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
Translation (JRY - 2019)
This genus is characterised by a shell that is reguarly elongated in a shuttle-shape, the extremities of which are very extended as a result of a diminution of the scapholiths in size and number. The scapholiths at the moment of their formation have a unorganised base, whilst with maturity of the cell the base becomes organised into a definite structure of the ladder type. [NB scalae is the plural of the latin word scala - ladder]
Extra details from original publication
Translation: This new genus is close to Anoplosolenia, however it is differentiated by the appearance of the shell and by the special structure of its scapholiths
