Two ways by which age of fossils can be estimated:

• Relative method: This method tells that the fossils which are closer to the earth's surface have been more recent and as we go deeper they are older.

• Carbon Dating: Isotope of Carbon C - 14 for finding the age of the fossil.

• Radiometric Dating: This can be done easily by testing the radioactive present in the fossils and thoroughly examining it chemically in the best way possible.
