- According to the present authors the decline of the Bajocian crinoidal limestone sedimentation in the Pieniny Klippen Basin corresponded to a general subsidence of the Czorsztyn Ridge which promoted the appearance of nodular limestones of the pelagic Ammonitico Rosso facies (Czorsztyn Limestone Fm., Niedzica Limestone Fm.). As proved by ammonite faunas recognized in the Czorsztyn, Niedzica and Czertezik successions, this replacement of the facies (sometimes related with hiatus) took place during the latest Bajocian. A different interpretation of stratigraphy of the crinoidal limestones is given by Birkenmajer (1977, 2007) who postulates a wider stratigraphical range of these deposits, in the Czertezik Succession, but also in the Czorsztyn Succession, from the Bajocian up to base or even end of the Callovian. According to this author the crinoidal limestones span in these two successions a large stratigraphical interval of the Middle Jurassic being partly a lateral equivalent of the nodular limestones of the Niedzica Limestone Fm. of the Niedzica Succession. The present authors investigations, based on new findings of ammonites (parkinsoniids—Parkinsonia (Parkinsonia) parkinsoni (Sow.), Parkinsonia cf. bomfordi Arkell), in the typical area of occurrence of the Czertezik Succession, indicate the presence of the uppermost Bajocian–lowermost Bathonian red nodular limestones of the Niedzica Limestone Formation, and along with older ammonite datings from the Czorsztyn Succession prove that the onset of sedimentation of the nodular limestones was almost coeval in the Czertezik Succession, the Czorsztyn Succession and the Niedzica Succession. Additionally, the ammonite fauna indicates that sedimentation of the crinoidal limestones in the Czertezik Succession took place during the Bajocian, similarly as in other successions of the Pieniny Klippen Belt. These new findings show that differences between the Czertezik Succession, and other successions of the Pieniny Klippen Belt are much smaller than hitherto proposed (Birkenmajer, 1959), and confirm an earlier interpretation of the present authors (Wierzbowski et al., 2004).
