The article states about some doubts among critics of a new fossil related to discovery of a skeleton towards Sinosauropteryx Dinosaur that this fossil does not have any evidence of feathered Dinosaur. The article provides three reasons to support this idea. However, the professor in the lecture casts serious doubt on the passage by using a number of points that are contrary to each of the author's reasons.

First of all, the reading claims that the fine lines on the body of Dinosaur may have created after his death. In contrast, the professor refutes this point by saying that it is not true because we discover Dinosaur's body among ash of volcano and so eruption can maintain any stuff without any change. The professor mentions that there is not any evidence to decomposition.

On another hand, the article posits that the remains are not so clear and it may be related to fibers instead of feathers. However, the teacher describes that they have found some kind of protein that is especially related to feathers. According to the professor this protein cannot be in any part of the Dinosaur's body like fiber.

Finally, the article makes it clear that the position of feathers on the Dinosaur's body is not true and its structure is irrational. Conversely, the lecturer opposes this perspective by explaining that these feathers may have other uses. We also learn that these feathers have bright and orange colors. So, there is a strong idea that there were useful to display and as a result to attract mates.
