Les Iroquoiens de Droulers/Tsiionhiakwatha et le cristal de quartz

Parmi la grande quantité de témoins culturels découverts sur le site Droulers/Tsiionhiakwatha (BgFn-1), la pierre taillée et polie forme un assemblage bien modeste. Les Iroquoiens de Droulers ont habité un village semi-permanent daté du Sylvicole supérieur, plus précisément entre l’an 1430 et 1500 ap. J.-C. Ils ont fabriqués des grattoirs, des pointes de flèches, des forets, des polissoirs et des meules à mains, en plus d’outils en quartz hyalin dont la fonction n’est pas bien définie. Parmi les 3595 objets lithiques, nous trouvons 18 outils et 1085 déchets de taille en cristal, ce qui représente près de 30% du total. Le quartz hyalin fut utilisé durant la préhistoire québécoise, mais jamais en aussi grande quantité que sur Droulers. Nous présentons la chaîne opératoire du quartz hyalin, de son extraction à son rejet sur les sites archéologiques. Nous explorons également son utilisation et sa symbolique chez les habitants du village Droulers, une enquête basée sur des données archéologiques et ethnographiques des Amérindiens actuels et de ceux de la période de Contact du nord-est de l’Amérique du nord.

Un fjord, une rivière, un lac et des ruisseaux : variabilité culturelle paléohistorique sur le bassin hydrographique de la rivière Saguenay (Québec, Canada)

En archéologie, l’identification des identités culturelles spécifiques pose souvent problème. Cependant, lorsqu’on en arrive à la fin de la Paléohistoire et plus particulièrement au cours de la Protohistoire, les vestiges archéologiques trouvent alors des alliées sous la forme de sources littéraires et iconographiques qui documentent tant bien que mal la géographie humaine de l’époque. Sur le bassin hydrographique de la rivière Saguenay, quelques-unes de ces mentions révèlent que se trouvaient au cours de la Protohistoire un certain nombre de groupes distincts parmi lesquels des Iroquoiens du Saint-Laurent, des Montagnais de Tadoussac, des Kakouchacks et autres groupes du Nord. Les vestiges archéologiques des 393 sites archéologiques qui comptent au moins une composante de la Protohistoire ou de la Paléohistoire récente sur le bassin hydrographique de la rivière Saguenay ont été mis à contribution afin de déterminer si ce qui est mentionné où illustré dans les documents historiques est vérifiable du point de vue archéologique. Que ce soit les vestiges céramiques, lithiques, ostéologiques ou autres, ceux-ci ont en effet révélé certaines tendances qui ne peuvent s’expliquer que par des trames culturelles spécifiques. Après avoir constaté la présence de cette mosaïque culturelle au cours de la Protohistoire, le défi était de déterminer depuis quand celle-ci s’était mise en place et surtout d’en identifier les causes. Si l’environnement très variable qui caractérise le bassin hydrographique de la rivière Saguenay (incluant le lac Saint-Jean) a certes joué un rôle, d’autres événements ou comportements ont assurément contribué à diversifier les populations. Parmi ceux-ci, il y a la provenance des populations qui fréquentaient la rivière et ses affluents, les axes de circulations qu’ils empruntaient dans le cadre de leur cycle saisonnier, de même que le contexte des échanges qui se pratiquaient à l’échelle pan-bassin hydrographique. Tous ces aspects ont assurément joué un rôle dans la détermination de ce qu’était une population des basses terres du lac Saint-Jean versus une population du Bas-Saguenay.

Did they talk their way out of Africa?

Corballis suggests that fully vocal communication was invented by modern humans between 170,000 and 50,000 years ago. Because this new form of communication did not require hand gestures, he wondered whether this may have facilitated the development of lithic manufacture. I cast doubt on this interesting notion but offer an enhanced version that may have more potential.

Soils and their distribution on Bambouto volcanic mountain, West Cameroon highland, Central Africa

Morphological, physical and chemical studies were carried out on soils of Mount Bambouto, a volcanic mountain of the West Cameroon highland. These studies show that the soils of this region can be divided into seven groups according to Soils Taxonomy USA [Soil taxonomy: a basic system of soil classification for making and interpreting soils surveys: USDA Agriculture Handbook 436: Washington, DC, US Government Pronting Office, 1975, 754]: lithic dystrandept soils, typical dystrandept soils, oxic dystrandept soils, typical haplohumox soils, typical kandiudox soils, tropopsamment soils and umbriaquox soils. A soils map of this region at scale 1:50,000 has been drawn up, using the seven soils groups above as soil cartography units. These soils are organised into of three main categories: soils with andic characteristics in the upper region of the mountain (lithic dystrandept soils, typical dystrandept soils and oxic dystrandept soils); ferrallitic soils in the lower part of the mountain (typical haplohumox soils and typical kandiudox soils) and imperfectly developed soils (tropopsamment soils and umbraquox soils).

