Reading Part:
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

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
