Alabushev A.I., Wiedmann J. (1994) Ammonite fauna and genesis of the Santonian/Campanian (Upper Cretaceous) boundary beds of northwestern Kamchatka (north-east Russia) // Neues Jahrbuch für Geologie und Paläontologie, Monatshefte, 1994/9: 528-536.

The untypical Santonian/Campanian boundary sequence near Penzhina Bay, northwestern Kamchatka, contains many well-preserved fossils, especially poorly known ammonites with a predominance of scaphitids. New investigations indicate that these interesting strata comprise deep-water mudstones, and shallow-water turbidites and storm deposits in between. The unusual composition and the modified size of faunas may be connected with hydrodynamical conditions in the oceanic basin.
