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.
Taxa are sorted alphabetically for simple browsing, or you can use search boxes at the top & bottom of the page

    • Editors' Notes
    Tan Sin Hok (1927, 1931) did not follow standard nomenclatural practice and left a confusion of generic names - Discoaster, Eu-discoaster, Hemi-disocaster and Helio-discoaster. These are discussed by, in particular, Loeblich & Tappan (1963), Prins (1971), Theodoridis (1983, 1984), and Doweld (2014). Doweld (2014) made a formal proposal to the ICN to conserve Discoaster and supress Eu-discoaster, Hemi-discoaster and Helio-discoaster and to designate D. brouweri as the type species (Loeblich & Tappan 1963 had earlier sought to designate D. pentaradiatus as type species, but this was not done correctly and so was meaningless according to Doweld 2014).

    The proposal of Doweld (2014) was approved, as reported by Herendeen (2016), and ratified by the ICN. Hence Discoaster is a fully valid genus, with the type D. brouweri. [my notes JRY, 2022]

    NB Tan Sin Hok came from a chinese Indonesian family and his family name was Tan, not Hok, see Munasri & van Gorsel (2014).

    (3) The original publication details for Discoaster S.H. Tan, 1931 are Tan, S. H. (1931). Discoasteridae, Coccolithinae and Radiolaria. In: B.G. Escher et al. (eds.) De palaeontologie en stratigraphie van Nederlandsch Oost-Indie, Feestbundel K. Martin, Leidsche Geol. Meded. 5, p. 92-114. - published on p. 93 according to Doweld.

    (2) Tan Sin Hok published under that name as written out, however according to his biography Tan is the family name, Sin Hok the given names, therefore his authorship (and published works) should preferably be cited as "S.H. Tan" (or "S.H.Tan", no space, if you strictly follow the IPNI format, which I don't...) - see https://www.ipni.org/a/31495-1 .

    Hi Jeremy... some points regarding Discoaster, and other taxa from this author, if I may...

    (1) Although the Farinacci catalogue regard Discoaster as an emendation of Eu-discoaster, and therefore dates it to the year for the latter (1927), the cited work by Doweld, 2014 (as accepted by Herendeen, 2016) treats Discoaster as a new name first published in 1931 and therefore should be cited with that date, which is also accepted by Index Nominum Genericorum as at now.

    Thanks - I've changed the citation date to 1931. I agree with you on IPNI format, it is a hideous system and trying to follow it would be pointless waste of time.
