| Diagnosis / Definition: |
Pearson et al. (2006):
DESCRIPTION.
Type of wall: Coarsely muricate, often with
relatively smooth umbilical face to final chamber, normal
perforate, nonspinose.
Test morphology: Robust, compact, subquadrate,
strongly and bluntly muricate test; 3-4 triangular-shaped
chambers in last whorl); chambers arranged at distinct
right angles to each other and usually separated by
distinct and incised sutures (particularly between preantepenultimate
and antepenultimate chambers) on the
umbilical side; umbilicus narrow, deep; aperture
asymmetrically placed at base of last chamber,
intereriomarginal, umbilical-extraumbilical; high,
smooth or beaded (but not muricate) face to final
chamber above aperture; chambers on spiral side
tangentially longer than broad; sutures curved, generally
obscured by muricate ornament; peripheral margin
subangular in edge view.
Size: Maximum diameter of holotype 0.29 mm,
thickness 0.26 mm. |
| Discussion / Comments: |
Toumarkine & Luterbacher (1985):
The last whorl of the compact test has 3 to 4 somewhat compressed chambers which are longer than wide on the spiral side. The umbilicus is small, but deep. The aperture, which is umbilical to extraumbilical-umbilical in position has a distinct lip. The surface is covered with coarse blunt spines or pustules.
Jenkins (1985):
The small subquadrate test of A. primitiva distinguishes it from other Acarinina species. Because of this test shape it was placed in Pseudogloboquadrina by Jenkins (1966a). In New Zealand A. primitiva has a long range from the Late Paleocene to the Middle Eocene. A similar range was recorded at DSDP Leg 29 Site 277 south of New Zealand (Jenkins, 1975), and ranges of Middle Eocene at DSDP Leg 40 Site 360 and Late Paleocene to Early Eocene at Site 362 (Tournarkine, 1978).

Pearson et al. (2006):
DISTINGUISHING FEATURES.-
Distinguished by
triangular (broadly wedge-shaped) chambers;
asymmetrically situated aperture resulting in distinct
projection of umbilical face of last chamber over the
umbilicus. Acarinina coalingensis has more rounded,
inflated chambers than A. primitiva and lacks the straight,
incised intercameral sutures on the umbilical side.
DISCUSSION.-
The outward, superficial morphologic
similarity of the type species primitiva to that of the
Neogene globoquadrinid form Globoquadrina dehiscens
led Jenkins (1965b) to create the generic name
Pseudogloboquadrina for Eocene morphotypes, but the
morphology is similar to other Paleogene acarininids and
this name is unnecessary (see also Blow, 1979, p. 950).
Acarinina primitiva is the dominant acarininid
in middle Eocene austral assemblages and its
disappearance/extinction in the late middle Eocene
(?Chron C18n) is a useful datum level for regional
correlation. See discussion in Berggren and Norris (1 997, p. 69), Olsson and others (1999, p. 437) and above for
A. coalingensis for further relevant data.
PHYLOGENETIC RELATIONSHIPS.-
This form
descended from Acarinina coalingensis in the early
Eocene by means of developing a more subquadrate test
and concomitant sutural incision and chamber separation
in the final whorl.
STRATIGRAPHIC RANGE.-
Zone E6 to Zone E13.
Berggren and others (2000) recorded the lowest/earliest
occurrence of A. primitiva in association with the lowest/
earliest A. coalingensis in Zone P4c and Chron C25r
and C25n at DSDP Site 384 in the northwest Atlantic
Ocean (see also compilation in Berggren and others,
1995, p. 155); we now regard these records as referable
to A. coalingensis. The last occurrence datum has been
fixed by Huber (1991) to lower Zone APl 1 at Sites 738
Kerguelen Plateau, by Stott and Kennett (l 990) to a level
in mid-Chron C 18n at ODP Site 689 on Maud Rise and
by Berggren (1992) to a level within/slightly above
questionable Chron 18n at Site 748, Kerguelen Plateau,
which is approximately equivalent to Zone E13 in the
(sub)tropics.
GEOGRAPHIC DISTRIBUTION.-
Essentially
temperate-high latitude (austral; South Indian Ocean and
Subantarctic Ocean distribution; less commonly reported
in low latitudes (Caribbean, Atlantic, Indo-Pacific).
