Globigerina 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.
Globoquadrina Trochospiral with quadrate to subquadrate profile; aperture in interiomarginal / umbilical-extraumbilical, one or more tooth-like projections extending into the umbilicus.
Paragloborotalia Very low trochospiral test with low-arched umbilical-extraumbilical aperture with a thick lip; 4-5 chambers in the ultimate whorl, and a coarsely cancellate, sacculifer-type wall.
Eoglobigerina Low, trochospiral test, 4-6½ globular chambers in final whorl; umbilicus small and open to the apertures of surrounding chambers.
Wall cancellate and spinose wall with spine holes along the ridges.
Parasubbotina Very low trochospiral test, chambers increasing rapidly in size; aperture high-arched umbilical-extraumbilical aperture. At most 5 chambers in final whorl.
Subbotina Low trochospiral, tripartite test, with 3-4 rapidly inflating, globular chambers in final whorl.
Umbilicus nearly closed by tight coiling.
Wall cancellate with spines at nodes of the ridges, +/- spine collars.
The family Globoquadrinidae was erected by Blow (1979) to include Globoquadrina and Dentoglobigerina plus other genera (Globorotaloides and Globigerinita, which is now regarded as a microperforate genus) that are no longer believed to be closely related. The critical feature that linked these groups, according to Blow, was a shift in aperture from a more extraumbilical to intraumbilical position during ontogeny, and significant differences in wall textures were not taken into account. Olsson and others (2006a) retained the family but in a very different sense, uniting two genera (Globoquadrina and Dentoglobigerina) that were believed, at that time to be nonspinose, and hence were excluded from the spinose Globigerinidae. These genera are now regarded as spinose or descended from a closely related spinose form (see Pearson and Wade, 2015, and Chapter 11, this volume) hence they are now included in family Globigerinidae. [Coxall & Spezzaferri 2018]
A great variety of species and genera with diverse morphologies evolved from the simple trochospiral globigerine forms in the Paleocene. Only the genera Eoglobigerina, Parasubbotina, and Subbotina are represented in the Paleocene. [Olsson et al. 1999]
Distinguishing features: Parent taxon (pf_cenozoic): This is a polyphyletic grouping including all Cenozoic planktonic foraminifera This taxon: Wall spinose, usually with 3½-6 globular chambers in final whorl, trochospiral or planispiral
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.
Geological Range: Last occurrence (top): Extant. Data source: Total of ranges of the species in this database First occurrence (base): within P0 zone (66.00-66.04Ma, base in Danian 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. For the customisable plot option go to a genus page Parent: pf_cenozoic

I noticed an imprecision in the description of the genus Globigerinoides. The wall texture must be ruber type or ruber/sacculifer type, instead of bulloides type.
Thank you.

i somehow missed your comment until just now but i have corrected the description now.
