Distinguishing features:
Parent taxon (Dinophytes):
This taxon: Calcareous dinoflagellates
Taxonomy:
As in the haptophytes, it appears likely that calcfication evolved only once in the group. Calcification has however been lost several times since various non-calcifiying dinophytes occur in the Thoracosphaeraceae, these forms are not included here.
