Citation: Globigerinoides Cushman 1927
Rank: genus
Type species: Globigerina rubra d'Orbigny 1839
Taxonomic discussion: The genus Globigerinoides was used by Kennett & Srinivasan (1983) and many other workers for all Neogene  Globigerina-type species with supplementary apertures, but it was long suspected that this was a polyphyletic group. Spezzaferri et al. (2015) conclusively proved this polyphyly using both stratophentic and molecular genetic data and so divided the species into two groups - Trilobatus and Globigerinoides, as used here. They have separate origins and different wall structures.

Short diagnosis: Supplementary apertures, with bulloides-type spinose wall texture

NB The short diagnoses are used in the tables of daughter-taxa to act as quick summaries of the differences between e.g. species of one genus. They have initially been copied from the diagnostic characters/distinguishing features sections of the Eocene and Paleocene Atlases, they will be edited as the site is developed.


Wall type: The wall texture is cancellate, irregular honeycomb, with spines irregularly distributed, it may be ruber-type or sacculifer/ruber-type sensu Hemleben et al. 1989. [Spezzaferri et al. 2015]

Test morphology:

Test low to high trochospiral, globigeriniform and generally evolute, consisting of 2½ to 3 whorls. The peripheral margin is rounded, the test outline is from subcircular to slightly ovate or subtriangular to subrectangular and lobate. Chambers are generally globular to ovate, but may become radially compressed and asymmetrical, three to four in the last whorl increasing gradually in size as added. The primary aperture is umbilical and placed in a generally wide and open umbilical area; supplementary apertures are present on the spiral side, they may be one or more and are placed at the intersection of the spiral and radial sutures. Thin lips may be present on the primary and supplementary apertures. [Spezzaferri et al. 2015]

Biogeography and Palaeobiology

Biostratigraphic distribution

Geological Range:
Notes: The genus first appears at the Oligocene-Miocene transition, and in particular at the base of Subzone M1a and is still present in the modern oceans. [Spezzaferri et al. 2015]
Last occurrence (top): Extant Data source: Total of range of species in this database
First occurrence (base): within Chattian Stage (23.03-28.09Ma, base in Chattian stage). Data source: Total of range of species in this database
