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 Coccoliths with a simple marginal area (eiffellithalid rim) consisting solely of a
;
double cycle of elements the two cycles are superposed in such a way that they appear as
a single cycle in most proximal and distal views, a suture being visible only on the inner surface of the circlet, facing the central area. Central structures are variable, con¬ sisting of a cross, bar or more complex feature which may be surmounted by a spine.
