Taxonomy:

Citation: Calciosolenia corsellii Malinverno, 2004

Rank: Species

Variants:

Calciosolenia tropicus Patil et al. 2020 (separated from C. corsellii on the grounds that the R-units are more prominent on the proximal surface - this is both an impossible criterion to apply in most cases and a feature which varies with degree of calcification and state of preservation [my interpretation - JRY 2021])

Taxonomic discussion: This species has probably often been included in C. brasiliensis

Distinguishing features: Coccosphere without spines, coccoliths 3-4µm long, with spurs at the ends

Farinacci & Howe catalog pages: C. corsellii * , C. tropicus [no catalog entry yet]

Morphology: Coccosphere similar to C. brasiliensis but coccoliths more like those of C. murrayi in size (3-4µm long), number of laths, and in presence of spurs at the ends of the coccoliths.
For identification note that the liths usually are similar in size to an E. huxleyi coccolith and have separated laths.

Size: Liths 3-4µm long

Ecology & Biogeography: Described from the Mediterranean but also certainly occurs in the Atlantic (Young unpubl. obs.) and probably globally

Geological Range:
Last occurrence (top): Extant Data source: present in the plankton (Young et al. 2003)
First occurrence (base): within Quaternary Period (0.00-2.59Ma, base in Gelasian stage). Data source: [JRY rough estimate]

Plot of occurrence data:

Range-bar - range as quoted above, pink interval top occurs in, green interval base occurs in.
Triangles indicate an event for which a precise placement has been suggested
(NB There is no histogram as there are no occurrence records for the taxon in the Neptune database) Parent: Calciosolenia

In our article smaller forms (fig. 15-16) are also presented with spurs which is a consequence of warm and oligotroph water. Larger specimens without spurs are more characreristic for transition (of climate, current mixing, water exchanges, flooding, more nearshore influences, seasonality...)
