are remnants on Sinosauropteryx fossils those of feathers or not
While in the reading part the author presents some evidence, which shows that lines found on Sinosauropteryx fossils cannot be the remnants remanence of feathers, the lecturer is strongly confident that they can. . The points to elaborate on the very contradiction are presented below.
First of all, the author mentions that the fine lines maybe do not represent remains of functional structures, and they can just be parts of animal skin. Meanwhile, the lecturer highlights that these kinds of marks could have been left only by functional structures. Moreover, she points out that it is a common feature in other fossils found too.
The second evidence that the author emphasizes is the fact that scientists cannot say exactly which part of the body the lines belong to. Most probably, They can be signs of the frills of the animal. The lecturer argues on this idea mentioning that frills and feathers have a different chemical composition. Whereas, the lines do contain beta-carotene which is a special part of feathers.
The author's last argument posited by the author is the functional uselessness of feathers of this construction. The lecturer contradicts this viewpoint by pointing out that feathers could be used to allure a mate , which means they it had a display function. This is likely to be the case because the feathers were colorful, especially orange and white.
To sum up all the arguments of both pieces of the material the passage, it turns out to be obvious that as the author mentions the fine lines cannot be remnants of feathers and even presents evidence to support this point of view. In turn, the lecturer highlights some reasonable features which prove that the animal did have feathers depicted in the fossils.
