How can you find the age of fossiles ?

Explanation

(i)The age of fossils is determined by radioactive elements present in it.
(ii)They may be cvarbon,uranium,lead or potassium.It is used in paleobotany and anthropology for determining the age of human fossils and manuscripts.
Radioactive carbon (`C^(14)`) dating method:
(i)This method was discovered by W.F Libby (1956).
(ii)Carbon consumption of animals and plants stops after death and since then,only the decaying process of `C^(14)` occurs continously.
(iii)The time passed since death of a plant or animal can be calculatedd by measuring the amount of `C^(14)` present in their body.
