Blombos Cave is well known as an important site for understanding the evolution of symbolically mediated behaviours among Homo sapiens during the Middle Stone Age, and during the Still Bay in ...particular. The lower part of the archaeological sequence (M3 phase) contains 12 layers dating to MIS 5 with ages ranging from 105 to 90 ka ago (MIS 5c to 5b) that provide new perspectives on the technological behaviour of these early humans. The new data obtained from our extensive technological analysis of the lithic material enriches our currently limited knowledge of this time period in the Cape region. By comparing our results with previously described lithic assemblages from sites south of the Orange River, we draw new insights on the extent of the techno-cultural ties between these sites and the M3 phase at Blombos Cave and highlight the importance of this phase within the Middle Stone Age cultural stratigraphy.

Howiesons Poort (HP) sites, over the past decades, have provided exceptional access to anthropogenic remains that are enhancing our understanding of early modern human behaviour during the Middle ...Stone Age in southern Africa. Here, we analyse the technological and typological trends in the lithic record that form part of these behaviours, based on the HP sequence recently excavated at Klipdrift Shelter, located on the southern Cape coast of South Africa. This study contributes to enhance knowledge on the mechanisms of changes that occurred during the transition to the post-HP. Despite patterns of continuity observed, notably for core reduction methods, the seven successive lithic assemblages show significant changes in the typological characteristics and raw material selection but also in the relative importance of blade production over time. However, these changes are not necessarily synchronic and occur either as gradual processes or as abrupt technological shifts. Consequently, we cross-examine the association between the lithic phasing and other anthropogenic remains within the HP sequence at Klipdrift Shelter. We explore the implications of these patterns of changes in terms of cultural behaviours and population dynamics during the HP and we highlight the relationship between the different phases of the HP sequence at Klipdrift Shelter and those from other South African HP sites.

The range of technological elements that marks the Middle Stone Age originated more than 300,000 years ago and formed the basic tool kit for an extended period of time. No spatial and chronological ...patterns can be identified from the Early Middle Stone Age until marine isotope stage (MIS) 5, and there is no cumulative trend of increasing complexity and diversity; instead, periods of complexity come and go. The Howiesons Poort and Still Bay techno-complexes, broadly associated with MIS 4, are recognized across various ecological zones of South Africa. These techno-complexes contain relatively more retouched tools and exhibit heightened levels of what is described as innovative practices. The Howiesons Poort is the best understood industry in the Middle Stone Age of South Africa. Its unifying technological characteristic is the almost exclusive use of a blade and bladelet production system, but subtle changes in types of backed artefacts, other retouched tools, and raw material exploitation patterns occur through time. Technological preferences change in the ensuing MIS 3 period, and other strategies and implement types become popular, particularly unifacial points, but trends once again are less clear. This historical review of the technological diversity in the Middle Stone Age of South Africa emphasizes that the roots of some innovations may lie in the earlier Middle Stone Age and that innovation is best understood within the context of local historical trajectories of technological change in South Africa.
The recent publication of previously unrecognised musical instruments from two South African Later Stone Age deposits has prompted us to relook at some of the bone tools from Klasies River Main site ...(KRM). Notched bones are enigmatic artefacts found throughout the world and attributed diverse functions, including sound-producing instruments. We re-analyse the three pieces of notched bone from Klasies River Main site for use-traces that may indicate their use as musical rasps. Although we find no evidence to support their use as rasps, the use-wear and ancient starch residues suggest a complicated use history in which several activities may be implicated. While Francesco d’Errico’s original interpretation of their use as skin abraders still stands as plausible, we conclude that the presence of quantities of ancient starch grains, coupled with the absence of ancient animal residues, implicates their use in some kind of plant processing activity, either exclusively or in addition to other uses.
