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: The suborder Eiffellithineae, consisting of loxolith calcareous nannofossils, is characterized by single or double walls. The outer wall shows constant extinction under cross-polarised light (XPL) and comprises sinistrally imbricated segments. The inner wall segments may be arranged in imbricated, protolith, or tangential patterns, often exhibiting interference colours. The central area may contain structures such as axial or diagonal crosses or bars, which usually bear a distal process.
