Question: Can you date a fossil?

Fossils themselves, and the sedimentary rocks they are found in, are very difficult to date directly. Instead, other methods are used to work out a fossils age. These include radiometric dating of volcanic layers above or below the fossils or by comparisons to similar rocks and fossils of known ages.

Can a single fossil be dated by itself?

Fossils themselves usually cannot be directly dated radiometrically because they dont usually contain radioactive minerals. We must therefore combine information from fossils and radiometric dates from rock layers above or below to answer the question, “How do Scientists Date Rocks and Fossils?”
