Morphology in
archaeology, the study of shapes and forms, and their grouping into period
styles remains a crucial tool, despite modern techniques like
radiocarbon dating, in the identification and dating not only of works of art but all classes of
archaeological artefact, including purely functional ones (ignoring the question of whether purely functional artefacts exist). The term morphology ("study of shapes", from the Greek) is more often used for this. Morphological analyses of many individual artefacts are used to construct
typologies for different types of artefact, and by the technique of
seriation a
relative dating based on shape and style for a site or group of sites is achieved where scientific
absolute dating techniques cannot be used, in particular where only stone, ceramic or metal artefacts or remains are available, which is often the case. That artefacts such as pottery very often survive only in fragments makes precise knowledge of morphology even more necessary, as it is often necessary to identify and date a piece of pottery from only a few
sherds.
