The brachiopods from the Kadzielnia limestone (Frasnian) of the Holy Cross Mts

Abstract

The lowermost part of the Kadzielnia limestone contains a very differentiated brachiopod·fauna, usually occurring in gregariously crowded monospecific clusters. The brachiopods constitute the richest faunistic assemblage after the stromatoporoids, tabulate and rugose corals. Twenty one brachiopod species are stated, one new; some of them are not assigned to definite species owing to the unsatisfactory stats of preservation and/or insufficient number of specimens. Stratigraphically, the brachiopods all belong to the Frasnian species and indicate the lowermost part of the Kadzielnia limestone to be of Upper Devonian age.
