In other words, artifacts found in the upper layers of a site will have been deposited more recently than those found in the lower layers.

Cross-dating of sites, comparing geologic strata at one site with another location and extrapolating the relative ages in that manner, is still an important dating strategy used today, primarily when sites are far too old for absolute dates to have much meaning.

to frequencies of their co-occurrence in specific contexts Ordering of physical remains in a series so that adjacent items in the series are more similar to each other than items farther apart. Relies on principally measuring changes in proportional abundance, or frequency, of ceramic style.

Ordering of artifacts according to their frequencies so that the distribution conforms to a "battleship-shaped" curve.

Chronological dating, or simply dating, is the process of attributing to an object or event a date in the past, allowing such object or event to be located in a previously established chronology.

This usually requires what is commonly known as a "dating method".

Stratigraphy is the oldest of the relative dating methods that archaeologists use to date things.

Stratigraphy is based on the law of superposition--like a layer cake, the lowest layers must have been formed first.

The method drastically reduces the quantity of datable material required.Historians, for example, know that Shakespeare's play Henry V was not written before 1587 because Shakespeare's primary source for writing his play was the second edition of Raphael Holinshed's Chronicles, not published until 1587.Thus, 1587 is the post quem dating of Shakespeare's play Henry V.deposit and can be no alter (no more recent) than the deposit itself Allows to date a field site by dating an artifact because of association Nitrogen, fluorine, uranium, collagen content, gradually reduced by process of chemical decay.

For example, JJA Worsaae used this law to prove the Three Age System.
