摘要：Thirteen species, belonging to eleven genera, i.e., Discinisca Dall, Novocrania Lee and Brunton, Lacazella Munier-Chalmas, Pliothyrina van Roy, Terebratulina d’Orbigny, Megathiris d’Orbigny, Argyrotheca Dall, Bronnothyris Popiel-Barczyk and Smirnova, Joania Álvarez, Brunton and Long, Platidia Costa and Megerlia King, have been identified in the lower Oligocene rocky-shore deposits at Mammendorf, central Germany. The occurrence of the species Discinisca fallens (Wood), Argyrotheca bitnerae Dulai and Megerlia truncata (Linnaeus) extends their stratigraphic range back to the early Oligocene. The affinity to the early Oligocene brachiopod fauna of the Mainz Basin is noted.
