Coiled biserial

Small biserial test, often with a slightly twisted coiling axis. Intercameral sutures distinct, depressed, and often somewhat oblique. Aperture arched, rimmed by narrow lip, and generally infolded on one side of ultimate chamber.

Tests triserial, trochospiral, or nearly triserial in initial whorl becoming biserial. Chambers usually globular or subglobular, increasing gradually in size. Aperture usually a loop-shaped arch, often slightly infolded on one side, marked by a fine lip.

Test biserial, may become multiple or uniserial; chambers, globular to ovoid in shape; wall smooth or with parallel ridges; aperture, a low, symmetrical arch, usually at base of last chamber, may have accessory sutural apertures.

Taxonomic discussion:

Superfamily Guembelitrioidea includes three families that occur in the Oligocene, the biserial Chiloguembelinidae, the enrolled-biserial Cassigerinellidae, and the triserial Guembelitriidae. The superfamily level classification in this work follows the wall texture observations of Chapter 15 (this volume). This superfamily is characterized by the ototara-type wall which is microgranular, microperforate, bilamellar, smooth to finely pustulose or costate, and may have pore mounds on the test surface. All Paleogene Guembelitrioidea are thought to be descended from Guembelitria cretacea which was one of the few taxa to survive the Cretaceous / Paleogene mass extinction.[Fucek et al. 2018 Chiloguembelina]

The discovery by D’Haenens and others (2012) of endospikes in Chiloguembelina, virtually identical to those described in Cassigerinella by Pearson and Wade (2009), is good evidence that the two genera belong to the same phylogenetic group, and that the wall texture of Cassigerinella is a subtype of the ototara-type wall. The ototara-type wall helps define a distinct higher taxonomic group. For that reason we assign the Cassigerinellidae to Superfamily Guembelitrioidea. [Pearson et al. 2018 Cassigerinella]

Catalog entries: Guembelitriinae

Distinguishing features:
Parent taxon (pf_cenozoic): This is a polyphyletic grouping including all Cenozoic planktonic foraminifera
This taxon: Biserial, enrolled biserial and triserial taxa. Wall microperforate.

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.
