Energetic Efficiency and Lithic Technology: An Upper Mississippian Example

Optimal-foraging theory and the concept of energetic efficiency have been used in archaeology for over a decade, usually to explore subsistence behavior. People, however, made choices for energy expenditure in other areas of culture, including lithic technology. It is suggested that a shift in the allocation of energy as an adaptive response to changes in social organization caused the widely noted decline in formal tool types and stone-tool refinement in the late prehistoric periods in eastern North America. Data from an Upper Mississippian village are used to demonstrate the economic use of poor-quality lithic raw material. A bipolar technique was used to produceflake blanks for triangular projectile points as well as a peculiar but common Upper Mississippian tool, the humpback biface. It is suggested that bipolar reduction and other lithic efficiency and economizing strategies are indicators of stress on the energy budgets of human populations.

The potential of bulk δ13C on encrusted cooking residues as independent evidence for regional maize histories

Abstract The histories of maize utilization in eastern North America have been substantially revised recently, primarily because of the analysis of charred cooking residues encrusted on pottery. A multifaceted research strategy of bulk δ13C assays coupled with accelerator mass spectrometry radiocarbon data and microbotanical evidence can yield coherent regional maize use histories. Bulk δ13 C assay interpretation complications include (1) variations among vessels by site, (2) a potential for false negatives, and (3) a wide range of variation potentially present for any given time period. Regional histories using this approach can be quite variable without appropriate use of multiple lines of evidence.

A Multi-Method Approach to Inferring Early Agriculturalists’ Stone Tool Use at the Crescent Bay Hunt Club Site

ABSTRACT While there has been much research on the function of stone tools via use-wear analysis, it is clear that a multipronged approach, including an evaluation of material acquisition, production, and tool use, is necessary if tool function is going to prove truly useful for understanding past cultures. Moreover, the role of chipped lithic tools in the economies of agriculture-based populations has seen little research compared to preagricultural systems. A sample of lithic artifacts from the Crescent Bay Hunt Club site, a twelfth- to fourteenth-century Oneota village at Lake Koshkonong in southeastern Wisconsin, are subjected to a multiple-method analysis to determine individual tool use. An assemblage-based analysis provides an overall understanding of the lithic economy. A combination of microscopic identification of edge damage and surface polishes and an analysis of protein residue provides independent lines of evidence that yield strong inferences about tool use in the lithic economies of sedentary agricultural groups in the midcontinent.

Canine Digging Behavior and Archaeological Implications

Abstract Pit features, frequently reported at archaeological sites, are usually thought be culturally produced. The numbers and forms of pits found at an archaeological site influence inferences of human activity; therefore, the inferred cultural origin of pits at archaeological sites needs to be demonstrated, rather than assumed. Ethnoarchaeological study of dog digging behavior, combined with our understanding of the long symbiotic relationship between human beings and canines, suggests that canine disturbance may be a significant factor in site formation processes. Canines are the probable agent for certain commonly reported pit forms, and are probably implicated in the disturbance of human-dug pits much more often than commonly understood. Dogs dig under a variety of conditions, including those expected in hunter-gatherer, pastoral, and agricultural sites. Excavation of recent dog-holes reveals marked similarities with certain features reported in the archaeological literature.

Sense and Sensibility in Midwestern Archaeology and the Midcontinental Journal of Archaeology, Part I

Abstract The progression of archaeology in the midcontinent over the past 40 years has moved on a series of different but overlapping fronts: regional, governmental, institutional, disciplinary, and personal. This collection of thoughts by both longtime and relatively young practitioners of our field suggests the many ways that archaeology has changed for the good—and maybe not so good—depending on our own experiences. Midcontinental Journal of Archaeology (MCJA) has changed along with these developments. Part I of this discussion centered on the need for, and foundation of, MCJA. Part II is more diverse, with the archaeologists who have participated in the field for the last 40 years reflecting on the shifts in archaeology within their regions—both in terms of practice and institutional practices. The forces of national economics and academic politics and the changing sensibilities toward our public constituencies described here are themes that continue to influence us today.
