Developed by a team of researchers under the leadership of Dr.Willard Libby, this technique had revolutionized the way the archaeological advancements are made in learning about the past civilization and cultures, changes occurred in the earth and in its climate.Archaeologists utilize one of the revolutionary methods called the radio carbon dating to determine the approximate age of the organic materials including plant and animal parts up to 50000 years (Long).Radiocarbon dating technique is primarily based on the radioactive decay of Carbon-14 isotope.Radiocarbon dating enable archaeologists to provide proof of authenticity to the excavated artifacts’ period of usage and thus by collaborating with the efforts with historians and anthropologists, the unwritten history can be precisely explained.Significance Desmond Clark (1979) opinions that if radio carbon dating technique were not discovered, (Clark, 1979:7). Exploratory analysis of the international radiocarbon cross- calibration data: consensus values and interlaboratory error. Then the amount of carbon-12 in the body will not reduce but the amount of carbon-14 undergoes reduction due its radioactivity. Carbon-14 isotope will undergo decay at an exponential rate to form the stable nitrogen-14. The following equation is used to determine the carbon-14 decay.

Carbon and oxygen isotope composition of mollusk shells from marine and fresh-water environments.

Prior to the development of radiocarbon dating it was difficult to determine the age of the artifacts unless it was accompanied with some chronologically specific things like a coin.

Otherwise archaeologists had to resort t to the method of relative dating where by comparing with stratigraphically close objects [objects which are buried at the same depth will be approximately of the same era.] clue regarding the time period and historical styles were assumed or rather guesstimated. gsu.edu/hbase/nuclear/cardat.html>15 April 2009.

This data will help the scientists to relationship of Nitrogen-14 and Carbon-14 atom and can be used to predict the age of the artifact directly.

Limitations This method assumes that the ratio of C-14 to C-12 in the atmosphere and in the living organism will be a constant.
