Dating methods used in archaeology
An aspect of a site that is only horizontal, such as a road, is not a feature.
An example is a frequently used fire ring will leave evidence behind in the soil, but it cannot be moved with the occupants.
The artifacts are taken to a lab, either locally or at the archaeologists home institution.In Egyptology the method was first used by Petrie for dating the Naqada period, from the development of the so-called wavy-handled pottery.- At least some objects belonging to such a typology should be datable by other criteria to fix a typology into a chronological framework. An object category or motif might develop not regularly but in staccato 'jumps'.They start by setting up a grid and connecting the grid to a datum. They carefully remove dirt and note the precise location of any artifacts found.A datum is a fixed reference point, often one placed by the U. The context of the artifact is just as important as the artifact itself, so the artifacts are always carefully mapped and documented.
