Fragmentation of archaeological faunal assemblages has served as the basis for inferring a wide range of human behaviors. However, relationships between long bone breakage and past behaviors have often been expressed in terms of a direct equivalence between bone breakage and intensity of processing -- that is, the greater the fragmentation, the more intense the processing. More refined interpretations based on bone breakage require a development of techniques to examine variability within the archaeological record. Data from western North American archaeological sites and several recent Alaskan collections are used as the basis for documentation of assemblage variability in terms of (1) frequencies of complete bones; (2) percentage difference values of proximal and distal articular ends; (3) length of shaft attached to articular ends; and (4) use of ratios of articular ends to shaft splinters and long bone shaft fragments in the development of minimum number of elements counts. -- AATA
