Taxonomic discussion:

This is an easily identified species and its first occurrence is a marker for the lower Oligocene Zone O4 (Wade and others, 2011). We note that C. angulisuturalis is missing from published species lists for the boreal North Sea (Hooybergh and De Meuter, 1972; Hooyberghs and others, 1992), whereas the ancestor C. anguliofficinalis and descendant C. ciperoensis respectively are recorded and illustrated (Rögl, 1969). This suggests that C. angulisuturalis has a more tropical affinity than other members of the genus and may explain the observed diachroneity of the last occurrence (see below). Blow (1969) regarded extreme versions with overly deepened sutures (Blow, 1969; pl. 11, fig. 9; pl. 12, figs. 1 and 2) from Zone N3/P22 (= O6/O7) Sicily as “phylogenetically advanced”. [Olsson et al. 2018]

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 smaller; chambers squared off / wedge-shaped; sutures distinctly depressed; large umbilical aperture.

Description

Moderately low trochospiral, globular, lobulate in outline, chambers globular; in spiral view 5 globular, slightly embracing chambers in ultimate whorl, increasing moderately in size, chambers squared off at sutures, sutures distinctly depressed, straight; in umbilical view 5 globular, slightly embracing chambers, increasing moderately in size, chambers squared off at sutures, sutures distinctly depressed forming steep U-shaped walls between chambers, 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 of chambers slightly elevated. [Olsson et al. 2018]

Normal perforate, spinose, Neogloboquadrina-type wall. Pore concentrations range from around 25-60 pores/50 μm2 test surface area and pore diameters from around 0.9-2.5 μm.

Maximum diameter of holotype 0.18 mm, minimum diameter 0.16 mm, thickness 0.11 mm. [Olsson et al. 2018]

Biogeography and Palaeobiology

Widespread in low to mid-latitudes. Rare or absent in high productivity areas. [Olsson et al. 2018]

Poore and Matthews (1984) and Shackleton and others (1984) record C. angulisuturalis as having isotopic ratios indicative of shallow, mixed-layer habitat. [Olsson et al. 2018]

Evolved from Ciperoella anguliofficinalis in the lower Oligocene. See the Ciperoella genus introduction for a summary on previous views on the evolutionary pathway. It did not leave any descendants. [Olsson et al. 2018]

Biostratigraphic distribution

Geological Range:
Notes: Zone O4 to M2. The FAD of C. angulisuturalis defines the base of Zone O4 (29.4 Ma), and the LAD is within Zone M2 (21.6 Ma) (Berggren and others, 1995; Wade and others, 2011). An earlier LAD in Subzone M1b is recorded in the Indian Ocean and Caribbean by Spezzaferri (1994). Pearson and Chaisson (1997:40) remarked that the datum is difficult to place in the equatorial Atlantic Ocean because of “a combination of abundance fluctuations of “G.” angulisuturalis in the higher part of its range and its susceptibility to dissolution”. [Olsson et al. 2018]
Last occurrence (top): within M2 zone (19.30-21.12Ma, top in Burdigalian stage). Data source: Olsson et al. 2018
First occurrence (base): within O4 zone (28.09-29.18Ma, base in Rupelian stage). Data source: Olsson et al. 2018
