Citation:
Cryptococcolithus mediaperforate (Varol, 1991) de Kaenel and Villa, 1996 [Birkelundia]Description: Elliptical, medium sized placolith. Central-area with coarse grill clearly visible in LM (non-birefringent but easily seen in phase contrast). Proximal shield is birefringent but thin, and often detached, so coccolith is characteristically dark in XPL.
Remarks: Rare and easily overlooked but a distinctive species.
Range: NN3 to 11.
Synonym: Cryptococcolithus takayamae Gartner, 1992.
