From other sources
Taxonomic remark Fossil "Group" created by Versteegh et al., 2009 for spherical calcareous-walled fossils of unknown affinity (some potentially calcareous dinoflagellates), known informally as calcispheres, analogous to term acritarchs/Acritarcha used for organic-walled microfossils of unknown affinity (Evitt, 1963). For convenience, presently assigned to parent group Protozoa in IRMNG although affinities are unknown (or may be with Chromista). [details]
