The reading states that a Sinosauropteryx's fossil skeleton which had been preserved in volcanic ash has been discovered in China, and it contained subtle lines around the bones. Some researchers believe they are feathers, while others refute this claim in several ways. The professor finds the evidence convincing enough for the existence of feathers on the animal's body and rejects the critics' ideas in what follows.
First, the text points out that these lines may not be signs of functional parts during the creature's life, but they are were created after its death and due to the decomposition of its skin. The speaker denies this argument in that she propounds the same pattern had not been seen in any other fossils. Besides, the functional skin structures of other animals have been well preserved in volcanic ash. Thus, these lines can probably be the signs of functional structures of the animal - i.e. feathers.
Next, the reading observes that even if these are the signs of functional structures, no one can say exactly which parts they were; in particular, they can be remnants of frills of the dinosaur. The professor adds that the frills did not contain a special protein, called bethacarothinBeta-keratin, while there is evidence that these lines contain the mentioned protheinprotein. So she does not find this opposition sensible as well.
Finally, the passage mentions that feathers help animals fly or regulate their body's heat, while the claimed feathers on the dinosaur are located mostly on the backbone and its tail; hence, they cannot be feathers. The listening rejects this idea by stating that, as an example, the peacocks have feathers on their tails which are merely for display purposes and not the aforementioned ones. Especially the feathers of the dinosaur are found to be white and orange which proves that they are some feathers for the same end.
