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.

These strata are often most visible in canyons or gorges which are good sites to find and identify fossils.

CATEGORY: typology DEFINITION: The study of classes with common characteristics; classification of artifacts; the systematic classification of artifacts or remains according to type, i.e. This is the first step in archaeological analysis and necessary in comparing assemblages and in determining time sequences.

Groups of pottery, for example, may be assembled by those with long necks, those with handles, and those with a pedestal base.

It may show increasing complexity or functional improvement, simplification and functional decline, or change based on fashion.

Typology may be associated with chronology, in that it may be possible to place groups of the same kind of material in a sequence.

The most commonly used chronometic method is radiocarbon analysis.

It measures the decay of radioactive carbon (14C) that has been absorbed from the atmosphere by a plant or animal prior to its death.CATEGORY: chronology; technique DEFINITION: Any method used to order time and to place events in the sequence in which they occurred.A sequential ordering that places cultural entities in temporal, and often spatial, distribution.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.This principle presumes that the oldest layer of a stratigraphic sequence will be on the bottom and the most recent, or youngest, will be on the top.
