Brachiopods from the Sanadinovo Formation (Lower Cenomanian) in northern Bulgaria

Brachiopod faunas from the Early Cenomanian Sanadinovo Formation in northern Bulgaria comprise seven species in five genera, namely Cyclothyris sp., Concinnithyris subundata (J. Sowerby), Terebratulina imbricata Owen, T. etheridgei Owen, Terebratulina sp., Kingena concinna Owen and Modestella geinitzi (Schloenbach). With the exception of Cyclothyris, all are recorded for the first time from the Upper Cretaceous of Bulgaria; the present records extend the geographic distribution of these taxa from England, northern France and Poland to central-northern Bulgaria, which, during the Late Cretaceous, was situated along the southern margin of the North European epicontinental sea.
