Brachiopods from Terebratula Bed from the Upper Muschelkalk in the Grotów P-11 borehole (SW Poland)

Abstract

Morphologic studies on the brachiopod assemblage from the Terebratula Bed from the Upper Muschelkalk in the Grotów P-11 borehole showed the occurrence of Cocnothyris vulgaris (Schlolheim), C. cycloides (Zenker) and “Coenothyris” sp. Specimens of C. cycloides (Zenker) are distinctly dominant in the shell conglomerate. In comparison to the material known from Thüringen, Wòrttemberg and the Holy Cross Mts. are the studies done have proved that in the territory of Poland the Terebratula Bcd - an equivalent to Cycloidesbank γ-contains more than one brachiopod species.
