are Sinosauropteryx fossils feather remnants or not has been updated.
First of all, the author mentions that the fine lines maybe do not represent remnance of functional structures, and they can be parts of animal skin. Meanwhile, the lecturer highlights that these kind of marks can be left only by functional structures. Moreover, she points out that it is a common feature in other fossils found.
The second evidence that the author emphasizes is the fact that scientists cannot say exactly which part of the body the lines belong. They can be signs of the frills of the animal. The lecturer argues on this idea with mentioning that frills and feathers have different chemical composition. Whereas, the lines do contain beta-carotene which is a special part of feathers.
The author's last argument is the functional uselessness of feathers of this construction. The lecturer contradicts this point by pointing out that feathers could be used to allure a pair, which means it had a display function. This is likely because the feathers were colorful orange and white.
To sum up the passage, the author mentions that the fine lines cannot be remnance of feathers and even presents evidences to prove this point of view. In turn, the lecturer highlights some reasonable features which prove that the animal did have feathers.
