Question

Quizplus · Accepted Answer

Feathers do not contain hard parts, such as bones or shells, which are more likely to preserve in the fossil record. Feathers are made of keratin, which is a relatively soft and organic material that decomposes quickly. Additionally, birds are often found in environments that are not conducive to fossil preservation, such as forests with high oxygen levels that can speed up decay. Some exceptional preservation of feathers has been found in certain rare conditions, such as in fine-grained sediments or in amber.
