Nouvelles observations sur le gisement paléolithique supérieur de Belloy-sur-Somme (Somme)

Abstract

Le gisement paléolithique supérieur de Belloy-sur-Somme, situé dans la vallée de la Somme à une quinzaine de kilomètres au nord-ouest d'Amiens, a été étudié par V. Commont au début du siècle. Il fait l'objet de nouvelles recherches depuis 1984. Trois occupations attribuables au Paléolithique supérieur récent et final ont été reconnues au sommet de la séquence limoneuse de la très basse terrasse de la Somme. Ces différentes occupations font de ce gisement un site de référence pour le Nord de la France à la fin des temps glaciaires. Les principales données concernant les occupations du Paléolithique supérieur final sont ici présentées. Le Magdalénien final sera traité dans un article séparé.

Estimation of soil weathering stage and acid neutralizing capacity in a toposequence Luvisol–Cambisol on loess under deciduous forest in Belgium

“…Where the water flow was substantial, local erosion occurred and the sediment accumulated in the low‐lying areas. This has been illustrated through the observation of loessic colluvial or alluvial deposits during the Middle Dryas (approximately 11 800–11 600 years bp ) reported by Fagnart (1992) in the Somme valley, France. In the Bertem toposequence, the pre‐Holocene erosion would also explain satisfactorily the development and the thickness of the E horizon (16–26 cm) in the eroded materials on the slope.…”

A Reindeer antler or ‘Lyngby’ axe from Northamptonshire and its context in the British Late Glacial

“…A'long blade' component is certainly present at Sproughton, Suffolk (Wymer 1976) and Avington VI in the Kennet Valley, Berkshire (Barton and Froom 1986). The same combination of artefacts is also known from northern France amongst what have been termed industries a pieces machurees (Fagnart 1992, fig. 17).…”

“…The lithic material from Avington VI differs from that of other 'Ahrensburgian' sites because slender microlithic backed bladelets are present in the collection. It remains to be established whether these truly belong with the 'large' and 'giant' blades, the bruised blades and large cores, or whether, as at Belloy (Fagnart 1992), other older occupation traces wait to be isolated. CONCLUSION The Lyngby axe from Earls Barton can be regarded as part of a relatively small but distinctive group of British archaeological material the characteristics of which can be matched elsewhere in north-west Europe.…”
