Glorioso Islands (Country) (Geographic Keyword)
301-325 (579 Records)
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. The Zambezian Ecozone of east-central Africa comprises faunal communities that include elements from both southern and eastern Africa. The region has long served as an important crossroads for faunal exchange, but its timing and implications for hunter-gatherer behavior are unknown. Late Pleistocene faunal assemblages...
Late Pleistocene Occupation in the Southern Kalahari: New Results from the North of Kuruman Palaeoarchaeology Project (2021)
This is an abstract from the "From Veld to Coast: Diverse Landscape Use by Hunter-Gatherers in Southern Africa from the Late Pleistocene to the Holocene" session, at the 86th annual meeting of the Society for American Archaeology. Recent investigations of the southern African Late Pleistocene archaeological record have transformed our understanding of the biocultural evolution of our species. Although the intensity of research on coastal and near-coastal records is greater than in the...
A Late Pleistocene Palaeoenvironmental Record for Northern Namaqualand, South Africa: Geoarchaeology, Geochronology, and Stable Isotopes from Spitzkloof A Rockshelter (2024)
This is an abstract from the "SAA 2024: Individual Abstracts" session, at the 89th annual meeting of the Society for American Archaeology. Excavations at Spitzkloof A Rockshelter, northern Namaqualand, South Africa, identified a deep stratified sequence with pulsed occupation dating to the Last Glacial Maximum (23–17 kcal. BP) and Marine Isotope Stage 3 (>51 ka BP), while the lowest layers are candidates for U-series dating. Importantly, this period encompasses a time of marked climate...
The Later Stone Age in the 4th Cataract Region, Sudan: Lithic Assemblage Features at ASU 09-02 (2017)
Later Stone Age (LSA) foragers in the Middle Nile Valley had relatively mobile lifeways that included use of pottery. Distinguishing LSA from Neolithic ceramics is difficult due to continuity in styles, an issue that extends to lithic assemblages. Lunate microliths and scaled pieces and use of flint and quartz as main lithic raw materials span both periods. We examine the lithic assemblage at ASU 09-02, a LSA site in the 4th Cataract region of northern Sudan. Situated on a terrace north of the...
Learning From Scratch What The Environments Were Like As The Complexities Of Societies Changed In Eastern Tigrai (2017)
Home to Aksum and other highly-developed polities, the Tigrai Plateau is a leading contender for sub-Saharan Africa's richest center of ancient state formation. This and its susceptibility to environmental (climate and land cover) variation make the region compelling for evaluating whether environmental changes affected the trajectories of polities. Soils exposed by gullying are the longest continuous archives of environmental proxies in the region. Many proxies are affected by both climate and...
Least-Effort Knapping as a Baseline to Study Social Transmission in the Early Stone Age (2023)
This is an abstract from the "SAA 2023: Individual Abstracts" session, at the 88th annual meeting of the Society for American Archaeology. Variation in lithics has been used as a mechanism to infer diachronic aspects of hominin behavior. The emergence of the Acheulean industry is considered a major milestone in the evolution of hominin cognition. This perspective is predicated on the idea that Acheulean large cutting tools (LCTs) require mental templates imposed through knapping and that LCTs...
The Legacy of the Foraging Spectrum and Mikea Ethnography: Do We Need Hunter-Gatherer Studies Anymore? (2024)
This is an abstract from the "Three Sides of a Career: Papers in Honor of Robert L. Kelly" session, at the 89th annual meeting of the Society for American Archaeology. One way to view the twentieth-century history of hunter-gatherer studies is as a long attempt to evaluate Victorian notions of foragers as primitive relics with actual data from real foraging peoples. This history came to a fiery climax during the Kalahari history debate of the 1990s, when researchers argued whether...
Levallois, Learning, and Lithic Variation: Results from Porcelain Flintknapping Experiments (2018)
The ability to transmit cultural information with high-fidelity across generations is a defining trait of modern humans. It is unclear, however, how and when this adaptation emerged in the human lineage. The earliest forms of human technology—stone artifacts—required knappers to understand raw material mechanics, as well as geometry (volume reduction, angles), and physics. Thus, it is often assumed that the spread of lithic technologies involved some degree of information transmission. However,...
