Cultural seriations are based on typologies, in which artifacts that are numerous across a wide variety of sites and over time, like pottery or stone tools.If archaeologists know how pottery styles, glazes, and techniques have changed over time they can date sites based on the ratio of different kinds of pottery.Techniques of recovery include: Data collection and analysis is oriented to answer questions of subsistence, mobility or settlement patterns, and economy.Archaeologists like to use several dating methods to find out more about artifacts.
Understanding the geologic history of an area and the different strata is important to interpreting and understanding archaeological findings.
Over many years of research chronologies of stone tools (and pottery) have been built, based on styles (called Seriation).
Archaeologists can also be matchmakers by using the context, which is the where, when and how an artifact is found.
This also works with stone tools which are found abundantly at different sites and across long periods of time.
Stratigraphic dating is based on the principle of depositional superposition of layers of sediments called strata.
