Foraminifera note details
Cushman (1944): "Articulina compressa Reuss (Neues J ahrb. fur Min., 1853, p. 673, pl. 9, fig. 3). This is from the Miocene of central Europe. The figure shows a compressed form with three visible chambers apparently arranged in a planispiral manner, the wall costate and the aperture with a thickened lip. This may possibly be the young stage of an Articulina, but no material was available to furnish further evidence of the adult stages."
