Globigerina

Classification: pf_cenozoic -> Globigerinidae -> Globigerina
Sister taxa: Beella, Globigerina, Globigerinella, Protentella, Quiltyella ⟩⟨ Ciperoella, Globigerinoides, Globigerinoidesella, Globoturborotalita, Orbulina, Praeorbulina, Sphaeroidinella, Sphaeroidinellopsis, Trilobatus, Turborotalita ⟩⟨ Dentoglobigerina, Globoquadrina ⟩⟨ Catapsydrax, Clavatorella, Paragloborotalia, Protentelloides ⟩⟨ Eoglobigerina, Globigerinatheka, Globorotaloides, Guembelitrioides, Orbulinoides, Parasubbotina, Pseudoglobigerinella, Subbotina

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 neofalconensis Globigerina neofalconensis can be distinguished from its ancestor G. falconensis by its more lobate profile,more loosely coiled test and the wider umbilicus.
			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

taxonomic 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.

Description

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]

Most likely ancestor: Subbotina - at confidence level 0 (out of 5). Data source: .

Biostratigraphic distribution

Geological Range:
Notes: Middle Eocene (E10) to Recent. [Olsson et al. 2006]
Last occurrence (top): Extant. Data source: Total of ranges of the species in this database
First occurrence (base): within E10 zone (41.89-43.23Ma, base in Lutetian stage). Data source: Total of ranges of species in this database

Plot of occurrence data:

Range-bar - range as quoted above, pink interval top occurs in, green interval base occurs in.
Triangles indicate an event for which a precise placement has been suggested
Neptune data: This is a higher taxon page so Neptune data is not plotted. See also: customisable plot Parent: Globigerinidae
