The paper presents new data on foraminiferal assemblages and stratigraphy of the southeast Western Siberia (the Tomsk Region), supporting the Santonian – Early Campanian age of the Slavgorodskaya Formation of the horizon bearing the same name. The lithology and microfauna of the Slavgorodskaya Formation were characterized within the new section ZN-4 in the southeastern district, as given in Table 1. Table 2 demonstrates the correlation of the Santonian – Lower Campanian foraminiferal zones and beds of the central and south-eastern districts of Western Siberia.
