Le Mode 1 en Italie entre hétérogénéité et géofacts : le cas de la redéfinition technologique de l’industrie lithique du site de Bel Poggio

In situ-produced10Be and26Al indirect dating of Elarmékora Earlier Stone Age artefacts: first attempt in a savannah forest mosaic in the middle Ogooué valley, Gabon

“…The assemblage of Elarmékora is composed of 14 artefacts (figures 2 and 3 ) presenting clear intentional anthropic modifications: all artefacts have several regular and large removals with clear negative bulbs, and the removal orientations indicate clear flaking strategies (e.g. bidirectional, unidirectional, centripetal) [ 36 ]. These artefacts were first described as Early Acheulean in [ 30 ] based on a classic typological approach.…”

The 1‐million‐year‐old quartz assemblage from Pont‐de‐Lavaud (Centre, France) in the European context

“…Natural processes and marks, clearly resulting from transportation by rivers, solifluction or gelifluction and frost weathering, are well described and helped us to distinguish marks due to natural or anthropogenic processes. Researchers have clearly described common geofact features, such as thin removal related to the natural shape of the stones, but also the lack of clear percussion points or striking platforms (Commont, ; Obermaier, ; Pei, ; Raynal et al ., , ; Raynal and Magoga, ; Niang, ; Wiśniewski et al ., ).…”

Palaeoenvironment and dating of the Early Acheulean localities from the Somme River basin (Northern France): New discoveries from the High Terrace at Abbeville-Carrière Carpentier

“…The question of geofacts and tephrafacts was raised very early on, from the beginning of the 20 th century, and various papers took the existence of natural pieces very similar to artefacts into consideration (i.e. Commont, 1909b;Obermaier, 1912;Pei, 1936;Raynal et al, 1995Raynal et al, , 1996Raynal and Magoga, 2000;Bertran et al, 2012;Niang, 2014;Wisniewski et al, 2014). The distinction between artefacts and geofacts can be difficult to establish, but all the researchers clearly describe common features for geofacts, such as thin removals connected to the natural shape of the stones and the lack of clear percussion points.…”
