28 Documenta Praehistorica XLVII (2020) Introduction The Kobuleti site is located in western Georgia (Fig. 1). This area belongs to one of the regions of the South Caucasus, situated by the Black Sea. This area played an important role in the development of the neolithization processes in Eastern Europe. The South Caucasus used to be a transit region through which the Neolithic innovations from the Near East were transmitted. Recently a large number of Early Holo- cene sites on the territory of Armenia and Georgia has been studied, and their materials indicate that their culture originated in the areas of primary neo- lithization (Arimura et al. 2009; Kadowaki et al. 2016). Concurrently, we observe that the process of migra- tion to Caucasus from Anatolia, Iran, and Iraq had begun long before the development of the Neolithic culture. The Trialetian Kotias Klde complex (Meshve- liani et al. 2007) gives us some evidence of the mi- gration from Anatolia. Its complex is similar to Hal- Kobuleti site> the evidence of Early Holocene occupation in Western Georgia Guram Chkhatarashvili 1, Valery Manko2 1 Department of Stone Age, Ajara Museum, Batumi, GA gurami.chxa87@yahoo.com 2 Institute of Archaeology of National Academy of Sciences of Ukraine, Kyiv, UA valery_manko@yahoo.com ABSTRACT – In the 1970–1980s the fieldwork in the Kobuleti Village revealed more than 30 000 ar- tefacts associated with the Early Neolithic period. However, recent fieldwork in Kobuleti, carried out by the authors, demonstrated that the cultural layers of the site belong to the Early Holocene period. The stone industry of the site has indicated the use of blank removal. The conic and bullet shaped cores were used in order to get bladelets and microblades. The complex of flint and obsidian tools consists of numerous retouched blades, bladelets and microblades, burins, and chisels. There are series of bladelets and microblades with abrupt retouch. Generally speaking, the typology of the complex indicates that the site was used as a temporary hunting camp.

The authors of this article studied an area of 32m2. The geographical position of Kobuleti The Kobuleti site is located on the territory of the Kobuleti Village in Adjara (Georgia), on a cape on the left bank of the Kintrishi River. The cape, sur- rounded by two riverbeds, occupies an area of about 50x50m, towering 16–25m above the river level. The cape is situated 60m a.s.l. The cape is composed of basalt rocks (Fig. 2), and only its upper part is as- sociated with sediments of the paleo-soils layer. Geographically, the site is situated on the Colchis Plain, which occupies a part of the coastal territory. The Kintrishi River flows along the southern part of the plain, at the very boundary with the foothills. Currently, the Colchis Plain belongs to the subtro- pical climate zone, but this does not mean that the climate was the same at the beginning of the Holo- cene, when the site was abandoned. At the beginning of the Holocene the territory of Western Georgia was characterized by a rather temperate climate; co- niferous species of trees, including fir, spruce, and pine, were widespread. The inhabitants of the site, the- refore, had chosen a strategical- ly convenient place for settle- ment, only 15km from the sea coast, on the banks of a river flowing into the Black Sea, on the boundary of two landscape zones – the valley and the foot- hills. Stratigraphy of the site During the excavations Gogitid- ze paid little attention to strati- graphy. He pointed out that the discoveries were related to the bottom of the humus layer on top of a brown loam layer at the depth of 0.5–1.0m. Gogitid- ze’s descriptions indicated that the site is not stratified. How- ever, in 2019, in the central part of the cape, we managed to find an area with clearly defined stratigraphy. We were able to lan Çemi (Rosenberg 1994) in North-East Anatolia and indicates the movement of Trialetian Early Holo- cene inhabitants from Anatolia to the South Cauca- sus. Excavations of the Kobuleti site have determined that this case was not the only one, since the mate- rials from Kobuleti reflect an undoubted connection with the migration of the Early M’lefaatien popula- tion, which was also still in the Pre-pottery phase of development. The site became known in 1960 as a result of re- search by Nino Berdzenishvili and Lamara. Nebierid- ze (Berdzenishvili, Nebieridze 1964). However, ex- cavations were only undertaken many years later, between 1971–1986. These were carried out by Ser- go Gogitidze, who uncovered about 600m2 of the site (Gogitidze 2008). The result was a collection of stone artefacts (more than 30 000), including about 2000 tools. The research results were published, but this publication left numerous questions unanswered. The author was unable to ascertain the cultural affiliation of the site, failed to establish the stratigraphy of the site, or to determine the connection between the in- depth artefacts and materials of the Stone Age. Materials from this