Cubic Dice: Archaeological Material for Understanding Historical Processes

The characteristics of dice found in archaeological contexts assist in the understanding of historical processes and human behavior. The dice attributes of configuration and dot pattern are regionally and/or temporally specific and can be used to help date dice themselves or the context in which they are found. As well, dice have been used to decipher Etruscan words and may identify novice and expert dice makers in the archaeological record. The shape and size of the dots and dice cubes further inform the distinctive appearance of dice in medieval versus Roman times

Sex-Ratio, Health, and Social Status: A Biographical Description of Middle and Late Period Bay Area Children

The aim of this paper is to present new information pertaining to the demographic profile of the juvenile burial assemblage (n=39) from a Late Holocene site located on the eastern shore of the San Francisco Bay. CA-ALA-329 is commonly referred to as Ryan Mound and now bears the Muwekma Ohlone name of Mánni Muwékma Kúksú Hóowok Yatiš Túnnešte-tka, which means Place Where the People of the Kúksú (Bighead) Pendants are Buried. This site has been extensively studied and has contributed significantly to our understanding of life on the Bay during the Middle and Late Periods. However, most of the previous studies have focused on adults. The goal of the present study is to identify patterns in the profiles of those who died prematurely, including their sex, their degree of stress experienced based on skeletal indicators of disease/malnutrition, and their social status based on associated grave goods. Results show high incidence of skeletal indicators consistent with nutritional deficiency, disease/infection, and/or metabolic disorder observed in the sample. This suggests that this population was experiencing stress. Individual circumstances, such as age and sex, may also have contributed to poor health because infants have the highest prevalence of cribra orbitalia and periostitis. The distribution of wealth as evidenced by burial goods associated with the sample shows some correlation with age-at-death and the types of artifacts. Distribution of wealth also differs temporally. Inequality seems to have been highest in the Middle Period, while inequality decreased, but overall wealth increased, into the Late Period

Contrasting Male and Female Dietary Life Histories: A Case Study at an Ancestral Muwekma Ohlone Heritage Site in San Jose, California

Stable carbon and nitrogen isotope analyses of bones and teeth at the ancestral heritage Muwekma Ohlone site of Yakmuy ‘Ooyákma-tka (“Place of the East Ridge Site”; CA-SCL-215) reveal significant differences in the dietary life history of males and females. Overall, isotope data indicate that site inhabitants were primarily dependent on low trophic-level foods, likely plants, and minor amounts of marine food for their main source of dietary protein. From tooth dentin serial samples, we found that males were elevated by 0.6-1.0‰ in δ15N in early childhood (age 1-9 years) relative to females, while δ13C values were similar by sex, indicating boys were accessing slightly greater amounts of higher trophic-level foods, such as meat from game. The sex-biased difference in δ15N diminishes during the second decade of life, as female δ15N values increase and become equal to males. However, a difference in δ13C emerges during the second decade where female δ13C values are elevated relative to males. This could indicate that teenage females consumed higher amounts of low trophic-level, marine-derived protein, such as shellfish. During later adult years, the difference in δ13C disappears, while males again show an increase in δ15N relative to females. Although these differences are small, they reveal important sex-biased life history patterns during childhood and adulthood in this ancient community

Overall, isotope data indicate that site inhabitants were primarily dependent on low-trophic-level foods, likely plants, and minor amounts of marine food for their main source of dietary protein. From tooth dentin serial samples, we found that males and females were similar for δ13C in early childhood (age 1–9 years), but boys were elevated in δ15N by 0.6–1.0‰ relative to girls, indicating boys were accessing slightly greater amounts of higher-trophic-level foods, such as meat from game. The sex-biased difference in δ15N diminishes during the second decade of life, as female δ15N values increase and become equal to males. However, a difference in δ13C emerges during the second decade: female δ13C values are elevated relative to males.

Behavioral Modernity and the Cultural Transmission of Structured Information: The Semantic Axelrod Model

Cultural transmission models are coming to the fore in explaining increases in the Paleolithic toolkit richness and diversity. During the later Paleolithic, technologies increase not only in terms of diversity but also in their complexity and interdependence. As Mesoudi and O'Brien (2008) have shown, selection broadly favors social learning of information that is hierarchical and structured, and multiple studies have demonstrated that teaching within a social learning environment can increase fitness. We believe that teaching also provides the scaffolding for transmission of more complex cultural traits. Here, we introduce an extension of the Axelrod (1997} model of cultural differentiation in which traits have prerequisite relationships, and where social learning is dependent upon the ordering of those prerequisites. We examine the resulting structure of cultural repertoires as learning environments range from largely unstructured imitation, to structured teaching of necessary prerequisites, and we find that in combination with individual learning and innovation, high probabilities of teaching prerequisites leads to richer cultural repertoires. Our results point to ways in which we can build more comprehensive explanations of the archaeological record of the Paleolithic as well as other cases of technological change.Comment: 24 pages, 7 figures.

Multidisciplinary investigations of the diets of two post-medieval populations from London using stable isotopes and microdebris analysis

This paper presents the first multi-tissue study of diet in post-medieval London using both the stable light isotope analysis of carbon and nitrogen and analysis of microdebris in dental calculus. Dietary intake was explored over short and long timescales. Bulk bone collagen was analysed from humans from the Queen’s Chapel of the Savoy (QCS) (n = 66) and the St Barnabas/St Mary Abbots (SB) (n = 25). Incremental dentine analysis was performed on the second molar of individual QCS1123 to explore childhood dietary intake. Bulk hair samples (n = 4) were sampled from adults from QCS, and dental calculus was analysed from four other individuals using microscopy. In addition, bone collagen from a total of 46 animals from QCS (n = 11) and the additional site of Prescot Street (n = 35) was analysed, providing the first animal dietary baseline for post-medieval London. Overall, isotopic results suggest a largely C3-based terrestrial diet for both populations, with the exception of QCS1123 who exhibited values consistent with the consumption of C4 food sources throughout childhood and adulthood. The differences exhibited in δ15Ncoll across both populations likely reflect variations in diet due to social class and occupation, with individuals from SB likely representing wealthier individuals consuming larger quantities of animal and marine fish protein. Microdebris analysis results were limited but indicate the consumption of domestic cereals. This paper demonstrates the utility of a multidisciplinary approach to investigate diet across long and short timescales to further our understanding of variations in social status and mobility

Sedentism, storage, and the intensification of small seeds: Prehistoric developments in Owens Valley, California

Many archaeological models describe the development of restricted residential mobility, or sedentism, in prehistoric settings. Sedentism is often part of a suite of cultural changes, often accompanied by seed intensification, storage, population increase, environmental degradation, establishment of social hierarchy, and agriculture. Most models describe these changes as a series of events, with one precipitating the next. As a result, sedentism is interpreted as either a direct byproduct or a causative trigger of other societal changes. Results of excavations at the village site of Sunga'va (CA-INY-3806) are used to examine the timing of sedentism in relation to the development of storage and seed intensification in the Owens Valley of California. The site, which has evidence for two separate occupations from a period that has heretofore not been the subject of intensive research, suggests that sedentism developed at the same time or just before storage and some 800 years before seed intensification. Data do not support social models, such as the activity of aggrandizers or the stabilization of long-distance exchange networks, in these developments
