Original Description

Large, low trochospiral test, with 5 inflated chambers in the final whorl; 14 globular chambers in 2 - whorls, gradually increasing in size, last chamber smaller then the penultimate one; penultimate whorl with 4 chambers; chambers loosely coiled, periphery lobate; sutures radial, deeply incised. Umbilicus very large, open, quadrangular elongated (not completly visible, filled with sediment); aperture a very low umbilical arch; penultimate chamber opens into the umbilicus. Wall spinose, as in Globigerina s. str. with spine holes, spine bases and inter-pore ridges in earlier chambers.

Size:
holotype: maximum diameter 0.35 mm.

Etymology:
In honor of Dr. Ludwig WAGNER, Wien, for his subsurface studies of the Upper Austrian Molasse Basin, and his continuous interest in micropaleonto- logy and stratigraphy.

Extra details from original publication
General morphology: The size of the test varies between 0.28 and 0.56mm, with an average diameter of about 0.4 mm. Generally all specimens exhibit a low trochospiral test with loosely coiled chambers; 4 to 5 chambers in the final whorl, and 4 chambers in the penultimate one; the umbilicus is always large and open, with the last 2-3 chambers opening into it; the last chamber may vary in size and in position relative to the umbilicus, resulting in a somewhat umbilical extraumbilical aperture; the aperture is without a lip, but may contain a small imperforate band. In some specimens commonly the penultimate chamber is inflated, sacklike and transverse to the coiling direction.

Remarks : In a first comparison this species exhibits a relationship to Globigerina fariasi BERMUDEZ (1961), described from the middle Oligocene of Cuba. The latter species has a very high trochospiral test which is circular in outline; the holotype has a diameter of 0.4 mm. A sketch of the holotype is given in text-fig. 1. SPEZZAFERRI & PREMOLI SILVA (1992) record G. fariasi from zone P 22, late Oligocene in the Gulf of Mexico; but the specimen of PL IV, figs. 7a-b, named "Globigerina" ciperoensis BOLLI compares more closely to G. fariasi.

It is very interesting that a geographically wide-spread horizon of large globigerinids occurs in the middle Oligocene in the Central Paratethys and the Caribbean. Globoquadrina globularis BERMUDEZ (1961) and Globoquadrina winkleri (BERMUDEZ, 1961) also characterize this assemblage of large globigerinids. In the Austrian sites the specimens are commonly filled with pyrite or limonite, often preserved only as casts, as are the other larger faunal elements. These large globigerinids are also observed in the same time interval in the Prealps, Haute Savoie, France (UJETZ & WERNLI, this volume).

The accompanying planktonic assemblage consists of Globigerina ciperoensis BOLLI, Gg. labiacrassata JENKINS, Gg. officinalis SUBBOTINA, Gg. ouachitaensis HOWE & WALLACE, Gg. praebulloides BLOW, Globoquadrina globularis BERMUDEZ, Gq. winkleri (BERMUDEZ), Paragloborotalia opima opima (BOLLI) (only in the upper part of distribution), P. opima nana (BOLLI), Beella rohiensis (POPESCU), Tenuitella liverovskae (BYKOVA). In addition, in the Kiscellian Subbotina angiporoides (HORNIBROOK), S. cryptomphala (GLAESSNER), S. gortanii (BORSETTI), and S. praeturritillina (BLOW & BANNER), appear. The benthic foraminifera fauna is characterized by the common occurrence of large inflated Bulimina, Chilostomella, Allomorphina, Loxostomum chalkophilum, Cancris, generally all pyritized, and non-pyritized Uvigerina (sometimes in floods). Pyritized casts of pteropods are common. To the East in continuation of the Alpine foredeep these large globigerinas are not observed, but otherwise a similar development is observed in the lower Oligocene of the Polish Carpathians (OLSZEWSKA 1985).

Stratigraphic distribution: Oligocene, Kiscellian to lower Egerian of the Central Paratethys. In the Upper Austrian Molasse Basin this species occurs in the "Bändermergel", "Rupel-Tonmergelstufe" and the Lower Puchkirchen formation; in the imbricated zone from the lower Oligocene upwards.

Investigated material: drill sites in the Upper Austrian Molasse Basin (Schallerbach-2, Hochburg-1, Perwang-1, Zupfing-1); counter-flash drill site CF-N6 in the imbricated zone; Ottenthal, Waschberg unit, Lower Austria (farm yard L. HAUER, Ottenthal no. 138, coll. F. RÖGL).
