The genus is strongly paraphyletic giving rise to Globigerinoides, Trilobatus (and thus Orbulina), Turborotalita, and Sphaeroidinella according to the phylogeny of Aze et al. 2011. [my interpretation - JRY 2018]
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]
In the description of this genus, Hofker (1976) and Olsson and others (2006) included only forms with 4-5 chambers in the last whorl. Spezzaferri and others (2015) amended the genus to include also 3-3½ chambered forms such as G. connecta. Olsson and others (2006) discussed the taxonomic connection and synonymy between Kennett and Srinivasan’s (1983) genus Zeaglobigerina and Globoturborotalita. Olsson and others (2006) also included in the genus Globoturborotalita anguliofficinalis, which is now placed in the new genus Ciperoella based on the wall texture and possession of 4 ½-5 chambers in the final whorl (Chapter 7, this volume). [Spezzaferri et al. 2018]
Hofker (1976) designated his genus Globoturborotalita, described from Holocene sediments, as characteristic of his new family Turborotalitidae. He recognized that this genus is spinose, a morphologic character that ultimately led to Turborotalitidae being placed in synonomy within Globigerinidae (Loeblich and Tappan, 1988). At the time Globoturborotalita was described, only one species was known, G. rubescens, the type species. One of the distinguishing features of Holocene G. rubescens is its pink to red pigmentation, a color that is not readily preserved in the fossil record. Hofker emphasized the coarsely cancellate wall texture and spines of this species. The cancellate spinose wall distinguishes Globoturborotalita from Globigerina.
Kennett and Srinivasan (1983) named Zeaglobigerina (type species Globigerina woodi Jenkins) but included rubescens within the genus, thus making their genus a junior synonym of Hofker’s, providing the phylogenetic linkage between woodi and rubescens is upheld.
Loeblich and Tappan (1988) gave a geologic range of Oligocene to Recent for Globoturborotalita. McGowran and Li (1993) placed Miocene planktonic foraminifera of southern Australia in five morphogroups based on wall texture (cancellate, cancellate-spinose, spinose, smooth-walled, and microperforate). Several species that they included in Globoturborotalita and that are common in the Oligocene, such as G. anguliofficinalis and G. gnaucki, first occur in the Eocene, thus extending the known range of this genus into the Eocene. Our own observations, reported here, indicate that the origin of Globoturborotalita was at the base of Zone E1 and was associated with the Paleocene-Eocene Thermal Maximum (PETM) and the carbon isotope excursion (CIE). A new species is described from this level, Globoturborotalita bassriverensis n. sp. Globoturborotalita in the Paleogene, as in the Neogene, is represented by small forms that are easily overlooked, but they can be recognized in well-preserved material.
Globoturborotalita probably evolved from Subbotina. The limited stable isotope data currently available for the genus suggests that unlike Subbotina, most taxa of Globoturborotalita were surface mixed layer dwelling forms.
