The reading and lecture both discuss the possible explanation of the fine lines of a Sinosauropteryx dinosaur. While the reading provides three claims to support the idea that these fine lines were not related to the feathers, the professor refutes saying, none of these claims are convincing.
Firstly, the reading avers that these lines did not have any functional structures, but these were a just a skin decomposition into fibers. However, the professor argues this notion saying that the lines on fossil unlike decomposition. This is because there was not a such decomposition in fossil of any other animals. In addition, other animals were well preserved and the researchers could not find any lines. So, these lines were functional structures.
Secondly, the article mentions that the scientists could not identify the anatomy of these lines and these might be just a remains of frills. On the other hand, the professor rejects this idea by pointing out that there is different between the composition of feathers and frills. In fact, the frills decomposition contains protein, but the feathers decomposition contains keratin not protein. In addition, the chemical composition of these lines contain keratin. So, these lines were feathers not frills.
Lastly, the reading states that the location of lines along the backbone confirms that there is no function of these lines to help the animals to fly or to control the body temperature. Nevertheless, the professor contradicts this idea by explaining that there is another functions of feathers. For instance, the pink heck has feathers on the tail. These feathers are colorful with a bright orange color. So, this bird uses these attractive feathers to attract the mates. So, this function called display function. Consequently, these feathers lines had a display function.
