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 explains that for some reason the pattern of fine lines surrounding the skeletal bones of sinosauropteryx are not the strong evidence to point out that kind of dinosaur had feather, whereas the lecture challenges this view for some reason.
the speaker says that there are not any similar sign in other animals. this acknowledge contradicts the reading assertion that this sign are not functional and they may be created after death of dinosaur and by volcano effects.
the lecturer also refutes the reading claim that if this sign be important, they must be frills instead of feather. also she says that there are some chemical differences between frills and feathers and this chemical feature is "cariton",that is very lot in frill an not common in feather,and at in the fossils there are very low cariton so they must be feather .
finally the speaker is not convienced that the palce of this sign was back bone and tail of the fossil so they must were not for fly or body tempeture so they were not feather, and she claims that like some other animals there were for dispaling purepos and it is very common that they was feather.
at the end speaker claims that this evidence are strongly proof of the feather in that period of time .
