Original descriptions of taxa. For coccolithophores, and many calcispheres, these are pages from the 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 compiled by Prof A. Farinacci 1969-1989 and updated by Richard Howe 2000-2016 - see also this page.
Taxa are sorted alphabetically for simple browsing, or you can use search boxes at the top & bottom of the page

Oval to sub-circular shield, far greater than the proximal shield shield, the central oval clouds perforated sieve. Very far from the shield than 54-60 elements clockwise slightly overstep made jagged edge of the shield; very far wall Epistar wide, the number of pole shield away the same. Distal surface of the shield smoother, its wafer number and far very same shield. Near the central perforated mesh attached to the pole face shield, ranging from small-diameter large, the number of perforations is 54-64 months.
In the orthogonal polarization, shield-shaped plate was light extinction.
Sample size, very far from the long axis of the shield 4-5μm, minor axis 3.5-4.5μm; the long axis of the proximal shield 3.3-4μm; hole net diameter 0.9-1.5μm.

Compare discuss current new species compared with R. laevis, the latter very much the shield plate wafer (140), the small number of cells (30-40) and distinguished from each other.

Horizon Oujiang group. [Mid Eocene NP13-17 cf. Wan et al. 2014 Palaeogene marine stratigraphy in China, Lethaia 47, 297-308]
