Lingulate brachiopods from the Vinařice Limestone (Devonian, Pragian) of the Barrandian area, Czechia

The Vinařice Limestone (Praha Formation; Central Bohemia) of Pragian age contains a moderate diverse lingulate brachiopod fauna including a new species of discinid, Acrosaccus robustus sp. nov., associated with several other poorly preserved discinids including the trematid Schizocrania , one species of the biernatid Havlicekion and fragments of an obolid. Lingulate brachiopods are associated with diverse rhynchonelliformean brachiopods mainly strophomenoids and rhynchonelloids. Brachiopods, trilobites and other fauna confirm the presence of a shallow, rough-water environment that existed before the origin of the coral-stromatoporoid-algal Koněprusy reef in the area. The lingulate brachiopod assemblage described herein differs from the local Emsian (Suchomasty Limestone) and Eifelian (Acanthopyge Limestones) lingulate brachiopod assemblages by absence of the discinid Chynithele. Presence of Schizocrania sp. indicates derivation of the fauna from the Lochkovian brachiopod assemblage. An Oichnus - type drilling trace in the brephic shell is documented in the discinid Praeohlertella ? sp. •
