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

Remarks: The haptonema of this species, unlike several others in this study, is not easily lost on fixation and is only partially coiled in most speciems (Fig. 19). Plate scales adhere tightly to the cell body and are found in a field surrounding the cell body in dried specimens. In addition, they are exceptionally thin and delicate, making observation of their fine structure difficult and causing many of them to fold (Fig. 20). These scale characteristics are shared with Chrysochromulina fragilis (LEADBEATER 1972b) and Chrysochromulina « aff. fragilis » (MOESTRUP 1979). The proximal scale face exhibits a typical radial pattern divided into four quadrants (Fig. 21). The distal face has a backgroung radial pattern identical to, and possibly showing through from the proximal face. Superimposed on this radial pattern are a series of lines that appear at first to be random, but which on closer inspection can be seen to form a series of irregular, non-concentric circular or ovate lines (Fig. 21). Present at sta. 4/1 m, 6/100 m, 7/35 m, 8/35 m, 9/35 m and 10/35 & 65 m.
