As an example Pinnacle Point's caves, in the southern coast of South Africa, provided evidence that marine ressources (shellfish) have been regularly exploited by humans as of 170,000 years ago.

The dating methodologies in archaeology are the dating methods used by archaeologists in order to determine the age of ancient materials and deposits remains or determining a chronology or calendar of events in the history of both ancient and recent humans.

Thus, to be considered as archaeological, the remains, objects or artifacts to be dated must be related to human activity.

It is commonly assumed that if the remains or elements to be dated are older than the human species, the disciplines which study them are sciences such geology or paleontology, among some others.

Nevertheless, the range of time within archaeological dating can be enormous compared to the average lifespan of a singular human being.

Dating material drawn from the archaeological record can be made by a direct study of an artifact, or may be deduced by association with materials found in the context the item is drawn from or inferred by its point of discovery in the sequence relative to datable contexts.

Dating is carried out mainly post excavation, but to support good practice, some preliminary dating work called "spot dating" is usually run in tandem with excavation.

Dating is very important in archaeology for constructing models of the past, as it relies on the integrity of dateble objects and samples.

Many disciplines of archaeological science are concerned with dating evidence.

Indirect or relative dating methods tend to use associations built from the archaeological body of knowledge.

An example is seriation, which may use the known style of artefacts such as stone tools or pottery.

Ultimately, relative dating relies on tying into absolute dating with reference to the present.
