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.     

The Taphonomy of the Final Middle Stone Age Fauna from Sibudu Cave,South Africa

This study applies a taphonomic analysis to the final Middle Stone Age faunal assemblage from Sibudu Cave, South Africa, by assessing bone surface modifications, breakage patterns and skeletal element abundances. Cut marks, percussion marks, severe fragmentation and the high frequency of burned bone combine to demonstrate that human behaviour was the principal agent in the assemblage's formation. These results are consistent with previous research on earlier occupations of Sibudu during the Middle Stone Age. Moreover, this assemblage is proposed to reflect regular site maintenance and cleaning. This conclusion is consistent with previous research that demonstrates systematic site maintenance during the Middle Stone Age at Sibudu and emphasises this behaviour as being a consistent activity for Middle Stone Age foragers.

Behavioural and Taphonomic Patterning at Katanda 9: a Middle Stone Age Site, Kivu Province, Zaire

Katanda 9, an open air Middle Stone Age site, contains a dense vertically compressed accumulation of lithic and faunal remains. The physical state of these materials indicates prolonged surface exposure before burial and the site shares essential characteristics therefore with many Lower and Middle Stone Age and Lower and Middle Palaeolithic occurrences in Africa and Eurasia. An important goal of archaeological research is to determine what, if any, anthropogenic signature can be extracted from distributional data and this article utilizes Katanda 9 to suggest an approach to such spatial analysis. It employs a bottom-up, top-down strategy which works in sequential fashion first to determine and control for taphonomic bias and secondly to fit the resultant pattern to models of hominid behaviour. It proposes that questions be posed in nested hierarchical fashion and that probabilities of correctness be assessed. It concludes that the distribution of materials observed at Katanda is most consistent with a nuclear family pattern.     

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.     

Thermoluminescence dating of a Stillbay–Howiesons Poort sequence at Diepkloof Rock Shelter (Western Cape,South Africa)

New excavations have been undertaken at Diepkloof Rock Shelter (DRS; South Africa) since 1999. It is one of the very few sites where Howiesons Poort and Stillbay assemblages can be collected from the same archaeological sequence. These Middle Stone Age techno-complexes are particularly interesting for their affinities with the much younger Later Stone Age facies, and their association with evidence for symbolic behaviour. Establishing their chronology is therefore particularly important for the understanding of the apparition and the evolution of the so-called “modern” behaviours. Data already available suggest ages ranging from 55 to 80 ka for the Howiesons Poort and from 70 to 80 ka for the Stillbay techno-complexes in several South African sites. The thermoluminescence dating undertaken at DRS on 22 stone samples originating from the entire stratigraphic record indicates intervals starting 10–50 ka earlier for these techno-complexes in this site. Possible caveats in the dating process are examined but to the best of our current knowledge must be rejected.     

Changing patterns of carnivore modification in a landscape bone assemblage, Amboseli Park, Kenya

This study compares the landscape-scale taphonomic signal of carnivore modification to the surficial bone assemblage in Amboseli Park, Kenya as it was in 1975 and 2002–2004. Change in predator abundances over time provides a means of assessing the taphonomic signal of carnivore-mediated bone consumption and destruction under differing ecological conditions and varying levels of conspecific competition for resources. The landscape assemblage indicates taxonomic variation in the patterning of carnivore modification to ungulates of different size classes as well as within equivalent size classes. Analyses of long bone elements indicate that the differential destruction of limb ends and the strength of the correlation between limb end abundance and bone mineral density provide an indication of the intensity of carnivore modification to a faunal assemblage. The ability to infer levels of carnivore modification based on limb elements can provide faunal analysts with the tools to determine whether the taphonomic signals in the fossil record relate to carnivore modification, hominin transport of appendicular elements, or both.     

