Descriptive info Upper Cretaceous; Baltic. (Index Nominum Genericorum) [details]
Taxonomic remark From Schrank, 2003: The genus Cymatiosphaera was treated as a junior synonym of the prasinophyte genus Pterosperma by Parke et al. (1978), but it was retained as a separate genus by subsequent authors (e.g. Tappan, 1980; Fensome et al., 1990). Cymatiosphaera was also regarded as a senior synonym of Cymatiosphaeropsis Mädler (1963) because the diagnostic features of the latter (presence of granules in the septate fields) were interpreted as of specific rather than of generic rank (Eisenack et al., 1973; Playford, 1977; Fensome et al., 1990). This is supported by the high variability of granulations (granules may be present or absent in septate fields of the same specimen) in Cymatiosphaeropsis-like specimens in the present material. However, the type species of Cymatiosphaera has other features (high membranes supported by stout distally bifurcating processes; Cookson and Eisenack, 1960), which do not occur in Cymatiosphaeropsis and in many Cymatiosphaera species and which could serve as valid generic characters. ... Cymatiosphaera is a large, long-ranging genus (about 139 species, Early Cambrian to Pleistocene; Fensome et al., 1990), and the morphology of its type species is not clear (see above). It is possible that the genus in its current sense is heterogeneous and that it includes representatives of different algal groups. [details]
