Abstract
The genera Staffellaeformes and Depratina are widespread in Lower and Middle Pennsylvanian rocks of Eurasia and are important for Pennsylvanian biostratigraphy. The lineage Staffellaeformes-Depratina represents one of several major trends in the fusulinid evolution recorded in the Bashkirian-Moscovian. The genus Depratina first appeared in the late Bashkirian but continued and thrived in the Moscovian. In the Southern Urals, Depratina prisca first appeared close to the base of the Moscovian, and can be used as a marker for this boundary.
