Popis:	Two spore-pollen spectra from the stratotype of the Upper Kazanian Substage and the reference section of the Urzhumian Regional Stage in Cheremushka Ravine are studied. In composition both spectra closely resemble the palynological assemblage that was previously known from the Upper Kazanian Substage and the upper part of the Lower Kazanian, but they differ (have a more ancient “appearance”) from the Urzhumian spectra known from the Sukhona River. Thus, the sample studied from Cheremushka Ravine apparently occupies a lower stratigraphic position than the most ancient localities of spores and pollen on the Sukhona River (Bobrovskoe and Vostroe).
