Species Subbotina corpulenta Subbotina 1953

Diagnosis / Definition:

Pearson et al. (2006):
DESCRIPTION. Type of wall: Cancellate, normal perforate, spinose. Test morphology: Test moderately high trochospiral, lobulate in outline, chambers globular; in spiral view 4-4 1/2 globular chambers in ultimate whorl, increasing moderately in size, sutures moderately depressed, straight to slightly curved; in umbilical view 4-4 1/2 globular chambers, increasing moderately in size, often with a reduced ultimate chamber cantilevered over the umbilicus, sometimes centered and resembling a bulla, sutures moderately depressed, straight to slightly curved, umbilicus moderate in size, enclosed by surrounding chambers and often partly to entirely covered by the ultimate chamber; aperture umbilical, generally without a lip; in edge view test with a moderately elevated initial whorl, chambers globular in shape, aperture generally not visible. Size: Maximum diameter of holotype 0.57 mm, thickness 0.38 mm.

Discussion / Comments:

Pearson et al. (2006):
DISTINGUISHING FEATURES.- The species is characterized by its generally large adult size, moderately elevated initial spire, lobulate test, globular chambers and the cantilevered ultimate chamber directed over the umbilicus. DISCUSSION.- Subbotina corpulenta belongs to the group of large subbotinids which includes S. eocaena and S. hagni. It differs from S. hagni in the arrangement of the ultimate chamber, which is cantilevered over the umbilicus in varying degrees. Although this arrangement does not occur in all specimens, it characteristically occurs in a population of the species. Subbotina eocaena is more tightly coiled and has 3 1/2 chambers in the ultimate whorl. Globigerina cryptomphala Glaessner may be a senior synonym but Glaessner's specimens are lost. Subbotina (1953) apparently did not consider his species as representing her new species S. corpulenta and placed cryptomphala in synonomy with Globigerina bulloides d'orbigny. However, Toumarkine and Luterbacher (1985) recognized Glaessner's species, and considered it separate from cryptomphala. We place all these morphotypes in S. corpulenta. As noted by many workers, the peak abundance of large subbotinids occurs in the middle to upper Eocene. They are less abundant in the uppermost Eocene, where they are replaced by various species of Dentoglobigerina. PHYLOGENETIC RELATIONSHIPS.- Subbotina corplenta belongs to a group of closely related Eocene large-sized subbotinids, which includes S. eocaena and S. hagni. It is closely related to S. hugni, from which it evolved, by development of an elevated initial spire, and an umbilically cantilevered ultimate chamber. GEOGRAPHIC DISTRIBUTION.- Global in low to mid latitudes. STABLE ISOTOPE PALEOBIOL0GY.- Poore and Matthews (1984) and Boersma and others (1987) recorded this species (as Globigerina pera) as having the most positive ò18O of any planktonic species in the lower Oligocene, indicating a deep water habitat.
