The paper represents an analysis of the vertical range of foraminifera in the Albian-Senomanian-Turonian interval from sections of rightbank of the Volga region (the south of the Penza, Saratov and the north of the Volgograd regions). It is suggested to establish two local biozones: Gavelenella cenomanica and Lingulogavelenella globosa within the Melovatkian suite (Senomanian stage).