site have been associated with the Early Neolithic in Georgian historiography, al- though there are no reasons for this. Fig. 1. Early Holocene sites with bullet-shaped cores and with microbla- des with abrupt retouch. Map of sites location. Guram Chkhatarashvili, Valery Manko 30 make a trench in an area with a con- centration of basalt stones, which had created a kind of stratigraphic trap for deposits. As a result, we were able to distinguish layers of loams of various shades of brown under a layer of humus. We re- corded the following stratigraphy in the central part of the excavation site: ❶ 0–0.2m: a layer of black humus with sand; ❷ 0.2–0.3m: a layer of dark brown loam with an admixture of humus; ❸ 0.3–0.45m: a layer of brown loam; ❹ 0.45–0.65m: a layer of light brown loam with a large amount of basalt gravel; ❺ Below 0.65m: a layer of yellow loam. The cultural layer was found in the brown loam la- yer, while the yellow loam layer was absolutely ste- rile. The stratigraphic layer 2 had been the most af- fected by various kinds of destruction, including flushing and using the land for agriculture. Never- theless, the lower boundary of the layer was deter- mined very clearly. The layer contained many basalt stones, and its lower boundary made it possible to clearly separate complexes of different time periods. The same method enabled us to separate the strati- graphic layers 3 and 4. Thus layers 2–4 are cultural layers of different time periods. The cultural layers have been assigned the following numeration: 0 (layer 2), 1 (layer 3) and 2 (layer 4). In the process of the excavations we disco- vered 12 pits with diameters of 0.7–0.9m and depth of up to 0.5m. Pit 5 is connected to layer 0, pit 6 to layer 1, and pits 1–4, 7–12 were connected to cultu- ral layer 2 (Figs. 3, 4). Therefore, we can see that the site had existed for a very long period of time, enough for the deposition of a layer of brown loams with a depth of up to 0.45m. The chipped stone industry We will summarize the information about the stone industry from the site. A total of 1533 artefacts have been discovered, 938 made of flint and 595 made of obsidian (see Table 1). The technique of blank removal is used to obtain blades and microblades by the method of manual pressing. Out of the 625 blade blanks and their seg- ments, only 25 are associated with blades. We have discovered 194 bladelets and 139 microblades. The absolute majority of bladelets and microblades have a width of 0.5–1.2cm. To obtain such bladelets and microblades, bullet shaped cores were used (Fig. 5.1). The discoveries of round tablets are also asso- ciated with the same cores (Fig. 5.2), with the nega- tives from removing flakes to correct the working platform. In general, we can say that flint flaking occurred mainly outside the site. This theory is supported by the evidence of the ratio of blades and flakes. There are more blades presented than flakes. This fact in- dicates that most of the artefacts were brought to the site already ready. Only a small number of bla- delets and microblades were produced on the terri- tory of the site (it is important to note that the pro- portions of blades and flakes on our excavation area are similar to the proportions found by Gogitidze). This conclusion is supported by having discovered only an extremely small number of flakes, chips and chunks. They are also smaller than the blades. This suggests that the site was visited periodically, and that the base camp of the visitors was in a different place. There are 262 tools in the complex, 105 of them made of flint and 157 made of obsidian. The most numerous are the retouched blades, bladelets and microblades, as well as their segments (89). Most such artefacts have a small semi-steep retouch along the edge (Fig. 5.28,31), but there are some with alter- native retouching (Fig. 5.22). There are a lot of bla- des with notches (27). There also are marked arte- facts with single wide notches (Fig. 5.25) and arte- Fig. 2. Kobuleti: general view from the south. Kobuleti site> the evidence of Early Holocene occupation in Western Georgia 31 facts with 2–3 edge notches (Fig. 5.26–27,29–30, 33–35). The burins are presented in a large series (62), and are characterized by great typological diversity. There are some burins on truncated facetted blades (Fig. 5.11,13–15), including bilateral burins (Fig. 5.14). There are many angle burins on broken blades (Fig. 5.12,16,19,24), such burins are often double (Fig. 5. 