The archaeological record, particularly of shellfish, from the Klasies River main site (KRM) is important in understanding the fluctuating nature of coastal occupational patterns and changing coastal ...ecologies. In this paper, we provide new uranium–thorium (U-Th) dates for one of the earlier phases of coastal exploitation at KRM, and the microstratigraphic analyses generate novel information about the taphonomy of shell-bearing deposits from the Later Stone Age (LSA) to the MSA I period that, in turn, provide a broader context for middening at the site. A wide range of syndepositional taphonomic processes related to human activities and post-depositional effects include burning, fragmentation and compaction, chemical alteration, and cementation. Despite such issues influencing recovery, shellfish data are informative and are presented from three layers of the Witness Baulk: Shell Midden One (SMONE), Black Occupational Soils (BOS), and Silty Black Soils (SBLS). These coarse shell midden deposits exhibit visible decalcification coupled with cementation with secondary carbonate formation in association with conditions of high moisture and soft sedimentation deformation of the underlying sediments of SBLS. This stratigraphy section is chronologically anchored for the first time using U-Th dating of speleothems associated with a hiatus after the deposition of BOS. The three ages, 110,060 ± 1,100, 109,800 ± 970, and 106,000 ± 2,100 years, place the BOS layer as the base of the SASL sub-member at over 110 ka, making the underlying middens from the LBS member even older. The zooarchaeological analyses of the three layers indicate coastal ecological changes from more sheltered conditions prior to the hiatus, with the exploitation of alikreukel and brown mussels predominating. Before 110 ka, in BOS and SBLS, more exposed coastal conditions occurred, and the diversity of exploited shellfish increased. SMONE and BOS are associated with MSA II/Mossel Bay lower lithic technology and SBLS with MSA I technology, indicating asynchronous coastal ecological and technological changes. The MIS 5c-d evidence for early coastal occupation at KRM provides details on the period during which coastal occupation became stable and systematic on the South African coast and puts the KRM amongst the handful of sites with shell-bearing deposits, occurring prior to 110 ka in South Africa.
South Africa and Lesotho (SAL) have been inhabited by tool-producing hominins for at least two million years. Most of the information we have about the activities and technological skills of Stone ...Age people is thanks to the durability of stone tools that not only provide evidence for the presence of humans, but more importantly, encode human technological achievements during more than 99% of the history of our genus. The characteristics of this long and probably continuous history of human occupation of an extensive landmass have been influenced to some extent by changes in demography, socioeconomic factors and environmental variations affected by geology, geomorphology, climate, fauna and flora. The result is an extraordinarily rich and complex record of social and technological changes throughout the Stone Age. Archaeological research over the past century or more has uncovered an ever-increasing variety of data, yet researchers continue to face the challenge of meaningfully describing the variability in stone tool manufacture through time and across space, and investigating the nature of, and reasons for, change. Classification schemes have been concerned with both form and function of stone tools, and have recently begun to pay more attention to the techniques of manufacture as well. The purpose of this short discussion paper and its Appendix is to examine the criteria for classification of stages in the Stone Age sequence, to draw together new information on dated assemblages to improve our knowledge of the technological sequence, and to propose a few adjustments to the nomenclature.
Marine Isotope Stages (MIS) 4 and 3 were significant periods encompassing some 50,000 years, including at least two techno-cultural entities: the Howiesons Poort (HP) and post-HP. Exploring ...subsistence and environmental changes during these periods may help us understand broader aspects of behavioural and occupational patterns over MIS 4 and 3. In this paper, we report on taphonomic analyses of a sample of early HP, late HP and post-HP fauna from Klasies River main site cave 1A. We use these and other faunal data to examine the links between subsistence behaviour and the environment during the HP and post-HP. The results of our analyses indicate that percussion marks are abundant in the HP, with percussion mark frequencies more prevalent in the later HP than the early HP indicating that humans were the primary accumulators of fauna in the HP. Other taphonomic data such as fracture patterns, burning and trampling marks also suggests that human activity was more prevalent in the HP than the post-HP. In contrast, in the post-HP, the prevalence of zoogenic marks on small mammal remains, and comparisons to actualistic assemblages indicate that carnivores probably contributed significantly to the post-HP assemblage. In all the samples investigated, crania dominate skeletal-part profiles. This could be a result of taphonomic bias, or it could indicate that foraging likely occurred relatively close to the site. Analyses of carcass-part utility show that marrow-extraction may have been a key subsistence strategy in the HP. In the post-HP, bone density-mediated attrition had a significant effect on fauna making it challenging to ascertain subsistence patterns, but preliminary analysis may also suggest marrow extraction in combination with other strategies.
Post-depositional taphonomic marks such as manganese staining suggest that post-HP and late HP deposits were significantly more affected by moisture than the early HP deposits. Previous investigations of large mammal data point to more closed environments in the early HP, while our data indicate that the environment in the late HP and post-HP was largely similar. In comparing our data to previously analysed micromammal proxy data, we show that major environmental changes at KRM occurred after the shift to post-HP lithic technology. However, the taphonomic data suggests a close relationship between changing subsistence strategies and the MIS4/3 transition.