Lithic Microwear Analysis of Middle Stone Age Artifacts from White Paintings Rock Shelter,Botswana

Abstract

Excavations conducted at the White Paintings rock shelter in the NW Kalahari Desert have uncovered seven meters of Later and Middle Stone Age deposits. Lithic microwear evidence was found on 15 artifacts representing five of the major archaeological subdivisions in the sequence and revealed work in wood, hide, and bone, as well as butchering and impact damage. Middle Stone Age points found in deposits bracketed by TL dates to between approximately 66,400 ± 6500 and 94,300 ± 9400 B.P. were of special interest because of the possible association of the Middle Stone Age with the origin of anatomically modern humans and because little, if any, micro-wear evidence has been published on Middle Stone Age points. Five out of 10 points examined revealed impact damage consistent with their use as projectiles, most likely as spear points. We present a model of the use of such points for hunting medium-sized mammals with spears, an interpretation that is largely consistent with faunal remains observed in South African cave sites.     

Taphonomic resolution and hominin subsistence behaviour in the Lower Palaeolithic: differing data scales and interpretive frameworks at Boxgrove and Swanscombe (UK)

The identification of human butchery-signatures on fauna from Lower Palaeolithic sites is well documented and readily identifiable. Such bone surface modifications have the potential to provide not only information about past hominin meat-procurement behaviour but address the wider issue of competition for resources with other carnivore species. To understand and discuss these broader issues both hominin and natural bone surface modifications must be understood and contextualised within a site-specific spatial and temporal framework. This paper presents new results from faunal analysis at two key British Lower Palaeolithic localities: Boxgrove and Swanscombe. It illustrates that different depositional environments and excavation histories have resulted in different scales and resolutions of available data and hence in varying interpretive potentials. At Swanscombe the archaeological record has been disturbed by both fluvial activity and excavation history providing a coarser-grained record of anthropogenic behaviour than previously acknowledged. Conversely, at Boxgrove, a finer-grained, higher resolution record of human behaviours has been preserved; this, combined with both an extensive and intensive excavation strategy, has allowed for a broader discussion of hominin landscape use, resource competition and meat-procurement behaviour. This paper highlights that assessing the specific depositional environment at each site is crucial to understanding Palaeolithic faunal assemblage formation and, consequently, the available data-resolution and behavioural interpretation.     

The Middle Stone Age south of the Limpopo River

Current interest in the origins of anatomically modernHomo sapiens has focused attention on early modern human remains and related archaeological materials associated with the southern African Middle Stone Age. While the anatomically modern status and a Last Interglacial or later age for the human fossils enjoy general support, issues related to the definition of the Middle Stone Age, its dating, and the interpretation of human behavior lack consensus. Available evidence suggests that the anatomically modern human skeleton appeared well before many aspects of the subsistence and symbolic behavior that characterize recent foragers and that Middle Stone Age technology persisted longer in southern Africa than its northern hemisphere counterpart.     

New radiometric ages for the Fauresmith industry from Kathu Pan,southern Africa: Implications for the Earlier to Middle Stone Age transition

The Fauresmith lithic industry of South Africa has been described as transitional between the Earlier and Middle Stone Age. However, radiometric ages for this industry are inadequate. Here we present a minimum OSL age of 464 ± 47 kyr and a combined U-series–ESR age of 542₋₁₀₇⁺¹⁴⁰ kyr for an in situ Fauresmith assemblage, and three OSL ages for overlying Middle and Later Stone Age strata, from the site of Kathu Pan 1 (Northern Cape Province, South Africa). These ages are discussed in relation to the available lithostratigraphy, faunal and lithic assemblages from this site. The results indicate that the Kathu Pan 1 Fauresmith assemblage predates transitional industries from other parts of Africa e.g. Sangoan, as well as the end of the Acheulean in southern Africa. The presence of blades, in the dated Fauresmith assemblages from Kathu Pan 1 generally considered a feature of modern human behaviour ( McBrearty and Brooks, 2000, The revolution that wasn't: a new interpretation of the origin of modern human behavior, J. Human Evolution 39, 453–563),-provides evidence supporting the position that blade production in southern Africa predated the Middle Stone Age and the advent of modern Homo sapiens.     

