Ochre is a ubiquitous artefact in Middle Stone Age (MSA) contexts throughout Africa and the Near East. Archaeological evidence for the abrasive processing of ochre to extract pigment powder becomes increasingly prevalent after 100 ka. The habitual exploitation of ochre is interpreted as evidence for symbolism, a proxy for the origin of language and as a key element of ‘symbolic’ and ‘modern’ human behaviour. Evolutionary explanations agree that ochre and the products of its processing played a significant role in the adaptive strategies of early modern humans, but they differ in the functions assigned to it. I therefore ask the following question: What role did symbolic and functional applications of ochre play in the enhancement of prehistoric technology, and how may these have functioned to promote and maintain social relations within MSA Homo sapiens societies? With the aim of answering this question, I follow a chaîne opératoire approach to elucidate the exploitation of ochre during the MSA. First, I present the results of an experimental study devised to infer the methods employed to process ochre. It is demonstrated that functional data derived from actualistic experiments can enhance our understanding prehistoric behaviour. Second, I describe one of the oldest instances of a deliberate engraving on ochre at 100 ka to 85 ka. I consider the possibility that specific types of raw material were selected for engraving purposes and expand on whether all engraved depictions inevitably functioned in ‘symbolic’ contexts. The third objective entails the evaluation of an often cited functional hypothesis for ochre, namely the use of red ochre as a ‘hide-tanning’ ingredient. I also introduce and discuss three further functional hypotheses, namely those concerning the use of ochre as a form of mineral supplementation and detoxification agent, as a sunprotection element and as an insect repellent. Ethnoarchaeological research has proven to be informative in terms of revealing a range of functional uses for red ochre. I therefore consider how data derived from the Ovashimba of northern Namibia can enhance current understandings of ochre use in the MSA. I propose that in order to assess any hypothesis concerning the exploitation of ochre in the MSA methodically and in a scientific manner, it is necessary to engage with the theories and analytical methods of cognitive and technical sciences not normally viewed as applicable to archaeological enquiry.

The rock engraving site of Driekopseiland, west of Kimberley in the Northern Cape is distinctively situated on glaciated basement rock in the bed of the Riet River, and has a wealth of over 3500 engravings, preponderantly geometric images. Most other sites in the region have greater proportions of, or are dominated by, animal imagery. In early interpretations, it was often considered that ethnicity was the principal factor in this variabilty. From the 1960s the focus shifted more to establishing a quantative definition of the site, and an emperical understanding of it within the emerging cultural and environmental history of the region.

Thesis (D Phil)--Stellenbosch University, 2000. / ENGLISH ABSTRACT: The Late Pleistocene, Middle Stone Age artefact sequence at the Klasies River main site, was studied to establish what information this held for inferences on the emergence of symbolic thought and communication. The approach adopted was to complement traditional typological analysis by a technological study of artefact production within the framework of the chafne opératoire. The results show that technology was aimed at producing preformed blanks. In the choice of materials, the technique and method of blank production and the retouch of blanks, arbitrary or stylistic choices were made. Changes in stylistic conventions can be documented through the sequence. Changing conventions in artefact production show that the lives of the people who made the artefacts were structured in a symbolic web. These results together with evidence from evolutionary biology, show that by at least 115 000 years ago, people were able to think and speak symbolically. This African archaeological evidence for the emergence of symbolism, a defining attribute of modem peoples, is much older than previously considered. KEYWORDS: Klasies River, Middle Stone Age, technology, symbolic communication, human evolution. / AFRIKAANSE OPSOMMING: Die Latere Pleistoseen, Middel Steentydperk artefakte by Klasiesrivier vindplaas is bestudeer om te bepaal watter kennis ingewin kan word aangaande die ontstaan van simboliese denkwyse en kommunikasie. Die benadering wat gevolg is, was om tradisionele tipologiese analise te komplementeer met 'n tegnologiese studie van artefak produksie binne die raamwerk van die chafne opératoire. Die resultate demonstreer dat tegnologie gemik was op die produksie van voorafgevormde skilfers. Die keuse van roumateriaal, die tegniek en metode van produksie en die herafwerk van skilfers is gelei deur arbitrêre stilistiese keuses. Veranderinge in hierdie konvensies kan gedokumenteer word deur die hele sekwens. Hierdie verandering is tipies van mense wie se lewens gestruktureer word deur 'n simboliese web. Dié resultate, en dié van evolusionêre biologie, dui daarop dat mense reeds teen 115 000 jaar gelede simboliese denke en spraak magtig was. Hierdie bewyse vanuit Afrika vir die ontstaan van simboliese gedrag is veel vroeër as vantevore gereken. SLEUTEL WOORDE: Klasiesrivier, Middel Steentydperk, tegnologie, simboliese kommunikasie, menslike evolusie.

