A fossil skeleton of a dinosaur called Sinosauropteryx, preserved in volcanic ash, was discovered in Liaoning, China, in 1996. Interestingly, the fossil included a pattern of fine lines surrounding the skeletal bones. Some paleontologists interpret the lines as evidence that Sinosauropteryx had feathers. However, critics have opposed the idea that Sinosauropteryx was a feathered dinosaur, citing several reasons. First, the critics points out that the fine lines may not even represent functional structures of a living dinosaur, but rather structures that were formed after the animal’s death. After the animal died and was buried in volcanic ash, its skin may have decomposed into fibers. The skin fibers then became preserved as lines in the fossil; the lines were misinterpreted as evidence of feathers. Second, even if the fine lines are remains of real structures of a Sinosauropteryx, scientists cannot tell with certainty what part of the dinosaur’s anatomy the structures were. Many dinosaurs had frills, ornamental fan-shaped structures growing out of some parts of their bodies. Some of the critics argue that the lines surrounding the skeleton are much more likely to be fossilized remains of frills than remains of feathers. A third objection is based on the fact that the usual functions of feathers are to help animals fly or regulate their internal temperature. However, the structures represented by the lines in the Sinosauropteryx fossil were mostly located along the backbone and the tail of the animal. This would have made the structures quite useless for flight and of very limited use in thermoregulation. This suggests that the lines do not represent feathers.

The reading passage presents the view that the linear pattern discovered in fossil does not imply that Sinosauropteryx had feathers for three reasons. The lecturer, however, disagrees with the reading, arguing that all three reasons are inconvincing. First, the reading passage states that the lines were formed by the fibres produced by the decomposition of Sinosauropteryx's skin instead of remains of feathers. But the lecturer objects to this point, claiming that, provided that other animal fossils discovered at the same site have well-preserved skin structures, there is no chance for the skin of Sinosauropteryx to decompose into fibres. Therefore, the lines cannot be formed by fibres and should be actual structures like feathers. Second, the reading passage maintains that there is a higher possiblity for the lines to be remains of frills of Sinosauropteryx rather than its feathers. In contrast, the lecturer refutes this idea and contends that frills and feathers have a major difference in chemical composition-feathers have a specific protein compound but frills do not. Analysis es indicates that the lines involves that particular type of protein, suggesting that the lines were feathers instead of frills. Third, the passage claims that the lines locate at the back bones and tail of the Sinosauropteryx, making the feathers useless in flight and maintaining warmth, thus feathers wouldn't have grown in that location. On the contrary, the lecturer is against this argument, pointing out that other than being a tool for flight and thermoregulation, feathers might have acted for displaying functions, helping the Sinosauropteryx attrach mates. In addition, scientific discoveries show that Sinosauropteryx were in vibrant orange and white colors, strengthening the hypothesis that the feathers were used for displaying. Therefore, the feathers could have proper functions and the lines stand a great probability of being remains of feathers.
