Chronological methods 8 radiocarbon dating
Radiocarbon dates can be obtained from many types of organic material including charcoal, shell, wood, bone and hair.The amount of carbon dioxide in the living organism is equal to that in the atmosphere.Three types of carbon occur naturally in living material: C12, C13 and C14.Carbon14 (C14) is unstable and present in a very small percentage relative to the other components.

For example, an age can be estimated for a strata of rock based on the age of the skeletons it holds. Libby, a professor at the University of Chicago, in 1949.
