pdf  Callovian and Oxfordian boundary in the Timan-Pechora province
The characteristic of the Callovian-Oxfordian sections deposits is given. The boundary between the Callovian and Oxford in the Timan-Pechora province, which is represented in the Jurassic period biogeographical ecotone, corresponds to the boundary zones of the international stratigraphic scale. It corresponds to the boundary between the terminal zone of the Callovian and the basement of the Oxfordian (zone). The sketch of paleogeography of Timan-Pechora province in the Callovian and Oxfordian is provided.

Keywords: Callovian, Oxfordian, stratigraphic break, ammonite zone, foraminiferal complex, Churkino Formation, Gorodetskaya Formation.