Life in the Margins: The Pre-Still Bay Deposits from Varsche Rivier 003, Southern Namaqualand, South Africa (2021)
This is an abstract from the "From Veld to Coast: Diverse Landscape Use by Hunter-Gatherers in Southern Africa from the Late Pleistocene to the Holocene" session, at the 86th annual meeting of the Society for American Archaeology. Varsche Rivier (VR) 003 is located in the Knersvlakte, the quartz-gravel plains of southern Namaqualand, South Africa. While currently a marginal, low-rainfall region within the Succulent Karoo Biome, conditions were more favorable during the Late Pleistocene....
Life in times of change – A bioarchaeological perspective on health and living conditions in Upper Nubia in the late 2nd and early 1st millennium BC (2017)
With the end of the Pharaonic Egyptian colonial occupation c. 1070BC and the increasing deterioration of climatic conditions, communities in Upper Nubia faced significant changes, both to the political structure (which may have affected trade networks), and to the agricultural potential of the region (e.g. availability of arable land). This presentation aims to elucidate if, and in what ways, these alterations impacted upon the living conditions of the people in the area, using the skeletal...
Lithic Analysis of an Early Later Stone Assemblage at Malony’s Kloof, a Rock Shelter in the Northern Cape Province of South Africa (2019)
This is an abstract from the "SAA 2019: General Sessions" session, at the 84th annual meeting of the Society for American Archaeology. Temporal organization systems which separate lithic artifacts into designations based on age, geographic area and technology are vital in order to operationalize archaeological information and allow for researchers to make their findings transferable and reproducible. Each Stone Age has characteristics that allow researchers to designate technologies...
Lithic Analysis of GaJj17: a Middle Stone Age Locality in Koobi Fora, northern Kenya (2017)
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 Attribute Analysis for Blydefontein Backed Blades and Endscrapers (2024)
This is an abstract from the "SAA 2024: Individual Abstracts" session, at the 89th annual meeting of the Society for American Archaeology. Attribute analyses are common in the field of archaeology for categorizing and analyzing artifacts. In this study, the Later Stone Age end scrapers and backed blades from Blydefontein Rock Shelter in South Africa undergo an attribute analysis using an objective attribute guide. The guide combines common terms from previous studies along with new terms for...
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...
Local Responses to Global Events: Regionally Distinct Dietary Changes among Eastern African Herders at the Close of the African Humid Period (2018)
Changing human diets in eastern Africa across the end of the African Humid Period (AHP) have been inferred indirectly from cultural and faunal remains at archaeological sites. Stable isotope analysis (SIA, specifically δ13C) can measure diets directly, yet few studies have conducted SIA on human remains from this region. We present 25 new δ13C values from human tooth enamel recovered from archaeological sites around Lake Turkana (northwest Kenya) and on Lukenya Hill and Rigo Cave (southern...
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...
Long-Term Settlement in Plantation Regions of Unguja, Zanzibar (2021)
This is an abstract from the "SAA 2021: General Sessions" session, at the 86th annual meeting of the Society for American Archaeology. In this paper, I discuss the results of an archaeological survey conducted in 2019 in north-central Unguja, Zanzibar. The aim of the survey was to investigate the long-term settlement history of regions that were transformed in the nineteenth century by Omani landowners who developed an agricultural export economy using a labor force of enslaved East Africans....
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...
Low-Cost Centripetal Technology in the LSA of Southern Mozambique (2024)
This is an abstract from the "Expedient Technological Behavior: Global Perspectives and Future Directions" session, at the 89th annual meeting of the Society for American Archaeology. Centripetal lithic technology, including various forms of Levallois technique, is very common in the African MSA. This technology is commonly identified by prepared core technology, where striking platforms are fully prepared to produce a variety of blanks. In Mozambique, both Levallois and prepared discoidal...
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...
Macrobotanical and Microbotanical Evidence for Plant Use and Consumption at Gede, Kenya (2024)
This is an abstract from the "SAA 2024: Individual Abstracts" session, at the 89th annual meeting of the Society for American Archaeology. Over the last several decades, excavations at numerous Swahili period sites along the East African coast have yielded a wide variety of data on economic and cultural practices during the last millennium BP. The results of intensive flotation recovery of macrobotanical remains from pit latrine sediments at housing structures are presented, providing direct...
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...
