Popis:	It is analyzed the evolution and biostratigraphic role of species Verella, Eofusulina, Paraeofusulina and Postverella from subfamily Eofusulininae in Upper Bashkirien and Lower Moskovien sediments of Middle Carboniferous in the Urals. Verella species characterizes the Upper bashkirien, the beginning of the Moscovien stage is fixed by major spindly fusiform Eofusulina triangula and E. triangula rasdorica, which along with zonal types of Aljutovella aljutovica and Depratina prisca reference points of the boundaries of the Bashkirien and Moscovien stages and can be recommended as a marker taxa of the Middle Carboniferous stages.
