Abstract

The brachiopod fauna of the Lower Cretaceous Bersek Marl (Gerecse Mountains, Hungary) is briefly described. The scanty material of the historical collections consists of 26 specimens, mostly from the Hauterivian of the Bersek Hill, and 6 specimens from the Valanginian of Nyagda Ravine. Only two species of a single genus have been identified: Triangope triangulus (VALENCIENNES in LAMARCK, 1819) and T. cf. rectangularis (PICTET, 1867). An intriguing feature of the material is that the valves are almost always strongly deformed or distorted by the compaction of the marly sediment. The genus Triangope is regarded as a marker of deeper or calmer marine environments and a characteristic Tethyan element of the Mediterranean faunal province.
