Sister taxa: S. mediterranea, S. maxima, S. sp. Y

Farinacci & Howe catalog pages:


Morphology: Figured by Kleijne (1993, pl. 3:3) as C. mediterranea, and by Winter et al. (1979, pl. IV fig. 2), as C. mediterranea.


Biology & life-cycles: HOL ?= Calyptrolithina cf. multipora. A single combination coccosphere, illustrated by Young et al. 2003 (plate 23, figs 9, 12) was found by Vita Pariente in the Gulf of Mexico. Definitive identification is not possible but it appears to consist of the same Coronosphaera species and a holococcolith similar to Calyptrolithina multipora, although with less pores than is usual.
