Geometric Morphometrics of gold wild boar discovered in the Arzhan-2 tomb, Tuva
In the field of material culture, seriality refers to the serial production of nearly the same object in terms of shape and size, yielding visually identical artefacts. Subtle variations may nevertheless occur, depending on the technologies used, or the number and reliability of moulds, for example. Geometric morphometrics (GM) based on landmark analysis, along with accompanying statistical techniques, provides methods well-suited for identifying small but archaeologically significant variations in shape and size within such datasets. In this study, we exemplify the efficiency of GM in a context of seriality using a large series of centimetric-sized golden wild boars decorating a case for bow and arrows, discovered in the Arzhan-2 barrow of the early Scythian time.
