  • REVIEW of the UPPER TRIASSIC BRACHIOPODS in the NORTHERN CALCAREOUS ALPS Shallow-Water Carnian Brachiopod Fauna of the NCA Is R
    ©Geol. Bundesanstalt, Wien; download unter www.geologie.ac.at Berichte Geol. B.-A., 76 (ISSN 1017-8880) – Upper Triassic …Bad Goisern (28.09 - 02.10.2008) REVIEW OF THE UPPER TRIASSIC BRACHIOPODS IN THE NORTHERN CALCAREOUS ALPS Miloš SIBLÍK Institute of Geology, Academy of Sciences of the Czech Republic, Rozvojová 269, CZ-16500 Praha 6. [email protected] Shallow-water Carnian brachiopod fauna of the NCA is relatively poor in its diversity (e.g. Adygella and some species of Cruratula and koninckinids in the Raibl and Cardita Beds). It is markedly different not only from partially synchronous assemblages of the Hallstatt Limestone, which lived in deeper parts of the Tethys but totally from those of the Norian and Rhaetian. At that time the diversification of the brachiopod assemblages was already more intensive. The Hallstatt facies yielded already more varied, often smooth fauna of the Carnian and Norian age. The differences in composition between them are rather insignificant. Some brachiopod taxa (Camerothyris, some species of the characteristic genus Austriellula – A. nux, A. longicollis, A. dilatata etc.) are known from both Carnian and Norian levels, some other (terebratulids Nucleatula and Juvavella, athyridid Pexidella strohmayeri, and rhynchonellids Austriellula juvavica, A. laevis, Norella geyeri etc.) are reported from the Norian only. Curious local neptunian dyke “Weisser Crinoidenkalk“ on the GSSP candidate Steinbergkogel near Hallstatt is according to KRYSTYN et al. (2007a) the youngest fossil horizon of the Hallstatt Limestone (top of Paracochloceras suessi Zone). It yielded according to BITTNER (1890) „Juvavella Suessii, Rhynchonella Geyeri, Rhynchonella nux, Koninckina blandula and Spirigera deslongchampsi“, all of them held for the Norian species.
