Why is it important to date fossils?

Dating of the fossils contributes to a clearer timeline of evolutionary history. Older methods of dating were more subjective, often an educated hypothesis based on the evidence available.

Is knowing the age of fossil is significant?

Determining the ages of fossils is an important step in mapping out how life evolved across geologic time. Biostratigraphy enables scientists to match rocks with particular fossils to other rocks with those fossils to determine age.
