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.

Editors' Notes
Cretaceous species which were once assigned to Tetralithus are now placed in Micula, Ceratolithoides, Calculitesand Uniplanarius. The generic description does not really correspond to any obvious nannofossil and possibly was based on a diagenetic crystal.
