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 marginal area constructed of two petaloid cycles of elements which are not at all, or only very slightly, imbricate. The marginal areas of members of this order have a characteristic appearance in bright phase field phase contrast illumination, being much darker than the background. Editors' Notes Introduced as Podorhabdinales but the correct form for an ordinal name based on Podorhabdus is Podorhabdales.
