Palaeo-environmental models, nostly derived from micropalaeontological and sedimentological criteria, are proposed for the distribution of the foraminiferal morphogroups. The palaeogeographic reconstructicn of the studied area, frcsn the upper Aptian to Maastrichtian, is presented. A refined raicrobiostratigraphic zonation scheme, based on ali secticns studied, is proposed and primarily defined for regional applicatici. Ihe conposition and distribution patterns of the foraminiferal assanblages (diversity and abundance of norphogrOLÇJs) are shown to be a direct respcxise to overall palaeoceanographic conditicns and to conmunity strategies of exploitation of the trophic resources in the microhabitats. The foraminifera recovered - from the oldest, late i^tian, marine sediments reveal a characteristic Tethyan affinity and suggest that this area had at least minimal surface water exchange with low latitude central North fttlantic-western Tethyan bicprovinces, even possibly at intermediate (epi- to mesopelagic) water depths. A shallow Calcite Conpensaticn D^th within Upper mesopelagic depths (c. 3Q0~500m) is inferred for the Upper Aptian-Albian. Twelve foraminiferal palaeocoitnoinities can be recognised in the succession. These are characterised by the relative dorainance of the major foraminiferal groups and related to variations in trophic structures. Iheir palaeo-environnental distributicn is proposed as a model with référence to the Sergipe Cretaceous séquence. Radiolarians and diatoms are documented for the first time from the mid-Cretaceous succession of the Sergipe Basin. Prevailing palaeoceanograj*iic conditicns are inferred for the épisodes of siliceous radiolarian and diatcsn bicBtiineralization/preservaticn. The study indicates that intermittent hypoxic/anoxic events occurred in the basin, most likely associated with the Interplay of various processes. Three nexima in oxygen depletiíMi (dysaerobic-anaerobic conditicns) are recorded in the succession : Ist) in the iipper Äptian-lowernost Albian; 2nd) in the lower Cenomanian; 3rd) in the uppermost Cenomanian-lowermost Turonian. Waning low-oxygen conditiois (dys^robic to aérobic) are apparent in the middle-içjper Albian and middle-ufper Turonian to Ccniacian. - I - DECLARATION I hereby dedare that the work submitted in partiaL fiilfilment of the requirements fot the Degree of Doctor oE PhilosofAiy under the tibie "MID- TO LATE CRETACEOUS MICROHEOSTRATEGRAPHY, PALAEO-ECOLOGY AND PALAEOGEOGRAPHY OF THE SERGIPE BASIN, NORTHEASTERN BRAZIL" is the true result of my own independent originai research.

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.

  • Foraminiferal Evidence for Inner Neritic Deposition of Lower Cretaceous (Upper Aptian) Radiolarian-Rich Black Shales on the Western Australian Margin
    Journal of Micropalaeontology, 24: 55–75. 0262-821X/05 $15.00 2005 The Micropalaeontological Society Foraminiferal evidence for inner neritic deposition of Lower Cretaceous (Upper Aptian) radiolarian-rich black shales on the Western Australian margin DAVID W. HAIG School of Earth & Geographical Sciences, The University of Western Australia, 35 Stirling Highway, Crawley 6009, Australia (e-mail: [email protected]). ABSTRACT – Diverse foraminifera, Lingula-like brachiopods and the geological setting indicate that Aptian radiolarian-rich black shales forming the Windalia Radiolarite were deposited at water depths probably less than 40 m in the Southern Carnarvon Basin. Elsewhere in Australia, coeval radiolarian-rich deposits are widespread in other western-margin basins and in vast interior basins. The organic-rich mudstones containing the radiolaria include the foraminiferal Ammobaculites Association, a sparse benthic macrofauna and kerogens of mainly terrestrial plant origin. The deposits suggest that there was substantial high-nutrient freshwater input into the epeiric seas as well as high levels of dissolved silica resulting from marine flooding of a mature silicate-rich landscape bordered on the eastern and western continental margins by large volcanic provinces. The widespread presence of organic-rich muds through the broad, shallow Southern Carnarvon Basin and through the coeval interior basins suggests that regional geomorphology controlled the distribution of eutrophic facies in the Australian Aptian rather than any global expansion of the oceanic oxygen minimum zone. The foraminiferal assemblage from the Windalia Radiolarite consists of calcareous hyaline benthic types (diverse Lagenida as well as abundant Lingulogavelinella, Epistomina and Coryphostoma) and organic-cemented agglutinated species (including common Ammobaculites humei, Haplophragmoides–Recurvoides spp., and Verneuilinoides howchini).

