Alifirov A.S. (2009) Ammonite scale for the Volgian of Western Siberia and its paleontological substantiation // Stratigraphy and Geological Correlation, Vol. 17, No. 6, P.632–644.

The revision of available identifications of Volgian ammonites from the core of boreholes drilled in Western Siberia allowed for the refining of the list of genera and species established on its territory. The lack of reliable identifications of a series of taxa indicates an imperfectly substantiated subdivision of individual Volgian zones of the Subpolar Urals in Western Siberia. The Volgian zonal scale of Western Siberia is proposed to be put into correspondence with its actual paleontological substantiation. Although the scale leans upon the North Uralian one, it is less detailed as compared to the latter.
