The style of the artefact and its archaeology location stratigraphically are required to arrive at a relative date.

For example, if an artefact, say an oil lamp, is found co-located on the same floor of a governor's dwelling, and that floor can be dated in archaeology terms by reason of the patterns employed in the mosaic, then it is assumed that in relation to the floor that the lamp is of the same age.

Archaeology dating techniques can assure buyers that their item is not a fake by providing scientific reassurance of the artefact's likely age.

Archaeological scientists have two primary ways of telling the age of artefacts and the sites from which they came: relative dating and absolute dating.

When museums and collectors purchase archaeological items for their collections they enter an expensive and potentially deceptive commercial fine arts arena.

Healthy profits are to be made from illicitly plundered ancient sites or selling skillfully made forgeries.

Following this introduction, there are several links to different sites concerning the methods scientists use to assist them in estimating the age of the Earth.

You will investigate Steno's Laws, radiometric dating, and then visit an interactive site that will help you better understand how to tell time - with geology! As you proceed through Assignment 4, be sure to compare your answers from "If Scientists Think. ." to the actual methods scientists use to estimate the age of prehistoric objects.

Relative dating in archaeology presumes the age of an artefact in relation and by comparison, to other objects found in its vicinity.

Limits to relative dating are that it cannot provide an accurate year or a specific date of use.
