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 complied 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.

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.
