A more precise and accurate archaeology dating system is known as absolute dating and can in most circumstances provide a calendar year to the object.Since 1950 there has been a transformation in the dating techniques of archaeologists.
When museums and collectors purchase archaeological items for their collections they enter an expensive and potentially deceptive commercial fine arts arena.
Radiocarbon dating uses the biological assumption that all living things absorb carbon, both ordinary carbon, C12, and radioactive carbon, C14, into their living tissue.
At the moment of death the C14 begins to decay at a rate that scientists already know from other experiments.
Healthy profits are to be made from illicitly plundered ancient sites or selling skillfully made forgeries.
Archaeology dating techniques can assure buyers that their item is not a fake by providing scientific reassurance of the artefact's likely age.
