[2] The culture is noted for its ceramic vessels with tipped or beet-shaped bottom, thin-walled and thoroughly dressed, later supplanted by more thick-walled round- and flattened-bottom.
Vessel ornamentation is dominated by jagged and smooth lines, and comb pattern, sometimes with grid, triangle, and zig-zag decorations.
In rare cases, vessels have print-comb ornamentation, more typical to the Chalcolithic art of the Eastern Urals and Tumen-Ob region.
[4][5] However, the archaeological detection in southern Western Siberia of the Neolithic population south-western connections with Bolshemys and Kelteminar cultures is not corroborated by anthropological studies as a migration impulse, and can be explained by the existence in a distant past of common anthropological genetic substrate of the population, which probably preserved intercultural contacts between the offspring cultures.
In the Early Bronze Age (3200–2300 BC), the population of the Baraba steppe retained capacity of the indigenous anthropological substrate, having assimilated the migrant Bolshemys Culture.
