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.Love-hungry teenagers and archaeologists agree: dating is hard.But while the difficulties of single life may be intractable, the challenge of determining the age of prehistoric artifacts and fossils is greatly aided by measuring certain radioactive isotopes.These techniques both place assemblages of artefacts into relative order.Petrie used sequence dating to work back from the earliest historical phases of Egypt into pre-dynastic Neolithic times, using groups of contemporary artefacts deposited together at a single time in graves.Though still heavily used, relative dating is now augmented by several modern dating techniques.

Green plants absorb the carbon dioxide, so the population of carbon-14 molecules is continually replenished until the plant dies.Relative dating methods allow one to determine if an object is earlier than, later than, or contemporary with some other object.It does not, however, allow one to independently assign an accurate estimation of the age of an object as expressed in years.It must be made clear at the outset that typology is not, strictly speaking, a dating method, but a means of placing artefacts into some kind of order.Classification divides things up for the purposes of description, whereas typology seeks to identify and analyse changes that will allow artefacts to be placed into sequences.
