Stone Age Prehistory of the Songwe River Valley, Lake Rukwa Basin, Southwestern Tanzania

This paper reports on results from survey and preliminary test excavations at MSA and LSA sites along the Songwe River in the Lake Rukwa Rift Valley of southwestern Tanzania. At IdIu22, a continuous, extensive archaeological deposit was revealed which may have both Pleistocene and Holocene components. The lithic material here shows a gradual transformation from a flake based LSA assemblage to one employing microburin techniques.Cet article discute la recherche préhistorique aux environs de la rivière Songwe, dans le vallée rift de Lac Rukwa en la sud-ouest de Tanzanie. Au gisement IdIu22, un sequence de l'âge de la pierre finale (LSA) a été découverte avec possible niveaux du Pleistocene et Holocène. Les assemblages lithiques changent graduellement dès un LSA avec outils sur les éclats, vers un LSA employant la téchnique microburin.     

The Middle and Later Stone Age faunal remains from Diepkloof Rock Shelter,Western Cape,South Africa

The faunal sample from the Middle Stone Age (MSA) and overlying Later Stone Age (LSA) deposits of Diepkloof Rock Shelter (Western Cape Province, South Africa) includes at least 40 taxa, mostly mammals, but also tortoises, snakes, birds (especially ostrich represented by eggshell), and intertidal mollusks. The LSA sample contains only species that occurred nearby historically, including domestic sheep, which LSA people introduced to the region by 1800 years ago. In contrast, like other Western Cape MSA faunas, the Diepkloof MSA sample has more species and it is especially notable for five large extralimital grazing species. These imply a greater-than-historic role for grasses in the local vegetation, particularly in the post-Howiesons Poort (latest MSA) interval where the grazers appear most abundant. Extreme fragmentation and dark-staining impedes analysis of the MSA bones, but cut-marks, abundant burning, and numerous associated artifacts suggest that people were the main accumulators. Rare coprolites imply that carnivores could have contributed some bones, and concentrations of small mammal bones, particularly near the bottom of the MSA sequence, suggest a role for raptors. Tortoise bones are common throughout the sequence, and the MSA specimens tend to be especially large, as in other MSA assemblages. The LSA specimens are smaller, probably because LSA human populations were denser and preyed on tortoises more intensively. The most surprising aspect of the Diepkloof assemblage is its marine component. The coast is currently 14 km away and it would have been even more distant during much of the MSA when sea levels were often lower. Intertidal mollusks, particularly black mussels and granite limpets, are concentrated in the LSA and in the Late and Post-Howiesons Poort layers. Only LSA shells are complete enough for measurement, and the limpets are small as at other LSA sites. The implication is again for more intense LSA collection by relatively dense human populations. Both the LSA and MSA deposits also contain bones of shorebirds and Cape fur seals. Whale barnacles and occasional dolphin bones indicate that MSA people scavenged beached cetaceans.     

Prepared core reduction at the site of Kudu Koppie in northern South Africa: temporal patterns across the Earlier and Middle Stone Age boundary

Kudu Koppie is a stratified late Earlier Stone Age and Middle Stone Age archaeological site located in the northern Limpopo Province of South Africa. The prepared core reduction strategies are described and temporal trends across the ESA–MSA boundary are presented. The prepared cores and endproducts of Kudu Koppie suggest that both the late ESA and MSA toolmakers employed the Levallois Volumetric Concept, but they often exploited a nodule's natural convexities and form. The MSA toolmakers used a greater variety of prepared core methods and more intensively exploited cryptocrystalline and microcrystalline nodules, the scarcity of which may have resulted in a more “formalized” application of the Levallois Volumetric Concept. These observations are considered within the context of human behavioural evolution.     

Introduction to the project and excavation of Diepkloof Rock Shelter (Western Cape,South Africa): a view on the Middle Stone Age

This introduction presents the background to the present research project at Diepkloof Rock Shelter, initiated in 1998. It is followed by a series of original papers that were presented in November 2010 at the join 13th PAA Congress (Panafrican Association of Prehistory and Associated Disciplines) and 20th conference of SAfA (Society of Africanist Archaeologists) at the University Cheikh Anta Diop in Dakar (Senegal). These papers were presented in a “Symposium on the MSA sequence of Diepkloof Rock Shelter: a view on the cultural evolution of southern African modern humans” organized by Pierre-Jean Texier, Guillaume Porraz, John Parkington and Jean-Philippe Rigaud. This series of papers is a first attempt at a multidisciplinary reconstruction of the way Middle Stone Age people inhabited the site of Diepkloof and the way they interacted with their environment. The resultant narrative outlines artifactual change through the sequence and discusses the factors that might underlie it.     

