Stratigraphy and ammonite fauna of the Cenomanian of Westphalia

Journal article

The Cenomanian ammonitefaunas of the Munster Basin are systematically and stratigraphically revised. They comprise 75 species, referred to 33 genera. In addition to SCHLUTER's (1871-1876) type-material, the specimens figured by WIEDMANN AND SCHNEIDER (1979) and KAPLAN, KELLER AND WIEDMANN (1985) are redescribed and partially refigured. The ammonites occur in four different facies associations: the arenaceous glauconitic Essen-Greensand in the west, the red limestone pocket of Muhlheim-Broich within the Essen Greensand depositional area, the Planer limestone-facies in the east, and chalks in the north of the Munster basin. The ammonite occurrences are described in the context of biostratigraphy, of regional lithostratigraphy, sequence stratigraphy, and cyclostratigraphy. The ammonite zones recognized are closely comparable to those of the Anglo Paris basin, especially these of southern England. The bio- and event stratigraphic correlation with the Cenomanian of Poland, Mangyshlak and the Crimea is described and discussed.
