Introduction
Specialized in use-wear analysis of stone tools, my present research targets the variability of human adaptive systems in the scope of the dispersion of the Anatomically Modern Humans (AMHs) from the African continent to throughout Eurasia. It aims to explore the mechanisms at play between cultural adaptation and environment by studying distinct environmental backdrops and material cultural niches of Early Upper Paleolithic sequences in W. E. and of Middle Stone Age contexts in South Africa.

Article
Full-text available
In southern Africa, key technologies and symbolic behaviors develop as early as the later Middle Stone Age in MIS5. These innovations arise independently in various places, contexts and forms, until their full expression during the Still Bay and the Howiesons Poort. The Middle Stone Age sequence from Diepkloof Rock Shelter, on the West Coast of the...

In South Africa, key technologies and symbolic behaviors develop as early as the later Middle Stone Age in MIS5. These innovations arise independently in various places, contexts and forms, until their full expression during the Still Bay and the Howiesons Poort. We elaborate here on the Middle Stone Age sequence of Diepkloof Rock Shelter (South Af...

Edge convergence, which is typical for pointed tools, is a major morphological feature contributing to the definition of the African Middle Stone Age (MSA). The multifaceted character of points might be the key to their success and for their recurrent adoption by prehistoric populations. Whether MSA points represent a good proxy to identify populat...
Article
Marine food–reliant subsistence systems such as those in the African Middle Stone Age (MSA) were not thought to exist in Europe until the much later Mesolithic. Whether this apparent lag reflects taphonomic biases or behavioral distinctions between archaic and modern humans remains much debated. Figueira Brava cave, in the Arrábida range (Portugal)...
Article
Full-text available
In the past few decades, a diverse array of research has emphasized the precocity of technically advanced and symbolic practices occurring during the southern African Middle Stone Age. However, uncertainties regarding the regional chrono-cultural framework constrain models and identification of the cultural and ecological mechanisms triggering the...
Article
Bifaces dominate the Acheulean stone tools recovered during the archaeological excavation of layer X of Gruta da Aroeira, dated to 389–436 ka. Faunal remains and a human cranium were found in association with this lithic assemblage. The raw materials used are mostly quartz and quartzite cobbles available in the vicinity of the site. Technological a...
Article
Régismont-le-Haut, an Aurignacian open-air campsite, provides an occasion to investigate aspects of Aurignacian site variability that are rarely broached: (1) the relatively poorly known area connecting the Aquitaine and Mediterranean Basins, and (2) the high-resolution spatial organization of an Early Upper Palaeolithic campsite. While more diffic...

Elands Bay Cave (EBC) is a key South African site allowing discussion of technological change and adaptations that occurred from the Upper Pleniglacial to the Holocene. In 2011, we set out a new field campaign aiming to clarify the nature and chronology of the earliest Robberg occupations at the site, a technocomplex whose appearance closely relate...
Article
Full-text available
Elands Bay Cave provides the opportunity to characterize Holocene technologies and hunter-gatherers adaptations in the West Coast of South Africa. In this paper, we discuss the question of adhesives uses and manufactures by applying a biomolecular and technological analysis to three unpublished organic artefacts recovered from the 1970s excavation....
Article
Full-text available
Elands Bay Cave (EBC) is one of the key sites for the analysis of the Late Pleistocene/Holocene record in southern Africa. It typifies an area of study, the West Coast of South Africa, which benefits from a long history of research, from the 1960s until today. The 2011 project of EBC was initiated within the framework of the Middle Stone Age (MSA)...
Article
Full-text available
Southern Africa presents the best-documented Middle and Later Stone Age (MSA and LSA) records in Africa, and yet significant uncertainties still exist concerning the sequence and timing of behavioral and occupational changes in the region. A recent surge in research has provided a suite of new results that indicate more intricate and complex patter...

The Middle Stone Age (MSA) sequence of Diepkloof includes a technological phase (MSA-Jack) characterized by the selection of local rocks, the production of flakes and blades by internal hammer stone percussion, and by a typological corpus including backed pieces and ‘backed scrapers’. The intercalation of the MSA-Jack between the Early and the Inte...
Article

The Howiesons Poort (‘HP’) is characterized by a set of technological innovations that mark a rupture in the Southern African Middle Stone Age. However perspectives regarding its origin and emergence remain speculative. The recent identification of an Early HP phase at Diepkloof Rock Shelter provides the opportunity to characterize the initial stag...

Article
After nine years of excavations (three of survey 1998-1999 and 2001 and six of programmed excavations from 2003 to 2008), the site of La Picardie has delivered a major lithic collection (more than 13,000 artefacts) related to Rayssian (second phasis of french Middle Gravettien). Since the beginning, several major results have been brought through s...

The open-air site of La Vigne Brun (23-24 Ky B.P.), in the Loire valley (France), is exceptional due to well preserved fireplaces and a wide variety of stone tools. Highly similar to gravettian sites of central and Eastern Europe, La Vigne Brun is unique in Western Europe.The purpose of this paper is to present preliminary results on use-wear analy...
