A conulariid preserved in three dimensions from Ordovician fluvioglacial erratics of the Northern European Lowlands (North German Plain) is described under open nomenclature. It is assigned to the genus Conularia with similarities to Baltoscandian conulariids. The lithology of the erratic boulder and fauna contained in it provide important information on the origin and transport direction of the sediment preserved in a kame from the Saalian glaciation. This paper deals with the site of origin of the boulder in Baltoscandia analysing the comprised palaeofauna, from a palaeostratigraphic and palaeogeographic point of view, from its deposition in Ordovician times until its arrival at its current location in the Late Pleistocene. It also reveals for the first time the internal structure of the conulariid aperture.

在开放式命名法下描述了从北欧低地（北德平原）奥陶纪流冰侵蚀性三维保存的一个保形体。它被分配给Conularia属，与Baltoscandian conulariids相似。其中所含的不稳定石块和动物区系的岩性，为有关从萨利期冰期形成的空港中保存的沉积物的起源和运输方向提供了重要信息。本文从古地层和古地理的角度，从奥陶纪时期的沉积直到到达晚更新世的当前位置，分析巴尔托斯堪的巨石的起源位置，从古地层和古地理的角度分析其中的古动物。它也首次揭示了卵形孔的内部结构。