12,16). There also is a symmetrical dihedral burin (Fig. 5.23). All of the listed burins are made on bla- des. All the transverse (Fig.5.22) and dihedral angle burins (Fig.5.17–21) are made on flakes. There is one combined tool: a burin on a truncated facetted blade-endscraper. There are very few scrapers (15) in comparison to burins. All of them are made on flakes and are end- scrapers (Fig. 5.3–7). There is a series of chisels (15) made on massive segments of blades (Fig. 5.9–10). Some of the retouched flakes were probably used as scrapers and chisels (9). Truncated blades were also found (19), including blades with oblique truncation (Fig. 5.8.37) and a negative of a microburin spall on a blade with ob- lique truncation (Fig. 5.36). We can observe quite a representative complex as- sociated with hunting tools. This is a series of blade- lets and microblades (25) with abrupt retouch. These artefacts fall into two groups according to the width of the working blank. These are microblades and bla- delets with a thickness of about 1mm (Fig. 5.38, 40,42–47, 51–54,57–58), and massive microblades and bladelets with a thickness of up to 3mm (Fig. 5.39,41,48–50,55–56). We have concluded, based on the results of a use- wear analysis, that these artefacts are associated with hunting tools. We don’t see any traces on the edges of these tools that would indicate intensively using them as knives. On the other hand, we observe the traces on the retouching surfaces of these tools, indicating that they were inserted into the bone ar- tefacts. In our opinion, the backed bladelets and mi- croblades with abrupt retouch were made to be in- serted into bone points. We know of discoveries of such points in Early Holocene complexes of the South Caucasus. For example, such a point was found in the Early Holocene complex of Kvachara (Bader, Tsereteli 1989.Fig. 62.20). The use-wear analysis of flint and obsidian artefacts was carried out in the laboratory of Traceological Department at Georgian National Museum. The arte- facts were studied in two stages. The first was the microscopic study of the surface of the sample. Dif- ferent types of completely natural traces are left on the surface (lines, scratches, polishes, blunts, etc.) of the tools after usage (Semenov 1957; Semenov, Korobkova 1983), for the study of which binocular (MBS-9) and metallographic (Olympus) microscopes were used. The second stage of the research con- cerns the functional analysis of artefacts, which re- sults in the classification (Korobkova 1987; Esaki- ya 2005) of tools, on the basis of which the econo- my, its leading and secondary industries, site func- tions, economic characteristics and so forth are re- vealed. In general, the typology of the complex indicates that the site was used as a temporary hunting logistic camp, and very few production activities were car- ried out here. Fig. 3. Kobuleti: pit 7.

Kobuleti site> the evidence of Early Holocene occupation in Western Georgia 33 Cultural affiliation of the site The question of the origin of the Kobuleti industry cannot be solved as it is based only on the local ma- terials. At the end of the Pleistocene, there was sim- ply no single industry on the territory of South Cau- casus that could have had a connection with the Ko- buleti complex. When we compare the M’lefaat industry with the Ko- buleti complex, we must refer to the materials of the earliest M’lefaatien sites. This is because the appea- rance of the Kobuleti industry was not accompanied by starting cattle breeding and agriculture. Mean- while, traces of cattle breeding in the M’lefaat com- plexes can be traced back to the 9th millennium BC (Zeder 2008). Therefore, only migrants during the very beginning of the Holocene could have brought the traditions of a hunting society. Because of this, it is essential for us to compare the materials of Ko- buleti with the complexes of M’lefaat (Dittermore 1983), Karim Shahir (Howe 1983), and the lower la- yers of Chaga Sefid (Hole 1977). We can see a deve- loped pressure technique in the materials of these sites. Based on the use of conical and bullet-shaped cores, we observe a combination of types of trun- cated blades and bladelets with abrupt-retouched edges. Other types of tools (burins, scrapers, notch tools) are also common within the Kobuleti industry. It is worth noting that the burins with bila- teral forms are similar in both cultures. In addition, the Early M’lefaatian sites are undoubtedly older than Kobuleti, since almost all of the listed sites are dated as the Final Pleistocene. At the mo- ment, we have only one absolute date for Kobuleti (layer 2, pit 7): 8670±100 uncal BP (SPb-3084). Thus, the industry of Kobuleti and the early M’lefaat have many simi- larities, so we can presume there was a migration of some of the M’lefaatian population to the ter- ritory of the South Caucasus. This migration was the first step in the spread of the pressing flak- ing techniques in South Caucasus and the South of Eastern Europe (Crimea, the Steppe zone of Ukra- ine and Moldova), where the Kuk- rek Culture with the same characteristics of the co- nical cores and tools developed from the first half of the Preboreal (Manko 2013; 2015). At the same time, we must understand that M’lefa- atian migration did not lead to the spread of animal domestication in the region, since at the beginning of the Holocene carriers of the M’lefaatian industry also did not practice reproductive economy methods (Zeder 2008). Possible M’lefaat migration to the Caucasus The theoretical basis for