This paper represents results of the complex research of the Senomanian deposits from right-bank of the Volga region. It is suggested to revise the stratigraphic position and the range of previously established Melovatka suite (1999) (Senomanian stage). It has been revealed that major part of the middle (silt-argillaceous packet) subsuite and the upper (sandy packet) sub-suite are missing from the stratotype section, but determined by the author within the Senomanian stage of the right-bank Volga region.
