DESCRIPTION.
Type of wall: Normal perforate, spinose,
bulloides-type wall structure.
Test morphology: Test low trochospiral, lobulate
in outline, chambers globular; in spiral view 4 globular,
slightly embracing chambers in ultimate whorl,
increasing rapidly in size, sutures moderately depressed,
straight, last 4 chambers make up about three-fifths of
the test size; in umbilical view 31/2 globular, slightly
embracing chambers, increasing rapidly in size, sutures moderately depressed, straight, umbilicus small, open, enclosed by surrounding chambers, aperture umbilical, a low to high arch bordered by an imperforate rim; in edge view chambers globular in shape, slightly embracing.
Size: Maximum diameter of holotype 0.20 mm, thickness 0.11 mm. |

Van Eijden & Smit (1991):
Remarks. G. officinalis is the ancestor of Globigerinita glutinata (Egger, 1893), from which it differs by being less compact and lacking a bulla. Four-chambered G. angustiumbilicata Bolli, 1957a specimens are lower trochospiral.
Pearson et al. (2006):
DISTINGUISHING FEATURES.-
This small species is characterized by its globular, slightly embracing chambers with a moderately high-arched aperture bordered by a thickened imperforate rim, and its
bulloides-type wall texture. It is distinguished from
Globigerina praebulloides by its less gaping aperture
and slower rate of chamber enlargement.
DISCUSSION.-
Globigerina oflcinalis appears to be
the initial species in the evolution of the genus
Globigerina. The development of Globigerina
(bulloides-type) wall texture is observed in Subbotina
crociapertura Blow, which first appears in Zone P9.
Subbotina crociapertura, however, retains the basic large
subbotinid test morphology and has a distinctive
umbilical-extraumbilical hook-shaped aperture, which
suggests a morphologic trend away from the Globigerina
test morphology. The origin of the genus is most likely
derived hom a closely related subbotinid in which the
bulloides wall first evolved, Subbotina roesnaesensis n.
sp.
Globigerina officinalis is little used by workers
in the Eocene, which may-%e due to its small size and
lack of biostratigraphic value. Blow and Banner (1962)
erected two subspecies of Globigerina praebulloides
Blow, G. praebulloides leroyi and G. praebulloides
occlusa. Globigerinapraebulloides leroyi (their pl. 9,
figs. R-T) has a bulloides wall texture but G.
praebulloides occlusa has a cancellate wall texture,
which excludes it horn Globigerina. Globigerina praebulloides
Blow (described from the middle Miocene)
has a larger, more open aperture, and a more rapid
increase in chamber size than does G. praebulloides
leroyi. The latter is more similar to G. offiinalis in
having a smaller more umbilically restricted aperture
and in the slower rate of chamber size increase.
Subbotina (1953) stressed the variability in size of the
ultimate chamber of G. officinalis and illustrated this
range of variation in a suite of specimens (holotype and
originals). One of the originals (= paratype?; Subbotina,
1953, pl. 1 1, fig. 3a-c) shows a larger ultimate chamber
than the holotype (Subbotina, 1953, pl. 11, fig. 1 a-c).
G. praebulloides leroyi closely resembles Subbotina's
figure 2 a-c. Thus, there is a moderate range of variability
in the initial lineage of Globigerina and given current
information it is preferable to treat these morphotypes
as a single species, G. officinalis. Globigerina
praebulloides was derived from G. oflcinalis in the early
Oligocene and became the stem species for the radiation
of Globigerina in the Oligocene.
PHYLOGENETIC RELATIONSHIPS.-
Probably evolved from Subbotina roesnaesensis n. sp. in the middle Eocene. It gave rise to Globigerina praebulloides
in the early Oligocene.
GEOGRAPHIC DISTRIBUTION.-
Distributed in low to mid latitudes.
STABLE ISOTOPE PALEOBIOL0GY.-
Recorded by Pearson and others (2001) with relatively negative ò180
and positive ò13C suggesting a shallow water habitat. |
