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

Citation: Olladiscoaster molae Varol & Bowman 2024Taxonomic rank: speciesType specimens: Holotype: Plate 25, Figs. 1-24 (same specimen in mobile mount) Type age (chronostrat): Zone NN6, Middle Miocene. Type locality: USGS-NASA Langley core Hampton, VA, USA. Type repository: Varol Research, LlandudnoRepository Country: Wales
Original Description Hexagonal stellate species of Olladiscoaster have diamond-shaped segments with quasi-arms. The tips of the segments are often pointed. On the distal side, the distinct windmill-like sutural ridges are created by the deep cavities. The sutural ridges are raised towards the centre and capped by kiteshaped distal covers. The distinct proximal ridges with a petaloid knob decorate the bulged proximal side. At the side view, Olladiscoaster molae resembles a bouquet. Size: Dimensions of holotype: Maximum diameter: 6.79 µm, Maximum height: 4.67 µm; Diameter of the central area: 4.30 µm, Diameter of the proximal knob: 3.20 µm, Height of the proximal knob: 1.25 µm, Length of the quasi-arm: 1.24 µm, (measurements from bright field micrograph). Etymology: From the Latin molae, mill - refers to its windmill-like appearance. Extra details from original publication Remarks:Olladiscoaster mollae differs from all other Olladiscoaster species by its windmill-like appearance.
Occurrence: This species is recorded from IODP Leg 354, Hole 1451B, Ninetyeast Ridge, Bengal Fan, Indian Ocean, USGS-NASA Langley core 134.4 m, Hampton, VA, USA and various commercial oil wells in the Gulf of Mexico.
