The Koobi Fora region in eastern Turkana, northern Kenya, is known for its preservation of Plio-Pleistocene hominin fossils. However very little is known about the Middle Stone Age (MSA) from this region. Fossil and genetic evidence suggest modern humans originated in eastern Africa ~200ka, adding to the significance of this time period and region. In 2016, we excavated site GaJj17, an MSA site located in Area 104 of Koobi Fora. Here we present lithic analysis of recovered in situ and surface...
Lithic artifact production at the Large-scale Pharaonic chert quarries of Wadi el-Sheikh, Egypt (2017)
Recent research into quarrying and lithic production in Wadi el-Sheikh, Egypt by the University of Vienna has identified activities extending from the Middle Paleolithic to modern times. These include Middle Paleolithic use of surface materials, Neolithic chert quarrying, Pharaonic gypsum extraction, quarrying and production of groundstone, ochre collection, and small-scale independent modern salt quarrying. However, the most striking activities are the large-scale Pharaonic period chert...
Lithic Miniaturization and Behavioral Variability in Southernmost Africa 18–11 kcal. BP (2018)
Lithic miniaturization, the systematic production of small stone artifacts by controlled fracture, was a pervasive feature of late Pleistocene lithic technology. Smaller toolkits enabled humans to exploit raw materials more efficiently, to produce composite tools more effectively, to reduce a wider range of rocks, and to increase mobility by lightening toolkits. These benefits allowed humans to occupy a wider range of ecological niches. Archaeologists working in southern Africa have long...
Lithic Taphonomy and Digital Hydrogeologic Models: A GIS Based Approach to Understanding the Formational History of Surface Assemblages (2018)
Surface assemblages play an important role in understanding human behavior. However, modern erosional processes—specifically flowing water—can limit the behavioral inferences that can be gained from surface assemblages by transporting materials from their original discard sites. The influence of these processes can be observed in the size distribution and condition of surface lithic assemblages. The topography and geomorphology of the landscape heavily dictates the degree to which fluvial...
The Location for the Origin of Domesticated Sorghum in Africa: A Brief Review of Some Cultures in the Sahara, Nile, and Sahel (2023)
This is an abstract from the "Subsistence Crops and Animals as a Proxy for Human Cultural Practice" session, at the 88th annual meeting of the Society for American Archaeology. Recent analyses have established the location for the origin of domesticated sorghum occurring in the far eastern Sahel of Sudan during the fourth millennium BC associated with the Late Neolithic Butana Group. For over a half century, sorghum domestication has been hypothesized as occurring somewhere in the Sahelian...
Longevity and authority in a mobile world the megasites of the Ugandan grasslands (2017)
Much of the recent past of Great Lakes Africa is characterised by short-lived settlements and mobile societies, that produced ephemeral occupation sites. In part because of this, attention has long been drawn to sites like Bigo and Ntuusi which seem to offer much more substantive archaeological remains. Yet, notwithstanding the longevity of the latter and the extent of both, this is clearly not a simple occupation site featuring a large population. Rather it is much more effective to understand...
Luminescence Age Calculation Models, Termites, and Dune History in the Northern Kalahari Desert, Hwange National Park, Zimbabwe (2023)
This is an abstract from the "A Tribute to the Contributions of Lawrence C. Todd to World Prehistory" session, at the 88th annual meeting of the Society for American Archaeology. Archaeologists often accept optically stimulated luminescence (OSL) ages with less critical review than those derived from the more commonly used radiocarbon dating methods. This is largely because of an incomplete understanding of optical dating techniques and the modeling assumptions used to calculate these ages....
Macro- and Microscopic Effects of Heating in Lithics: Potential Indicators of Human-Controlled Fire? (2018)
Outside of clear association of human activities and fire features (e.g., a constructed hearth and artifacts), a perennial challenge persists in linking human/hominin behavior to the control of fire. This particularly vexes ongoing investigations to determine early human-fire interaction(s). Although natural landscape fires can be intense, their tendency to move quickly may limit modifications in lithic material at ground level. Studies examining the effect(s) of heating tool-stone at different...
Mai Adrasha and Its Neighbors (2017)
A team from UCLA in cooperation with the Tigrai Culture and Tourism Agency and the Authority for Research and Conservation of Cultural Heritage of Ethiopia has completed two excavation seasons at the site of Mai Adrasha located about 70 kilometers west of the ancient capital of Aksum. With the information gathered in these excavations, we can now begin to compare Mai Adrasha to neighboring sites and place it within its regional framework. Radiocarbon dates from the first season of excavation...

The Many Meanings of Red: Ochre Use through Time in Southern Africa (2019)
This is an abstract from the "Culturing the Body: Prehistoric Perspectives on Identity and Sociality" session, at the 84th annual meeting of the Society for American Archaeology. From c.100 000 years ago, ochre pieces were habitually collected and used at Middle Stone Age sites in southern Africa. This earthy iron-rich rock has been continually used since then and still has many applications today, such as pigment, sunscreen or body paint for ritual purposes. Although a range of colors were...
Mapping MSA Deposits: Regional Geological Investigation of Upper Chari Member Sediments in the Ileret Region, East Turkana, Kenya (2017)
The Ileret region of the Koobi Fora Formation (KF Fm.), located in Kenya’s Turkana Basin, has historically been the focus of extensive archaeological research. Mid-Late Pleistocene units have previously lacked defined sedimentary beds due to an understudied unconformity of the upper Chari Member (1.34 Ma to 10 Ka). This represents a substantial limit to Middle Stone Age (MSA) research. Recent fieldwork (2016) incorporated a geoarchaeological survey of the upper Chari Member. Here we describe and...
Material elaboration and monumentality: Mortuary beads, pastoralists, and social innovation in northwest Kenya (2017)
Megalithic architecture appeared suddenly in northwest Kenya 5000 years ago in tandem with the earliest pastoralists in the region. As Lake Turkana’s levels dropped, these people built "pillar sites" – massive feats of labor and coordination that represent one of the earliest instances of monumentality in Africa – in a brief explosion of material and architectural elaboration. The burials associated with these pillar sites are highly ornamented, with thousands of beads made from stone, bone, and...

