Carbon dating is a technique used to determine the approximate age of once-living materials.

By comparing the placement of objects with the age of the rock and silt layers in which they were found, scientists could usually make a general estimate of their age. However, many objects were found in caves, frozen in ice , or in other areas whose ages were not known; in these cases, it was clear that a method for dating the actual object was necessary.
