Genus Globigerinita Brönnimann, 1951


Original Description
Test distinctly trochoidal; chambers subglobular, increasing gradually in size, non-enveloping in the adult. Umbilical portion covered with single, irregularly shaped, frequently inflated, supplementary chamber. Aperture multiple in the adult, consisting of small semicircular openings along the sutures of supplementary chamber. These openings are arched with minute lips. Apertures of chambers formed prior to the supplementary chamber are single, large, broad, semicircular openings with minute lips. Wall variable in thickness, finely perforate.

Extra details from original publication
Remarks: The monotypic genus Globigerinita is characterized by the distinctly trochoidal test, the single irregularly shaped supplementary chamber, the large semicircular apertures connecting the Globigerina chamber; and the multiple aperture along the suture of the supplementary chamber. Its essential difference from the morphologically similar genus Globigerinatella are the non-enveloping adult Globigerina chamhers and the single apertures connecting the late Globigerina chambers. The ancester of Globigerinita apparently is a small trochoidal Globigerina with single, large aperture similar to that of the early ontogenetic stage of Globigerinatella (Globigerina stage with single aperture).

Occurrence:Lower Miocene, possibly also upper Oligocene of Trinidad, B. W. I.
