Analyzing cut marks: lessons from artiodactyl remains in the northwestern United States

Analyses and interpretations of the human behavioral significance of frequencies of cut-marked mammal bones have been ongoing for at least 50 years. Many of these studies focus on determining the so-called “butchering pattern.” Few analysts comment on the tremendous range of variation in frequencies and anatomical distributions of cut marks across multiple assemblages of remains of a taxon. Such variation is evident even when faunal remains are associated with technologically, temporally, and environmentally similar cultures. This kind of variation is illustrated with frequencies of cut marked bone specimens comprising major limb joints of two artiodactyl genera from two sites in the northwestern United States. Three hypotheses are tested. The first and second hypotheses (one per genus) predict that the frequencies of cut-marked remains of a taxon from one site will match those frequencies evident on the remains of the same taxon at the other site. Both hypotheses are falsified. The third hypothesis is that remains of the larger taxon at each site will display more cut marks than the remains of the smaller taxon at each site. This hypothesis is statistically falsified at one site but not the other. Refutation of the hypotheses suggests that well-founded interpretations of frequencies of cut-marked remains may require unique kinds of contextual data.