Chamber arrangement versus wall structure in the high-rank phylogenetic classification of Fora- minifera. Acta Palaeontologica Polonica 64 (1): 1–18. Foraminiferal wall micro/ultra-structures of Recent and well-preserved Jurassic (Bathonian) foraminifers of distinct for- aminiferal high-rank taxonomic groups, Globothalamea (Rotaliida, Robertinida, and Textulariida), Miliolida, Spirillinata and Lagenata, are presented. Both calcite-cemented agglutinated and entirely calcareous foraminiferal walls have been investigated. Original test ultra-structures of Jurassic foraminifers are given for the first time. “Monocrystalline” wall-type which characterizes the class Spirillinata is documented in high resolution imaging. Globothalamea, Lagenata, porcel- aneous representatives of Tubothalamea and Spirillinata display four different major types of wall-structure which may be related to distinct calcification processes. It confirms that these distinct molecular groups evolved separately, probably from single-chambered monothalamids, and independently developed unique wall types. Studied Jurassic simple bilocular taxa, characterized by undivided spiralling or irregular tubes, are composed of miliolid-type needle-shaped crystallites. In turn, spirillinid “monocrystalline” test structure has only been recorded within more complex, multilocular taxa pos- sessing secondary subdivided chambers: Jurassic

On the basis of the integration of publications, reports and theses with new available data from the Kuwait Bay and the northern islands, this study infers the total benthic foraminiferal diversity within Kuwait territorial water. This new literature survey documents the presence of 451 species belonging to 156 genera, 64 families, 31 superfamilies and 9 orders. These values are relatively high in consideration of the limited extension and the shallow depth of the Kuwait territorial water. Kuwait waters offer a variety of different environments and sub-environments (low salinity/muddy areas in the northern part, embayment, rocky tidal flats, coral reef systems, islands and shelf slope) that all together host largely diversified benthic foraminiferal communities. These figures are herein considered as underestimated because of the grouping of unassigned species due to the lack of reference collections and materials, as well as the neglection of the soft-shell monothalamids (‘allogromiids’).

Holbourn2 and Michel Moullade3 ABSTRACT Lower Cretaceous benthic foraminiferal assemblages from basal sedimentary sequences of Holes 959D, 962B, and 962D pro- vide time constraints for the onset of marine sedimentation on the Côte d’Ivoire-Ghana Transform Margin and show that marine conditions were already established by late Aptian–early Albian near Hole 959D and by mid to late Albian near Hole 962D. The foraminiferal data suggest that older Aptian–Albian marine sequences were subsequently reworked into upper Albian–lowermost Cenomanian sediments within tectonically active sub-basins. Marked fluctuations in test size, abundance, and diversity reflect a pulsed sedimentation pattern with an overall high accumulation rate. Three main cycles of deposition are detected from overall changes in preservation, abundance and diversity, which are possibly related to major shifts in sediment provenance and/or sup- ply. The composition of the benthic foraminiferal assemblages at Holes 959D and 962D indicates an outer shelf to upper bathyal setting and reflects a combination of Tethyan, South Atlantic, and local endemic faunal influences, pointing to restricted connec- tions with the open ocean and Tethys during the late Albian and early Cenomanian. There is no evidence for bottom-water anoxia or severe dysoxia during the deposition of Cores 159-962D-16R through 37R. The high dissolution of planktonic tests and absence or scarcity of benthic foraminifers in the upper part of the sequence (Sections 159-962D-7R-1 through 13R-1 and 159- 962B-8H-5 through 9H-6) indicate some later deterioration in bottom-water oxygenation.

Nine sediment cores were taken Received 5 October 2014 near the spill site and environmental factors including Polycyclic Aromatic Hydrocarbon (PAHs), oils, sul- Revised 12 May 2015 fides, organic carbon were measured 6 months later. Benthic foraminifera were separated into >150 lm Accepted 12 May 2015 (large) and 63–150 lm (small) size fractions for 2-cm depth interval of each sediment core. Statistical Available online xxxx analyses suggested that the species composition of living foraminifera was impacted by oils, PAHs and sulfides. Large foraminifera were more sensitive to the oils than the small. Abnormal specimens were Keywords: positively correlated with oils or PAHs. Small forms, however, tended to have high reproduction and mor- Benthic foraminifera tality. Pollution-resistant and opportunistic taxa were identified to calculate a Foraminiferal Index of Biological response Ecological monitoring Environmental Impacts (FIEI).
