Based on the results of paleomagnetic studies, which are part of intergrated bio-, chemo- and magnetostratigraphic studies of the Upper Cretaceous North Caucasus, analogs of magnetic chrons C34n and C33r are identified in the Podkumsky quarry section near the city of Essentuki. The Santonian–Campanian boundary is drawn in the section due to this, by analogy with the limitotype of the Campanian Stage at Bottaccione (Italy), and the early Campanian age of the deposits is substantiated, by analogy
