The environmental contexts of early human occupation of Georgia (Transcaucasia)

The hominid mandible and a third metatarsal found in Dmanisi (Republic of Georgia) are accompanied by a rich faunal assemblage and a core-chopper stone tool industry. The mandible represents a somewhat isolated morphological type of Homo erectus that appears, given the combination of its primitive and advanced traits and specific dental morphology, to be a forerunner of both late H. erectus and early archaic H. sapiens. The faunal assemblage mostly consists of Villafranchian mammals, with the majority of the species assigned to an early phase of the Upper Villafranchian (Late Villanian and Early Biharian). Faunal and paleobotanical evidence as well. as the depositional nature of the site indicate that hominid occupation took place in a mosaic environment of open steppe and gallery forests. Both the concentration of resources and the warm climatic conditions in the Dmanisi region at the beginning of the early Pleistocene were favorable for hominid occupation. It is possible that hominids reached the Caucasus through the Levantine corridor, and that the environment of this region allowed them to establish a stronghold and later colonize adjacent areas.
