The boundary between the Lower and Middle Carboniferous section was identified by a maximum regression and biostratigraphically by the appearance of Declinognathodus genus conodonts. The assemble of typical association for Middle Carboniferous conodonts (Declinognathodus noduliferus, D. lateralis and D. inaequalis) together with typical for Early Carboniferous foraminifera (Rectoendothyra donbassica, Endothyranopsis umbonatus, Janischewskina sp., Eostaffell amirifica and Eostaffellina actuosa subsymmetrica, E. monstruosa al.) are in close vicinity of the biostratigraphic boundary.

Keywords: Lower Carboniferous, Middle Carboniferous, stratigraphically boundary, foraminifera, conodonts, Timan-Pechora petroleum province.
