The Oldowan and Early Acheulean Mammalian Fauna of Wonderwerk Cave (Northern Cape Province,South Africa)

We describe and discuss the large vertebrates recovered from the basal layers (Strata 12 and 11) of Excavation 1 at Wonderwerk Cave, a site located in the Kuruman Hills, Northern Cape Province, South Africa. Stratum 12 is associated with a small core and flake Oldowan assemblage while Stratum 11 contains some Acheulean material. Based on palaeo-magnetism, the time span covered by these Strata is estimated to date to ca.1.8–1.1 million years ago. Taxa identified include late Makapanian forms, such as Procavia transvaalensis, Procavia antiqua, a hipparionine and an unnamed species of large caprine, also found in the Makapan Limeworks deposits, confirming the antiquity of these layers. The bones are highly fragmented due to the action of multiple agencies, both pre- and postdepositional, which prevented diagnosis in many cases to lower levels of taxonomy. In support of other palaeo-environmental proxies from Strata 12 and 11, the large mammal remains reflect a semi-arid ecotone palaeo-environment, consisting of a mix of taxa associated with broken, montane habitat and semi-arid grassland-savanna plains habitat.     

An Early Pleistocene Phytolith Record from Wonderwerk Cave,Northern Cape,South Africa

Grass silica short cell phytoliths were sampled from the four lowermost archaeological strata in excavation 1 at Wonderwerk Cave and offer an independent record of climatic change during an episode of Early Stone Age hominin occupation at the cave. Linked to differences in growing season temperature and the geographic distribution of C₃ and C₄ grasses in southern Africa, fossil grass phytoliths were used to trace palaeoenvironmental shifts at the site. The results suggest that Early Pleistocene environmental conditions at the cave fluctuated: between wetter and drier summer–rainfall growing conditions (C₄) towards the end of the Olduvai subchron and the beginning of the subsequent interval of reversed polarity, to mostly dry and cooler winter–rainfall growing conditions (C₃), that continued throughout the interval. It ended with a shift towards increased summer rainfall aridity at around one million years ago. The fluctuation between markedly wetter and drier C₄ conditions at the cave (NADP-me grass types vs. NAD-me grass types) does not support the premise that the expansion of C₄ grasslands was always coupled with increased aridity.     

Revisiting the Parietal Art of Wonderwerk Cave,South Africa

Seen by all who visit Wonderwerk Cave, the rock paintings that adorn its walls have attracted less attention than many other aspects of the site. The paper gives a brief account of their history and significance and of factors that have constrained their study. Graffiti damage and restoration added layers through which researchers would need to delve in order to understand them archaeologically. Pointing to directions for future work, the paper concludes with discussion on a currently debated category of southern African rock art, the “non-entoptic” geometric rock art tradition, to which the Wonderwerk Cave rock paintings would belong. A shift in theoretical focus is advocated for comprehending local contingencies in the formation of rock art “traditions” rather than simply assuming the prior existence of such constructs.     

New Excavations at Border Cave,KwaZulu-Natal,South Africa

New excavations at Border Cave use high-resolution techniques, including FT-IR, for sediment samples and thin sections of micromorphology blocks from stratigraphy. These show that sediments have different moisture regimes, both spatially and chronologically. The site preserves desiccated grass bedding in multiple layers and they, along with seeds, rhizomes, and charcoal, provide a profile of palaeo-vegetation through time. A bushveld vegetation community is implied before 100,000 years ago. The density of lithics varies considerably through time, with high frequencies occurring before 100,000 years ago where a putative MSA 1/Pietersburg Industry was recovered. The highest percentage frequencies of blades and blade fragments were found here. In Members 1 BS and 1 WA, called Early Later Stone Age by Beaumont, we recovered large flakes from multifacial cores. Local rhyolite was the most common rock used for making stone tools, but siliceous minerals were popular in the upper members.     

Later Stone Age shellfishing behaviour at Dunefield Midden (Western Cape,South Africa)

Later Stone Age shellfishing behaviour was analysed within a unique archaeological context using computer aided spatial analysis techniques. The young age, the short occupation and large excavated area of the site ‘Dunefield Midden’ (Western Cape, South Africa) made it an ideal candidate for the investigation of patterns within shellfish distributions. A model describing the factors involved in causing shellfish patterning on archaeological sites was developed and used as a guide for the interpretation of the analyses. Human behaviour was successfully identified to have produced patterns in the shellfish distributions providing a new understanding of the practices of the prehistoric inhabitants. All results were summarized in a model of shellfishing behaviour at ‘Dunefield Midden’.     

