Current knowledge of ammonite assemblages from the Štramberk Limestone (Tithonian-lower Berriasian) at Kotouč Quarry, Outer Western Carpathians (Czech Republic)

Forty-two species of perisphinctoid ammonites from the Štramberk Limestone at Kotouč Quarry near Štramberk (Moravia, Czech Republic) have been taxonomically assessed since 2013. Some of these species are contained in old collections at various Moravian-Silesian museums, while others are in the collections of two of us (ZV and PS); all are from Kotouč Quarry. In view of the fact that the Štramberk Limestone usually lacks distinct bedding, the stratigraphical position (ammonite zones) of the taxa identified is derived from literature data. Ammonite species identified document the entire Tithonian to the lower Berriasian. One taxon of early Berriasian age is described as new, Neocosmoceras eliasi. The Tithonian ammonite assemblage, with the exception of the uppermost portion of that stage, is close to those on record from the Mediterranean bioprovince in adjacent countries. In the uppermost Tithonian, a cosmopolitan species, Substeueroceras koeneni, appears. In the lower Berriasian, in addition to Mediterranean representatives, taxa that are known from the Crimean Peninsula and, exceptionally, those from the Subboreal Russian Platform Basin, are present.
