main mass of stone artifacts is made of flint slates
(1,089) and flint (790). There are also discovered
few specimens of items made of sandstone,
quartzite and basalt.
Primary refining. Tools of Layer VI are made
of big flakes, with very big, massive chips. Among
chips, there are several specimens (2.25% of total
number) whose length exceeds 9 centimeters.
However, the biggest percent of flakes (some 70%)
is 3 to 6 centimeters long, 2.5 to 4 centimeters wide
(54%) and 1 to 2 centimeters thick (67%).
River pebbles in the collection of Layer VI
consist of 37 specimens, including some refined in
the notched form. All they are big, spherical.
Cores. There is identified a total of 9 speci-
mens, including 4 flint cores, 3 flint slate cores and
2 basalt cores. All they have the form of a rem-
nant of nucleus. Typologically, the cores are sub-
divided into the following three types: single-plat-
form ones (2) (Fig. 43, 3), discus-form-unilateral
ones (5) and discus-form-bilateral ones (2) (Fig.
43, 1, 2).
Core breaks (17) can hardly be specified.
Series, the exact expression of initial form and full
traces of chip negatives are absent. It is to con-
clude from the nature of negatives that some of
the breaks initially served as nucleuses of a certain
form. Among them, there are discovered two fab-
ricators with well detectable traces in the form of
small star.
Typological description of stone tools is as
follows. In Layer VI, there was discovered a total
of 427 stone tools, including (as the initial appear-
ance of) numerous tools made not of whole peb-
bles but specially chopped flakes. Here, there are
classical choppers, chopping tools, bifaces,
cleavers, pointers, limaces, racloirs, scrapers,
picks, knives, notched tools, and denticulate and
fragmented kinds of tools.
More primitive prototypes of the aforesaid
kinds of tools are discovered in the Cave's Lower
Layers VII – X.
Choppers (14 specimens) (Fig. 42, 1, 5; 44, 3,
4; 45, 2) are made largely of rounded pebbles.
They are subdivided into the following three
groups: large-size ones (3 specimens), middle-size
ones (9) and small-size ones (4). Their working
blades are sharper and harder. The basalt parts
are very easy to be covered by hand.
Chopping tools (5 specimens) (Fig. 42, 2; 44,
1, 2) are made largely of river pebbles bound from
both sides. Dimensions of a chopper and a chop-
ping tool are largely 17/10/17 centimeters, with the
average size of 12.5/7/2.5 centimeters and the
smallest size of 6/4.5/2.5 centimeters.
Handaxes (8 specimens) were made largely of
felsites and similar river pebbles. Types of the
handaxes are as follows: elongated-oval ones (3)
(Fig. 45, 1), fully refined almond-shaped pones (2)
(Fig. 46, 2), a lancet one (1), a rounded-oval one
(1) (Fig. 46, 1), and a nucleus one (1). The handax-
es have the following dimensions: 11.4/7.5/3.8 cen-
timeters, 13.5/10.5/4.5 centimeters, and 18/10/7
centimeters.
Discus-like tools (3 specimens) are refined
from both sides. The working blade is convex.
Cleavers (3 specimens) are made of basalt and
flint slate. One of them was split (yet in the ancient
time, perhaps when it was being refined) into two
slated parts, which were situated at different parts
of the site, as identified by the excavations.
In Layer VI, there are discovered a lot of
tools made of flakes only. In terms of being made,
they are subdivided into the following types:
pointers of different kinds, racloirs, denticulate-
notched tools, beak-like tools with ledges, chisel-
like tools, multi-blade (trapezium-like) conver-
gent tools, drills, borers, awls, knives, etc.
Pointers (7 specimens) are of the following
two categories: pointers with short, widened pro-
portions (3) and elongated pointers (4). Both cat-
egories vary strongly in terms of dimensions and
thus, can be subdivided into the following three
groups, depending on dimension and proportion:
small ones (3.5/2.7/0.9 centimeters), middle-size
ones (1.5/3.5/2 centimeters) and large-size ones
(6/4.1/2.2 centimeters). The majority of pointers
are middle-size ones. In some cases, the flaking
spreads over 2/3 of the tools' edges. There is no
two-sided flaking in the collection of pointers.
Owing to the blades being notched and the mas-
sive section, the pointers resemble ones of the
Tayacian type.
Limaces (6 specimens) are made of flint. They
can be subdivided into two groups: ones with no
thorough flaking of the edges (4) (Fig. 47, 2) and
