As an example Pinnacle Point's caves, in the southern coast of South Africa, provided evidence that marine resources (shellfish) have been regularly exploited by humans as of 170,000 years ago.
On the other hand, remains as recent as a hundred years old can also be the target of archaeological dating methods.
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.
It was the case of an 18th-century sloop whose excavation was led in South Carolina (United States) in 1992.
Thus, from the oldest to the youngest, all archaeological sites are likely to be dated by an appropriate method.
There is also dendrochronology, which determines age by the rings present in a tree trunk.
Also, there is the use of index fossils to determine the age of other fossiles.For example, in a stratum presenting difficulties or ambiguities to absolute dating, paleopalynology can be used as a relative referent by means of the study of the pollens found in the stratum.This is admitted because of the simple reason that some botanical species, whether extinct or not, are well known as belonging to a determined position in the scale of time.In this relative dating method, Latin terms ante quem and post quem are usually used to indicate both the oldest and the most recent possible moments when an event occurred or an artifact was left in a stratum.But this method is also useful in many other disciplines.In addition, because of its particular relation with past human presence or past human activity, archaeology uses almost all the dating methods that it shares with the other sciences, but with some particular variations, like the following: Seriation is a relative dating method (see, above, the list of relative dating methods).
