having feathers. The author supports his ideas with three reasons, however, the professor in the lecture takes these evidences as unconvincing and opposes each of them.
First, the article claims that the feathers are most likely to be decomposed and the lines cannot be representative of anything meaningful. However, the professor avers that there were another fossils of well-known animals in the same site which were preserved very well and no evidence of decomposition was observed so we can believe that the lines are related to the exact form of the animal.
Second, the passage states that scientists cannot tell for sure to what part of the Sinosauropteryx's anatomy the lines are related since dinosaurs had lots of similar parts such as frills. Even though the lecturer agrees that the dinosaurs has parts like frills but she states that the frills and feathers have a chemical difference. The feathers have a material named beta-carotene in their structure but frills do not have it, hence the lines cannot be related to frills.
Third, the reading avers that the feathers have to functions in animals, flying or thermoregulation, and since the lines were mostly along the backbone it is very unlikely to have any functions. However, the professor explains that feathers may have other functionalities. She provide an example of peacock who use its feathers and tail to attract mates and it has a display function. Furthermore she avers that the studies had shown that their feather was colorful, therefore, they might had a display function.
