Original descriptions of taxa - also emended descriptions for a few 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

    Diagnosis: Elliptical coccoliths with an eiffellithalid rim and six or more bars disposed symmetrically with respect to the axes of symmetry of the ellipse. A spine may arise from the point of juncture of the bars in the center of the coccolith. In addition to the type of genus, Pontilithus Gartner, 1968, belongs here.
