Mise en évidence d’un changement climatique dans le site pléistocène inférieur d’El Kherba (Algérie), et son possible impact sur les activités des hominidés, il y a 1,7 Ma

Abstract

[FR] Nouvellement découvert, le site d’El Kherba fait partie du complexe des sites plio-pléistocènes d’Ain Hanech (Algérie). Les fouilles archéologiques menées dans ce site ont livré une faune fossile associée à une riche industrie lithique recueillies dans trois niveaux archéologiques distincts. La faune est de type savane comprenant éléphants, hippopotames, rhinocéros, équidés, suidés, grands et petits bovidés, girafidés, carnivores, lagomorphes, et crocodiles. L’industrie lithique est oldowayenne (Mode I) similaire à celles découvertes dans les sites d’Afrique orientale. L’âge du site est estimé à 1,7 millions d’années (Ma). Un des aspects des travaux conduits à El Kherba est la reconstitution de l’écologie du site en rapport avec le comportement des hominidés. Les faunes suggèrent un paysage ouvert et sec, en particulier durant le niveau archéologique A, corroboré par les analyses des isotopes stables du carbone (δ13C) dans les carbonates pédogéniques tout au long du profil stratigraphique d’El Kherba. L’ouverture du milieu s’est accompagnée par un accroissement temporel de l’aridification qui semble avoir eu des effets négatifs sur les activités des hominidés, particulièrement durant le niveau A.

[EN] Recently discovered, the site of El Kherba is part of the Plio-Pleistocene site complex of Ain Hanech (Algeria). The archaeological excavations conducted at this site have yielded a fossil fauna associated with a rich lithic industry recovered from three distinct archaeological levels. The fauna is savanna type comprising elephants, hippopotamus, rhinoceros, equids, suids, large and small bovids, girafids, carnivores, lagomorphs, and crocodiles. The lithic industry is Oldowan (Mode I technology) similar to the one known from East African Plio-Pleistocene sites. The site is estimated to date to 1.7 million years ago (Ma). One of the research aspects undertaken at the site is the reconstruction of the prevailing ecology relative to hominid behavior. The fauna suggests an open and arid landscape, in particular during the archaeological level A, corroborated by carbon stable isotope (δC) analysis of pedogenic carbonates along the El Kherba stratigraphic profile. The open environment is correlated with an increasing temporal aridification, which seemingly impacted negatively hominid foraging activities, particularly during level A.
