The article considers the problem of dating and duration of the transition period from the Early Iron Age to the Late Iron Age on the basis of materials from the KozlovMys-2 burial ground in the Podtaezhny Pritobolye and monuments of the final stage of the Sargat culture. Based on a set of dates, a short - term chronology of transitional monuments of the forest-steppe and sub-taiga Trans-Urals is proposed-within the first half of the IV century AD. Keywords: Early Iron Age, early Middle Ages, Sargat, Kashin, Karym, Bakal cultures, chronology. Introduction The period indicated in the title in the archaeological record of the region under consideration is one of the least studied, especially against the background of fairly well-studied cultures of the Early Iron Age. We are faced with a whole set of problems of the Great Migration era that are waiting to be resolved. For example, when did the Early Iron Age cultures change to medieval ones? We are talking mainly about the disappearance of the Sargat culture, which occupied the entire forest-steppe, sub-taiga and partially steppe Tobol-Irtysh region for almost a millennium. Its upper limit was established as the III-IV centuries. not a very large set of facts: dating data from the burial grounds of Kalachevka [Mogilnikov, 1972, p. 68], Abatsky-3, and Sidorovka [Mogilnikov, 1992, p.297; Matveeva, 1994, p. 100; Matyushchenko and Tataurova, 1997, p. 82]. Radiocarbon dates were obtained for wood from the Tyutrinsky and Savinovsky burial grounds of the final stage in the interval of the N-W centuries. [Matveeva, 1993, p. 156, Table 52]. The joint occurrence of carved Sargat and Kashin ceramics and Yarsala and Tuman ceramics, ornamented with figured and combed stamps, at the Ipkul settlement allowed us to date it to the III-V centuries. [Koryakova, Morozov, Sukhanova, 1988, p. 126]. L. I. Pogodin determined the upper date of Sargat burials of the III-IV centuries by the main types of weapons [1991, p. 24]. A. A. Kovrigin, d ...
