The Still Bay points of Blombos Cave (South Africa)

We present the results of a technological and morphometric analysis of all the Still Bay points (n = 371) recovered from the 1993 to 2004 excavations at Blombos Cave. We have been able to reconstruct the manufacturing sequence of the bifacial points from initial shaping, by direct internal percussion, to finished morphology, by direct marginal percussion. Identifications of impact fractures and manufacturing breaks are based on comparisons with experimental and archaeological bifacial points of verified function, i.e. Paleoindian points from bison kill sites, replicates of Solutrean points mounted as spear-heads or arrowheads and shot into adult cattle, and experimental replication on local raw materials. Our analysis shows that: (a) only a minority of the points are finished forms, and that a large number of pieces are production failures, a situation known at bifacial point production sites of later ages; (b) morphometric and impact scar analyses should take into account this process and distinguish finished points from preforms and unfinished points; (c) there were at least three different kinds of raw material sources and that there is a marked increase in the frequencies of silcrete with respect to the M2 and M3 phases at Blombos; (d) three kinds of evidence prove that some of the points were hafted axially and used as spear tips; (e) production of bifacial points was a primary activity at the site but the hypothesis of intergroup exchange of Still Bay points cannot be sustained on the basis of present evidence; and (f) the Still Bay phase appears to initiate a trend to relatively rapid changes in specialized hunting weaponry and that this innovation is congruent with other innovations such as bone tools, shell beads and engraved ochre of the M1 and M2 phases at Blombos.     

Relative frequency of butchering cutmarks produced by obsidian and flint: an experimental approach

An experimental approach was used to determine how stone tool materials affect the frequency of observed cutmarks. Five whitetail deer were butchered by an expert butcher using flint and obsidian tools and the skeletons were prepared and analyzed. The authors found that the deer butchered with obsidian tools generally displayed fewer incidents of cutmarks than their flint-butchered counterparts. Consideration of this variable may prove to be important to archaeologists attempting to answer questions of specialization or when making comparisons of cutmark data between sites.     

Blade technology and tool forms in the Middle Stone Age of South Africa: the Howiesons Poort and post-Howiesons Poort at Rose Cottage Cave

It has been suggested that between 80 and 35 ka the Middle Stone Age record of South Africa reveals episodes of inventiveness and innovation, punctuated by apparent returns to more conventional technologies. One such episode is the Howiesons Poort (HP). The appearance of a range of small geometric forms, apparently used as insets in multi-component tools, has been considered as evidence of improved hunting weapons, with possible social and symbolic connotations. On the basis of evidence such as backed tool production, small blade technology, the occurrence of typical end-scrapers and burins similar to those encountered in the European Upper Paleolithic, long-distance transport of fine-grained raw materials, and non-lithic novelties, the HP is associated with increased levels of technological efficiency and with behavioral innovations that could have allowed the expansion of African populations to other regions. Yet our knowledge of HP technology and tool production is limited to the analysis of Klasies River Main site by Singer and Wymer and Sarah Wurz, and a few preliminary reports from other sites. This is why we present here a detailed technological and typological analysis of several HP and post-HP assemblages from the well-excavated, well-dated and well-stratified site of Rose Cottage. Our analysis shows: (a) that the HP blade production was a real technical innovation, but was not based on indirect percussion, as often suggested; (b) that blade production was based on the use of marginal percussion which does not occur in the blade production of the Eurasian Middle Paleolithic; (c) that the tool kit was dominated by backed pieces, but not all can be considered as hunting weapons; (d) that neither end-scrapers nor burins are typical of this industry and are no more an antecedent to the European Upper Paleolithic than the end-scrapers and burins of the Middle Paleolithic; (e) that patterns of raw material procurement do not conform to models based on evidence from Klasies; (f) that diachronic changes within the Rose Cottage sequence indicate slow, gradual abandonment of the technological style of the HP; (g) that the post-HP assemblages are of MSA character and are typologically and technologically quite similar to the European Middle Paleolithic; (h) that the lack of persistence of the HP innovations is in need of an explanation. The HP is not a monolithic entity. Implications for the symbolic interpretations of the HP phenomenon are discussed.     

The Holocene Archaeological Sequence of Shum Laka Rock Shelter (Grassfields, Western Cameroon)

Until recently the Grassfields (western Cameroon), cradle of the Bantu languages, were an unknown zone from the archaeological point of view. The excavations of Shum Laka rock shelter by de Maret and his team brought the most complete sequence in West Africa, spanning the Late Pleistocene and the Holocene. After 20 millennia of microlithic tradition (Late Stone Age), a new culture, with macrolithic tools, polishing and pottery (Stone to Metal Age), slowly developed ca. 7000 B.P. onwards. From this early period on, forest hunting was associated with the exploitation of Canarium schweinfurthii. Around 4000 B.P., an industry with waisted axes, blades, and pottery had emerged. With a striking technological continuity, this culture survived throughout the Iron Age. Increasing importance and diversity of trees exploited through the Stone to Metal Age and the Iron Age suggests arboriculture. Regional comparisons show that, between 5000 and 2500 B.P., an original culture developed in the Grassfields and the Cross River basin.Jusqu'à récemment, les Grassfields (Cameroun occidental), berceau des langues bantoues, étaient inconnus d'un point de vue archéologique. Les fouilles de l'abri de Shum Laka par de Maret et son équipe permirent d'établir la plus complète séquence d'Afrique occidentale, embrassant la fin du Pléistocène et l'Holocène. Après 20,000 millénaires de traditions microlithiques (Age de la Pierre Récent), une nouvelle culture, caractérisée par l'apparition d'outils macrolithiques, de polissage et de poterie (Age de la Pierre au Métal), se développe lentement à partir de 7000 B.P. Dès le début, la chasse en forêt est associée à l'exploitation de Canarium schweinfurthii. Vers 4000 B.P. une industrie avec haches à gorge, lames et poterie a émergé. Dans une continuité technologique surprenante, cette culture survivra à l'Age du Fer. L'arboriculture est suggérée par l'importance et la diversification des arbres exploités durant l'Age de la Pierre au Métal et l'Age du Fer. Des comparaisons régionales montrent que, entre 5000 et 2500 B.P., une culture originale se développe dans les Grassfields et le bassin de la Cross River.     

