Early Late Campanian ammonite fauna from Busko Zdrój (Nida Trough, southern Poland)

Sixteen ammonite taxa are recorded from four temporary exposures of lower Upper Campanian deposits in the town of Busko Zdrój, NE limb of the Nida Trough, southern Poland. These are: Phylloceras (Neophylloceras) cf. bodei, Tetragonites obscurus, Desmophyllites sp., Pachydiscus (Pachydiscus) subrobustus, P. (P.) cf. subrobustus, Hoplitoplacenticeras (Hoplitoplacenticeras) dolbergense, H. (H.) sp., H. (Lemfoerdiceras) lemfoerdense, Glyptoxoceras cf. retrorsum, G. sp., Lewyites elegans, Pseudoxybeloceras (Pseudoxybeloceras) riosi, Ps. (Ps.) sp. juv., Baculites sp., Scaphites gibbus, and Trachyscaphites spiniger spiniger. Many specimens lack precise provenance data, but co-occurrence of T. obscurus, P. (P.) subrobustus, H. (H.) dolbergense, H. (L.) lemfoerdense, Ps. (Ps.) riosi, Baculites sp., S. gibbus, and T. s. spiniger is documented from a single opoka bed in one of the exposures.The ammonites allow correlation with standard sections in northern Germany: the ammonite-bearing sequence of Busko Zdrój corresponds to a part of the interval from the basiplana / spiniger to roemeri zones in Lńgerdorf and Kronsmoor (Schleswig-Holstein), and from the stobaei / basiplana to vulgaris / stolleyi zones in the Lehrte West Syncline (Lower Saxony). It can also be correlated with the lower part of the Neancyloceras phaleratum Zone in Vistula valley, central Poland.
