Unidentified extant holococcolith

Classification: ntax_cenozoic -> Holococcoliths -> Unidentified extant holococcolith
Sister taxa: tubeless, convex, bridged, flat-topped, septate, open-tube, fossil holococcoliths, U. extant holococcolith


taxonomic rank: generic level id
Taxonomic discussion: Unidentified extant holococcolith. In the light microsocope it is often impossible  to identify holoccolith-bearing species so this category is quite often used in plankton counts.
