New data from Toumboura III site, eastern Senegal, dated between 40 ± 3 and 30 ± 3 ka, point towards the use of ochre pieces as part of an occasional and specialized ochre crushing activity, probably dedicated to the production of powders, as well as the use of ochre sticks. Ochre pieces were studied at both macro and microscopic levels and while some of this iron-rich material likely accumulated in the deposits without anthropogenic intervention, another significant set of ochre pieces was found that was likely processed <em>in situ</em>. The impact scars on the pieces are not as striking as grinding traces for evidencing human exploitation. Nonetheless, they cannot be explained by natural phenomena. These remains could represent the earliest known evidence of ochre exploitation in Senegal. They potentially open new perspectives on symbolic behaviours in the Middle Stone Age of West Africa.

These data are consistent with the consumption of larger quantities of anthropogenic food waste including carrion from scavengers and slaughtered and farmed livestock animals, which is reduced in volume in today's landscapes.

Traditionally, the answers to these questions were sought by identifying compositional averages and by studying their correlations with either the geochemical signatures of candidate raw material sources or the corresponding physical or chemical properties of the studied materials. However useful, this approach only exploits part of the potential information locked inside the chemical compositions of archaeological artefacts. We argue that different levels of compositional dispersion observed within and across archaeological assemblages, and in particular changes in them as a function of behaviourally meaningful factors (such as the size, function, or recovery location of the objects), are sources of information in themselves. To gain probabilistic insights into both types of variability (averages and dispersions) simultaneously, we introduce variable dispersion beta regression models for the archaeological sciences. In doing so, we show how adopting the beta distribution provides a significantly improved alternative to previous solutions to modelling compositional data within the field — namely, those involving simple linear regression on log-transformed data. These approaches often result in numerically impossible predictions, whilst beta regression restricts the model predictions between the upper and lower compositional bounds, accounts for the inherently inconsistent variances of compositional data, and explicitly permits the modelling of compositional dispersions as a function of covariates. Finally, we expand upon this toolset by showing how using a hierarchical model specification within the framework accounts for both local variation and more widely shared practices of material processing and procurement concurrently, and alleviates issues to do with sampling uncertainty. We demonstrate the proposed approach with a study of Muisca gold procurement practices (AD 600–1600) in the Eastern Highlands of Colombia, based on a dataset of 243 elemental analyses. The results allow us to argue for intra-regional movements of fresh geological gold imported from a variety of distant sources. We suggest these movements could result from contributions of gold by people converging into the same location for festivities. The approaches taken to modelling compositional data are readily applicable to other sub-disciplines of the archaeological sciences, such as compositional studies of ceramics and glass, or modelling the variability of diets in isotopic studies (see Supplementary Material S0 for an extended summary in Spanish).</div></div>","PeriodicalId":50254,"journal":{"name":"Journal of Archaeological Science","volume":"173 ","pages":"Article 106106"},"PeriodicalIF":2.6,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142825120","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Commonly, each pathway is present in an assemblage, although typically pathway 1 beads are more frequent. What is not clear are the reasons that both production strategies exist, if one pathway presents more advantages than the other or if there are social or other reasons for following one strategy over the other. In this study we experimentally create OES beads using these two pathways to determine if one pathway has benefits over the other. We also test if heat treatment has either advantageous or disadvantageous influences on OES bead creation. We look at OES bead technology found at Little Muck Shelter, where both pathways are present, to determine if our experimental findings are reflected in the archaeology. The results show that there are many ways to manufacture OES beads and that both pathways 1 and 2, as well as heat treatment of shell, has advantages and disadvantages. Neither pathway offered a faster manufacturing method for bulk production, but pathway 2 did yield a vaguely higher success rate. Heat treatment of shell did aid the process in making the drilling and trimming of beads slightly faster but was less often used at LMS.

Physiology dampens this variability, however, as oxygen passes from environmental sources into blood and forming teeth. We showcase two methods of high resolution, 2-dimensional enamel sampling, and conduct modeling, to report why and how environmental oxygen isotope variability is reduced in animal bodies and teeth. First, using two modern experimental sheep, we introduce a sampling method, die-saw dicing, that provides high-resolution physical samples (n = 109 and 111 sample locations per tooth) for use in conventional stable isotope and molecular measurement protocols. Second, we use an ion microprobe to sample innermost enamel in an experimental sheep (n = 156 measurements), and in a Pleistocene orangutan (n = 176 measurements). Synchrotron and conventional μCT scans reveal innermost enamel thicknesses averaging 18 and 21 μm in width. Experimental data in sheep show that compared to drinking water, oxygen isotope variability in blood is reduced to 70–90 %; inner and innermost enamel retain between 36 and 48 % of likely drinking water stable isotope range, but this recovery declines to 28–34 % in outer enamel. 2D isotope sampling suggests that declines in isotopic variability, and shifted isotopic oscillations throughout enamel, result from the angle of secretory hydroxyapatite deposition and its overprinting by maturation. This overprinting occurs at all locations including innermost enamel, and is greatest in outer enamel. These findings confirm that all regions of enamel undergo maturation to varying degrees and confirm that inner and innermost enamel preserve more environmental variability than other regions. We further show how the resolution of isotope sampling — not only the spatial resolution within teeth, but also the temporal resolution of water in the environment — impacts our estimate of how much variation teeth recover from the environment. We suggest inverse methods, or multiplication by standard factors determined by ecology, taxon, and sampling strategy, to reconstruct the full scale of seasonal environmental variability. We advocate for combined inverse modeling and high-resolution sampling informed by the spatiotemporal pattern of enamel formation, and at the inner or innermost enamel when possible, to recover seasonal records from teeth.</div></div>","PeriodicalId":50254,"journal":{"name":"Journal of Archaeological Science","volume":"175 ","pages":"Article 106148"},"PeriodicalIF":2.6,"publicationDate":"2024-12-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142902010","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
