Ustinova M.A. (2009) The distribution of calcareous nannofossils and foraminifers in the Callovian, Oxfordian, and Volgian deposits in the southwest of Moscow // Stratigraphy and Geological Correlation. Vol.17. No.2. P.204–217.
The distribution of calcareous nannofossils and foraminifers occurring in the Callovian–Oxfordian deposits in the southwest of Moscow is studied. Nannoplankton-bearing beds and foraminiferal zones are distinguished. The Retecapsa incompta Beds correspond in range to the Ophthalmidium sagittum–Epistomina volgensis and Ophthalmidium strumosum–Lenticulina brestica foraminiferal zones as well as the lower part of Epistomina uhligi–Lenticulina russiensis Zone. The Watznaueria manivitae, Crepidolithus perforate, and Watznaueria fossacincta (lowermost part) beds span interval of the Epistomina uhligi–Lenticulina russiensis Zone. The Watznaueria fossacincta Beds are concurrent to the Lenticulina ponderosa–Flabellamina lidiae Zone of the foraminiferal scale.
