Wall formed of crystals with tangential c-axes (Thoracosphara s.l.)

Wall formed of crystals with radial c-axes (Orthopithonella s.l.)

Wall formed of crystals with radial c-axes (Obliquipithonella s.l.)



These taxa are generally accepted in the calcisphere literature, even if their affinities are not sure

Described taxa included in the Farinacci catalog but not included elsewhere (mostly poorly documented taxa)

Taxonomy:

Synonyms:
Notes & discussion: Here the classification of calcareous dinoflagellates is summarised - based mainly on papers of Streng. The most common extant species are grouped in one category for now, to make it easier to find them

See also: Mesozoic non–coccoliths- Mesozoic taxa commonly found in nannofossil preps are still dealt with in Mesozoic nanofossils;
