Bear in Mind: Bear Hunting in the Mesolithic of the Southern Caucasus
We present new faunal data from Kotias Klde rockshelter, Republic of Georgia, where a substantial part of the faunalv assemblage consists of brown bear remains (Ursus arctos) found in clear association with Mesolithic artifacts. Bear remains are unusually well represented in comparison with other faunal assemblages from the Caucasus and Eurasia in general. The diversity of species, dominance of young individuals, full representation of skeletal elements, and skinning butchery marks indicate that bears were actively hunted. Such an endeavor of hunting denotes the complex network of relationships that linked the Mesolithic hunting societies with the animal world surrounding them.Anthropolog

30,000 Years Old Wild Flax Fibers - Testimony for Fabricating Prehistoric Linen
A unique finding of wild flax fibers from a series of Upper Paleolithic layers at Dzudzuana Cave, located in the foothills of the Caucasus, Georgia, indicates that prehistoric hunter-gatherers were making cords for hafting stone tools, weaving baskets, or sewing garments. Radiocarbon dates demonstrate that the cave was inhabited intermittently during several periods dated to 32 to 26 thousand years before the present (kyr B.P.), 23 to 19 kyr B.P., and 13 to 11 kyr B.P. Spun, dyed, and knotted flax fibers are common. Apparently, climatic fluctuations recorded in the cave’s deposits did not affect the growth of the plants because a certain level of humidity was sustained.Anthropolog

Response to Comment by Bergfjord et al.
The comment by Bergfjord et al. expresses doubts concerning the possibility of
identifying flax fibers on the basis of the morphology of their internal layers. The authors use microphotographs and descriptions of the outer layers of fibers as arguments for their claims. Morphology and structure of the outer and inner parts of fibers are radically different, and for that reason the methodological approach of Bergfjord et al. is questionable.Anthropolog
New insights into the Upper Palaeolithic of the Caucasus through the study of personal ornaments. Teeth and bones pendants from Satsurblia and Dzudzuana caves (Imereti, Georgia)
The region of western Georgia (Imereti) in the Southern Caucasus has been a major geographic corridor for human migrations during the Middle and Upper Paleolithic. Data of recent research and excavations in this region display its importance as a possible route for the dispersal of anatomically modern humans (AMH) into northern Eurasia. Nevertheless, within the local research context, bone-working and personal ornaments have yet contributed but little to the Upper Palaeolithic (UP) regional sequence’s characterization. Here we present an archaeozoological, technological and use-wear study of pendants from two local UP assemblages, originating in the Dzudzuana Cave and Satsurblia Cave. The ornaments were made mostly of perforated teeth, though some specimens were made on bone. Both the manufacturing marks made during preparation and use-wear traces indicate that they were personal ornaments, used as pendants or attached to garments. Detailed comparison between ornament assemblages from northern and southern Caucasus reveal that they are quite similar, supporting the observation of cultural bonds between the two regions, demonstrated previously through lithic techno-typological affinities. Furthermore, our study highlights the importance attributed to red deer (Cervus elaphus) by the UP societies of the Caucasus in sharing aesthetic values and/or a symbolic sphere
Upper Palaeolithic genomes reveal deep roots of modern Eurasians.
We extend the scope of European palaeogenomics by sequencing the genomes of Late Upper Palaeolithic (13,300 years old, 1.4-fold coverage) and Mesolithic (9,700 years old, 15.4-fold) males from western Georgia in the Caucasus and a Late Upper Palaeolithic (13,700 years old, 9.5-fold) male from Switzerland. While we detect Late Palaeolithic-Mesolithic genomic continuity in both regions, we find that Caucasus hunter-gatherers (CHG) belong to a distinct ancient clade that split from western hunter-gatherers ∼45 kya, shortly after the expansion of anatomically modern humans into Europe and from the ancestors of Neolithic farmers ∼25 kya, around the Last Glacial Maximum. CHG genomes significantly contributed to the Yamnaya steppe herders who migrated into Europe ∼3,000 BC, supporting a formative Caucasus influence on this important Early Bronze age culture. CHG left their imprint on modern populations from the Caucasus and also central and south Asia possibly marking the arrival of Indo-Aryan languages.This research was supported by the European Research Council (ERC) Starting Grant to R.P.

