Paleopedocomplex was investigated in the Temizhbeksky section which is located in the natural outcrop of the Kuban river and has a thickness of about 50 m. Paleopecomplex was formed in the Eopleistocene, it consist’s of six paleosoil horizons lying in five lithological layers. Paleosoil horizons belong’s to four individual truncated paleosoil profiles. The upper profile lying in the single litho-layer and consist’s of one horizon which has vertic, stagnic and calcic features. Temporal and spatial relations of these features could be explained by three evolution stage of pedogenesis. The second profile lying in the single litho-layer and formed by two horizons of stagnic luvisol which also has vertic and calcic features referred to the younger upper paleosoil. The third profile transfixing two different litho-layers by cambic and calic horizons. Paleosoil also has weak vertic and stagnic features which could be explained by the soil self-development in a low-amplitude climate fluctuations. The lower profile lying in the single litho-layer and formed by the single calcic horizon with gleyic and vertic features. Pedogenesis could be explained by polygenetic model. Thus, investigated paleopedocomplex keeps information not less than twelve stages of litho- and pedogenesis. The term “polygenesis” has three different meanings in this case. The first – the pedocomplex polygenesis which is in a complex sequence of lithological layers and soil horizons. The second is in evolution of the individual paleosoil profiles in the pedocomplex which reflect a climate change. And the third is in inheritance of buried soil horizon by later pedogenesis.
