Amoniti spodního a středního turonu české křídové pánve / Lower and Middle Turonian ammonites of the Bohemian Cretaceous Basin

This thesis addresses the systematics and taxonomics of the ammonite assemblages of the Lower and Middle Turonian of the Bohemian Cretaceous Basin (BCB). It describes nineteen species of fifteen genera. Amongst others it concerns: Watinoceras coloradoense (Henderson), Spathites (Jeanrogericeras) reveliereanum (Courtiller), Paramammites sp. cf. P. polymorphus (Perervinquière), and Lecointricecras carinatum (Kennedy et al.) from the BCB, which have been described for the very first time. Another important taxon that is described is Prionocyclus albinus (Fritsch), which has not been encountered in the BCB since the year 1872 when it was established as a holotype by A. Fritsch. This specimen is now deposited in the National Museum in Prague. Most of these significant taxa belong to the collection of Dr. J. Soukup. He collected the specimens in various locations near Žďánice u Kouřimi mainly in the first half of the 20th century. The locations no longer exist. Stratigraphically important zonal ammonites, primarily W. coloradoense and Fagesia catinus (Mantell), are a direct evidence of the presence of two ammonite zones in the lower Lower Turonian in this part of the BCB (the zones Watinoceras coloradoense/devonense and Fagesia catinus). They also illustrate a larger stratigraphical extent of...