A thesis submitted to the Faculty of Science, University of the Witwatersrand, Johannesburg, in fulfilment of the requirements for the degree of Doctor of Philosophy. Johannesburg, 2014. / The site of Canteen Kopje in Barkly West, South Africa, has provided the archaeological record with an invaluable collection of Earlier Stone Age artefacts. An alluvial deposit approximately 1km from the modern Vaal River, the site contains an abundance of artefacts. A 2007 – 2009 excavation in Pit 6 has provided an assemblage of over 15,000 artefacts that has been dated by cosmogenic nuclide burial method. Three distinct assemblages show technological changes through time of the earlier Acheulean industrial complex. The youngest industry, the Prepared Core Technology Assemblage, is dated to 1.2 ± .07 Ma and contains Victoria West prepared core technology. Beneath it is the Organised Core Assemblage which is void of Victoria West prepared core technology but contains cores that demonstrate more organised knapping techniques in the form of asymmetrical control. This assemblage is dated to 1.51 ±0.8 Ma. Finally, the underlying Basal Early Acheulean Assembage lacks both prepared cores and organised cores and is >1.51 Ma in age. The abundance of large angular clasts of andesite in the area made multiple knapping strategies effective for the manufacture of large flakes. A technological sequence in the knapping strategies has emerged in this excavation, from simple cores to organised cores and finally prepared cores. The older technologies clearly display the roots of prepared core technology in the asymmetrical control of the organised knapping methods. The overall success of the knapping strategies prior to the appearance of the Victoria West industry in the Canteen Kopje archaeological record creates questions as to why more complex strategies might have been implemented over time. Analysis of the assemblages from the Pit 6 excavation fails to provide a clear technological explanation within the empirical data as to why this change occurs. This research therefore argues that the Victoria West prepared core knapping strategy is a localized stone age culturally motivated knapping tradition.

The arid interior of South Africa lacks long, continuous and well-dated climate and environmental proxy records that can be compared with cultural sequences and with broader global climate records. This thesis develops the first substantial terrestrial environmental sequence for the interior of southern Africa at the site of Wonderwerk Cave, spanning two million years of prehistory. Changes in vegetation and humidity over time were investigated by means of carbon and oxygen stable isotope analysis on fossil herbivore enamel and ostrich eggshell, creating two independent proxy datasets. The Holocene record was used as a baseline for comparing the Pleistocene sequence, but required chronological tightening. Therefore, nine new radiocarbon dates were obtained, and calibrated and modelled with existing dates to provide a firmer chronology. The ostrich eggshell isotope record suggests arid but variable conditions, with distinct phases of increased humidity in the Early Pleistocene and mid-Holocene. Enamel stable isotope results show clear differences in local resource availability between the Early and Mid-Pleistocene, and then between the Pleistocene and Holocene, with an overall trend of increasing aridity. In particular, the onset of dietary specialisation in grazers at 0.8Ma is linked to expanding C4 grasslands. Aridity was not the driver behind the increase in C4 grasses, but changing pCO2 levels at the Mid Pleistocene transition were identified as a possible key factor. The presence of C3 and C4 grasses in the Early Pleistocene, when compared to the domination of C4 grasses today, was fostered by reduced rainfall seasonality. Regional independent developments have to be considered, as other regions in South and East Africa show C4 dominated diets in herbivores at earlier times than at Wonderwerk Cave. In the Holocene, higher temporal resolution indicates phases of environmental change coinciding with changes in the cultural record.

Thesis (MA (Geography and Environmental Studies))--University of Stellenbosch, 2005. / The West Coast Fossil Park near Langebaanweg in the Western Cape, South Africa, is known for its abundance of marine, freshwater and terrestrial fossils of Mio-Pliocene age. The fossil bearing deposits reflect the complex and varied depositional environments, which were influenced by the change in course of the Berg River and regressions and transgressions of sealevel. The fossil deposits at this site are world-renowned for their species richness and uniqueness and there was a need to gain an in-depth understanding of the events that gave rise to this situation. To understand these complexities, it was necessary to construct a composite model of the pre-history of the West Coast Fossil Park, incorporating topological, geological and palaeontological data. GIS provided the ideal platform to integrate data from such varied sources, using spatial correlation to interpret commonalities. Subsequently, a spatially explicit database of the present-day study area, from Dwarskersbos in the north to just north of Yzerfontein in the south, was constructed. The oldest geological formation, the basement layer, as well as three successive formations was reconstructed on a regional scale using borehole data. Interpolation of point data to regional surfaces was a dual process incorporating expert opinion and purpose-built tools within ESRI’s ArcInfo and ArcMap 8.3. A similar reconstruction at a finer scale was done for the West Coast Fossil Park area using kriging as an interpolation method. These reconstructed geological layers can be used to predict the depth and location of fossil-bearing deposits. There is scope for further study and analysis to compare the accuracy of alternative interpolation methods, and combining it with field-based validation of modelled outputs.
