Taxonomic discussion:

This is a well known species in the Oligocene and is the type species for the new genus Ciperoella. ‘Giant’ “Globigerina ciperoensis” recorded by Ujetz and Wernli (1994) from Zone P20 (= O2) of the Haute-Savoie in France appear to be conspecific with Globigerinella wagneri (Chapter 6, this volume) described from an equivalent level in the Central Paratethys region (Rögl, 1994).

Reuss (1850) described Globigerina concinna from the Tertiary (probably Tortonian) of Austria, for large forms possessing 5 globular chambers, with a wide umbilical aperture. This form was recognized by Nuttall (1932) from the Alazan shales of Mexico, and Franklin (1944) from the Oligocene, Carapita Formation, of Venezuela. Cushman and Stainforth (1945) recognized cf. concinna from the Oligocene, Cipero Formation of Trinidad and considered it to be a useful stratigraphic marker. Bolli (1954) investigated the species concept but found that the type material was lost. He concluded that the lower Oligocene specimens recognized by Nuttall (1932), Franklin (1944) and Cushman and Stainforth (1945) were smaller and not directly related to G. concinna and thus described Globigerina ciperoensis to incorporate these forms. The type specimen is that of Cushman and Stainforth (1945), pl. 13, figs. 1a-1b. Note, Bolli and Saunders (1985) indicate that the holotype is from the Globorotalia opima opima Zone, but this is not consistent with Bolli (1954) which indicates the Globigerina ciperoensis Zone. [Olsson et al. 2018]

Type images:

Distinguishing features: Test low trochospiral, globular, lobulate, umbilicus open; 5 chambers in final whorl; aperture umbilical;

NB These concise distinguishing features statements are used in the tables of daughter-taxa to act as quick summaries of the differences between e.g. species of one genus.
They are being edited as the site is developed and comments on them are especially welcome.


Diagnostic characters:

The species is distinguished from C. anguliofficinalis and C. angulisuturalis by the typically larger size, and open umbilicus. Its sutures are usually narrow and shallow but can be somewhat incised as in the holotype specimen, this can lead to confusion with C. angulisuturalis. Ciperoella fariasi Bermúdez is morphologically similar but is larger, more globular and has a more elevated initial spire than C. ciperoensis. [Olsson et al. 2018]

Wall type: Normal perforate, spinose, Neogloboquadrina-type wall structure. Pore concentrations average 32 pores/50 μm2 test surface area and pore diameters from around 0.9-2.5 μm.

Test morphology: Moderately low trochospiral, globular, lobulate in outline, chambers globular; in spiral view 5 globular, slightly embracing chambers in ultimate whorl, increasing slowly in size, ultimate chamber may be smaller than the penultimate chamber, sutures depressed, straight; in umbilical view 5 globular, slightly embracing chambers, increasing slowly in size, ultimate chamber often smaller than the penultimate chamber, sutures depressed, straight, umbilicus large, open, enclosed by surrounding chambers, aperture umbilical, a rounded arch, bordered by a thin thickened rim; in edge view chambers globular, slightly embracing, initial whorl slightly to moderately elevated. [Olsson et al. 2018]

Size: Maximum diameter of holotype 0.29 mm, minimum diameter 0.26 mm, thickness 0.18 mm. [Olsson et al. 2018]

Biogeography and Palaeobiology

Geographic distribution: Occurs in low to mid-latitudes including the North Sea (Hooyberghs and De Meuter, 1972, Hooyberghs and others, 1992) and Paratethys region (Rögl, 1994). [Olsson et al. 2018]

Isotope paleobiology: Poore and Matthews (1984) consistently record low δ18O and high δ13C in C. ciperoensis indicative of a symbiotic ecology within the surface mixed-layer. [Olsson et al. 2018]

Phylogenetic relations: Evolved from C. anguliofficinalis in the mid-Oligocene and gave rise to C. fariasi. [Olsson et al. 2018]

Most likely ancestor: Ciperoella anguliofficinalis - at confidence level 4 (out of 5). Data source: [Olsson et al. 2018].
Likely descendants: Ciperoella fariasi;

Biostratigraphic distribution

Geological Range:
Notes: Zone O3 to Subzone M1a. The lowest occurrence is not well constrained. Most records are from the upper Oligocene, but Blow and Banner (1962) record C. ciperoensis in Zone O3 in Tanzania. The top of C. ciperoensis is used as a secondary marker within Subzone M1a (23.68 Ma, Pearson and Chaisson, 1997; Wade and others, 2011). [Olsson et al. 2018]
Last occurrence (top): within M1a subzone (22.44-22.96Ma, top in Aquitanian stage). Data source: Olsson et al. 2018
First occurrence (base): within O3 zone (29.18-30.28Ma, base in Rupelian stage). Data source: Olsson et al. 2018