Genome-scale sequencing and analysis of human, wolf, and bison DNA from 25,000-year-old sediment
Cave sediments have been shown to preserve ancient DNA but so far have not yielded the genome-scale information of skeletal remains. We retrieved and analyzed human and mammalian nuclear and mitochondrial environmental "shotgun" genomes from a single 25,000-year-old Upper Paleolithic sediment sample from Satsurblia cave, western Georgia:first, a human environmental genome with substantial basal Eurasian ancestry, which was an ancestral component of the majority of post-Ice Age people in the Near East, North Africa, and parts of Europe; second, a wolf environmental genome that is basal to extant Eurasian wolves and dogs and represents a previously unknown, likely extinct, Caucasian lineage; and third, a European bison environmental genome that is basal to present-day populations, suggesting that population structure has been substantially reshaped since the Last Glacial Maximum. Our results provide new insights into the Late Pleistocene genetic histories of these three species and demonstrate that direct shotgun sequencing of sediment DNA, without target enrichment methods, can yield genome-wide data informative of ancestry and phylogenetic relationships
Mesolithic Hunters at Kotias Klde, Western Georgia: Preliminary Results
Abstract: The excavations at Kotias Klde, a karstic cave in the western region of the Republic of Georgia, uncovered a sequence of Neolithic layer topped by some Bronze Age remains (A1 and A2), a complex Mesolithic layer (B), and the top of layer C, tentatively recognized as late Upper Palaeolithic. The preliminary report describes the contents of the Mesolithic deposit with its particular industry, characterized by triangles of various shapes and a faunal assemblage of hunted brown bear, dated to 12,400-10,380 cal. BP.Résumé: Les fouilles conduites à Kotias Klde, une grotte karstique de l’Ouest de la Géorgie, ont permis de mettre au jour une séquence formée de quelques restes de l’âge du Bronze qui surmontent une séquence néolithique (A1 et A2), une couche complexe mésolithique (B) et le sommet d’une couche C, qui relèverait d’un Paléolithique supérieur tardif. Ce rapport préliminaire porte sur les assemblages du dépôt mésolithique daté de 12 400-10 380 cal. BP, dont l’industrie particulière se caractérise par des formes variées et par un assemblage faunique composé de restes de chasse à l’ours brun.Meshveliani Tengiz, Bar-Oz Guy, Bar-Yosef Ofer, Belfer-Cohen Anna, Boaretto Elisabetta, Jakeli Nino, Koridze Irakli, Matskevich Zinovi.

New insights into the Upper Palaeolithic of the Caucasus through the study of personal ornaments. Teeth and bones pendants from Satsurblia and Dzudzuana caves (Imereti, Georgia)
The region of western Georgia (Imereti) in the Southern Caucasus has been a major geographic corridor for human migrations during the Middle and Upper Paleolithic. Data of recent research and excavations in this region display its importance as a possible route for the dispersal of anatomically modern humans (AMH) into northern Eurasia. Nevertheless, within the local research context, bone-working and personal ornaments have yet contributed but little to the Upper Palaeolithic (UP) regional sequence’s characterization. Here we present an archaeozoological, technological and use-wear study of pendants from two local UP assemblages, originating in the Dzudzuana Cave and Satsurblia Cave. The ornaments were made mostly of perforated teeth, though some specimens were made on bone. Both the manufacturing marks made during preparation and use-wear traces indicate that they were personal ornaments, used as pendants or attached to garments. Detailed comparison between ornament assemblages from northern and southern Caucasus reveal that they are quite similar, supporting the observation of cultural bonds between the two regions, demonstrated previously through lithic techno-typological affinities. Furthermore, our study highlights the importance attributed to red deer ( Cervus elaphus ) by the UP societies of the Caucasus in sharing aesthetic values and/or a symbolic sphere
Morphological description and morphometric analyses of the Upper Palaeolithic human remains from Dzudzuana and Satsurblia caves, western Georgia
While paleoanthropologists and archaeologists agree thatwestern Georgia was used as a thoroughfare of human movements to and from the Caucasus (Pinhasi et al., 2012, 2014), the paleoanthropological fossil record of the local Middle and Upper Palaeolithic in this key region is currently limited to scant human remains. For the Late Pleistocene, the Middle Palaeolithic (MP) Georgian human fossil record consists of a partial maxilla from the site of Sakajia and some isolated teeth from the sites of Bronze Cave, Djruchula, Ortvala and Ortvale Klde, which were all classified as Neandertals (Pinhasi et al., 2012). The Upper Palaeolithic (UP) fossil record consists of a modern human tooth from Bondi cave (Tushabramishvili et al., 2012), recently dated between 39,000 and 35,800 cal. BP (calibrated years before present; Pleurdeau et al., 2016), and cranial fragments from Sakajia, dated between 12,000 and 10,000 cal. BP (Nioradze and Otte, 2000) (Supplementary Online Material [SOM] Fig. S1). Therefore, even though some authors suggest that the Caucasus represents a sort of cul de sac for Neandertal survival, and that modern humans arrived in this area much later compared to other regions (Bar-Yosef and Pilbeam, 2000), the paucity of human remains prevents any conclusive assessment. Here we report additional Upper Palaeolithic human remains from the Imereti region, western Georgia (SOM Fig. S1): two isolated teeth from Dzudzuana cave, Dzu 1 and Dzu 2 (both deciduous; Bar-Yosef et al., 2011), and one isolated tooth (SATP5-2, deciduous) and a hemi-mandible (SATP5) bearing permanent and deciduous teeth (SATP5-3 e SATP5-7) from Satsurblia cave (Pinhasi et al., 2014). In particular, the human remains from Dzudzuana cave, dated between 27,000 and 24,000 cal. BP, fill a huge gap in the Upper Palaeolithic Georgian fossil record and play an important role in the debate about modern human peopling of the Caucasus
