NB TAXA WHICH ORIGINATE IN THE OLIGOCENE ARE NOT INCLUDED YET
Classification: pf_neogene -> Globigerinidae
Sister taxa: Bolivinidae, Candeinidae, Globigerinidae, Globorotalidae, Guembelitriidae , Hastigerinidae, hidden,

Distinguishing features: spinose, visible pores

Daughter taxa: Genera divided into three major groups following phylogeny of Aze et al. 2011 (blue => in age window 0-300Ma) Granddaughter taxa
Globigerina group
Digitate chambers:

Trochospiral test with a single, large, open umbilical aperture. Spinose, non-cancellate, wall.

Trochoid test becoming nearly planispiral, globular to ovate chambers, umbilical aperture, and fine spines covering the test

low trochospiral to planispral, adult chambers radially elongate. Wall reticulate with deep pore pits.

Globigerinoides group
Supplementary apertures, with bulloides-type spinose wall texture

Supplementary apertures, cancellate wall & elongate extensions to final chamber.

Trochospiral test with a single, large, open umbilical aperture. Cancellate wall.

Spherical terminal chamber:

Terminal chamber partially enveloping previous chambers

Like Sphaeroidinellopsis but with supplementary apertures

trochospiral test, globular chambers, and a heavy, smooth, shiny cortex

Supplementary apertures and cancellate wall.

Minute, with bullate extension of the final chamber, smooth microperforate wall, large pores and short conical spines concentrated along the periphery

Paragloborotalia group
Small umbilical bulla with a few accessory apertures

low trochospiral test, later chanbers radially elongate and club shaped.

Low trochospiral, globular to subglobular chambers, umbilical-extraumbilical aperture with rim

incertae sedis
Spine bases at chamber tips:

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.