Akhalkalaki: The Taphonomy of An Early Pleistocene Locality in the Republic of Georgia

As part of our investigations into the potential of the Republic of Georgia for providing information on early hominin occupation of Eurasia, we report here on Akhalkalaki, a large late Early Pleistocene locality located along the lower slopes of a Miocene andesitic cone. Originally excavated in the 1950s as a palaeontological site, it was re-opened in the 1990s and stone tools were found associated with the fauna, suggesting that it is also an archaeological occurrence. Excavations in the 1950s and 1990s uncovered thousands of bones of an early Galerian fauna, including the remains of new species of Hippopotamus,Equus , and Canis (Vekua, 1962, 1987) and dominated by the remains of Equus süssenbornensis. We present the stratigraphy of the site, which together with faunal correlations and reversed paleomagnetics indicates an age most likely in the late Matuyama Chron, probably between 980,000 and 780,000 years ago. Taphonomic analysis suggests that the fauna was deposited and buried over a short time period, and was heavily modified by carnivores, but we cannot demonstrate involvement by hominins. Based on evidence of abundant krotovina (animal burrows filled with sediment) and the lack of definitive evidence for hominin modification to the bones, the stone tools at the site may have been mixed in with the older fauna. The taphonomic characteristics of the Akhalkalaki bone assemblage are not readily explained with reference to assemblage formation processes developed with actualistic studies that have been mostly conducted in Africa, including carnivore dens, predator arenas, human hunting and scavenging, mass deaths, or attritional bone deposition. Because of extreme anthropogenic modification of the present environments, the temperate setting, and the presence of mainly extinct taxa, local models based on actualistic studies cannot approximate the mammalian ecology reflected in the Akhalkalaki bone assemblage. A few comparisons are made with preliminary taphonomic observations from Dmanisi, an Early Pleistocene Homo ergaster site not far away.     

Using Pyrotechnology: Fire-related Features and Activities with a Focus on the African Middle Stone Age

Pyrotechnology was important in prehistory and has been a research topic for decades, in particular, the origins of controlled and habitual use of fire. The earliest putative evidence of fire use is from the African sites of Swartkrans (1,500,000–1,000,000 years ago) and Koobi Fora (1,500,000 years ago). In contrast, researchers working with European sites debate whether habitual use of fire occurred before 400,000 years ago. This paper provides a brief introduction to early fire use and then focuses on the African Middle Stone Age. Published evidence on fire use is available for 34 sites in southern Africa. Combustion features yield much evidence about human behavior, not only in regard to technical skills but also concerning social activities. Several activities using fire, symbolic behavior, spatial structuring, and group size in the Middle Stone Age are inferred from bone and lithic data, ash discard, site maintenance, and hearth size. The current status of knowledge on Middle Stone Age pyrotechnology demonstrates the benefits of applying new methodological approaches, facilitates comparisons with earlier and later archaeological periods, and is an important reminder of the benefits of a multidisciplinary approach.     

Ascertaining an agent: using tooth pit data to determine the carnivore/s responsible for predation in cases of suspected big cat kills in an upland area of Britain

The identification of the involvement of a particular carnivore in the modification of bone assemblages concerns a number of fields of research including archaeological and palaeontological enquiry. Taphonomy provides a methodology by which bone assemblages can be analysed and interpreted and this is more often undertaken with archaeological or palaeontological assemblages. A taphonomic analysis is undertaken here in order to determine the perpetrator of predation attacks on domestic stock from a modern-day setting. Recently reported techniques using tooth marks preserved on bone surfaces made by known carnivores are successful at determining some class sizes of predators and are used here to determine the perpetrator(s). Although a class size of carnivore is readily identified by this methodology, a particular carnivore taxon is not. Tooth morphology and dental configuration are reported here as better criteria for identifying a particular taphonomic agent. Tooth pit dimensions are used here to identify the class size of carnivores involved, and tooth morphology and cusp spacing to suggest a medium sized felid and fox as taphonomic agents. The identification of the medium-sized felid may support observations and reports of alleged “big” cat kills in the area. The study has important implications for the interpretation of fossil sites where felids may have been involved in the modification of animal carcasses but are archaeologically invisible in terms of their fossil remains.     

