Original descriptions of taxa - also emended descriptions for a few 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.

Combinations:
  • Discoaster challengeri Bramlette & Riedel 1954 (basionym) as used in the literature, but not including the holotype. The name D. challengeri clearly has priority over D. variabilis but it was based on an ambiguous drawing of an Early Miocene specimen, probbly belonging to the D. exilis group. Most specimens which have been identified as D. challengeri in the literature, however, fall readily within D. variabilis

  • Editors' Notes
    This is a problematic species name since it has priority over most other speices but the type drawing does not obviously resemble any Early Miocene discoaster. The name has mostly been applied to Discoaster variabilis specimens.  [my interpretation - JRY 2020]
