In terms of artefacts present, West Africa is not short of evidence relating to human occupation during the Quaternary. The problem hitherto has been one of context and dating; there has been some progress in this regard but poor preservation conditions still restrict the presence of organic remains prior to the beginning of the Late Stone Age (LSA). Nonetheless, an excellent climatic record for the last 520 kya has been established on the basis of cores obtained from Lake Bosumtwi. Stratified Acheulean sites have been excavated at Sansandé and Ravin Blanc on the Falémé River in eastern Senegal. The succeeding Sangoan is an entity for which a consistent and reliable classification remains to be achieved. Despite this, excavations at Anyama in the Ivory Coast have produced a sizeable quantity of material, with a terminus post quem thermoluminescence (TL) date of 254 ± 51 kya. Our knowledge of the Middle Stone Age (MSA) has been transformed by the work carried out at Ounjougou in Mali. More than twenty-five distinct archaeological occurrences have been detected, extending from about 75 to 25 kya. The MSA elsewhere is abundant, and at Adrar Bous is in place beneath the Aterian, but much of it lacks a good stratigraphic context. The following dry period, the Ogolian, must have had a dramatic effect on human settlement, and the majority of LSA sites postdate this episode. There is no apparent link between them and the MSA. Nonetheless, the LSA at Shum Lake in Cameroon does have 14C dates in the range 32,700–12,800 BP. The most significant LSA site is Iwo Eleru, notable for the presence of modern human remains with “archaic” characteristics. A parallel situation has been detected at Ishango in the eastern Democratic Republic of Congo both indicating a hitherto unsuspected “deep substructure” in Late Pleistocene African populations.

AbstractThe paper reports on the sixth season of fieldwork of the Cyrenaican Prehistory Project (CPP) undertaken in September 2012. As in the spring 2012 season, work focussed on the Haua Fteah cave and on studies of materials excavated in previous seasons, with no fieldwork undertaken elsewhere in the Gebel Akhdar. An important discovery, in a sounding excavated below the base of McBurney's 1955 Deep Sounding (Trench S), is of a rockfall or roof collapse conceivably dating to the cold climatic regime of Marine Isotope Stage (MIS) 6 (globally dated to c. 190–130 ka) but more likely the result of a seismic event within MIS 5 (globally dated to c. 130–80 ka). The sediments and associated molluscan fauna in Trench S and in Trench D, a trench being cut down the side of the Deep Sounding, indicate that this part of the cave was at least seasonally waterlogged during the accumulation, probably during MIS 5, of the ~6.5 m of sediment cut through by the Deep Sounding. Evidence for human frequentation of the cave in this period is more or less visible depending on how close the trench area was to standing water as it fluctuated through time. Trench M, the trench being cut down the side of McBurney's Middle Trench, has now reached the depth of the latest Middle Stone Age or Middle Palaeolithic (Levalloiso-Mousterian) industries. The preliminary indications from its excavation are that the transition from the Levalloiso-Mousterian to the blade-based Upper Palaeolithic or Late Stone Age Dabban industry was complex and perhaps protracted, at a time when the climate was oscillating between warm-stage stable environmental conditions and colder and more arid environments. The estimated age of the sediments, c. 50–40 ka, places these oscillations within the earlier part of MIS 3 (globally dated to 60–24 ka), when global climates experienced rapid fluctuations as part of an overall trend to increasing aridity and cold.

