Since initial applications of strontium isotope human sourcing in the early 1990s, the use of the method has steadily increased in archaeology and in anthropology more broadly. Despite this trend, the collection of necessary baseline environmental data has not been standardized and sometimes does not occur at all. A thorough environmental sampling strategy will ensure that all the variability within a selected region is documented, which is a critical step to improving the accuracy of sourcing studies. Furthermore, shared strontium baseline data collections are needed to improve the intercomparability of datasets and results. This paper provides a case study from a semiarid region in northwestern New Mexico, USA, highlighting the need for a bottom-up approach to baseline data collection (from bedrock to animal) and describes the methods of pre-field planning and collecting, including rationales for what samples to collect for Sr isotope baseline data. The authors hope that this paper will lay a foundation for the implementation and standardization of Sr isotope baseline data collecting, which does not currently exist.

A number of researchers have shown that the abundance, diversity, and size of prey consumed or displayed at a feast can be used by elites to solidify and/or aggrandize their social position. Expectations for archaeological signatures of elite feasting—derived from ethnographic studies, archaeological research, and ecological theory—are used to assess the archaeofaunal record from selected contexts of the Marana platform mound site, located in southern Arizona. The magnitude of work conducted in the region provides a unique opportunity to address the importance of feasting as a mechanism of power consolidation among Hohokam elites. Here, we examine a hypothesized locus of elite feasting among the Classic period Hohokam (ca. A.D. 1250). A relatively high concentration of animal bone derived from a burned room adjacent to the Marana platform mound was first thought to represent debris from elite feasting. Analysis reveals a proportionate taxonomic profile that is similar to the remainder of the community and an overwhelming abundance of small game relative to large prey. Neither situation is consistent with elite feasting expectations. These results argue for a form of feasting among non-elites that likely served to promote intragroup solidarity or political support within the community.

Previous research on the prehistoric communities of Chaco Canyon, New Mexico (ca. A.D. 800–1250) provides evidence of an extensive procurement system of nonlocal food and economic goods. In this paper, we use oxygen and strontium isotope analyses to establish whether animal protein followed a similar pattern. We contextualized our isotopic analyses of the archaeofaunas from recent excavations at Pueblo Bonito with data on modern faunas across an area of approximately 100,000 km2 around the site. Our results show that most archaeological deer, rabbits, and prairie dogs were obtained from >40 km away from Pueblo Bonito with the latter two likely being garden hunted. The Chuska Mountains west of Chaco Canyon and more distant San Juan Mountains to the north were the main source areas. These results closely align with previous results on architectural wood, corn, and other key resources. The importation of small game animals suggests that the local supplies could not meet the needs of the community. Long‐distance meat procurement may have been embedded within a more complex network of ritual‐goods exchange or tribute that helped to offset the transport costs. Resource depletion may have contributed to the eventual abandonment of the region during the Medieval Warm Period.
