Middle Miocene (Badenian) brachiopods from coral reefs of north-western Bulgaria

Abstract

The brachiopod assemblage from the Middle Miocene (Badenian) coral reefs of north-western Bulgaria comprises five species, viz. Ancistrocrania abnormis (DEFRANCE), Argyrotheca cuneata (RISSO), A. cordata (RISSO), Platidia sp., and Thecidellina sp., all of which are reported for the first time from the Miocene of Bulgaria, and Thecidellina being first noted from the Paratethys. The composition of the brachiopod fauna from Bulgaria displays the resemblance to other brachiopod assemblages of the Paratethys.
