Neolithic Complex of the Settlement of Barsova Gora II/9

Purpose. Materials published here describe findings on the ancient settlement Barsova Gora II/9b (located 7 km to the west of Surgut city on the right bank of the Ob river). Over the 5 years of excavations, the remains of structures from different time periods were uncovered and studied, among which 5 seated below grade square and rectangular dwellings stand out.
Results. Original flat-bottomed pottery, clay ornamented bars and a spherical pommel have been found inside these dwellings. Clay bars were probably used as spatulas for smoothing dishes, skin scrapers. Among stone tools, polished ones predominate: chopping tools (axes, adzes, chisels, including grooved ones), lancet-shaped arrowheads and knives, as well as abrasives. Flint tool findings were less common: a few leaf-shaped arrowheads, scrapers and one lithic core. A fragment of a quartz lithic core and about ten quartz flakes were found as well. Among the pottery next to flat-bottomed vessels, there are round-bottomed vessels. Generally pottery is decorated in a variety of ways – drawn, impaled, using a walking comb stamp, with pits. Among the patterns there appears straight, broken or wavy lines, areas of a walking stamp. Clear geometric shapes are rare. On some pots horizontal compositions are replaced by vertical ones in the lower half of the vessels. Flat bottoms are ornamented with crossed, wavy and other patterns.
Conclusion. Incorrect functional identification of the clay bars during first excavations led to initial incorrect dating of the settlement as belonging to the Early Bronze Age. The stratigraphy and radiocarbon dating during the new excavations revealed earlier settlement dates going back to early Neolithic. Some similarities to these structures and settlement type can be found in the ancient settlements of Boborykino and Bystrinsky cultures, Petrovoborsky and Kayukovsky types, settlements of Amnya I and others within the Eneolithic Period as well. However, the settlement of Barsova Gora II/9b is a unique cultural type dating from 6th – early 5th millennium BC.
