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.

    Diagnosis: Sarmania is a holococcolith with a prominent solid distal process that either tapers or remains parallel-sided and terminates with a plug. The complete specimens naturally settle in a side-view position. In Sarmania, the distal process is solid and comprises four ridges. The base of Sarmania, as viewed in the plan, features a rim and two pores separated by the base of the solid distal process, which appears as a diagonal cross in the

    Extra details from original publication
    Optical properties: Sarmania is distinguished from Kahvecia, Owenia, and Swapansahooia by its parallel extinction pattern observed at both the base and distal processes. In contrast, Kahvecia, Owenia, and Swapansahooia exhibit inclined extinction patterns. Both Isocrystallithus and Sarmania display parallel extinction but differ in the morphology of their distal processes and the base. In Isocrystallithus, the distal process is hollow, whereas in Sarmania, it is solid and comprises four ridges. The base of Sarmania, as viewed in the plan, features a rim and two pores separated by the base of the solid distal process, which appears as a diagonal cross in the plan view. In comparison, the base of Isocrystallithus in the plan view has a narrow rim and a central opening surrounded by struts.
