Faunal lists always include deer and bear, and often— wild goat including Capra caucasica as well as wild boar, besides carnivores, small mammals, birds, etc. The Mesolithic of Georgia was sub-divided into several regional variants: The cited study, based mostly on the analysis of the assemblages originating from the Black Sea littoral, suggested a tripartite chronological subdivision of the Georgian Mesolithic.

It should be noted that this subdivision was not supported by radiocarbon data, and is based mostly on typological characteristics of the assemblages, with very limited stratigraphic evidence about their relative chronologic relationships. Characteristic tool types include backed bladelets, backed points microgravettesshort asymmetric triangles, and lunates.

In the middle stage the points disappear. The microliths are dominated by lunates, trapezes make their fi rst appearance and triangles become rare. In the late stage the same trend continues: The Trialetian cultural entity14 was defi ned on the basis of two assemblages from the rock-shelters Zurtaketi and Edzani in the Southern Georgia. The industry is characterized by abun- 3 6. An attempt of N. Tsereteli15 to apply the chronological scheme of the Black Sea littoral to the whole Georgian Mesolithic can be hardly regarded as successful.

At any rate, this proposed scheme, as well as chronological correlations between the assemblages from different parts of Georgia should be further tested and explored.

Thus we begin our explorations by testing the site of Kotias Klde, visited in the past by D. Tushabramishvili16 which had produced the desired Mesolithic-Neolithic sequence. This sequence seems to begin at the end of the Upper Palaeolithic sequence recognized in our previous excavation project at Dzudzuana cave. The entrance area of the cave resembles a rockshelter Klde is rock in Georgian. From there the cave extends as a long, not fully explored corridor which splits into diverging karstic cavities which were not mapped as yet.

The following preliminary report summarizes the results of the excavation of the Mesolithic layer B at Kotias Klde during the seasons, the excavated area consisting of 15 m2. The Neolithic remains will be published separately in due course.

The squares in the entire excavation were dug to varying depths of ca cm without reaching bedrock. The digging is done in sub-squares of 0. All excavated units were wet-sieved in a 2 mm mesh. The exposed stratigraphy is as follows: A stony layer, varying in depth from 30 to 50 cm, comprising an accumulation of rocks of different sizes which fell from the ceiling, a result of the cave walls deterioration due to weathering. Though there are a few pottery shards of the Bronze Age and later periods, most of the material at the base of the layer is local Neolithic.

This is a shallow pit-house, some 30 cm deep which was dug into layer B. It contained the distinct lithic 4 7. A similar industry was reported from other Neolithic sites in the region such as the Darkveti Rockshelter, ca km away in the Kvirila River gorge, 19 or the site of Paluri which is situated further away, on the Enguri River, also in Western Georgia.

Stones crushing the skull, the knees and lower limbs of the skeleton were placed at the time of the burial.

Two superimposed short-term hearths were exposed some 20 cm above the skeleton as if sealing the grave. Clay to loam deposit, interspersed with limestone fragments, which we have subdivided into B1, B2 and B3.

All sub-layers contain a Mesolithic industry to be 5 9. B1 is a grayish clay deposit with numerous small limestone fragments of unknown depth as well as animal bones and artefacts. B2 is a deposit incorporating a stone pavement while B3 is a ca 30 cm thick deposit of grey clay incorporating small limestone fragments. All units indicate the presence of human occupations, rich in material remains.

Four radiocarbon readings from this layer indicate a range from 12, cal. Exposed to a very limited extent, it consists of yellow, compact clay-come-loam sediment.

Preliminary studies reveal that it contains a late Upper Palaeolithic industry, though more exact defi nition awaits further research. Dates are given in year BP. All four derive from the same square I 10 but from different depths. Each depth was dated by one bone and one charcoal samples. The concentration of radiocarbon in the samples was determined using the Accelerator Mass Spectrometry technique. All samples were prepared at the Radiocarbon Laboratory of the Weizmann Institute using the procedure presented in M.

The bone samples were pre-treated in order to extract the collagen fraction. A very low collagen content as for RTT is an indication of bad bone preservation.

To ensure radiocarbon date accuracy in such a case, collagen from sample RTT was analyzed by Fourier Transform Infrared analysis to check its quality.

The spectrum obtained indicated pure collagen according to the criteria in Yizhaq et al. In both cases the charcoal has been dated younger than the bone by years. This could indicate systematic intrusion of charcoal from later layers, but more data should be collected in order to confi rm this option. The lithic industry The detailed analysis of layer B lithic industry did not reveal a techno-typological subdivision matching the stratigraphic one described above.

During the lithic study we took into account only the material from clear stratigraphic contexts, discarding that derived from units where the stratigraphic division was problematic or obvious admixture occurred. Therefore, for the purpose of this report and in order to have a reasonable sample 6 The fi rst two are obtainable on the plateau within a few kilometres from the cave, while the closest obsidian sources are some 80 km away.

The available core types include the following: The classifi cation of the cores demonstrates several types of state of discard.

The core types and the scar patterns on debitage items both blades and fl akes and the retouched pieces fi g. The large number of amorphous cores and the evidence for rotation of the striking platforms as well as the presence of three striking platforms refl ect the pressing need for more blanks in a situation when raw material was relatively scarce or that obtaining additional nodules was not feasible for various reasons.

We also observed the presence of one hammerstone. The large number of chips small debris does refl ect the reshaping of tools on site. In addition, numerous pieces show signs of burning and heavy re-use. The main tool groups are varieties of backed and retouched bladelets including the obliquely truncated types However, the distinctive tool types of this Mesolithic industry are the scalene and isosceles triangles, shaped mostly by bi-polar retouch from blades and bladelets.

In several cases the truncation on the shorter plane is done on the proximal part of the item fi g.

A few items among the obliquely truncated bladelets resemble in their overall shape the triangles. We classifi ed the latter as triangles when the two long edges were straight and converging to a point. Other categories are not much different from those observed in assemblages of the late Upper Palaeolithic of the region25 and see for example the truncations, fi g. Perhaps it is the common local tradition that the endscrapers Among them is a handle made of a red deer antler with a hole for fi tting in a tool, and several point tips.

The fauna These are preliminary results of the ongoing taphonomic and zooarchaeological analysis of the faunal remains from layer B excavation seasons. The complete zooarchaeological and taphonomic coding and analysis procedures used to collect and present the data are detailed in G. Each specimen, identifi ed or not, was examined and scanned for preliminary taphonomic observations.

Identifi ed elements were coded in an electronic database both anatomically and taxonomically if possible.

As with potteryinnovation in projectile point styles was quite limited at any particular time. Toolmaking skills were passed down from father to son, who worked hard to adhere to the proper pattern. Toolmaking changed gradually over hundreds of years, and no one likely saw any change in stone-tool technology during his or her lifetime. For every fully formed PPK, probably dozens of other stone tools and hundreds or perhaps thousands of pieces of unused stone debris were littered in human habitations all over Georgia.

These are generally not as identifiable to specific time periods by archaeologists, but they are studied in detail because they exist in such quantities; they can reveal information about past Indian societies. Flint Projectile Points Georgia is a geologically diverse state, and the stones used by regional Indians reflects that diversity.

Southern Georgia is rich in chert, a brownish colored flint. Chert was often treated with heat, which made it much easier to flake and also turned its color to shades of red.

Northwestern Georgia has high-quality chert of a gray to black color, while the Piedmont and Blue Ridge areas are rich in crystal and milky quartz. While not as easily worked as chert, quartz was used in great quantities by Indians in those areas. Exchange of stone across the different areas of the state was very common during some periods.
