Anthropological research has long theorized that emergent food-producing economies catalyzed high levels of inequality in human societies, as evident in the earliest use of jewelry made from gold, copper, and other precious minerals among early agricultural populations. Although the US Southwest appears to have been an exception, we report the discovery of two Basketmaker II period necklaces constructed of green iridescent scarab beetle femora, which suggests a homologous association between emergent agriculture and inequality. Drawing insight from ethnography, archaeology, entomology, and evolutionary ecology, we hypothesize that these and other jewelry items of Basketmaker II culture were visually prominent, honest signals of socioeconomic capital that emerged during a period of surplus food production and incipient wealth accumulation. It appears that Basketmaker II societies—like other emergent food-producing economies around the world—grappled with the opportunities and challenges that arise with surplus production, albeit in a distinct way that involved visually striking insect and feather adornments as status signals. Archaeologists may have previously overlooked this behavior due to Western biases that privilege precious metals and minerals as prestige objects and archaeological biases that tend to view insects as food or agents of site disturbance.

Plants and animals play a vital role in the human experience, from providing basic sustenance to creating unique social practices that may govern familial, political, or religious experiences; reconstitute identities; or forge social relationships. In this article, we present analyses on the ethnobotanical and zoological remains recently recovered from the Spring Lake Tract, Cahokia, a neighborhood populated from approximately AD 900 to 1275. The assemblage represents a variety of plants and animals that demonstrate the diverse utility of the biota from the region. We conclude that this assemblage indicates that this neighborhood community participated in an array of practices not easily dichotomized into “ritual” or “domestic.” From the perspectives of “Place-Thought” and locality, we emphasize the agency of these entities (plant/animal/human) in the process of creating and sustaining this Cahokian neighborhood.

In the US Southwest and Northwest Mexico, people and turkeys (Meleagris gallopavo) have had a reciprocal relationship for millennia; turkeys supplied feathers, meat, and other resources, whereas people provided food, shelter, and care. To investigate how turkeys fit within subsistence, economic production, sociopolitical organization, and religious and ritual practice in the Mimbres Valley of southwestern New Mexico, we report on genetic (mtDNA) and stable isotope (δ13C, δ15N) data from turkeys recovered from Mimbres Classic period (AD 1000–1130) sites. Results indicate that Mimbres aviculturists had haplogroup H1 and H2 turkeys, and most ate maize-based diets similar to humans, but some ate nonmaize and mixed diets. We contextualize these data to other turkey studies from the northern Southwest and discuss how the human-turkey relationship began, the evidence for pens and restricting turkey movement, and the socioecological factors related to turkey management during the Classic period, particularly the challenges associated with providing maize to turkeys during times of environmental stress. This study has broad relevance to places where people managed wild, tame, and domestic animals, and we offer new insights into how prehispanic, small-scale, middle-range agricultural societies managed turkeys for ritual and utilitarian purposes.

Radiocarbon dates on marine shell and other materials of marine origin appear significantly older than contemporaneous samples of terrestrial/atmospheric origin. Misunderstandings regarding the mechanisms that give rise to this “marine reservoir effect” (MRE), the terminology used to define it, and the mathematics used to describe it cause many coastal archaeologists to distrust or misinterpret marine shell dates. The recent release of a reformulated 14C calibration curve for marine samples (Marine20), which necessitates recalculation of all local reservoir age corrections, may add to the confusion. Here, we review the benefits of dating shell; provide a plain-language explanation of the mechanical, chemical, biological, and cultural processes that give rise to age disparities associated with the MRE; and offer advice to archaeologists intending to date marine shell. Our hope is that these comments will not only aid archaeologists in the planning and interpretive stages of research but also assist in assessing the reliability of legacy chronologies based on marine materials. More broadly, we encourage careful evaluation of all sources of uncertainty in all 14C chronologies, whether based on terrestrial or marine materials.

Recent investigations of Morton Village, a Mississippian and Oneota community formed following Oneota migration into the central Illinois River valley around AD 1300, focus on evaluating the social context for the remarkable violence evidenced at the adjacent Norris Farms 36 cemetery. Here, we use the concepts of thirdspace and hybridity to examine three areas of village life: creation of the physical structure of the village, ritual, and foodways. Within these three areas, we identify transformations of Mississippian and Oneota practices that support the interpretation that villagers were engaged in the formation of a coalescent community.

Drills and projectile points from a site often share a similar shaped base, and it is typically assumed that these drills are reworked hafted points. Measurements of triangular-shaped drills and triangular arrow points from an Iroquoian site indicate that, on average, these drills had narrower bases and were thicker than points. Additionally, most preserved point foreshafts from the western United States are too short if used as a simple drill shaft, and most dart and arrow shafts are too long to serve as convenient drill shafts if used with a strap or bow drill. These data call into question the assumption that drills were reworked hafted points at Iroquoian and possibly other sites.
