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

Diagnosis: Coccolithi pappolithiformi; margo anguste muriformis exteriorem versus leviter inclinatis, muro assulis speciarum duarum alterne verticalium tangetialiumque dispositis formato; altera species parva partio proximali muri limitata, altera species assulae verticaliter expansa; processus centralis saepe praesens.
