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

Original Description Diagnosis: Elliptical coccoliths with an eiffellithalid rim and a complex central structure consisting of either (1) six or more bars disposed symmetrically with respect to the major and minor axes (Subfamily Actinozygoideae, new subfamily), or, (2) four or more bars disposed asymmetrically in such a way that one end of the coccolith may be duplicated by rotation of the other end through 180 degrees (subfamily Diadozygoideae, new subfamily).
