The Middle to Late Cretaceous microbiostratigraphy (foraminifera) and lithostratigraphy of the Cauvery Basin, Southeast India by Archana Tewari, B.Sc, M.Sc. A thesis submitted to the University of Plymouth in partial fulfilment for the degree of DOCTOR OF PHILOSOPHY Department of Geological Sciences University of Plymouth Drake Circus, Plymouth PL4 8AA, UK.

The planktonic and benthonic foraminifera are used to establish microbiostratigraphic zonations for the mid-Cretaceous succession in the Basin; leading to the first proposal of a benthonic foraminiferal zonation scheme. The schemes are primarily defined for regional application. In the absence of a formal lithostratigraphic classification for the Cretaceous succession in the Basin, a revised lithostratigraphy, in line with standard stratigraphic procedure, is proposed. The systematic taxonomy of the foraminifera studied is documented and revised in line with Western standards. The study shows that, in contrast to the standard European forms, the fauna fi-om the Cauvery Basin is composed of more robust individuals. The study also shows some interesting differences in the planktonic foraminifera fi*om the standard Tethyan assemblage. Comparative studies indicate a longer time range for some of the "index" species and more ornamented forms in the Cauvery Basin. The study records two levels, (I) in the late Albian and (2) fi-om the late Cenomanian to mid-Turonian, when anoxic conditions developed in the Basin. These anoxic events record major taxonomic changes in the planktonic foraminiferal assemblage. The study shows that the anoxic events had a major affect on the microfaunal community and that the post anoxic microfaunal population was dominated by more robust and heavily ornamented individuals. The planktonic foraminifera are used to identify the mid-Cretaceous sea-level changes in the Basin. The pattern of evolution and expansion of the planktonic foraminifera suggest a continuously rising sea-level in the mid-Cretaceous; with four periods of major transgressions. These levels are, at the late Albian, mid-Cenomanian, late Cenomanian-early Turonian and mid-Turonian. The pattern of sea-level changes in the Cauvery Basin followed , in general, the global sea-level curve, but has been influenced by local factors particularly tectonics. A pilot study demonstrates how palaeontology (including ichnology) in conjunction with sedimentology and stratigraphy is used to apply sequence stratigraphy concepts to the late Turonian-Coniacian succession in the Basin. A comprehensive study of Teredolites-infested fossil wood documents the morphological characters of the wood and its palaeoenvironmental significance. The study shows that there exists a close link between the influx of the fossil wood and sea-level dynamics.

These species are listed according to the classification of Loeblish & Tappan (1988), updated for the Recent species by Debenay et al. (1996). Their affinity with microfaunas from other regions is briefly discussed. Resume La compilation des travaux sur les foramini:feres actuels et quaternaires recoltes dans les eaux entourant la Nouvelle-Caledonie nous a permis de repertorier 574 especes. Ces especes sont presen­ tees selon la classification de Loeblish & Tappan (1988), mise ajour pour les especes actuelles par Debenay et al. (1996). Leur affinite avec les microfaunes d'autres regions est discutee brievement. Introduction The first study about foraminifera from the southwestern Pacific near New Caledonia was carried out by Brady (1884) during the voyage of H.M.S. Challenger (1873-1876), updated by Barker (1960), The nearest station was station 177, near Vanuatu (16°45'S-168°5'E). However, studies concerning directly New Caledonia began much later, with partial and local inventories in coastal samples (Gambini,1958, 1959; Renaud-Debyser, 1965; Toulouse, 1965, 1966). Samples of recent and fossil sediments collected during the Singer-Polignac mission (1960-1965) were further used for several studies of foraminiferal assemblages (Coudray & Margerel, 1974; Coudray, 1976; Margerel, 1981).
  • Tasmanian Tertiary Foraminifera

    Tasmanian Tertiary Foraminifera

    Papers and Proceedings of the Royal Society of Tasmania, Volume 108 (ms. received 16.3.1973) TASMANIAN TERTIARY FORAMINIFERA Part 1. Textulariina, Miliolina, Nodosariacea by Patrick G. Quilty West Australian Petroleum Pty. Limited, Perth, W.A. (with four plates) ABSTRACT Foraminifera of the Suborders Textulariina and Miliolina and the Superfamily Nodosariacea are recorded from samples of all known Tasmanian marine Oligo-Miocene sections. Thirteen species of agglutinated foraminifera are identified specifically and one category is left in open nomenclature. Thirty species of porcellanous foraminifera (including CrenuZostomina banksi n. gen., n. sp.) are recorded and there are eight open categories. The Nodosariacea is represented by 63 identified species (including Lagena tasmaniae n. sp.) and 10 categories in open nomenclature. Information on each species includes original citation, synonymy of Australian identifications, remarks where necessary and occurrence and age in Tasmania. All identified forms are figured. INTRODUCTION AND ACKNOWLEDGEMENTS The stratigraphy of the Tasmanian Tertiary Marine succession has been reviewed by Quilty (1972). The results noted in that paper are based on foraminiferal studies conducted at the University of Tasmania. Localities, sample numbers etc., mentioned here are detailed further in Quilty (op. cit.) and this paper should be read in company with that paper. This paper is the first of a projected series of three papers documenting the Tasmanian Tertiary foraminifera. Classification adopted in these papers follows closely that proposed by Loeblich and Tappan (1964a) and reviewed by them (1964b) but differs in minor respects which will be indicated where necessary. Quilty (op. cit.) noted that the first record of Tasmanian Tertiary foraminifera was by Goddard and Jensen (1907).