The Early Later Stone Age in East Africa: Excavations and Lithic Assemblages from Lukenya Hill

The site of Lukenya Hill, Kenya, is one of the richest Later Stone Age (LSA) sites in East Africa. Its sequence documents the increasing manufacture of microlithic tools, one of the hallmarks of hunter–gatherer behavioral modernity (Bar-Yosef and Kuhn, 1999). This paper presents results of excavations at the LSA site of GvJm62, Lukenya Hill, and analysis of site formation processes on this inselberg rock shelter. It examines lithic assemblages from GvJm62 and four other Pleistocene-dated LSA sites at Lukenya Hill. Differences in raw material use, typology, and chronology indicate that there are three different kinds of LSA industries in the sampled sites at Lukenya Hill. Changes in technology, activities, and land use patterns can explain the differences among these three industries. The Lukenya Hill sequence is compared with other East African LSA industries.Le gisement de Lukenya Hill en Kenya est un des gisements les plus riches du type Paleolithique Superieure en Afrique de l'Est. La sequence demonstre l'éxistence et ensuite le fréquence des outils microlithiques. Cet article présent les résultats des fouilles du gisement de GvJm62 à Lukenya Hill et présent un étude des methodes de formation du gisement. On examine les outils lithiques de GvJm62 et quatre autres gisements à Lukenya Hill. Les differences des types des matières premiers, de la chronologie, et des types d'outils suggèrent qu'il y a trois types d'industrie à Lukenya Hill. On peut expliquer ces differences par changements en la technologie, les activités et les modèles de l'utilisation de la terre. La séquence à Lukenya Hill est comparée avec les autres industries Est Africain.

What Is a Hunter-Gatherer? Variation in the Archaeological Record of Eastern and Southern Africa

This article reviews the recent history of the archaeology of African hunter-gatherers, focusing on debates around the origins of modern humans and the destiny of hunter-gatherers with the advent of food production. African archaeologists are developing an increasing appreciation for the diversity of African hunter-gatherer societies. Understandings of hunter-gatherers based primarily on ethnography are being successfully challenged and extended.     

Blind tests shed light on possibilities and limitations for identifying stone tool prehension and hafting

Prehensile wear has never formed the focus of a blind test in microwear studies and doubts remain about the formation, identification and interpretation of diagnostic prehension and hafting wear. The results of the presented blind tests demonstrate that prehension and hafting traces do form and that their formation is sufficiently systematic and patterned to allow valid and reliable interpretations. A combined approach, involving macroscopic, low power and high power analyses, is suggested as the most meaningful approach for consistent inferences.     

The technology of Stone Age colonization: an empirical,regional-scale examination of Clovis unifacial stone tool reduction,allometry, and edge angle from the North American Lower Great Lakes region

There is now broad consensus that the appearance of Clovis in Northeastern North America (Great Lakes, New England) represents a colonization pulse into recently deglaciated landscapes. Due to the increased resource uncertainty that comes with colonizing unfamiliar landscapes, it was hypothesized that the majority tool component of Clovis assemblages, unifacial stone tools, should have been knapped on tool blanks possessing the design properties of longevity and functional flexibility to facilitate exploration mobility and guard against the absence of toolstone sources in the new landscape. These properties are optimized by large, flat flakes, possessing large surface area relative to flake thickness. Since discarded and, at times, exhausted unifacial stone tools do not preserve the original dimensions of the blank upon which they were created – necessary items for a true test of blank morphology selection – this study presents a set of predictions for inferring whether Clovis unifacial stone tool blanks were selected for the properties of longevity and functional flexibility based on evidence that Clovis people actually capitalized on those properties. Due to the nature of Clovis unifacial stone tools, tool size was of necessity used as a proxy for tool reduction, on the grounds that smaller tools are more likely to have been resharpened than larger tools, at least in the case of unifacial flake tools. The results showed that less resharpened tools possessed flatter, less spherical shapes than the more resharpened tools, which possessed more globular, spherical shapes, suggesting Clovis foragers exploited the retouch potential afforded by the larger, flatter blanks. Edge angles showed no relationship with tool reduction, suggesting that Clovis foragers exploited the functional flexibility afforded by flatter blanks by adjusting the edge angle to be either higher or lower as needed. These results are consistent with the notion that human colonizers, who did not know the abundance or location of stone outcrops prior to settling an unfamiliar territory, not only “geared up” before leaving a stone source, but geared up as efficiently as possible by carefully selecting the blanks they chose to carry. Broader implications for such careful unifacial stone tool blank selection are discussed.
