Lingulate brachiopods from the Kotýs Limestone (Lochkov Formation, Lochkovian) from Branžovy ridge near Bubovice (Barrandian area, Czech Republic)

Abstract

Lingulate brachiopods are described from an outcrop of the Kotýs Limestone (Lochkovian) at Branžovy ridge near Bubovice in Central Bohemia (Czech Republic). Twelve species are systematically described. Two new genera and species, Rarepora tumulamen gen. et sp. nov. (Family Obolidae) and Branzodiscus porosus gen. et sp. nov. (Family Discinidae) are erected, and one new species Paterula postsilurica sp. nov. is described. Four formerly described species (Barrandeoglossa perneri, Lochkothele intermedia, Opsiconidion holynensis and Orbiculoidea magnifica) are recognised and six other species are left in the open nomenclature being more or less tentatively affiliated with the genera Kosoidea, Praethele and Schizotreta. The lingulate brachiopods come from beds that yield abundant, diverse and well silicified rhynchonelliform brachiopods, rugose and tabulate corals, and diverse epibiontic invertebrates (craniids, bryozoans, graptolites, microcrinoids, byroniids).
