Daughter taxa (time control age-window is: 0-800Ma)
Extant and Neogene species
Globigerina bulloides
Usually 4 chambers in final whorl; Aperture a high symmetrical arch.
Globigerina falconensis
4 chambers in final whorl; Umbilicus small but deep; Aperture an elongate narrow arch with prominent lip
Globigerina umbilicata
5-6 chambers in final whorl; often with kummerform final chamber. Umbilicus very large, deep. Aperture large, umbilical, with thin lip.
Paleogene species
Globigerina archaeobulloides
Like G. officinalis but with lobed peripheral outline, and fully developed bulloides-type wall
Globigerina officinalis
Small, chambers globular, slightly embracing; aperture moderately high-arched with a thickened rim; bulloides-type wall texture.
Globigerina sp.
Specimens which cannot be assigned to established species

Taxonomy

Citation: Globigerina d’Orbigny, 1826
Rank: Genus
Type species: Globigerina bulloides d’Orbigny, 1826
Taxonomic discussion: The most iconic and the earliest described genus of planktonic foraminifera, typified by the well-established Globigerina bulloides d’Orbigny, 1826. Originally used widely for almost all species considered planktonic, now limited to a lineage of spinose planktonic foraminifera with a finely spinose wall and single umbilical aperture (Spezzaferri et al., 2018a) [Brummer & Kucera 2022]

Catalog entries: Globigerina

Distinguishing features:
Parent taxon (Globigerinidae): Wall spinose, usually with 3½-6 globular chambers in final whorl, trochospiral or planispiral
This taxon: Low trochospirally enrolled, globose test; 3-5, globular chambers in final whorl. Aperture interiomarginal, umbilical, a high arch bordered by a thin rim-like lip or thick imperforate lip. Wall spinose; spines supported by spine collars which coalesce to form ridges.

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.

Biogeography and Palaeobiology


Phylogenetic relations: The origin of Globigerina is uncertain. In wall texture it appears closest to Subbotina roesnaesensis n. sp., which has a ruber-type cancellate wall texture with spine collars (first observed in its ancestral species Subbotina triangularis in Zone P4).
[Olsson et al. 2006]
