摘要：
A very diverse, early Oligocene mollusc assemblage of the Mammendorf quarry nearby Magdeburg includes many Fissurellidae. Most of them belong to Emarginula species but some small, highly conical shells possessing a typical internal septum belong to the extant genus Cornisepta MCLEAN 1998. Two species could be observed: Cornisepta anhaltina lisp. having a smooth shell, and C. granulocostata n. sp. with granulose radial costae. Both species represent the first fossil record of that genus or the North Sea Basin.