The prehistory of Botswana concerns the sophisticated environmental knowledge, economic strategies, and social networks of the hunter-gatherer, pastoralists, and agropastoralist communities that have called Botswana home. Diverse subsistence strategies and societal structures ranging from heterarchical to hierarchical have coincided and responded flexibly to climate and environmental variables. Botswana has also played a central, but often overlooked, role in precolonial trade within the interior of Africa and across the Indian Ocean. Botswana contains well-preserved archaeological records for the Middle Stone Age, Late Stone Age, and Iron Age periods, including one of the highest concentrations of rock art in the world at Tsodilo Hills. The prehistory of Botswana extends over 100,000 years and includes successful, innovative, and adaptive occupations in a wide variety of environmental zones, from the Okavango Delta to the Kalahari sandveld, and better-watered hardveld areas in the east. Stone Age peoples adapted to both arid and wet lands, and the archaeological record includes early evidence for freshwater fish exploitation. Hunting with bone points dates to 35,000 years ago, with additional evidence for poisonous, reversible arrowheads between 21,000 and 30,000 years ago. Evidence for ritualized behavior through rock paintings, rock carvings, and the intentional destruction and abandonment of stone tools at Tsodilo Hills provides further insights to the social dimensions of early peoples. In the Iron Age, hunter-gatherer communities and agropastoralists participated in a regional and later protoglobal trade across the Indian Ocean for a thousand years before European involvement; as the regional economy intensified, large polities such as Bosutswe and even kingdoms such as the Butua state emerged, controlling access to resources such as game, ivory, salt, specularite, and gold. In the modern era, the historical archaeology of sites such as Old Palapye (Phalatswe) provide additional insight to historical documents that can contradict Eurocentric understandings of Botswana’s past.

AbstractThe middle reaches of the Nile River play a key role in the current models about the diffusion of modern Humans out of Africa, nevertheless the Early and the Middle Stone Age (Early Palaeolithic and Middle Palaeolithic) in central Sudan are poorly known. On-going investigation at al-Jamrab (White Nile region) highlights the archaeological potential of the central Sudan and illustrates the importance of an integrated approach combining archaeological excavation and palaeoenvironmental reconstruction for understanding cultural site formation and post-depositional dynamics. The stratigraphic sequence at al-Jamrab includes a thick cultural layer rich in Early and Middle Stone Age artefacts, preserved in a deeply weathered palaeosol developed on fluvial sediments. The cultural layer includes a two-fold human occupation covering the Middle Stone Age, with Acheulean and Sangoan bifacial artefacts, although an Early Stone Age/Middle Stone Age transitional phase cannot be excluded. The artefact-bearing unit is attributed to the Upper Pleistocene based on preliminary OSL dating, the local palaeoenvironmental context, and strong pedogenetic weathering. Considering the paucity of archaeological data for the Pleistocene of Sudan and the importance of this region in the study of human dispersal out of Africa, this preliminary work on a new site and its associated stratigraphic context provides insights into the early peopling of Sudan and adds one more tessera to the Eastern Africa picture.

Storage of symbolic information outside the human brain is accepted here as the first undisputed evidence for cultural modernity. In the hunter-gatherer context of the Stone Age this storage could include artwork, rapidly changing artefact styles and organized spatial layout of campsites. Modern human behaviour in this context is distinguished by a symbolic use of space and material culture to define social relationships, including significant groupings based on attributes such as kinship, gender, age or skill. Symbolism maintains, negotiates, legitimizes and transmits such relationships. It is argued here that artefacts are not inherently imbued with symbolism and that modern human culture cannot be automatically inferred from inventories of archaeologically recovered material culture. Evidence for the out-of-brain storage of symbolism in southern African sites first appears in the final phase of the Middle Stone Age at about 40,000 years ago.