Mapping the human record in the British early Palaeolithic: evidence from the Solent River system

The lithic record from the Solent River and its tributaries is re-examined in the light of recent interpretations about the changing demography of Britain during the Lower and early Middle Palaeolithic. Existing models of the terrace stratigraphies in the Solent and its tributary areas are reviewed and the corresponding archaeological record (specifically handaxes) for each terrace is assessed to provide models for the relative changes in human occupation through time. The Bournemouth area is studied in detail to examine the effects of quarrying and urbanisation on collection history and on the biases it introduces to the record. In addition, the effects of reworking of artefacts from higher into lower terraces are assessed, and shown to be a significant problem. Although there is very little absolute dating available for the Solent area, a cautious interpretation of the results from these analyses would suggest a pre-Marine Isotope Stage (MIS) 12 date for the first appearance of humans, a peak in population between MIS 12 and 10, and a decline in population during MIS 9 and 8. Owing to poor contextual data and small sample sizes, it is not clear when Levallois technology was introduced. This record is compared and contrasted to that from the Thames Valley. It is suggested that changes in the palaeogeography of Britain, in particular land connections to the continent, might have contributed to differences in the archaeological records from the Solent and Thames regions.

The unsung heroes

This paper explores the roles played by local collectors, often little-known or rarely remembered, in the compilation of Britain’s Earlier (Lower and early Middle) Palaeolithic record, with reference to the work of C.E. (Charles) Bean at the Lower Palaeolithic site of Broom, and the activities of George Smith and Llewellyn and Mabel Treacher in the Middle Thames Valley. Their collecting practices, publication records, and archaeological knowledge and insights are reviewed, and their impacts assessed with reference to the activities of other contemporary collectors, and the regional archaeological records of the south-west and the Middle Thames. Their archives demonstrate that while the key sites and artefact assemblages sampled by Bean, Smith and the Treachers would not otherwise have been unknown, their work left important legacies in terms of rich artefact assemblages, site archives (Bean), and the long-term monitoring of key sites and fluvial terraces.

The British Lower Palaeolithic of the early Middle Pleistocene

The archaeology of Britain during the early Middle Pleistocene (MIS 19–12) is represented by a number of key sites across eastern and southern England. These sites include Pakefield, Happisburgh 1, High Lodge, Warren Hill, Waverley Wood, Boxgrove, Kent's Cavern, and Westbury-sub-Mendip, alongside a ‘background scatter’ lithic record associated with the principal river systems (Bytham, pre-diversion Thames, and Solent) and raised beaches (Westbourne–Arundel). Hominin behaviour can be characterised in terms of: preferences for temperate or cool temperate climates and open/woodland mosaic habitats (indicated by mammalian fauna, mollusca, insects, and sediments); a biface-dominated material culture characterised by technological diversity, although with accompanying evidence for distinctive core and flake (Pakefield) and flake tool (High Lodge) assemblages; probable direct hunting-based subsistence strategies (with a focus upon large mammal fauna); and generally locally-focused spatial and landscape behaviours (principally indicated by raw material sources data), although with some evidence of dynamic, mobile and structured technological systems. The British data continues to support a ‘modified short chronology’ to the north of the Alps and the Pyrenees, with highly sporadic evidence for a hominin presence prior to 500–600 ka, although the ages of key assemblages are subject to ongoing debates regarding the chronology of the Bytham river terraces and the early Middle Pleistocene glaciations of East Anglia.

The Epipalaeolithic (Iberomaurusian) at Grotte des Pigeons (Taforalt), Morocco: a preliminary study of the land Mollusca

Land snail middens occur widely throughout the circum-Mediterranean, particularly in the Maghreb and Libya, but are relatively understudied when compared with the better known coastal marine middens. The site of Taforalt (Grotte des Pigeons) in north east Morocco contains thick ashy deposits with considerable numbers of land snails, dating between 13,000 and 11,000 BP. The site has been excavated periodically since its discovery in 1908, but little attention has been paid to the land snail component. Recent excavations at the site as part of the Cemeteries and Sedentism Project has facilitated reinvestigation of the Iberomaurusian layers, including the upper ashy midden unit. This investigation addresses questions surrounding chronological variation in the lithic assemblage, subsistence strategies, population health and mortuary practices. Preliminary work on the land snails has identified a low species diversity in the grey series midden layers, characterised by the large edible species Alabastrina alabastrites, Helix cf aspersa, Dupotetia dupotetiana, Otala punctata and Cernuella sp, which appear to represent an abrupt intensification in the use of land snails as a food source. Significant quantities of associated plant material and animal bone suggest that land snails are part of a broader based diet which is adopted from around 13,000 BP.

