Citation: Globigerinoides bulloideus (Crescenti 1966)Taxonomic rank: speciesBasionym: Globigerinoides bulloideus Crescenti 1966Taxonomic discussion: Not in list of Aze et al. (2011) but the species is used by Kennett & Srinivasan (1983), Bolli & Saunders (1985) and Lam & Leckie (2020). Spezzaferri et al. 2015 cite the species as being included intheir definition of Globigerinoides but did not comment further on it. If it did evolve from Globigerina bulloides then it should presumably be removed from Globigerinoides. [editor's comment - JRY 2018]
Distinguishing features: Parent taxon (Globigerinoides): Supplementary apertures, with ruber/sacculifer-type spinose wall texture This taxon: Like G. bulloides but with supplementary apertures on the spiral side
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
Morphology: Test low to medium-high-trochospiral, wider than high; chambers spherical to subspherical, the four chambers of the last whorl increasing rapidly in size; sutures on spiral and umbilical side gently curved and depressed; surface hispid with spine bases and slightly pitted on earlier chambers; umbilicus wide, deep; primary aperture interiomarginal, umbilical, large, semicircular arch bordered by a distinct rim. Last few chambers show a single supplementary aperture opposite the primary one. [Kennett & Srinivasan 1983]

Biogeography and Palaeobiology
Phylogenetic relationsIn gross morphology, this species closely resembles Globigerina (Gg.) bulloides, from which it evolved by developing supplementary apertures on spiral side. [Kennett & Srinivasan 1983]
Biostratigraphic distribution
Geological Range: Last occurrence (top): within N19 zone (4.37-5.20Ma, top in Zanclean stage). Data source: Kennett & Srinivasan (1983) First occurrence (base): within N17b zone (5.72-6.60Ma, base in Messinian stage). Data source: Kennett & Srinivasan (1983)
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.
Grey shading between taxa indicates intergrading species within an anagenetic lineage (data from
Lamyman et al. 2026).
(NB There is no histogram as there are no occurrence records for the taxon in the Neptune database) Parent: Globigerinoides
