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 Calciodinelloid dinoflagellate cysts built by a single calcareous layer. Crystals of the calcareous cyst wall layer are oriented with their crystallographic c-axis tangential to the cyst surface. Paratabulation patterns are present. The operculum includes apical, intercalary, and precingular plates. Epicystal archeopyle. Etymology: Latin: lebes Extra details from original publication Discussion. A calcareous dinoflagellate genus with an epicystal archaeopyle has not yet been described. Large archaeopyles are present in species of the genera Scrippsiella and Pernambugia as well (Janofske 2000, Janofske and Karwath 2000), but a paratabulation given by the reflection of precingular plates in the operculum is not present. Therefore we suggest the new genus Lebessphaera that contains all cysts with tangential wall structure and an epicystal archaeopyle. A cyst–theca relationship is not given here, because cysts of this new genus could not be germinated successfully in cultures.
