Large number of plants and animals get buried in the earth due to natural calamity such as earthquake, volcano, and flood. Remains (parts of the body) and impressions of such organisms remain preserved underground are known as Fossils . Examples include bones, shells, exoskeletons, stone imprints of animals, etc.
The time of death of a plant or animal can be calculated by measuring the radioactive carbon(C-14) in the fossil. By determining the age of the fossil, the information about other organisms can be gathered which helps in study of evolution.