Technological change in the Earlier and Middle Stone Age of Kalambo Falls (Zambia)

This paper reviews data on technological change in the manufacture of stone tools from the Earlier Stone Age (ESA) to Middle Stone Age (MSA including Sangoan) deposits at Site A, Kalambo Falls, Zambia. Data on flake and tool morphology, dimensions, and raw material are discussed It is concluded that there is little change, at this site, in the basic techniques of blank production or the attributes of the blanks produced from the ESA to the MSA. The only marked change to occur is the loss of large cutting tools (hand axes, cleavers) and their replacement by heavy-duty forms (core axes, picks). It is hypothesized that this change marks a decline in portability as a factor in the design of large edge tools.

Résumé Cet article donne un compte rendu des donnés sur la change technologique dans la fabrication des outils lithiques en les dépôts du Earlier Stone Age (ESA) jusqu'a la Middle Stone Age (MSA, qui comprit la Sangoan) au gisement A, Kalambo Falls, Zambia. Des donnés sur la morphologie, les dimensions et les matériaux des éclats et des outils sont examinées. Il est inféré qu'il y a peu de changement, à ce gisement, dans le techniques élémentaires de la fabrication des supports ou dans les attributs des supports taillés du ESA jusqu'a MSA. Le seule change qui se présent ç'est la perte des gros outils pour couper (bifaces, hachereaux) et leur remplacement par des formes plus substantiels (core axes, pics). On fait l'hypothèse que ce changement indique une déclin de portabilité comme facteur dans le dessein des outils avec des grands tranchants.

     

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.     

Bedding, hearths, and site maintenance in the Middle Stone Age of Sibudu Cave, KwaZulu-Natal, South Africa

Micromorphological analysis of sediments from the Middle Stone Age site of Sibudu Cave, KwaZulu-Natal, South Africa, provides a high-resolution sequence and evidence of site formation processes of predominantly anthropogenic deposits. This methodology allows for a detailed interpretation of individual anthropogenic activities, including the construction of hearths and bedding and the maintenance of occupational surfaces through the sweep out of hearths and the repeated burning of bedding. This analysis also provides a context for evaluating other studies at the site relating to magnetic susceptibility, paleobotany, paleozoology, anthracology, and studies of ochre.     

Ojakly: A Late Bronze Age mobile pastoralist site in the Murghab Region,Turkmenistan

Abstract

Excavations at Ojakly (site 1744) in the Murghab alluvial fan in Turkmenistan mark the first systematic collection of archaeological materials related to Bronze Age mobile pastoralists in the region, and the earliest evidence to date of their occupation patterns, subsistence practices, and ceramic production activities. Because the appearance of mobile pastoral groups in the Murghab during the Late Bronze Age (ca. 1950–1500 b.c.) is traditionally associated with significant changes in regional sociopolitical structures, these data are important for establishing local strategies of and the relationship between sedentary agricultural and mobile pastoral populations. Here, we present ceramic, faunal, archaeobotanical, and lithic data that force us to reconsider the traditional sedentary-mobile dichotomy. Specifically, we find that while the subsistence economies are distinct at urban and non-urban sites, the ceramic production and trade interactions are significantly intertwined and more complex than previously acknowledged for this time period. Additionally, the presence of a ceramic kiln at Ojakly (Turkmen for “place with kiln”) containing unfired ceramics of a type typically associated with sedentary farmers in the Bronze Age Murghab suggests the transfer of technical knowledge between groups who nevertheless maintained distinct material cultural identities. Ojakly provides important new data about coexisting economies in the Late Bronze Age Murghab that can productively unsettle traditional notions of dominance, control, and polarization in sedentary-mobile interactions.     

Source provenance of obsidian artifacts from the Early Stone Age (ESA) site of Melka Konture,Ethiopia

The source provenance of 10 Early Stone Age artifacts from the localities in Melka Konture has been determined by EDXRF. Results show that the early to mid-Pleistocene makers of the artifacts derived the raw material from a source located in their proximity, supporting the previously proposed short distance transport of raw material for the time period.     

Processing ochre in the Middle Stone Age: Testing the inference of prehistoric behaviours from actualistically derived experimental data

The increase in the presence of ‘ochre’ in African Middle Stone Age contexts has been employed, together with changes in human biology and behaviour, to support the hypothesis that ‘modern’ cognitive abilities arose in Africa. The consistent exploitation of ochre is interpreted as evidence for colour symbolism, a proxy for the origin of language and a defining aspect of ‘modern’ human behaviour. That humans attached considerable symbolic value to red ochres in particular is illustrated by ethnographic examples. Research has shown that wear patterns indicative of abrasive processing methods prevail, but many archaeological specimens also exhibit wear traces not derived from grinding or scraping alone. Building on former research, I present here the results of an experimental study devised to infer the methods employed to extract powder from ochre during the African Middle Stone Age. The prospect of ascertaining at least some of the likely uses to which ochre may have been put, is also explored. I conclude that functional data derived from actualistic experiments can be used to enhance our understanding of some aspects of prehistoric behaviour.     

