Original descriptions of taxa. For coccolithophores, and many calcispheres, these are pages from the Farinacci & Howe Catalog of Calcareous Nannofossils. In other cases (e.g. non-calcifying haptophytes) the data is directly compiled on this site. The "Catalogue of Calcareous Nannofossils" was originally compiled by Prof A. Farinacci 1969-1989, since 2000 it has been updated and extended by Richard Howe - see The Farinacci and Howe Catalog - an Introduction.

Bemerkungen: Semihololithus underscheidet sich von den holococcolithischen Gattungen wie Zygrhablithus, Holodiscolithus, Lanternithus und Orthozygus durch das Vorhandensein von heterococcolithischen Teilen des Coccolithen.