AbstractThe paper reports on the third (2009) season of fieldwork of the Cyrenaican Prehistory Project, and on further results from the analysis of materials collected in the previous (2007 and 2008) fieldwork. Sediments in a 14 m-deep core drilled beside the McBurney trench provide an invaluable overview of the overall stratigraphic sequence, including at depths reached by the 1950s Deep Sounding but not yet investigated by the present project. Sampling of newly-exposed faces of the original excavation trench for dating (14C, ESR, OSL, U-series) and palaeoenvirommental indicators continued. Excavation was begun of sediments assigned to the early Holocene Libyco-Capsian (McBurney's Layer X), and of Pre-Aurignacian layers beside the top of the Deep Sounding. The Libyco-Capsian layers are particularly prolific in lithic debris, shells, and animal bones; preliminary analysis of the lithics suggests a development from Typical to Upper Capsian within the layers excavated in 2009. Geoarchaeological survey along the littoral to the west and east of the Haua Fteah identified complex sequences spanning most of the last interglacial-glacial cycle. Geoarchaeological survey south of the Haua Fteah characterized the major landforms of the Gebel Akhdar mountain and of the pre-desert and desert-edge zones further south, with Late Stone Age (Upper Palaeolithic and Epipalaeolithic) material being found especially on the southern side of the Gebel Akhdar, and Middle Stone Age (Middle Palaeolithic) material in the pre-desert and desert regions. The first suite of 14C dates (from charcoal samples taken in 2007) indicates the use of the Haua Fteah by Oranian hunter-gatherers during the Last Glacial Maximum and in the succeeding millennia, but not in the Younger Dryas cold/dry phase (c. 11,000–10,000 cal. BC), with Libyco-Capsian occupation resuming soon after the beginning of the Holocene c. 9000 cal. BC, suggesting that the cave, and perhaps the Gebel Akhdar in general, have a complex history as refugia for human settlement during the Pleistocene.

<p>Ga-Mohana Hill North Rockshelter (GHN) in the Northern Cape Province of South Africa is situated within the Summer Rainfall Zone, in the semi-arid (~300-400mm mean annual rainfall) southeastern edge of the Kalahari Basin. This location is significant as the dominant narrative for the evolution of modern humans has focused on Middle Stone Age archaeological sites along the southern cape coast of South Africa, with coastal resources and favourable climate conditions argued as key factors in driving the evolution of <em>Homo sapiens</em>. Semi-arid regions in the interior of South Africa, such as the southern Kalahari Basin, are often considered to have been too dry to sustain significant human occupation and activity, and have thus been overlooked. However, GHN does indeed preserve rich stratified Middle and Later Stone Age deposits, as well as abundant large relict tufa deposits that cover the surrounding hillside. These tufas, which are ambient temperature, freshwater calcium carbonate deposits, are indicative of past periods of flowing surface waters and shallow pools on the hillside. Laser ablation trace element mapping was used to pre-screen the tufa samples to target layers with high <sup>238</sup>U and little to no <sup>232</sup>Th concentration for U-Th dating. The resultant ages show that the tufa system at Ga-Mohana was active during five distinct intervals over the last 110 ka, three of which closely coincide with the timing of human occupation at the site, itself dated via OSL. The coincidence of tufa formation and human occupation suggests that the tufa-forming waters were a critical resource to human populations living in the area. This hitherto undiscovered source of fresh water, more than 600 km inland and as far back as 110 ka, stands to challenge the notion of an empty and arid interior.</p>

African Perspective

Southern Africa has a long and rich archaeological record, ranging from the Oldowan lithics in the Sterkfontein valley and Wonderwerk Cave (about 2 Ma) to Iron Age smelting (less than one thousand years ago) in Zimbabwe. A brief overview of charcoal analyses indicates applications in such areas as dating, vegetation and climate reconstructions, fuel use, medicinal use, and the interpretation of human behavior. Some of the research done in the 20th century mainly focused on charcoal for the purpose of dating, but this has diversified in the 21st century to include other applications. The focus is on South African sites, but research from Botswana, Lesotho, Swaziland, and Zimbabwe is included. Southern Africa has a very diverse woody component with more than fifteen hundred species from a flora of more than twenty-five thousand species so the establishment of regional modern reference collections of charcoalified woods has been instrumental in improving identifications of the archaeological taxa. Early Middle Stone Age charcoal records show that a diversity of woody species was burned. By Middle Stone Age times, records show the selection of woods for fuel, tinder, and medicinal use as well as cooking of starchy rhizomes. Late Stone Age and Iron Age records, in addition, show the use of woods for smelting and intense fires.