The Medieval Necropolis of Mouweis (Shendi Area, Sudan): Bioarchaeological Insights (2017)
The site of Mouweis is a Nilotic city of the Meroitic period excavated by the Louvre Museum since 2007. This settlement includes a 1st century AD palace, later destroyed and reduced to a hill-shaped ruin. During the medieval period, a cemetery was created in the demolition level of this palace. Radiocarbon dating reveals a funerary occupation between of the 8th to the 14th century. Burials were mainly individual with a uniform typology and follow the same orientation as the structure of the...
Microremains on Stone (Tools): Discriminating Function-Related from Natural Residues (2019)
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. Plant microremains from stone tools speak to ancient hominin behaviour if genuinely related to usage. Residues, however, attach to rock surfaces naturally. My objectives are to identify pathways for microremain adherence prior to and after burial; study residue abundance in relation to petrography, microstructure, and...
A Middle and Later Stone Age sequence from Iringa, southern Tanzania (2017)
Magubike rockshelter in the southern Highlands of Tanzania contains a long archaeological sequence ranging from the Middle Stone Age (MSA) through historic times. This paper describes the lithic sequence from test pit 5, which contains a 2.5 m thick cultural deposit composed of recent / historic remains, an Iron Age, a microlithic Later Stone Age (LSA), a macrolithic LSA, a transitional sequence from the MSA to the LSA and 90 cm of MSA artifacts. The later part of the sequence replicates the...
The Middle Stone Age at Gona, Afar, Ethiopia: Implications for Regionalization and Migrations (2019)
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. Tentatively dated to MIS 5/4, the YAS-1 (Ya’alu South 1) site at Gona, Ethiopia is a high-density open-air archaeological site preserving classic Middle Stone Age (MSA) stone tools such as Levallois cores, Nubian cores, points, and blades in addition to a variety of fossil fauna, some with bone modifications including...

(Mis-) Reading Land: Early Portuguese Settlement on Cape Verde (2017)
This paper considers the early Portuguese settlement on Santiago Island, Cape Verde. Particularly focussing upon the towns of Cidade Velha and Alcatrazes, their immediate topographic settings clearly contributed to the long-term success of the former and the failure of the latter. Nonetheless, the results of a decade of excavation at Cidade Velha demonstrates how long it took for the colonisers to actually understand the landscape’s environmental dynamics, especially the impact of seasonal...
A Model of the Extinct Palaeo-Agulhas Plain Ecosystem in Southernmost Africa (2019)
This is an abstract from the "Human Interactions with Extinct Fauna" session, at the 84th annual meeting of the Society for American Archaeology. Unlike some regions, Africa was not subject to massive and abrupt mammalian extinction events in the Late Quaternary, but some African regions were subject to abrupt extinctions of small numbers of species. The coast of South Africa records such an extinction event near the Pleistocene and Holocene boundary. These extinct species were all adapted to...
Modeling Human-Environment Interaction in Sub-Saharan Africa: Archaeological Data, Ecological Questions (2017)
The African Iron Age transition is characterized by a shift from nomadic hunting and gathering societies to food-production, ferrous metallurgy, and centralized states and empires across most of the continent. Because of the magnitude and persistence of the change, understanding the African Iron Age is critical for assessing the present state and potential future of Africa’s ecosystems. Because the transition occurred episodically and at different times in different regions, and because large...
Modeling Mobility and Lithic Raw Material Transport in the Late Pleistocene along the Southern Coast of South Africa (2023)
This is an abstract from the "Adventures in Spatial Archaeometry: A Survey of Recent High-Resolution Survey and Measurement Applications" session, at the 88th annual meeting of the Society for American Archaeology. Understanding how hunter-gatherer groups move around the landscape is essential for answering questions about human behavioral ecology and evolution of the social landscape. Lithic raw material proveniencing sheds light on how far people in the past were traveling for toolstone and...
More Than Just Pretty Things: Taphonomic and Behavioral Observations from the Unworked Ostrich Eggshell Assemblage Recovered from Grassridge Rockshelter, South Africa (2021)
This is an abstract from the "Current Zooarchaeology: New and Ongoing Approaches" session, at the 86th annual meeting of the Society for American Archaeology. Grassridge Rockshelter demonstrates one of the largest assemblages of ostrich eggshell beads and preforms in southern Africa that dates to the mid-Holocene. The site, located in the interior of the Eastern Cape of South Africa, therefore reflects an intensive use of ostrich eggshell as a raw material source for the production of...
Mortuary Practices of Later Stone Age Hunter-Gatherers in Northern Malawi (2021)
This is an abstract from the "Human Origins Migration and Evolution Research Consortium Poster Symposium" session, at the 86th annual meeting of the Society for American Archaeology. Later Stone Age (LSA) hunter-gatherer mortuary practices are poorly understood in south-central Africa. Tropical climate and acidic soils hinder preservation, bioturbation is prevalent, and research coverage is sparse. The site of Hora 1, in the Mzimba District of Malawi, provides a rare opportunity to examine...
