Abstract—
The Middle–Upper Oxfordian foraminifera were studied from the borehole section drilled in the east of the Moscow Region (Russia). The foraminiferal zones were distinguished in Oxfordian clays: Opthalmidium strumosum–Lenticulina brestica and Lenticulina russiensis–Epistomina uhligi. It was established that the distribution of foraminiferal assemblages varies throughout the Moscow Region.