Cnoc Coig: a Mesolithic shell midden assemblage

Recent work on a sample of the chipped stone from one of the late Mesolithic shell midden sites on the Inner Hebrides island of Oronsay has shown that the assemblage was created using bipolar and platform technologies, with an unexpected element of narrow blade technology shown in cores and core trimming elements, suggesting that there may have been links between this classic ‘Obanian’ assemblage and the more typical Mesolithic narrow blade technology. Findings raise questions about the relationship of settlement on the island to Mesolithic settlement rounds and to the transition to the Neolithic.

New age estimates for the Palaeolithic assemblages and Pleistocene succession of Casablanca, Morocco

Marine and aeolian Quaternary sediments from Casablanca, Morocco were dated using the optically stimulated luminescence (OSL) signal of quartz grains. These sediments form part of an extensive succession spanning the Pleistocene, and contain a rich faunal and archaeological record, including an Acheulian lithic assemblage from before the Brunhes–Matayama boundary, and a Homo erectus jaw from younger cave deposits. Sediment samples from the sites of Reddad Ben Ali, Oulad J’mel, Sidi Abderhamane and Thomas Quarries have been dated, in order to assess the upper limits of OSL. The revision of previously measured mammalian tooth enamel electron spin resonance (ESR) dates from the Grotte des Rhinocéros, Oulad Hamida Quarry 1, incorporating updated environmental dose rate measurements and attenuation calculations, also provide chronological constraint for the archaeological material preserved at Thomas Quarries. Several OSL age estimates extend back to around 500,000 years, with a single sample providing an OSL age close to 1 Ma in magnetically reversed sediments. These luminescence dates are some of the oldest determined, and their reliability is assessed using both internal criteria based on stratigraphic consistency, and external lithostratigraphic, morphostratigraphic and independent chronological constraints. For most samples, good internal agreement is observed using single aliquot regenerative-dose OSL measurements, while multiple aliquot additive-dose measurements generally have poorer resolution and consistency. Novel slow-component and component-resolved OSL approaches applied to four samples provide significantly enhanced dating precision, and an examination of the degree of signal zeroing at deposition. A comparison of the OSL age estimates with the updated ESR dates and one U-series date demonstrate that this method has great potential for providing reliable age estimates for sediments of this antiquity. We consider the cause of some slight age inversion observed at Thomas Quarries, and provide recommendations for further luminescence dating within this succession.

Micro-abrasion of flint artefacts by mobile sediments: a taphonomic approach

Fluvial redeposition of stone artifacts is a major complicating factor in the interpretation of Lower Palaeolithic open-air archaeological sites. However, the microscopic examination of lithic surfaces may provide valuable background information on the transport history of artifacts, particularly in low energy settings. Replica flint artifacts were therefore abraded in an annular flume and examined with a scanning electron microscope. Results showed that abrasion time, sediment size, and artifact transport mode were very sensitive predictors of microscopic surface abrasion, ridge width, and edge damage (p < 0.000). These results suggest that patterns of micro-abrasion of stone artifacts may enhance understanding of archaeological assemblage formation in fluvial contexts

Late persistence of the Acheulian in southern Britain in an MIS 8 interstadial: evidence from Harnham, Wiltshire

This paper presents evidence of the discovery of a new Middle Pleistocene site in central southern England, with undisturbed evidence of hominin occupation well-dated to an interstadial towards the end of Marine Isotope Stage 8, c. 250,000 BP. The site consists of a preserved remnant of a river terrace and its alluvial floodplain overlain by chalk-rich bankside deposits, all abutting a Chalk bedrock riverbank. It preserves an area of occupation with activity focused on the riverbank, complemented by occasional activity on a palaeo-landsurface developed on the surface of the alluvial floodplain. Lithic technology at the site consists almost entirely of handaxe manufacture, allowing attribution to an Acheulian industrial tradition. Mammalian and other palaeo-environmental remains are present and associated with the occupation horizons, including large mammal bones showing signs of hominin interference. Dating was based on OSL determinations on the sediments and amino acid racemisation of molluscan remains, supported by biostratigraphic indications. Besides being a rare instance of an undisturbed Palaeolithic palaeo-landscape covering several hectares, the site contributes to wider Quaternary research concerns over the ability of Middle Pleistocene hominins to tolerate colder climatic episodes in higher latitudes, and over settlement history and changing lithic industrial traditions of northwest Europe in relation to climate change and British peninsularity. It is suggested that the Harnham evidence may represent an insular population that had persisted in southern Britain since MIS 10/9, which became locally extinct during the glacial maximum 8.2 marking the end of MIS 8.
