Variations paléoenvironnementales au sein de l'Unité Archéostratigraphique G (UA G) de la Caune de l'Arago (Tautavel, France) : apport des paléocommunautés de rongeurs
The Archaeostratigraphic Unit G (UA G), located at the base of the stratigraphic ensemble CIII of the Caune de l’Arago infilling, dated to 438± 31 ka and correlated to the isotopic stage 12, delivered numerous human remains attributed to Homo erectus tautavelensis, as well as abundant fauna and lith...

The Archaeostratigraphic Unit G (UA G), located at the base of the stratigraphic ensemble CIII of the Caune de l’Arago infilling, dated to 438± 31 ka and correlated to the isotopic stage 12, delivered numerous human remains attributed to Homo erectus tautavelensis, as well as abundant fauna and lithics. At the top of the UA G it is possible to observe a good representation of the species living in open and cold environments (Praeovibos priscus and Rangifer tarandus in particular) whereas the species living in closed and temperate environment (particularly Cervus elaphus and Dama sp.) predominate at its base. These structures of faunal communities, said “non-analogous”, are also observed for the associations of micromammals, providing a diversified palaeocommunity and represented by taxa with very distinct ecological affinities.
