Ways dating artifacts
The underlying principle of stratigraphic analysis in archaeology is that of superposition.
This term means that older artefacts are usually found below younger items.
Archaeology dating techniques can assure buyers that their item is not a fake by providing scientific reassurance of the artefact's likely age.
A submethod within biostratigraphy is faunal association: Sometimes researchers can determine a rough age for a fossil based on established ages of other fauna from the same layer — especially microfauna, which evolve faster, creating shorter spans in the fossil record for each species.
Love-hungry teenagers and archaeologists agree: dating is hard.
But while the difficulties of single life may be intractable, the challenge of determining the age of prehistoric artifacts and fossils is greatly aided by measuring certain radioactive isotopes.
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.
Though still heavily used, relative dating is now augmented by several modern dating techniques.
