Rogov M.A. (2016) New Zonal and Infrazonal Scales for the Kimmeridgian in Western Siberia based on Cardioceratid Ammonites // Stratigraphy and Geological Correlation. Vol. 24. No. 5. P. 503–526. DOI: 10.1134/S0869593816050051

It is proposed to use a Boreal scale based on the succession of cardioceratids (with the Bauhini, Kitchini, Sokolovi, and Decipiens zones) for the subdivision of the Kimmeridgian of Western Siberia instead of the aulacospephanid-based Subpolar Urals scale which was traditionally used in this region. It is shown that the use of the Boreal scale allows a finer subdivision and correlation of the Kimmeridgian of Western Siberia. A complete succession of zones and subzones based on cardioceratids and several biohorizons previously established in western Arctic are confirmed. The infrazonal Kimmeridgian scale of Western Siberia is correlated with the scales of Franz Josef Land, Spitsbergen, and northern Central Siberia. The diagnosis and ranges of Plasmatites zieteni (Rouill.), characteristic of the basal part of the Kimmeridgian (zieteni biohorizon), are given. The new species Amoeboceras (?) klimovae Rogov, sp. nov. and Amoebites peregrinator Rogov, sp. nov. (index species of the biohorizons recognized by the present author) are described
