... sum, the preferable blanks for pre-cores were the plate-like primary flakes, natural flakes, and plaquettes ( fig. 5: 3). These led to the appearance of the narrow flaking surface pieces, which prevail over the pre-cores with the sub-cylindri The remainders of pre-cores were made on roundish elongated nodules close to the cylindrical shape. The former aimed the bladelet / micro-blade production, while the latter is supposed to be the blanks for blade ...

... equal numbers represent the unidirectional and bidirectional cores for blades: 21 and 27 pieces, respectively (table 3; fig. 5: 4). The bidirectional blade cores show the clear difference between striking platforms: the main striking platform is arranged at the nearly right angle to the flaking surface, while the opposite supplementary platform is arranged at a very sharp angle toward the flaking surface ( fig. 1 с татті ( fig. 1: 5).

About half of the bidirectional cores are represented by two adjacent or alternative flaking surfaces ( fig. 1: 2, 5). The «real» bidirectional cores with alternating negatives on a single flaking surface are known, as well ( fig. 2: 2, 3).

Most blade cores were made on rounded nodules ( fig. 1: 4). Also, the plaquettes, natural flakes, and flakes were used as blanks for blade cores production (table 3; fig. 5: 6). The metric ranges of blade cores are the following: length -from 47.16 to 91.80 mm; width -from 24.76 to 69.25 mm; thicknessfrom 17.28 to 83.43 mm. The mean blade cores dimensions are the following: length -65.37 mm; width -39.44 mm; thickness -40.19 mm. The unidirectional types (26 items) are the most numerous blade / bladelet ...

... width -39.44 mm; thickness -40.19 mm. The unidirectional types (26 items) are the most numerous blade / bladelet cores, followed by bidirectional (15 items), and multi-platform (4 items) types (table 3; fig. 1 fig. 1: 3). A combination of adjacent narrow and flattened / sub-cylindrical flaking surfaces and cubic types are not numerous (table 3; fig. 5: 8). More than half of blade / bladelet cores were made on natural flakes ( fig. 3: 2; 4: 2, 4; 5: 9). The rounded nodules were used for sub-, cylindrical unidirectional, and bidirectional blade / bladelet cores. The narrow flaking surface blade / bladelet cores were produced on plate-shaped raw material. The values of blade / bladelet ...

... narrow flaking surface types dominate the bladelet / micro-blade cores assemblage (table 3; fig. 3: 3; 4: 1, 3; 5: 11). Both unidirectional and bidirectional bladelet / micro-blade cores are important ( fig. 5: 10). The plate-shaped pieces are the main types of raw material blanks for bladelet / microblade cores production (table 3; fig. 3: 3; 4: 1, 3; 5: 12). Some of the narrow flaking surface bladelet / micro-blade cores demonstrate the wedge-shaped working surfaces ( fig. 3: 3; 4: 3). Along with the bladelet / micro-blade cores with pyramidal ...

More than half of «regular» flakes show differently incurve lateral profiles ( fig. 7: 5). About two-thirds of «regular» flakes exhibit the feathering distal extremities ( fig. 7: 9). The sum of multiple and trapezoidal cross-sections amount the half of the assemblage ( fig. 7: 13). The unidirectional scars dominate the types of dorsal patterns ( fig. 8: 1).

The primary pieces compose 10.41 % of «regular» flakes. The totality of items with cortex on the dorsal surface reaches up to 55 % of «regular» flakes ( fig. 8: 5). The flakes' striking platforms are mainly plain, without overhang trimming, and not abraded ( fig. 8: 9, 13). The dominating right-angled (73.15 %) and un-lipped (88.25 %) butts correspond with pronounced bulbs (79.21 %). Latter is supposed to be the indication of direct hard hammer percussion (Pelegrin 2000, p. 75-76). The «regular» ...

... than differences. On the other hand, the lamellar débitage is distinct from the «regular» flake assemblage by the number of attributes. Due to the increasing portion of shapes, such as crescent, leaf, rectangular, and triangular, the lamellar blanks look geometrically more regular ( fig. 7: 2-4). Moreover, about half of them were detached on-axis 5; fig. 6). The elongation indexes for blades, bladelets, and micro-blades compose 2.58, 2.79, and 3.32, accordingly. That is, the «reg-ular» lamellar blanks are both not very long and not very elongated. At the same time, the lamellar pieces are relatively thick; the width-to-thickness ratios for blades, bladelets, and micro-blades compose ...

... débordante blanks are the detachments from the lateral sides of cores. The main attribute of the débordante pieces is the lateral steep crosssection ( fig. 9: 3-5, 7-9, 14). The «steep» side of the débordante piece is arranged at a nearly right angle to the ventral surface (Boëda, Geneste, Meignen 1990). These pieces are also known as «corner» blanks ). The main technological reason for débordante detachment consists in the creation of the needed transversal convexity of the core flaking surface. ...
