Original Description
slightly recurved. The wall is finely perforate with a foraminal density which is consistent for all specimens seen. Pustules may occur on both sides of the test, but in some specimens they may be confined to the central region of the umbilical side. The aperture is a large interiomarginal, umbilical-extraumbilical,semi-circular opening with a narrow lip, which is smooth in some specimens but pustulate in others.

Extra details from original publication
Globorotalia (T.) bononiensis is approximately the same size as Globorotalia (T.) praeoscitans, and it also has a large aperture, but Dondi's species appears to be biconvex, and the cameral inflation is more gradual. This is also true of Globorotalia (T.) inflata, which has the most globose chambers of the complex.
Globorotalia (T.) praeoscitans has been seen also at the Darling Slide locality, Jackson Bluff, Bed 9 Jackson Bluff Formation,Ecphora Faunizone), and in the Yorktown Formation at Wilson's Pit (TU 613 ). These beds are considered to be lowermost Pliocene to lower middle Pliocene (later part of Zone N. 18 to the later part of Zone N. 19 ).
Globorotalia (T.) praeoscitans is abundant in Yorktown beds at the Texas Gulf Sulphur Company mine near Aurora, North Carolina (TU 1022). This species and Globigerina bulloides are the predominant components of the planktonic assemblage.
