Inarticulate brachhiopods from Lower Ordovician of the Holy cross Mountains, Poland

Two inarticulate brachiopod assemblages are recognized in the Lower Ordovician of the Holy Cross Mountains, Poland, as characteristic of the local Lingulella zejszneri and Acontiodus rectus sulcatus zones. They occur with conodonts typical of the Scandinavian Paltodus deltifer and Baltoniodus navis + Baltoniodus triangularis Zones. One new genus (Quasithambonia) and five new brachiopod species: Rowellella distincta, Quasithambonia rarispinosa, Spondylotreta maior, Scaphelasma bukowkense, Eoconulus dyminensis are established from the Acontiodus rectus sulcatus
