Sinosauropteryx feathers
The reading passage and the lecture are both about a pattern of fine lines surrounding the fossilized skeleton of Sinosauropteryx. The writer disagrees with the idea that these lines represent feathers and gives several reasons to support this statement. As reasonable as these points seem, the professor in the lecture casts doubt on them, indicating that Sinosauropteryx was a feathered dinosaur.
To begin with, the author states that it was skin fibers that constituted these line structures after this dinosaur died. Nevertheless, disputing the passage’s argument, the lecturer cites other animals’ well-preserved fossils of skin structures showing that Sinosauropteryx’s lines probably were functional structures as well. Therefore, the lecturer claims that these lines weren’t composed of decompositions of skins.
Second, the lecturer acutely identifies a weakness in the article that these lines were fossilized remains of frills rather than feathers. She details that frills were chemically different from feathers. Feathers embodied a special protein which was also examined in Sinosauropteryx’s lines. Accordingly, the lecturer rules out the possibility that these lines were frills.
Last but not least, even though the author illustrates that the lines were mostly situated along the backbone and tail of Sinosauropteryx, implying that the lines were unlikely to be harnessed to fly as feathers, the lecturer argues that it is a misconception. This is because feathers can serve other functions. With a view to establishing a more solid and concrete explanation, the lecturer cites peacocks as an example. Peacocks display their feathers to attract a mate. Furthermore, she points out that recent analyses show that these line structures were colorful. As a result, she strongly believes that the fossilized lines were feathers of this dinosaur.
