New research of Rostovka site near Omsk

The paper contains an information for new investigation Rostovka site, located on the left bank of the Om River in proximity of Omsk and now actually in the city of Omsk. For continuing excavation, we chose the small, vacancy area to the south from excavation area of V.I. Matyuschenko. In the course of study we found the burial of an adult, stone artifacts and ceramic fragments, which undoubtedly had a direct bearing on complex, studied by V.I. Matyuschenko. Lithic assemblage consist of a several arrowheads, stone knife, fragments of knife-shaped blades, tool blanks. Most of them are made of a single lithic raw material and, undoubtedly, compose a single group. We find the absolute analogies in the burials of Krotovo culture at the Sopka 2/4 Б, В. Ceramic complex consists of two groups of ware. The first includes fragments, directly related to the Seiminsko-Turbino complex. This pottery can be a sort of synthesis of ornamental traditions, bundling the features of Krotovo and Petrovo archaeological cultures, and probably associated with process when of representatives of North-Kazakhstan group of Petrovo culture penetrated into the territory from the south-west. We also obtained the second pottery complex, which was dated by V.I. Matyschenko and G. V. Sinitsyna to later period of 8th - 6th centuries BC. Unfortunately, we can not confidently confirm or refute this chronological determination, as well as detect its cultural attribution at the moment. Thus, we propose to consider this ceramic complex as some specific cultural constitution, and it is off to prove its cultural and chronological position.
