Bone surface modification (BSM) remains a primary source of taphonomic inference in paleontological and archaeological contexts. However long-standing debates in BSM studies have undermined the utility of this approach. We use an objective machine-based learning algorithm rooted in Bayesian probability theory designed to quantify the level of uncertainty associated with a formal assignment of agent to individual BSM. Our multivariate Bayesian model, trained on large assemblages of...

For the better part of a century, archaeologists have surmised that beer brewing played a significant role in a range of major social and economic changes having to do with origins of agriculture. This paper examines an unusual case of early beer brewing, which likely originated during the Middle Holocene among the Later Stone Age (LSA) populations of the hyper-arid Central Namib Desert of western Namibia. In this paper, I discuss practices of modern traditional beer brewing in the region and I...

Porridges and beer make up a majority of the household diet throughout much of rural Africa and could possibly be some of the earliest foods produced. In Africa, pottery is one of the primary culinary tools used to make both porridges and beer. This ethnoarchaeological and archaeological research explores pottery using use-alteration and morphological analyses from the Gamo of southern Ethiopia to indicate the use of pottery as a culinary tool. Beer and porridges are considered luxury foods...

Originally excavated in the early 1970s by Beatrice Sandelowsky, the Mirabib Hill Rockshelter is located roughly 250km southwest of Windhoek, Namibia, in the Namib-Naukluft National Park. This poster describes our re-analysis of the lithic technology recovered from Mirabib during the Sandelowsky excavations. The lithics examined in this poster were recovered from the lowest levels of the Sandelowsky excavation, just above bedrock, and date to around 19.5ka. This poster discusses the knapping...

This is an abstract from the "Behavioral Ecology and Archaeology" session, at the 88th annual meeting of the Society for American Archaeology. Madagascar’s southwestern coast has been inhabited by coastal foraging and fishing populations for over a millennium. Despite significant environmental changes in southwest Madagascar’s environment following human settlement, little is known about the scale, pace, and nature of human settlement and subsequent landscape modification. Recent...

The Early Stone Age record is a spatially continuous palimpsest representing thousands of years of artifact discard. The record thus reflects a long-term pattern of hominin movement at a landscape scale. Despite this, most recent research continues to employ interpretive perspectives suited for finer temporal grains and relies on targeted excavation of dense concentrations of artifacts. Here ‘sites’ are investigated as discrete functionally organized places and analytically interpreted based on...

This is an abstract from the "SAA 2021: General Sessions" session, at the 86th annual meeting of the Society for American Archaeology. The Castelo de São Jorge da Mina, better known as Elmina, was established in 1482 in modern-day Ghana by the Portuguese as the first European trading post on the coast of West Africa. The fort was captured by the Dutch in 1637 and remained under Dutch control for the next 235 years. It was transferred to the British in 1872, but, when the local Elmina...

This is an abstract from the "SAA 2023: Individual Abstracts" session, at the 88th annual meeting of the Society for American Archaeology. This project utilizes a biocultural approach to assess the demographics and health of the West African population from Elmina, Ghana. Elmina, selected by the Portuguese in 1482 as the site of the first European trade fort in sub-Saharan Africa, grew from a small coastal fishing village to a large settlement over the course of more than 400 years. This...

Lithic miniaturization, the systematic production and use of small tools from small cores, was a consequential development in Pleistocene lithic technology. Bipolar reduction is an important but often overlooked and misidentified strategy for lithic miniaturization. This experiment addresses the role of axial bipolar reduction in processes of lithic miniaturization. The experiments answer two questions: what benefits does axial bipolar reduction provide, and can we distinguish axial bipolar...

The exposure of the wide continental shelf of the Agulhas Bank during the gradual regression of the shoreline from 45,000 years ago, culminating in the Last Glacial Maximum (LGM), opened up a vast new area for foragers. Humans with well-established coastal resource exploitation strategies would have naturally shifted their foraging range to the south, following the regressing shoreline. During this period, the South African technological record underwent a critical transition from the prepared...

This is an abstract from the "Animal Resources in Experimental Archaeology" session, at the 88th annual meeting of the Society for American Archaeology. Bone has been used as a raw material for a range of activities for at least two million years. The criteria for determining whether a bone was used—or shaped and then used—have been established by archaeologists following decades of experimental research. In contrast, the antiquity of using bone for pressure flaking stone is less well...

This is an abstract from the "African Archaeology throughout the Holocene" session, at the 84th annual meeting of the Society for American Archaeology. Worked bone has a long history across the African continent, occurring as early as the Middle Stone Age in eastern and southern Africa. However, since the beginning of the Holocene, barbed and un-barbed points – associated with the so-called ‘African Aqualithic’ peaking at 9,000 BP – have likewise been recovered from sites within Sahelian and...

This is an abstract from the "Islands around Africa: State-of-the-Art and Future Directions" session, at the 89th annual meeting of the Society for American Archaeology. To help protect the Earth’s diverse species from disappearing at an alarming rate, research is needed in important biodiversity hotspots to understand how humans have interacted with their environment throughout history and how these insights can contribute to their future sustainability. Archaeology and paleoecology are...

Regional social complexity in southern Africa is closely tied to the rise and development of the Mapungubwe polity of 13th century South Africa. Expanding political power and influence meant that Mapungubwe increasingly articulated with communities on its periphery - a relationship that is reflected in shared material culture. These hinterland sites are all located in areas where there is an absence of earlier twelfth century occupation, which suggests a process of active settling of these areas...

The influences of Ethiopia's palaeoenvironments on its past societies may inform land management practices now. A staple for reconstructing palaeoenvironments is to record palaeovegetation changes. Botanical remains for reconstructing palaeovegetation are usually archived in lake sediments. Eastern Tigrai had the most developed ancient civilizations known to sub-Saharan Africa but no lakes. When we began research in Eastern Tigrai, the region had been deforested for so long that botanists...

This is an abstract from the "Recent Advances and Debates in the Pleistocene Archaeology of Africa" session, at the 84th annual meeting of the Society for American Archaeology. Chronometric dating of Late Pleistocene environmental changes and archaeological sites can be refined by correlations with precisely dated volcanic isochrons, stalagmites, and marine isotope stages (MIS). Lake Malawi cores have volcanic ash from the Toba super-eruption, dated ~74 ka at levels previously dated to ~62.5...

Discerning what makes Homo sapiens distinctive among the rest of the species on the planet has been a difficult task. One suggestion has been our use of symbolic culture, the use and transmission of symbols intergenerationally. There is much discussion, however, about who the first ‘symbol users’ were, partly due to debates as to what actually makes something ‘symbolic.’ In this paper, I discus how anthropologists first came to use symbol as the sine qua non of modern human behavior. Then, using...
