AbstractOlieboomspoort is one of the few rock shelters in the vast interior of southern Africa documenting pulses of occupation from the Acheulean until the end of the Later Stone Age. Revil Mason excavated the site in 1954 and attributed the large Middle Stone Age (MSA) lithic assemblage to his middle phase of the so-called Pietersburg Industry. Recent work at the site has focused on the Holocene layers, but little is known about the earlier phases of shelter use. Here, we provide some background to the shelter, give a history of past research and present initial results following renewed fieldwork at the site. The MSA deposits contain abundant lithic artefacts and ochre, and we present an initial description of these cultural remains. Palynological analysis reveals limited potential for palaeoenvironmental reconstructions, but some faunal remains indicate open grasslands. We dated two equid teeth that provided highly consistent combined U-series-ESR estimates, resulting in a mean age of 150 ± 14 ka (1σ). Even when considering potential sources of uncertainty such as variations in water-intake, these fossils can securely be dated to Marine Isotopic Stage 6. Our reappraisal of site formation processes highlights the fact that the archaeological assemblage is strongly time-averaged. We discuss these different results in the context of a recently rekindled interest in the so-called Pietersburg Industry.

The continent of Africa has had a lengthy involvement in global maritime affairs and archaeological research with Middle Stone Age people using marine resources on the coasts of southern Africa, the Classical Pharos lighthouse of Alexandria, and Medieval Indian Ocean trade on the Swahili coast to the Atlantic triangular slave trade. Maritime archaeology is the identification and interpretation of physical traces left by people who use the seas and oceans. Middle Stone Age sites in South Africa such as Klasies River Mouth and Pinnacle Point have the earliest evidence for human use of marine resources including birds, marine mammals, and shellfish. This exploitation of marine resources was also coincident with the use of pigment, probably for symbolic behavior, as well as the production of bladelet stone tool technology. The extensive timespan of human activity on the coast around Africa occurred during changing relative sea levels due to Ice Ages and tectonic movement affecting the location of the coastline relative to maritime archaeological sites. Geomorphological changes may also take place over shorter periods such as the 1909 ce shipwreck of the Eduard Bohlen in Namibia lying c. one and half thousand feet landward of the shoreline. Ancestors of sea-going vessels have been recorded on rivers from dugout canoes excavated at Dufuna in northern Nigeria and the first plank-built boats, such as the Old Kingdom Royal Ship of Cheops of Khufu, found at the Giza pyramids, which imitated the shape of earlier papyrus rafts. Classical documents such as the Periplus Maris Erythraei and Ptolemy’s Geographia record Arabian and Indian trade with eastern Africa including ivory and rhinoceros horn and describe fishing practices using baskets and sewn-hull boats of the inhabitants. The increase in oceanic trade links here during the medieval period encouraged the formation of Swahili port cities such as Kilwa and Mombasa. The former was in a strategic position to manage much of the gold trade between Sofala in Mozambique and the northern Swahili Coast. Portuguese forts, constructed in the 15th and 16th centuries on their trade routes around Africa, such as Elmina Castle in Ghana, Fort Jesus in Mombasa, Kenya, and Fort São Sebastião on Mozambique Island, dominate the ports and harbors. The first sub-Saharan underwater scientific investigations took place in 1976 of the Portuguese frigate Santo Antonio de Tanna that sunk during an Omani siege from 1696 to 1698. At Elmina in West Africa, studies were made of wreck-site formation processes around the 17th-century Dutch West India Company vessel Groeningen, which had caught fire when firing its guns in salute to Elmina Castle after arrival. More broad-based studies that interpret the functioning of the African maritime society in its wider environmental setting, both physically in the context of its religious buildings, harbors, fishing grounds, sailing routes, and shipwrecks, and by taking account of non-material aspects of the beliefs that influence behavior of coastal societies, have led to interpretations of their maritime outlook.