Burned bone in the Howieson’s Poort and post-Howieson’s Poort Middle Stone Age deposits at Sibudu (South Africa): behavioral and taphonomic implications

Despite a growing awareness of the wide range of information that can be provided by detailed analyses of burned bone from archaeological contexts, such analyses are still relatively uncommon. This paper focuses on the behavioral and taphonomic implications of burned bone from the Middle Stone Age (MSA) site of Sibudu Cave (South Africa), reporting on the analysis of a large sample (>377,000 fragments) of bone recovered from the Howieson’s Poort (HP) and post-HP MSA deposits at the site. Faunal remains were initially sorted into burning categories based on changes in color; microscopic analyses focused on the optical properties of the bone matrix (degree of preservation of the bone structure, reflectance and fluorescence) indicated that the color is a valid indicator of thermally altered bone in the Sibudu assemblage. The association of burned bone with hearths, the intensity of burning damage, and the sheer quantity of thermally altered bone suggests that the bone was not burned primarily as a result of natural fires. We propose that the high incidence of burned bone primarily reflects two types of site maintenance activities: first, the discarding of bone into fire as a means of disposing of food waste (as also argued by Cain [2005, Using burned animal bone to look at Middle Stone Age occupation and behavior. J. Archaeol. Sci. 32, 873–884], for a smaller sample of material from the post-HP and late MSA deposits at the site), and second, the incidental burning of bone on/near the surface during the periodic burning of plant-based bedding. In considering the taphonomic implications of the burned bone, we demonstrate that calcined bone is in fact more heavily fragmented than unburnt or moderately burned bone. Furthermore, cortical preservation was negatively correlated with the intensity of burning damage, which has implications for the study of surface modifications. These results indicate the importance of conducting thorough taphonomic analyses prior to making comparisons between units that show differing degrees or intensities of burning damage.     

Hunted or Scavenged Neanderthals? Taphonomic Approach to Hominin Fossils with Carnivore Damage

Carnivore damage on Neanderthal fossils is a much more common taphonomic modification than previously thought. Its presence could have different explanations, including predatory attacks or scavenging scenarios, which are both situations with important implications concerning Neanderthal behaviour. In the present paper, we analyse several Neanderthal hominin fossils from a taphonomic and forensic perspective in order to infer the nature of the modifications observed on the bone surfaces. Fossils displaying carnivore modifications from Spain, Germany, Belgium and Greece are evaluated from a taphonomic perspective for the first time in a significant sample of hominin specimens. Our results show that the materials analysed have been modified by small to large carnivores and that both attacks and strictly carnivore scavenging events can be inferred. This study also points out the importance of developing taphonomic approaches to the analysis of hominin bone surfaces, which can contribute significantly to knowledge of several aspects of Neanderthal behaviour.

Edge damage distribution at the assemblage level on Middle Stone Age lithics: an image-based GIS approach

Lithic artifacts represent the most abundant cultural remains from Middle Stone Age sites in southern Africa. Of these, pointed forms (under a variety of names), blades, and flakes have long been recognized as the three most abundant general types, and retouch on all three is rare relative to similar forms of equivalent age elsewhere. Here we offer a new technique for documenting concentrations of edge damage on an assemblage level to infer taphonomic processes and to record usewear and retouch. This approach is specifically aimed at patterning on the assemblage scale, rather than on individual artifacts. We use points from a Middle Stone Age assemblage from Pinnacle Point Cave 13B, near Mossel Bay, South Africa, to illustrate the technique. Combining GIS, rose diagrams, and polar statistics, we were able to visually and statistically summarize lithic artifacts for patterns of edge damage. For the points made on quartzite in this assemblage, edge damage was found to be significantly patterned and taphonomic causes of the damage were rejected. The technique also opens avenues for many other quantitative analyses that are either impossible or difficult with current non-visual systems of recording, such as measurements of distance, angle, and area of edge damage.     

