... spiral chambers, must be removed from the rotaliids. The subfamily represents a Tethyan group of Late Cretaceous, spiral, benthic foraminifera that tended to become orbitoidiform in parallel with a Caribbean group, consisting of Sulcoperculina , Vaughanina , Pseudorbitoides and cohorts (Pseudorbitoidinae...

...). They occur in prominent limestone units that are regarded as ranging in age from Campanian to Early Maastrichtian on the basis of nannofossils and accompanying rudist assemblages. Cretaceous pseudorbitoid, orbitoid, and orbitocyclinid foraminifera are useful in interpreting fluctuations of the depositional...

..., Douvillé identified a small orbitoidid in the Caribbean Late Cretaceous said to be different from Pseudorbitoides trechmanni, which he had formerly described from material collected in Jamaica. The small orbitoidids studied by Douvillé had been collected by Böse and Staub from a section the Tampico...

..., but their age cannot be determined in the San Jose section because of the absence of planktic foraminifera as a result of the shallow-water platform environment. Abundant rudists (mostly radiolitids and rare hippuritids), milliolids and larger foraminifera indicate a Maastrichtian age (e.g. Pseudorbitoides...

... (1993) suggested that the orthophragminids might have descended from a Cretaceous pseudorbitoid ancestor, such as the American Vaughanina (Fig. 5.1). This appears to be the most plausible proposal for both the discocyclinines and the orbitoclypeines, considering that we have shown above...
