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.

  • Original Description

    Diagnosis: Small elliptical coccolith consisting of a non-birefringent outer cycle and birefringent inner cycle.

    Description: This elliptical coccolith is made up of two cycles of elements. The outer cycle is non-birefringent whilst the inner cycle is birefringent. No structure was observed in the central area. Examination under SEM is necessary to understand the true structure of this small species.

    Etymology:
    In honour of the late Dr. Brian J. O'Neill, colleague, Shell international E&P, Houston, Texas, USA

    Extra details from original publication
    Remarks: An influx of this small species was recorded between NN7 and lower NN10 in all studied locations.

    Occurrence: This species is restricted to Zones NN7-NN10 where it is in great abundance. Syracosphaera? oneillii is observed in sediments from the Philippines, Vietnam, Malaysia, Indonesia, the Gulf of Aden, West Africa, Brazil and Trinidad.