The use of OSL dating in unstructured sands: the archaeology and chronology of the Hutton Sands at Canteen Kopje (Northern Cape Province, South Africa)

Archaeological research at the site of Canteen Kopje, Northern Cape Province, South Africa, has focused on the rich Earlier Stone Age assemblages recovered from the Younger Vaal Gravels. This paper presents the results of excavation and optically stimulated luminescence (OSL) dating of the overlying Hutton Sands. We discuss the evidence for colonial period interaction between diamond miners and indigenous groups at the site, as well as the presence of an earlier phase of terminal Middle Stone Age/early Later Stone Age occupation. The OSL analyses demonstrate the potential distortion of OSL ages due to substantial bioturbation and its effect on the dating of archaeological sites situated in unconsolidated sands.     

Laser scanning for conservation and research of African cultural heritage sites: the case study of Wonderwerk Cave,South Africa

The ‘African Cultural Heritage and Landscape Database’ project, initiated and directed by the senior author and administered by Aluka (www.aluka.org), is aimed at the creation of a digital library of spatial and non-spatial materials relating to cultural heritage sites in Africa. The archaeological site of Wonderwerk Cave (South Africa) is one of the 19 sites documented to date using laser scanning, conventional survey, digital photogrammetry and 3D modelling. To date, it is one of the few archaeological caves worldwide to be fully scanned. This paper explores the different uses to which the spatial data derived from this cave have been, or will be, put – for historical and educational purposes, scientific research and site conservation and development.     

The Technology of the Early Oakhurst Lithic Techno-Complex from Klipdrift Cave,Southern Cape,South Africa

The analysis of the lithics recovered from the layers dating between cal bp 10,700 and cal bp 13,700 at Klipdrift Cave, southern Cape, South Africa, provides new information on the Oakhurst techno-complex. A comparison with contemporary sites such as Matjes River Rock Shelter indicates not only technological similarities, but also unexpected differences. The Klipdrift Cave Oakhurst shares many characteristics typical of this techno-complex from the southern Cape, for example, in the dominance of quartzite, irregular and unstandardised flakes; the occurrence of irregular cores; and typical large side and end scrapers. It differs from most coastal Oakhurst sites however, in the more intensive exploitation of quartz, and the presence of a blade component, especially in the lowermost layers. Palaeoenvironmental data, derived from stable isotope analysis of ostrich eggshell, suggest that it was dry in this region during this time period. This was partially a result of the colder conditions that prevailed during the Younger Dryas. The lithic technological production techniques are stable at Klipdrift Cave during the period that the site was occupied from cal bp 13,700 to cal bp 10,700. Our data suggest that the lithic technology did not change in response to possible climatic variability.     

Rock Hyraxes (Procavia capensis) from Middle Stone Age Levels at Blombos Cave,South Africa

The ～100 ka Middle Stone Age levels at Blombos Cave, southern Cape, South Africa, contain numerous rock hyrax (Procavia capensis) remains. It is often ambiguous to interpret rock hyrax remains from archaeological deposits deriving from cave and shelter sites in southern Africa as the agent or agents of accumulation may be difficult to establish. In this paper, the different taphonomic signatures separating anthropogenic from natural accumulations at Blombos Cave are considered. The analysis indicates that although a few specimens show evidence for raptor and carnivore accumulation, there is also substantial evidence that suggests humans preyed on these small mammals during different times of the year.     

Geoarchaeological investigations at Diepkloof Rock Shelter,Western Cape,South Africa

The sedimentary sequence at Diepkloof Rock Shelter formed through a complex interaction of depositional and post-depositional processes and was variously influenced by biogenic, geogenic, and anthropogenic agents. Here, we present the results of a micromorphological study of the sediments at Diepkloof, focusing in particular on the numerous anthropogenic inputs and modifications recorded within the sequence. By applying the microfacies concept, we were able to identify hearth burning and maintenance, bedding construction and burning, and surface modification by trampling as major processes that contributed to the formation of the site. The human activities recorded within the sediments show a marked change throughout the sequence, implying a shift in the use of the site over time. The present study also provides a context for evaluating other classes of artifacts and data collected from the site.     

Later Stone Age ostrich eggshell bead manufacture in the Northern Cape,South Africa

Two different prehistoric manufacturing pathways are identified in the manufacture of ostrich eggshell beads in the South African Later Stone Age. In Pathway 1, blanks are drilled prior to being trimmed to rough discs. This is the dominant production strategy and is consistent with most ethnographic accounts. That in which the trimming occurs first, Pathway 2, was rarely practiced. The data from five bead factory sites in Namaqualand show that most breakage occurs during the drilling stage and that the production process has not changed through the last 4000 years. The use of grooved stones for smoothing beads is contentious and the identity of drilling tools remains unknown. Contrary to the suggestions of others, beads seem to have been readily produced at both short and long term occupation camps and scarcity of ostrich egg is unlikely to have been a determining factor. The lack of production debris reflecting large beads suggests these beads were brought into Namaqualand from elsewhere.