Possible shell beads from the Middle Stone Age layers of Sibudu Cave,South Africa

Recent excavations at Sibudu Cave, KwaZulu-Natal, South Africa, uncovered an Iron Age horizon below which is a complex 3 m thick Middle Stone Age sequence with post-Howiesons Poort, Howiesons Poort, Still Bay and pre-Still Bay layers. Available OSL ages indicate that the Howiesons Poort occupation is older than 60 ky and the Still Bay older than 70 ky. Here we present the archaeological context and the taphonomic analysis of six Afrolittorina africana, three of which bear perforations, from the Still Bay and Howiesons Poort layers of this site. The single specimen from the latter cultural horizon comes from the lowermost layer attributed to this technocomplex. This and the depositional context of this layer suggest that this shell derives, as do the other five, from the Still Bay occupation layers. Taphonomic analysis of the archaeological specimens based on present day Afrolittorina africana biocoenoses, microscopic examination, morphometry, experimental perforation of modern shells, and a review of the natural agents that may accumulate marine shells at inland sites, indicate probable human involvement in the collection, transport, modification, and abandonment of Afrolittorina africana in Sibudu. If confirmed by future discoveries these shells would corroborate the use of personal ornaments, already attested at Blombos Cave, Western Cape Province, by Still Bay populations. The apparent absence of ornaments at Howiesons Poort sites raises the question of the mechanisms that have led to cultural modernity since it seems to contradict the scenario according to which cultural innovations recorded at Middle Stone Age sites reflect a process of continuous accretion and elaboration interpreted as the behavioural corollary of the emergence of anatomically modern humans.     

Faunal Assemblage Structure Suggests a Limited Impact of the Introduction of Domestic Stock on Later Stone Age Subsistence Economies in South Africa

Livestock remains appear in the South African archaeological record around 2100 years ago. However, the economic importance of domestic animals in Later Stone Age subsistence is debated. This paper adopts an approach rooted in Optimal Foraging Theory to examine if the introduction of livestock is reflected in changing taxonomic diversity of faunal assemblages. Based on the analysis of a database of 300+ faunal assemblages, it is concluded that the economic importance of livestock during the final Later Stone Age of South Africa was relatively limited.     

Bone surface modifications in zooarchaeology

Cutmarks made by stone tools, conchoidal flake scars from hammerstone percussion, carnivore tooth marks, striations from sedimentary abrasion, and other surface modifications on bones from archaeological sites constitute a crucial body of evidence for investigating the role of human behaviors and of nonhuman taphonomic processes in site formation. This paper describes the various kinds of bone surface modifications produced by humans and by nonhuman processes and assesses the current status of bone surface modification studies with regard to such issues as the need for greater analytical standardization, the selection of instruments for examining bone specimens, tactics for identifying the origins of marks on bones, and strategies for inferring human behaviors.     

First excavation of intact Middle Stone Age layers at Ysterfontein,Western Cape Province,South Africa: implications for Middle Stone Age ecology

Excavations into a coastal cliff at Ysterfontein (YFT) 1, South Africa, have revealed 2.5–3 m of stratified sands containing classic Middle Stone Age (MSA) stone artifacts, abundant mussel and limpet shells, numerous fragments of ostrich eggshell, and somewhat rarer bones from mammals, birds, tortoises, and snakes. The sands apparently filled a crevice-like, calcrete shelter, where the artifacts and animal remains accumulated partly in place and perhaps partly through slippage down the face of a dune that once stood between the site and the sea. Accelerator radiocarbon dating of ostrich eggshell places the sequence before 33,400 years ago. Artifact typology provisionally suggests that it formed after 70,000 years ago. The fauna resembles faunas from the handful of other known coastal MSA sites and contrasts with faunas from regional Later Stone Age (LSA) sites in its low diversity of coastal marine species and in the large size of its limpets and tortoises. The difference suggests that MSA people exploited local resources less intensively, probably because their populations were less dense.