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.     

An experimental micromorphological investigation of bedding construction in the Middle Stone Age of Sibudu,South Africa

We conducted experiments to compare the micromorphological signatures of modern burnt sedge and grass bedding to laminated layers of carbonized material and phytoliths in Middle Stone Age deposits at the shelter, Sibudu. The experiments were designed to clarify the formation processes associated with the laminated layers and to investigate whether these previously identified layers of bedding were deliberately burned or not. The results indicate that the laminated layers were most likely produced by human activity related to the construction, maintenance and burning of bedding. Furthermore, our experiments demonstrate that large volumes of vegetal material could have produced the relatively thin, archaeological deposits of burnt bedding.     

An empirical test of the relative frequency of bipolar reduction in Beds VI,V, and III at Mumba Rockshelter,Tanzania: implications for the East African Middle to Late Stone Age transition

Mumba Rockshelter, Tanzania, is the only East African site spanning a continuous record of more than 100,000 years, including the Middle Stone Age (MSA) to Late Stone Age (LSA) Transition. Rather than examine the presence or absence of traditional markers of “behavioral modernity”, we have endeavored here to respond to the calls of Shea (2011) and Basell (2008) by examining the proportional similarity of a trait present throughout the MSA–LSA sequence at Mumba Rockshelter: the bipolar technique of lithic reduction. We use a quantified, experimentally derived proxy to track the relative amount of bipolar percussion among Mumba's Beds VI, V, and III, namely, waste shatter. Our examination of Mehlman's previously unanalyzed collections from Mumba demonstrates that in terms of bipolar production Bed V is statistically indistinguishable from the Late Stone Age (LSA) Bed III, but significantly different from the Middle Stone Age (MSA) Bed VI. Given that Bed V dates to 56.9 ± 4.8 − 49.1 ± 4.3 ka cal BP, this result is consistent with other evidence that the origins of the LSA in East Africa began well before 40 kya, and that Mumba Bed V represents one of the earliest manifestations of the LSA in East Africa. We conclude with a discussion of factors that may have influenced the increased dependence of bipolar production at the site.     

Engraved ochre from a Middle Stone Age context at Klein Kliphuis in the Western Cape of South Africa

This paper reports on a piece of engraved ochre recovered from a Middle Stone Age context at the rock shelter site of Klein Kliphuis (Western Cape, South Africa). The ochre was associated with a mixed assemblage of Howiesons Poort and post-Howiesons Poort MSA artefacts, suggesting that it is substantially younger than similar finds at Blombos Cave. The implications of the find for arguments concerning the nature of Late Pleistocene behavioural evolution are discussed.     

A Late Iron Age Boat‐Grave from Petersdal,Denmark

In 1921 a secondary grave was excavated in a Bronze Age burial‐mound on the island of Amager in the strait of Øresund between Denmark and Sweden. Recently the material was examined in detail and the result is presented here. This grave proved to be one of the few Late Iron Age boat‐graves in South Scandinavia. The boat, only preserved through a pattern of clench‐nails, was 10–12 m long. It contained traces of grave‐goods: sword, spear, riding‐gear, bucket and chest, but no trace of a body survived. The grave is contextually dated to the first half of the 8th century. © 2012 The Author     

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.     

Use-wear analysis of obsidian artifacts from Later Stone Age shell midden sites on the Red Sea Coast of Eritrea,with experimental results

This paper presents results of use-wear study on lithic artifacts from two Later Stone Age sites (Gelalo and Misse) on the Red Sea Coast of Eritrea. The sites produced large quantities of lithic artifacts in association with mollusk shells and ostrich eggshell beads, but it is unclear if all the stone tools were required for bead and mollusk shell processing. The study involved recording of microfracture damage traces in order to infer the use-material and the manner in which the artifacts were used. A large percentage of the analyzed samples from Gelalo and Misse preserve wear patterns suggestive of human use. The diagnostic wear types include: (1) dense step, snap (crushing) and hinge fractures typically confined on the working edges, and (2) feather scars organized in a scalar manner visible on the ventral and dorsal surfaces of the active parts. The observed damage patterns suggest cutting and engraving medium to hard materials. The evidence is incomplete for more generalization about the specific activities carried out at the sites. A brief experimental study involving ostrich eggshell drilling, oak twig sawing and bark scraping, meat slicing, and mollusk shell sawing and drilling was carried out to aid interpretation of wear features observed on the archaeological specimens. Wear traces produced by sawing mollusk shell and oak wood showed close affinity to those observed on the archaeological specimens. The study contributes important information about early Holocene site use on the Red Sea Coast of Eritrea. The close association of used lithic artifacts, symbolic objects (beads) and broken shell remains indicates that the sites were habitation areas.     

