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.
Taxa are sorted alphabetically for simple browsing, or you can use search boxes at the top & bottom of the page

Editors' Notes
Cellulae diploideae cum coccosphaera, universe mobilis cum coccolithis monomorphis annularibus ex typo cricolithi. Cricolithi elliptici sine fundo caicareo, ex duobus distinctis elementis alternantibus interordinatis incudi similibus compositi. Annulus distalis plus minusve amplus cure elementis imbricantibus aut non imbricantibus.Generatio pseudofilamentosa hapioidea, sine coccolithis, nonnunquam invenitur.
Coccolith-bearing cells diploid, generally motile with monomorphic ring coccoliths of the cricolith type. Cricoliths elliptical with no calcified bottom, formed from two distinct, alternating, anvil-shaped elements fitted together. Distal ring more or less developed with overlapping or non-overlapping elements. Pseudofilamentous haploid generation, without coccoliths, present or not.
