In southern Africa, the use of gravel outcrops has been recorded at a range of Earlier Stone Age sites, and this raises questions about the diversity of raw material sourcing practices adopted by hominins. To assess the existence of sourcing strategies, this study details a new morphometric analysis method that investigates the influence of pebble and cobble shape at two Acheulean case-study sites: Dungo IV (Benguela Province, Angola) and Penhill Farm (Eastern Cape Province, South Africa). Since these assemblages present frequent pebble and cobble artefacts, we investigate these to identify raw material blank properties to then establish whether these properties were intentionally selected for. To do so, we analyse each archaeological sample separately via a technological and morphometrical approach and then compare them with geological samples obtained during fieldwork survey. Overall, these two case studies provide some illustration of variable selection strategies within the southern African coastal plain.

Despite its strategic location within the continent, Central Africa is rarely integrated into the reconstruction of population dynamics during the Middle Stone Age (MSA) of Africa, especially in terms of the emergence, diffusion and behavioural patterns of Homo sapiens. However, hundreds of sites have been discovered in Central Africa during the 20th century and attributed to the Lupemban, one of the main MSA technological complexes of the region. This complex is mainly characterised by typological criteria based on the numerous bifacial pieces found in the Congo Basin and interpreted as an adaption to the rainforest environment. Most of these Lupemban assemblages have not been studied for decades and thus it is particularly difficult to assess their diversity. This paper presents a detailed combined morphometrical approach (linear measurements and indices, Log Shape Ratio, Elliptic Fourier Analysis) to take a fresh and rigorous look at the Lupemban bifacial tools. We discuss the comparison of different morphometrical approaches to deal with “old” collections for which contexts, particularly chronological ones, are partially missing. We present the results of this approach on three assemblages of bifacial pieces gathered in the 1930s and late 1960s. We quantify their variability and discuss not only their homogeneity but also the variation of a Lupemban hallmark, namely the “Lupemban point”.

Alors qu'une grande partie du continent africain révèle d'importants vestiges du Middle Stone Age témoignant de l'émergence et de la diffusion d'Homo sapiens sur le continent dès le Pléistocène moyen, les connaissances sur le rôle du Bassin du Congo dans les dynamiques de peuplements continentales et régionales restent pauvres. La rare préservation des vestiges osseux et de la stratigraphie sur les sites pléistocènes de plein-air est souvent considérée comme le principal écueil. Mais, près d'un siècle après la création du premier faciès culturel préhistorique régional de l'Afrique centrale, la Tumbakultur, le bilan historiographique du Middle Stone Age du Bassin du Congo suggère que la nomenclature, la diversité méthodologique des approches sur les pierres taillées et la fragmentation des savoirs et des collections préhistoriques sont autant de facteurs à prendre en compte afin de déployer de nouvelles perspectives de recherches en Préhistoire.

The relationship between Earlier Stone Age (ESA) hominins and the southern African coastal environment has been poorly investigated, despite the high concentration of open-air sites in marine and fluvial terraces of the coastal plain from c. 1Ma onward during the Mid-Pleistocene Transition. Southern Africa provides some of the earliest evidence of coastal subsistence strategies since the end of the Middle Pleistocene, during the Middle Stone Age (MSA). These coastal MSA sites showcase the role of coastal environments in the emergence and development of modern human behaviors. Given the high prevalence of coastal ESA sites throughout the region, we seek to question the relationship between hominins and coastal landscapes much earlier in time. In this regard, the +100 m raised beaches of the Benguela Province, Angola, are key areas as they are well-preserved and contain a dense record of prehistoric occupation from the beginning of the Middle Pleistocene, including sites like Dungo, Mormolo, Sombreiro, Macaca and Punta das Vacas. Accordingly, this paper provides a critical review of the coastal ESA record of southern Africa and a detailed presentation of the Dungo IV site, through a qualitative technological analysis coupled with a quantitative inter-site comparison with contemporary southern African coastal plain sites. Through our detailed technological analyses, we highlight the influence of coastal lithological resources on the technical behaviors of hominin groups, and we propose the existence of a “regional adaptive strategy” in a coastal landscape more than 600 000 years ago. Finally, we argue for the integration of coastal landscapes into hominins’ territories, suggesting that adaptation to coastal environments is actually a slower process which begins with “territorialization” well before the emergence and development of Homo sapiens.
