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

Daughter taxa: (blue => in age window 0-300Ma)
Like G. woodi but with very large aperture
Like G. woodi but subquadrate test and aperture placed directly opposite the suture line
Like G. woodi but compact test and more highly arched aperture

decoraperta->rubescens->tenella lineage
Like G. rubescens but with a small, supplementary aperture.
Like G. decoraperta but very small and with small circular aperture.
Like G. woodi but higher-spired test
bolli->kennetti lineage
Like Gs. bolli but only 3 to 3½ chambers in final whorl (vs. 4), less-embracing chambers, and more subquadrate outline
Small, compact,  aperture almost circular. Supplementary sutural aperture on spiral side
druryi->nepenthes lineage
Like G. druryi but with protruding thumb-shaped final chamber
Small, compact test, with coarse-pitted surface, and small, rimmed, aperture
Specimens which cannot be assigned to established species


Citation: Globoturborotalita Hofker 1976
Rank: Genus
Type species: Globigerina rubescens
Taxonomic discussion: Kennett & Srinivasan (1983) proposed a new subgenus Zeaglobigerina for Neogene Globigerina species with a cancellate wall. This concept is now standard but the name Globoturborotalita Hofker 1976 is used as it is a senior synonym.
The genus is strongly paraphyletic giving rise to Globigerinioides, Trilobatus (and thus Orbulina), Turborotalita, and Sphaeroidinella according to the phylogeny of Aze et al. 2011.

Catalog entries: Globigerina (Zeaglobigerina); Globoturborotalita;

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

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.


Test morphology: Includes species characterized by a cancellate surface with regular subhexagonal pore pits with pores at the centers (Pi. 4, Fig. 2). Thus, the surface of Globoturborotalita appears distinctly cancellate in contrast to the hispid appearance of Globigerina. Although the surface ultrastructure of Globoturborotalita is similar to Globigerinoides saccullfer, which is spinose during life, no indication of spines or spine bases was observed in Globoturborotalita species. We consider that the genus Globoturborotalita is the ancestor of Globigerinoides sacculifer, which evolved via Globoturborotalita connecta and Globigerinoides triloba. [Kennett & Srinivasan 1983 - but with references to Globigerina (Zeaglobigerina) changed to Globoturborotalita]