AbstractUmhlatuzana rockshelter has an occupation sequence spanning the last 70,000 years. It is one of the few sites with deposits covering the Middle to Later Stone Age transition (~40,000–30,000 years BP) in southern Africa. Comprehending the site’s depositional history and occupation sequence is thus important for the broader understanding of the development of Homo sapiens’ behavior. The rockshelter was first excavated in the 1980s by Jonathan Kaplan. He suggested that the integrity of the late Middle Stone Age and Later Stone Age sediments was compromised by large-scale sediment movement. In 2018, we initiated a high-resolution geoarchaeological study of the site to clarify the site formation processes. Here, we present the results of the excavation and propose a revised stratigraphic division of the Pleistocene sequence based on field observations, sedimentological (particle size) analyses, and cluster analysis. The taphonomy of the site is assessed through phytolith and geochemical (pH, loss on ignition, stable carbon isotope) analyses. The results indicate a consistent sedimentological environment characterized by in situ weathering. The analysis of the piece-plotted finds demonstrates semihorizontal layering of archaeologically dense zones and more sterile ones. There was no indication of large-scale postdepositional sediment movement. We show that the low-density archaeological horizons in the upper part of the Pleistocene sequence are best explained by the changing patterns of sedimentation rate.

Abstract. The Middle Pleistocene site Kärlich-Seeufer is the youngest archaeological site in the Kärlich clay pit which, since the beginning of this century, has been the most important exposure for Quaternary stratigraphy in the Central Rhineland. The site was discovered in 1980 and excavated during the following years. Together with an Acheulean lithic assemblage and faunal remains, numerous macroscopic plant remains were recovered in an outstanding state of preservation. Wood of Abies and Quercus dominates the botanical assemblage in the form of trunks and branches. The faunal assemblage comprises: Panthera leo ssp., Elephas antiquus, Equus sp., Sus scrofa, Cervus elaphus, Rangifer sp. as well as Bos vel Bison. Elephas antiquus dominates the faunal assemblage and the molars of this species show a certain robustness in comparison to teeth of other Middle- and Upper Pleistocene Elephas antiquus populations. The results of the palynological analysis show that the sediments containing the archaeological assemblage were deposited during the second half of an interglacial phase, the Kärlich Interglacial. Moreover, these results allow detailed reconstruction of palaeoecological conditions during the Middle Pleistocene. Analysis of site formation processes, taking into account the sedimentology of the archaeological layers, the lithic and faunal assemblages and the numerous macroscopic palaeobotanical remains, shows that the Seeufer site functioned as a sediment trap in which evidence for hominid activity has been re-bedded together with wood and faunal remains. At Kärlich-Seeufer, as at other European Lower Palaeolithic sites, claims for hominid activity are very difficult to assess and can only be demonstrated for the lithic assemblage. The contribution of hominids to the presence of other categories of finds remains obscure.

The dating of the Stone Age sequence in southern Africa has been considerably revised over the last decade, and one of the anomalies which has resulted is that the Middle Stone Age, now dated to beyond 30,000 B.P., does not immediately precede the Later Stone Agesensu stricto. The excavation and analysis of occupation horizons dating between the most recent Middle Stone Age assemblages and the Holocene is therefore of particular interest. Nelson Bay Cave, situated on the southern coast of South Africa, contains deposits which partly fill the “gap” between the Middle and Later Stone Ages, and the occupation horizons dating between about 18,000 and 5000 years ago are described in this paper. Changes in the habitat in the vicinity of the site caused by sea-level and vegetation changes coincident with the amelioration of temperatures at the end of the Pleistocene are clearly marked in the faunal remains at the site. Largely correlated with the faunal changes (which includes the introduction of marine resources to the cave at about 12,000 B.P.) are changes in the stone artifact assemblages. Three industries are recognized in the sequence: the Robberg, characterized by microbladelets produced from bladelet cores and a few small scrapers and backed tools; the Albany, characterized by large scrapers and an absence of backed tools; and the Wilton, characterized by a variety of Formal Tools including relatively large numbers of small scrapers and backed tools. These changes in artifact-manufacturing traditions are interpreted as signaling adjustments to changing environmental conditions. An explanation for these adjustments is not sought in a simple cause-and-effect relationship between the environment and the cultural response; artifact changes are seen instead as the result of a twofold process, with the environment acting as an external stimulus to change, and the direction of the artifact change governed by the selection of a range of possibilities offered by the technology of the Later Stone Agesensu latothat was widespread in subequatorial Africa during the last 20,000 years.

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.

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.
