Globigerina bulloides

Classification: pf_neogene -> Globigerinidae -> Globigerina -> Globigerina bulloides
Sister taxa: G. bulloides, G. falconensis, G. umbilicata, G. sp.,

Taxonomy

Citation: Globigerina bulloides d’Orbigny, 1826
Rank: species
Basionym: Globigerina bulloides
Variants:

"The test of Gg. (Gg.) bulloides shows considerable variation in the number and shape of chambers in the final whorl and size of the aperture. This has resulted in the erection of a number of species, ...They are all regarded here as phenotypic variants of Gg. (Gg.) bulloides." [Kennett & Srinivasan 1983]

  • Globigerina quadrilatera Galloway & Wissler 1927 (Pleistocene California)
  • Globigerina bermudezi Seiglie, 1963 (Late Pleistocene to Recent Cariaco Basin and Caribbean)
  • Globigerina megastoma cariacoensis Rögl and Bolli, 1973 (Late Pleistocene to Recent, Tropical Atlantic)
  • Globigerina riveroae Bolli and Bermudez, 1965 (Pliocene, Venezuela). 

New SEM images of the holotype of Globigerina riveroae Bolli and Bermudez, 1965 indiacte a cancellate wall, and therefore this form has been moved out of synonymy of G. bulloides (Bridget Wade, November 2017).

Short diagnosis: No apertural lip

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.

Description


Diagnostic characters: Low trochospiral, chambers spherical to subspherical

Aperture: : Umbilical high symmetrical arch [Aze 2011, based on Kennett & Srinivasan 1983]

Coiling direction (in extant population): mixed with bias to sinistral


Wall type: Spinose; Hispid [Aze 2011]

Test morphology: Test low-trochospiral, usually four chambers in the final whorl; chambers spher- ical to subspherical, increasing regularly in size as added; sutures distinctly depressed; surface uniformly and densely perforate with simple spines. Aperture umbilical, a high symmetrical arch. [Kennett & Srinivasan 1983]

Size: >150µm

Biogeography and Palaeobiology


Geographic distribution: Distribution is centered in temperate areas. Relative abundances decrease toward the tropics. The species is rare in equatorial areas. [Kennett & Srinivasan 1983]

Isotope paleobiology: Aze et al. 2011 ecogroup 2 - Open ocean mixed-layer tropical/subtropical, without symbionts. Based on ∂13C lighter than species with symbionts; also with relatively light ∂18O Cited sources (Aze et al. 2011 appendix S3): Vergnaud-Grazzini (1976); Durazzi (1981).

Phylogenetic relations: Molecular Genotypes recognised (data from PFR2 database, June 2017). References: Darling et al. 2000; Darling et al. 2003; Darling & Wade 2008; Morard et al. 2013; Ujiié & Lipps 2009; Seears et al. 2012; Stewart 2001.