the search for arguments about the possibility of migration and its starting and ending points was the theory of Lev S. Klein (1999) about the archaeological criteria of migra- tions. Klein gives the basic criteria of migration in archaeology as legality (complex similarity of two complexes of cultures of the initial and final point of migration), unpreparedness (spontaneity, abrupt change of cultures) and a contact in time and space. He believes that the simultaneous application of all the criteria is excessive, because it can only happen in an ideal situation, when the archaeologist has a comprehensive source base. However, when ana- lysing the migration of the M’lefaatian population to the territory of Western Georgia, we can apply all Type Flint % Obsidian % Total % cores 2 0.21 1 0.17 3 0.20 tablets 3 0.32 1 0.17 4 0.26 blades 17 1.81 8 1.34 25 1.63 bladelets 110 11.73 84 14.12 194 12.65 microblades 83 8.85 76 12.77 159 10.37 flakes 180 19.19 92 15.46 272 17.74 primary flakes 5 0.53 1 0.17 6 0.39 chunks 156 16.63 65 10.92 221 14.42 chips 271 28.89 107 17.98 378 24.66 burin spalls 6 0.64 3 0.50 9 0.59 tools 105 11.19 157 26.39 262 17.09 burins 32 30.48 30 19.11 62 23.66 scrapers 6 5.71 9 5.73 15 5.73 burin-endscraper 1 0.95 0 0.00 1 0.38 chisels 9 8.57 6 3.82 15 5.73 retouched flakes 5 4.76 4 2.55 9 3.44 retouched blades, 30 28.57 59 37.58 89 33.97 bladelets, microblades notched blades, 10 9.52 17 10.83 27 10.31 bladelets, microblades truncated blades, 7 6.67 12 7.64 19 7.25 bladelets, microblades microblades with 5 4.76 20 12.74 25 9.54 abrupt retouch total 938 100\61.19 595 100\38.81 1533 100 Tab. 1. Kobuleti: typology of flint and obsidian artefacts. Guram Chkhatarashvili, Valery Manko 34 three criteria. Of course, we cannot consider the ap- plication of all the criteria excessive, because we only have stone tools for analysis. We estimate the similarity of Kobuleti with M’lefaat complexes as almost complete. We find the follow- ing types of artefacts that are common: ❶ Conical cores for obtaining bladelets and micro- blades with the use of the pressing technique; ❷ Bladelets and microblades with abrupt retouch; truncated facetted bladelets; ❸ Blades with flat ventral retouch; ❹ Bilateral burins on truncated facetted blades; ❺ Occasional use of the microburin technique in the process of truncating faceting. The criterion of spontaneity is also almost ideal. In the territory of Western Georgia, the emergence of the Kobuleti industry comes as a surprise. The cul- ture appears in fully completed form at the begin- ning of the Holocene. The previous development of the archaeological cultures of Western Georgia does not allow us to study the participation of some groups of the indigenous population in the genesis of the Kobuleti industry. The development of the pressing technique was an innovative feature that was not characteristic of any of the previous archa- eological cultures of the Caucasus. Absolutely innovative were the forms of cores and hunting weapons. The only archaeological culture that could theoretically act as a precursor to the Ko- buleti industry was the Epigravettian, which disap- peared in the Western Caucasus before the advent of the Kobuleti industry. Even if we assume that some part of the Epigravettian population was in- volved in the formation of the Kobuleti industry, the huge number of innovative features cannot explain it. Moreover, one of the latest sites of the Caucasus, the Kasoghsky Cave, has no signs of using pressing flaking technologies to obtain blades (Golovanova, Doronichev 2012). Thus, the spontaneity of the emergence of the Kobuleti industry in Georgia is un- questionable. The criterion of contact in time and space can also be traced. The available absolute dates convincing- ly show that the M’lefaat industry appeared earlier than the Kobuleti industry, but also coexisted with it. Such chronological evidence indicates that the migration vector could be directed only from the ter- ritory of Iran and Iraq to the territory of Georgia. Mapping of the oldest complexes of all three indu- stries clearly shows the route of the movement of mi- grants, on which there were no significant obstacles. Thus, we have all the theoretical prerequisites to draw conclusions about the possibility of global mi- gration of the M’lefaatian population in the Cauca- sus. Conclusions The migration of the M’lefaat population led to the spread of the pressing technique, first to the territo- ry of Western Georgia, and then to the territory of Ukraine and Moldova (the so-called Kukrek Culture). Later, the carriers of this technology became the founders of the Neolithic culture on the territory of the South Caucasus and the south of Eastern Europe. In Georgia, the sites of Anaseuli 1 and 2, Gurianta (Nebieridze 1972), Darkveti layer 6 (Korobkova 1996) appeared when the Kobuleti traditions were developing on the Neolithic stage. On the territory of Ukraine, Neolithic Sursk and Donetsk cultures appeared on the basis of the Kukrek culture.