Levallois Lithic Technology from the Kapthurin Formation,Kenya: Acheulian Origin and Middle Stone Age Diversity

The earliest fossils of Homo sapiens are reported from in Africa in association with both late Acheulian and Middle Stone Age (MSA) artifacts. The relation between the origin of our species during the later Middle Pleistocene in Africa and the major archaeological shift marked by the Acheulian-MSA transition is therefore a key issue in human evolution, but it has thus far suffered from a lack of detailed comparison. Here we initiate an exploration of differences and similarities among Middle Pleistocene lithic traditions through examination of Levallois flake production from a sequence of Acheulian and MSA sites from the Kapthurin Formation of Kenya dated to ∼200–500 ka. Results suggest that MSA Levallois technology developed from local Acheulian antecedents, and support a mosaic pattern of lithic technological change across the Acheulian-MSA transition.Les premiers restes fossiles d’Homo sapiens sont rapportés d’Afrique aussi bien à des avec des outillages de l’Acheuléen final que du Middle Stone Age (MSA). La relation entre l’origine de notre espèce au Pléistocène moyen final d’Afrique et le changement majeur marquée par la transition Acheuléen-MSA est par conséquent un moment clé de l’évolution humaine qui a manqué jusqu’ici d’analyses comparatives détaillées. Nous nous proposons ici de commencer à explorer les différences et les similarités qui peuvent se faire jour au Pléistocène moyen dans les traditions techniques à l’examen des productions à éclats Levallois, dans une séquence de sites acheuléens et MSA de la formation de Kapthurin (Kenya), datée de 200–500 ka. Les resultants obtenus suggèrent que la technologie Levallois MSA s’est développée sur ce substrat acheuléen et renforce cette perception que l’on peut avoir d’une mosa?que de changements technologiques jalonnant la transition Acheuléen-MSA.     

Ochre resources from the Middle Stone Age sequence of Diepkloof Rock Shelter,Western Cape,South Africa

Although no paintings are associated with archaeological contexts before the end of the Middle Stone Age, hundreds of ochre pieces were discovered on numerous southern African sites suggesting a lasting tradition of ochre use. The variability and the significance of ochre exploitation remain however poorly documented. The MSA site of Diepkloof Rock Shelter (Western Cape Province, South Africa) offers an ideal opportunity to discuss questions of ochre procurement, processing, and use over a long sequence. This study develops an original methodology based on observations on one hand, and SEM-EDS, XRD and Raman spectrometry analyses on the other hand. By comparing raw materials with our geological database, we show that some iron-rich raw materials were collected more than 20 km from the site. Such long-distance procurement combined with other elements of the overall context suggests a planning of procurement. One main chaîne opératoire based on grinding was identified at Diepkloof. In comparison with other South African sites, we observed no evidence for use as loading agent in adhesives. We conclude that ochre use may follow regional cultural patterns.     

Behavioral ecological models of lithic technological change during the later Middle Stone Age of South Africa

This paper examines changes in the organization of lithic technological systems during the later Middle Stone Age (MSA) of South Africa. Using principal components analysis (PCA), the study looks at the lithic data from two important South African MSA sites: Blombos Cave and Klasies River Mouth. The paper uses PCA to describe the transition to (1) the biface-dominated Still Bay industry at Blombos Cave and (2) the microlithic Howiesons Poort industry at Klasies River Mouth. Based on these analyses, the paper offers a synthetic scenario of the emergence of the Still Bay industry from earlier MSA industries, closely followed by the dramatic transition to the Howiesons Poort. Using a few principles of tool design and behavioral ecological models derived from the study of modern foragers, the paper suggests that the Still Bay came about as the result of deteriorating environmental conditions at the beginning of Oxygen Isotope Stage 4, which caused resources to become scarce and more widely distributed. The study proposes that the bifacial point strategy of the Still Bay was a response to wider mobility patterns and increased movement away from lithic raw material sources. The paper then suggests that Howiesons Poort emerged as information sharing strategies improved, and resources in the environment could be more efficiently targeted with more task-specific tools. The paper closes by reviewing the implications of these findings for modern human origins in South Africa.
