To begin with, the paragraph asserts that the fine lines were the fibers decomposed from skin preserved in the fossil instead of functional structures. Contrary to the reading, the lecture refutes that the fine lines are indeed functional structures, potentially feathers of a living dinosaur. It is infeasible that the skin may have decomposed into fibers because there is no such decomposition discovered in other animal fossils. Furthermore, the functional skin structure were well-preserved in volcanic ash,
