Species Globigerinatheka index Finlay 1939


Diagnosis / Definition:
Pearson et al. (2006):
DESCRIPTION:- Type of wall: spinose, cancellate, frequently encrusted, with mainly cylindrical pores, about 0.04-0.05 mm in diameter. Test morphology: Test slightly elongate, subrectangular in outline, rather compact, broadly rounded and subrectangular in side view; early chambers poorly visible, arranged in a low trochospire of possibly 2-3 whorls, with the last whorl consiting of 3 inflated chambers at least twice as large as earlier chambers, antepenultimate and penultimate chambers of almost equal size separated by a vertical suture in umbilical view, the last chamber making almost one-half of the whole test; sutures of the inner chambers poorly visible, possibly straight or slightly curved, sutures in the last whorl distinct, deeply incised, straight and radial; primary aperture, umbilical, a rather high and large, symmetrical arch, at the base of the last chamber frequently bordered by a thick lip, two medium-sized, semicircular arched, secondary apertures at the base of the last chamber above the sutures ofprevious chambers. Bullae are not common. Size: Dimensions for population range from 0.35 mm to 0.55 mm. Diameter of the holotype 0.4 mm.
Discussion / Comments:
Jenkins (1985):
G. index has a subspherical test with fairly large, high arched apertures at the base of the final chamber; the holotype figured here has only one. Within its Middle to Late Eocene range, G. index is a fairly common species in New Zealand. It has also been recorded in the Middle Late Eocene of South Australia (Ludbrook &Lindsay, 1969), south of New Zealand at DSDP Leg 29 Site 277 (Jenkins, 1975) and at the Leg 40 Sites 360 and 362A (Tournarkine, 1978).
Van Eijden & Smit (1991):
Remarks. Small specimens, usually with globular chambers and lacking accessory apertures, occur much more commonly than the species. Their distribution is listed under Globigerinatheka sp. cf. G. index.
Pearson et al. (2006):
DISTINGUISHING FEATURES.- Globigcrinatheka index is distinguished by its well defined incised sutures and large, high-arched, primary aperture located above the suture between the first two chambers of the final whorl. This taxon differs from G, tropicalis by its semicircular, rimmed apertures and deeply incised distinct sutures. DISCUSSION.- At high latitudes (including the type locality), specimens of G. index with typically incised sutures commonly hisplay poorly developed secondary spiral apertures or are even devoid of them. Even though the overall shape, which recalls some Neogene Globigerinoides, and the incised sutures differentiate G. index from all other globigerinathekids, this species has frequently been misidentified (see synonymy list). Hagn (1 956) described Globigerinoides macrostoma as a new species. According to Bolli (1 972), G. macrostoma should be considered as a junior synonym of G. index, with which it shares the same features: Hagn's figures of the specimen he identified as G. index is in fact attributable to G. tropicalis, and he created the new species G. macrostoma for the 'true G. index'. Judging from the original figures, the paratype of G. index illustrated by Finlay in his fig. 87 seems to exhibit some similarities in general shape with G. korotkovi Keller, but redrawing of Finlay's paratype by Hornibrook (1958) shows well the incised sutures lacking in Ke11er's secies. PHYLOGENETIC RELATTONSHIPS.- There is a general agreement that G. index is related to G. tropicalis, which is its tropical equivalent according to Blow (1969) and Jenkins (1971). GEOGRAPHIC DISTRIBUTION.- Cosmopolitan, but more abundant in high latitudes. STABLE ISOTOPE PALEOBIOL0GY.- Stable isotope data indicates depleted ò18O and enriched ò13C values suggesting a mixed layer habitat, comparable to co-occurring Acarinina, but possibly with a greater tendency to sink at gametogenesis (Boersma and others, 1979; Pearson and others, 1993,200 l). This paleohabitat is supported by boron isotope data (Pearson and Palmer, 1999).
