Georgia yielded numerous middle Paleolithic sites dated of the end of middle Pleistocene and upper Pleistocene, located at the foot of the Great Caucasus barrier. several cultural groups are based on local technical trends or on behaviours coming from other areas (Near-East, Zagros, Eastern Europe). One of these, named Djruchula-Koudaro, groups sites from the Imereti and southern Ossetie areas (north and north-west of Georgia). It yields lithic assemblages with common traits, such as the proportion of blades and the use of bifacial retouches, in particular to shape the tip of elongated artefacts. If the origin of these characters leads of think to a possible link with the Near-East, another hypothesis, developed in the 1960s–1970s by Georgian researchers, proposes a relationship between the Caucasian Acheulian and the Early middle Paleolithic. In this way, the study of artefacts of reference sites of this complex (Koudaro, Tsona and Djruchula caves) has launched a discussion about the beginning of the middle Paleolithic in southern Caucasus through the laminar flaking, trying to find the part of local technical behaviours and influences born from contacts or population movements from neighbouring areas.