E-mail: [email protected] Abstract We describe for the first time subtropical intertidal foraminiferal assemblages from beach sands on São Vincente, Cape Verdes. Sixty-five benthic foraminiferal species were recognised, representing 47 genera, 31 families, and 8 superfamilies. Endemic species were not recognised. The new checklist largely extends an earlier record of nine benthic foraminiferal species from fossil carbonate sands on the island. Bolivina striatula, Rosalina vilardeboana and Millettiana milletti dominated the living (rose Bengal stained) fauna, while Elphidium crispum, Amphistegina gibbosa, Quinqueloculina seminulum, Ammonia tepida, Triloculina rotunda and Glabratella patelliformis dominated the dead assemblages. The living fauna lacks species typical for coarse-grained substrates. Instead, there were species that had a planktonic stage in their life cycle. The living fauna therefore received a substantial contribution of floating species and propagules that may have endured a long transport by surface ocean currents. The dead assemblages largely differed from the living fauna and contained redeposited tests deriving from a rhodolith-mollusc carbonate facies at <20 m water depth.

Carlton Co-Editors’ Note: This is one of the papers from the special issue of Aquatic Invasions on “Transoceanic Dispersal of Marine Life from Japan to North America and the Hawaiian Islands as a Result of the Japanese Earthquake and Tsunami of 2011." The special issue was supported by funding provided by the Ministry of the Environment (MOE) of the Government of Japan through the North Pacific Marine Science Organization (PICES). Abstract This is the first report of long-distance transoceanic dispersal of coastal, shallow-water benthic foraminifera by ocean rafting, documenting survival and reproduction for up to four years. Fouling was sampled on rafted items (set adrift by the Tohoku tsunami that struck northeastern Honshu in March 2011) landing in North America and the Hawaiian Islands. Seventeen species of shallow-water benthic foraminifera were recovered from these debris objects. Eleven species are regarded as having been acquired in Japan, while two additional species (Planogypsina squamiformis (Chapman, 1901) and Homotrema rubra (Lamarck, 1816)) were obtained in the Indo-Pacific as those objects drifted into shallow tropical waters before turning north and east to North America.

It possesses a distinctive composite wall made of a continuous, agglutinated layer discontinuously covered by secondary hyaline outer deposits. Its taxonomic position, phylogeny, morphology, wall structure, and compo- sition have been debated for a long time. Based on abundant, well-preserved material from the Danian of the Kambühel Formation in the Northern Calcareous Alps, Austria, we identify elements in the here emended species Stomatorbina binkhorsti which support a strong affinity to the order Textulariida, within the genus Stomatorbina Dorreen, 1948. Usually regarded as free (non-fixing), S. binkhorsti is here illustrated attached to small bioclasts in high-energy carbonate settings. The attached specimens are juvenile forms with a wall covered by massive hyaline deposits. This observation suggests that secondary lamellar parts added to the wall may have served for stabilisation or fixation to the substrate. Rosalina binkhorsti Reuss, 1862, war eine in den Flachwassermeeren der Oberkreide und des frühen Paläogens kos- mopolitische benthonische Foraminifere. Sie besitzt eine zusammengesetzte Wand, bestehend aus einer kontinuierlichen agglutinierten Lage welche diskontinuierlich von äusseren sekundär-hyalinen Abschnitten bedeckt ist.

Borissiak Paleontological Institute, Russian Academy of Sciences, Laboratory of Protistology, Profsoyuznaya 123, 117997 Moscow, Russia; [email protected] 2 Zavaritsky Institute of Geology and Geochemistry, Ural Branch, Russian Academy of Sciences, Pochtovyi per. 7, Yekaterinburg 620151, Russia; [email protected] The origin, basic evolutionary patterns, and great biotic crises in Phanerozoic radiolarian develop- ment were intimately connected with the geological history of the Earth. Glaciations and cold climate played a special role in radiolarian evolution. Radiolarians, which were typical for warm interglacial periods (greenhouse) disappeared during interglacial to glacial transition intervals (icehouse), and vice versa. Some possible regularities that resulted in increase radiolarian interglacial biodiversity, could be circumstanced by stabilization of climate and enhanced oceanic production. Biological mechanism, explaining these events, may be caused by phenomenon of solitary population waves (Kovalev, 2007). New species constantly appear under both favourable and severe conditions. Therefore, it is in- correct to propose that changes in global climatic conditions necessarily result in general deterioration of conditions in the habitats of all species. A crisis for some taxa is a chance for others (Kovalev et al., 2007; Chernykh et al., 2007). New morphological formations occurred usually under general stress. They probably invaded into global radiolarian fauna like a pandemic virus and instantaneously mi- grated to populations of remote water areas. Processes of expansion of species with morphological and/or physiological innovations into new ecological systems and adaptation to new niches are re- garded as different phases of existence of populations.

    Palaeontologia Electronica palaeo-electronica.org Neogene benthic foraminifera from the southern Bering Sea (IODP Expedition 323) Eiichi Setoyama and Michael A. Kaminski ABSTRACT This study describes a total of 95 calcareous benthic foraminiferal taxa from the Pliocene–Pleistocene recovered from IODP Hole U1341B in the southern Bering Sea with illustrations produced with an optical microscope and SEM. The benthic foramin- iferal assemblages are mostly dominated by calcareous taxa, and poorly diversified agglutinated forms are rare or often absent, comprising only minor components. Elon- gate, tapered, and/or flattened planispiral infaunal morphotypes are common or domi- nate the assemblages reflecting the persistent high-productivity and hypoxic conditions in the deep Bering Sea. Most of the species found in the cores are long-ranging, but we observe the extinction of several cylindrical forms that disappeared during the mid- Pleistocene Climatic Transition. Eiichi Setoyama.

These studies revealed some unexpected groupings of rotaliid genera. However, the support for the new clades was rather weak, mainly because of the limited length of the analysed fragment.
