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
Current identification: Chrysochromulinaceae Edvardsen, Eikrem & Medlin, in Edvardsen et al. 2011Compiled data
Cells predominantly saddle-shaped, with two smooth, equal, homodynamic flagella. Haptonema long to very long and coiling. Flagella and haptonema inserted ventrally and subapically. Cells covered by small organic scales with patterns of radiating and concentric ribs or fibrils. Flagellar apparatus with a simple R1 flagellar root that predominantly contains few microtubules (<10) and lacks a bundle of microtubules. Cells with two yellow-brown chloroplasts each with an immersed pyrenoid. Nucleotide sequences for the SSU and LSU rDNA distinct.
Monogeneric when described.
