Taxonomic discussion:

Ciperoella anguliofficinalis is a common species in the Oligocene, evolving in the upper Eocene. It was described as a species of Globigerina. Olsson and others (2006) placed it in the genus Globoturborotalita. SEM study of the wall texture of this species shows a Neogloboquadrina-type wall characteristic of the new genus Ciperoella. The angular appearance of anguliofficinalis chambers in the holotype (Pl. 7.1, Figs. 1-2) is likely due to gametogenetic build-up. In spiral view the outline of rounded chambers is more clearly visible. Ciperoella anguliofficinalis becomes more common in the Oligocene. In fact Pearson and Chaisson (1997:48) remark that “the base of “G.” anguliofficinalis-like morphologies coincides with the base of “G.” angulisuturalis and they co-occur for much of the stratigraphic range of that form”.  [Olsson et al. 2018]

Rögl’s (1969) Paratethys species Globigerina ciperoensis ottnangiensis, described from the lower Miocene of Austria where it is a common and important stratigraphic marker, appears to be a junior synonym of C. anguliofficinalis (holotype Pl. 7.1, Fig. 13). Both anguliofficinalis and ottnangiensis were published in 1969, however, Blow presented his work at the 1967 foraminifera conference in Geneva giving anguliofficinalis priority.  [Olsson et al. 2018]

The upper part of the stratigraphic range of both C. anguliofficinalis, as well as the other ciperoensis-group taxa is complicated by Rögl’s ottnangiensis. Based on comparisons of the holotype (reproduced here on Pl. 7.1, Fig. 13) and paratype images (Rögl, 1969), we cannot consistently distinguish ottnangiensis from C. anguliofficinalis. In fact, Rögl (1969, 1994) describes and illustrates a high degree of variability among forms assigned to ottnangiensis that includes features of anguliofficinalis, ciperoensis and angulisuturalis.  [Olsson et al. 2018]

Ciperoella anguliofficinalis is present in the late Rupelian and early Chattian in the southern North Sea Basin (Hooyberghs and De Meuter, 1972; Hooyberghs and others, 1992). Among the examples described from the Belgian Boom Clay, several specimens described as ‘G. angustiumbilicata Bolli’, but lacking a microperforate wall (that we now know this taxon to possess), can be assigned to Ciperoella anguliofficinalis (e.g., Hooyberghs and others, 1992). Pearson and Chaisson (1997) record “G.” anguliofficinalis occurring throughout the range of ciperoensis and angulisuturalis.  [Olsson et al. 2018]

Spezzaferri (1994) records a common highest occurrence for ciperoensis and anguliofficinalis in the Indian Ocean, Gulf of Mexico and Caribbean, equatorial and North Atlantic Ocean that correlates to the uppermost part of lower Miocene Zone N4b/N5 (= end M1). In its type region, Rögl (1994) and Cicha and others (1998) show ottnangiensis to range above the highest occurrence of C. ciperoensis s.s. up to the lower/middle Miocene boundary (= Zone M5 = end of the Burdigalian stage = Eggenburgian-Karpathian central Paratethys stages). Spezzaferri (1994) records a similar stratigraphic range for forms she records and illustrates as “G.” ottnangiensis and “G.” aff. ottnangiensis in a number of Atlantic, Indian, and Pacific Ocean deep sea drill sites. Having here synonymized ottnangiensis under anguliofficinalis we extend the range of anguliofficinalis to Zone M5. Further investigation of Miocene sequences (which is beyond the scope of this study) is necessary to further test the morphological and stratigraphic limits of the ciperoensis-group in the Paratethys compared to open ocean. [Olsson et al. 2018]

Type images:

Distinguishing features:
Parent taxon (Ciperoella): Like Globoturborotalita, but with distinctive reticulate wall, and 4½-5 chambers in final whorl
This taxon: Like C. ciperoensis but less lobulate peripheral outline, more compact form and a greater rate of chamber size increase

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.


Moderately low trochospiral, globular, lobulate in outline, chambers globular; in spiral view 5 slightly embracing chambers in final whorl, increasing moderately in size, sutures depressed, straight; in umbilical view 5 slightly embracing chambers, increasing moderately in size, sutures depressed, straight, umbilicus large, open, enclosed by surrounding chambers, aperture umbilical, a rounded arch, bordered by a thin rim; in edge view chambers globular, slightly embracing, initial whorl slightly elevated. [Olsson et al. 2018]

Wall type:
Normal perforate, spinose, Neogloboquadrina-type wall texture. Pore concentrations range from around 25-60 pores/50 μm2 test surface area and pore diameters from around 0.9-2.5 μm [Olsson et al. 2018]

Maximum diameter 0.21-0.30 mm, minimum diameter 0.18-0.21 mm, maximum width 0.17 mm. [Olsson et al. 2018]

Biogeography and Palaeobiology

Geographic distribution

Cosmopolitan from high to low latitudes, including the North Sea and Paratethys regions. [Olsson et al. 2018]

Isotope paleobiology
Douglas and Savin (1978) recorded moderately negative δ18O for this species indicating a mixed-layer habitat. [Olsson et al. 2018]

Phylogenetic relations
Evolved from Ciperoella gnaucki in the upper Eocene (Zone E15). Gave rise to C. angulisuturalis and C. ciperoensis. [Olsson et al. 2018]

Most likely ancestor: Globoturborotalita gnaucki - at confidence level 4 (out of 5). Data source: Olsson et al. 2006, f5.1.

Biostratigraphic distribution

Geological Range:
Notes: Zone E15? (Olsson and others, 2006) to lower middle Miocene Zone M5 (Rögl, 1994; Spezzaferri, 1994). The upper stratigraphic limit includes the range of Globigerina ottnangiensis and “Globigerina” aff. ottnangiensis described from the Paratethys region (Rögl, 1969) and elsewhere (Spezzaferri, 1994) and here synonymized under Ciperoella anguliofficinalis. [Olsson et al. 2018]
Last occurrence (top): within M5 zone (15.1-16.38Ma, top in Langhian stage). Data source: Olsson et al. 2018
First occurrence (base): near top of E15 zone (90% up, 34.8Ma, in Priabonian stage). Data source: Eocene Atlas
