Abstract

The Carpatho-Cimmerian bioprovince is a Barremian–lower Aptian entity. Its definition based on the coexistence of two calcareous algae and a foraminifera, is well supported by a distinctive rudist assemblage. Thirteen species: Requienia zlatarskii, Lovetchenia lovetchensis, Lovetchenia drinovi, Lovetchenia stratechi, Toucasia petersi, Parapachytraga gigantea, Paragyropleura paquieri, Debrunia ? dibrariana, Debrunia ? kafanensis, Homopleura balkanica, Homopleura ? minima, Homopleura? gigantea and Bicornucopina petersi are characteristic, endemic members of this bioprovince. The Carpatho-Cimmerian bioprovince shared some taxa with Western Europe and Apulian biomes. The Carpatho-Cimmerian rudist assemblage extends from Hungary, Romania, Bulgaria, Slovakia, Ukraine, Southern Russia, Northern Turkey, Armenia, Azerbaidjan and probably Turkmenistan. The South Bohemian shelfal discontinuity between the Western European and the Balkanic regions, accounts well for the dissimilarity of the corresponding faunas.
