E-mail: [email protected] ABSTRACT: REMIN, Z. 2004. Biostratigraphy of the Santonian in the SW margin of the Holy Cross Mountains near Lipnik, a poten­ tial reference section for extra-Carpathians Poland. Acta Geologica Polonica, 54 (4), 587-596. Warszawa. The set of outcrops near the village of Kije, on the SW margin of the Holy Cross Mountains provides a nearly com­ plete Santonian succession that has a great potential to become a Santonian reference section in Poland. The Coniacian/Santonian boundary is defined here by the first occurrence (FO) of the inoceramid bivalve species Cladoceramus undulatoplicatus (ROEMER 1852). The uppermost Santonian is characterized by common Sphenoceramus patootensiformis (SEITZ 1965). The top of the stage (and the base of the Campanian Stage) is docu­ mented by the last occurrence (LO) of the crinoid species Marsupites testudinarius (SCHLOTHEIM 1820). The substage division of the Santonian is based on inoceramids, with the lower boundary of the Middle Santonian indicated by the LO of Cladoceramus undulatoplicatus and the base of the Upper Santonian by the FO of representatives of Cordiceramus muelleri (PETRAS CHECK 1906) group. Keywords: Cretaceous, Santonian, Stratigraphy, Biostratigraphy, Magnetostratigraphy, Ammonites, Inoceramid bivalves, Crinoids. INTRODUCTION study, the Lipnik section may become a standard reference section for the Santonian in extra-Carpathians Poland.

OZANNE Department of Geology, University of South Florida, 4202 E. Fowler Ave., SeA 528, Tampa, FL 33620-5201 USA. E-mail: [email protected] ABSTRACT: HARRIES, P.I. & OZANNE, C.R. 1998. General trends in predation and parasitism upon inoceramids. Acta Geologica Polonica, 48 (4), 377-386. Warszawa. Inoceramid bivalves have a prolific evolutionary history spanning much of the Mesozoic, but they dra­ matically declined 1.5 Myr prior to the Cretaceous-Tertiary boundary. Only the enigmatic genus Tenu­ ipteria survived until the terminal Cretaceous event. A variety of hypotheses have attempted to expla­ in this disappearance. This study investigates the role that predation and parasitism may have played in the inoceramids' demise. Inoceramids show a range of predatory and parasitic features recorded in their shells ranging from extremely rare bore holes to the parasite-induced Hohlkehle. The stratigraphic record of these features suggests that they were virtually absent in inoceramids prior to the Late Turonian and became increasingly abundant through the remainder of the Cretaceous. These results suggest that predation and parasitism may have played a role in the inoceramid extinction, but more rigorous, quantitative data are required to test this hypothesis further. Probably the C011lmonest death for many animals is to be ous-Tertiary boundary (KAUFFMAN 1988). The mar­ eaten by something else. ked demise of such an important group has led to the C. S. Elton (1927) formulation of a wide range of hypotheses to explain this phenomenon.

Integrated biostratigraphy of the San- tonian through Maastrichtian (Upper Cretaceous) of extra-Carpathian Poland. Acta Geologica Polonica, 66 (3), 313–350. Warszawa. The biostratigraphic importance, current zonations, and potential for the recognition of the standard chronos- tratigraphic boundaries of five palaeontological groups (benthic foraminifers, ammonites, belemnites, inoceramid bivalves and echinoids), critical for the stratigraphy of the Santonian through Maastrichtian (Upper Cretaceous) of extra-Carpathian Poland, are presented and discussed. The summary is based on recent studies in selected sec- tions of southern Poland (Nida Synclinorium; Puławy Trough including the Middle Vistula River composite sec- tion; and Mielnik and Kornica sections of south-eastern Mazury-Podlasie Homocline) and of western Ukraine (Dubivtsi). The new zonation based on benthic forams is presented for the entire interval studied. Zonations for ammonites, belemnites and inoceramid bivalves are compiled. All stage boundaries, as currently defined or un- derstood, may easily be constrained or precisely located with the groups discussed: the base of the Santonian with the First Occurrence (FO) of the inoceramid Cladoceramus undulatoplicatus; the base of the Campanian with the Last Occurrence (LO) of the crinoid Marsupites testudinarius and approximated by the range of the foraminifer Stensioeina pommerana; and the base of the Maastrichtian approximated by the FO of the inoceramid bivalve Endocostea typica and the FO of the belemnite Belemnella vistulensis.

  • Between the Alb and the Alps – the Fauna of the Upper Cretaceous Sandbach Formation (Passau Region, Southeast Germany)
    Between the Alb and the Alps The fauna of the Upper Cretaceous Sandbach Formation (Passau region, southeast Germany) SIMON SCHNEIDER, BIRGIT NIEBUHR, MARKUS WILMSEN & RADEK VODRÁKA Situated halfway between the Franconian Alb and the Northern Calcareous Alps, the uppermost Turonian to basal Middle Coniacian sediments of the Sandbach Formation (Ortenburg–Passau area, Lower Bavaria) provide valuable information on an area largely devoid of Cretaceous sediments at the surface. Based on the rediscovered classic collection of Gustav von Stockheim, the facies and fauna of the two subunits of the Sandbach Formation, i.e., the Marterberg and Buchleiten mem- bers, are described, illustrated, and evaluated with regard to palaeoecology. The fauna comprises 53 taxa in total. Almost two-thirds of these are bivalves, which also dominate the eutrophic distal inner shelf assemblage of the Marterberg Mem- ber. Conversely, the mid- to outer shelf fauna of the Buchleiten Member is dominated by siliceous sponges, which flour- ished on account of continuous deepening and decline of terrigenous input during transgression. • Key words: invertebrate macrofauna, Turonian, Coniacian, palaeoecology, Danubian Cretaceous Group.
