Original descriptions of taxa. For coccolithophores, and many calcispheres, these are pages from the 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 compiled by Prof A. Farinacci 1969-1989 and updated by Richard Howe 2000-2016 - see also this page.
Taxa are sorted alphabetically for simple browsing, or you can use search boxes at the top & bottom of the page

Editors' Notes

van Heck (1980, INA Newsletter 1/2 p. 39) noted that: In 1961, Stradner introduced Heliorthus tenuis. In 1963, he transferred this species to the genus Coccolithus. However, the combination Coccolithus tenuis already existed, having been introduced by Kamptner in 1937 for a different species. To avoid homonymy, Stradner introduced the name Coccolithus helis for his species.

When Hay and Mohler in 1967 transferred the same species to the genus Cruciplacolithus, they correctly used the name  'tenuis' again, following Art.55 of the ICBN. This article states that, "when transferred to another genus .... the specific epithet ... must be retained .... or must be reinstated, unless an earlier legitimate specific epithet is available."
