Exploration on the Kyzyl-su river
The Paleolithic detachment of the Shulba expedition of the Institute of History, Archeology and Ethnography of the Academy of Sciences of the Kazakh SSR conducted reconnaissance along the floodplain terraces of the Kyzylsu River (East Kazakhstan Region, Tavri District) from the mouth to the camp of the Arman sheep-breeding brigade. In the former village of Kyzyl-Kuigan, on the second terrace-like ledge, a massive flake of archaic appearance and a pebble-chopper with characteristic processing of the edge with large chips were found. Coarse-grained pear-shaped pebbles were used to make the tool. The dimensions of the gun are 13x9x4 cm. Several guns were found near the Koitas village on the right bank of the river, on the second floodplain terrace. They are slightly rounded and have a pebbly crust. Upstream of the Kyzylsu River, near Arman, in the cliff of the right bank, a chopper made of black-siliceous pebbles was found. Its dimensions are 8x6x3.5 cm. All items have a gall-like crust, are latinized and, undoubtedly, belong to the Old Stone Age.
Materials of a later time were found near Sotsgigiz on the second floodplain terrace on the right bank of the Kyzylsu River. Cores, arrowheads, scrapers, plates and production wastes were found here. The nuclei of prismatic spalling, amorphous and small in size. There are raw blanks of medium-sized cores. End scrapers on plates with an oval working edge predominate among the tools. Some have retouched sides. There are high-shaped scrapers, small arrowheads with double-sided leaf-shaped processing, plates with a blunt edge, microliths. The site can be attributed to the early Neolithic.
