A comparison between smaller (>63 μm) and larger (>150 μm) planktonic foraminiferal faunas from the Pleistocene of ODP Site 1073 (Leg 174A), New Jersey margin, NW Atlantic Ocean
Authors: Smart Christopher W.
Published: July 2010

Abstract. Planktonic foraminiferal faunas have been studied from the Pleistocene of ODP Site 1073 (Leg 174A), New Jersey margin, NW Atlantic Ocean and their abundances have been compared in the >63 μm and >150 μm size-fractions from the same samples. Trends in the relative abundance of many species are similar in the two size-fractions, although the general level varies considerably. The mean abundance and ranges of Neogloboquadrina pachyderma (sinistral), N. pachyderma (dextral), Globorotalia inflata and Globigerina bulloides are greater in the >150 μm size-fraction compared with the >63 μm size-fraction. Turborotalita quinqueloba, Globigerinita uvula, G. glutinata, G. clarkei, and juvenile species are more abundant in the >63 μm size-fraction than the >150 μm size-fraction. Peaks (c. 60%) in abundance of G. uvula occur in the >63 μm size-fraction only, although the causes of these patterns are unclear. The data suggest that, in general, consistent palaeoclimatic/palaeoceanographic information is achieved by studying planktonic foraminiferal faunas from either size-fraction. However, because particular smaller species are either under-represented or even absent from the larger (>150 μm) size-fraction, the smaller (>63 μm) size-fraction must be included in studies of planktonic foraminifera. Furthermore, studies that involve planktonic foraminifera in the >63 μm size-fraction could provide different transfer function estimates for sea surface temperatures in areas where workers have only used larger (>125 μm and >150 μm) size-fractions.

Authors: Mischke Steffen , Herzschuh Ulrike , Kürschner Harald , Chen Fahu , Meng Fei , Sun Zhencheng
Published: July 2010

Abstract. To our knowledge, the Qilian Mountains in NW China have been investigated with respect to Recent or sub-Recent ostracods for the first time. The Qilian Mountains (95–103°E/37–40°N) extend along the northeastern margin of the Tibetan Plateau reaching a maximum altitude of 5826 m above sea-level (m asl).In September 2001, surface mud from the bottom of various water bodies including brooks, rivers and small shallow meadow and oxbow pools were sampled at an altitude ranging from 2900 m to 3570 m asl. In addition, surface mud samples and short cores were obtained from the small (c. 1 km2) and shallow (<0.4 m) freshwater Lake Luanhaizi situated at about 3200 m asl.Ostracod valves were usually abundant in all of the 32 samples and comprised the taxa listed in Table 1, some of which are illustrated in Plate 1.The recorded taxa are mainly distributed in the holarctic realm but Fabaeformiscandona danielopoli and Ilyocypris echinata appear to be restricted to the cold mountainous regions in China (Huang, 1985; Wang & Zhu, 1991; Sun et al., 1995; Yin & Martens, 1997).Following the first survey, a 14 m long core was drilled in Lake Luanhaizi in January 2002 which is currently under multidisciplinary investigation to reconstruct the Holocene vegetation and climatic history of the Qilian Mountains.
A replacement name for Agerina Farinacci, 1991 (Foraminifera) non Tjernvik, 1956
Authors: Turvey Samuel T.
Published: July 2010

Abstract. Farinacci (1991) proposed the generic name Agerina for a Pliensbachian (Early Jurassic) foraminiferan from the Central Apennines, Italy. This name is a junior homonym of Agerina Tjernvik, 1956 and Agerina Farinacci, 1991 is replaced herein with the new generic name Agerella, which retains Professor Farinacci’s dedication to Professor D. V. Ager. Professor Farinacci was informed of the homonymy, in keeping with the Code of Ethics of the International Code of Zoological Nomenclature (ICZN, 1999, p. 124, Appendix A, item 3) and gave her consent for this revision.

On the origin and evolution of a new anchialine stygobitic Microceratina species (Crustacea, Ostracoda) from Christmas Island (Indian Ocean)
Authors: Namiotko Tadeusz , Wouters Karel , Danielopol Dan L. , Humphreys William F.
Published: July 2010

Abstract. Marine species of the ostracod genus Microceratina Swanson (Cytheruridae, Eucytherurinae) were until now known only from their hard parts, the valves and carapaces, as no living animals have been described. Here we report the first living population, from a tropical anchialine cave. The description of the limbs and hard parts of this new taxon, M. martensi sp. nov., enhances our understanding of the origin and evolution of the cave-dwelling Microceratina – the new species and M. pseudoamfibola (Barbeito-Gonzalez) from an anchialine cave in Southern Italy – and clarifies their affinities with other Eucytherurinae species. Microceratina is known from both Recent and fossil species (Quaternary, Tertiary and Late Cretaceous) from shelf and deep-sea habitats and/or sedimentary facies, located in the Pacific Ocean (along the Australian and New Zealand coasts), the Mediterranean (Greece and Italy), the North Atlantic (British Isles) and the Baltic Sea (Rügen Island). This suggests that the Microceratina group spread through the expanding Tethys Ocean. The morphological traits of the two cave-dwelling species reflect their ecological conditions. Cave-dwelling Microceratina species appear to have originated from epigean shallow water species predisposed to colonize subterranean habitats.
Palaeocopida (Ostracoda) across the Permian–Triassic events: new data from southwestern Taurus (Turkey)
Authors: Crasquin-Soleau Sylvie , Marcoux Jean , Angiolini Lucia , Nicora Alda
Published: July 2010

Abstract. The Palaeocopida have been considered as an entirely Palaeozoic group and their disappearance as a marker for the Palaeozoic–Mesozoic boundary. Despite this, 11 Palaeocopida species have been recorded in the Early Triassic. New data obtained in southwestern Taurus at the Permian– Triassic section of Çürük daǧ, permit an assessment of this problem. This paper synthesizes the data on lowermost Triassic ostracodes and revises the youngest Palaecopida occurrences. A new Early Triassic Palaeocopida species is described (Reviya curukensis n. sp.).
Cyclic changes in oxygenation based on foraminiferal microhabitats: Early–Middle Pleistocene, Lucania Basin (southern Italy)
Authors: Stefanelli Simona
Published: July 2010

Abstract. In the Pleistocene Montalbano Jonico composite section (southern Italy) the microhabitat preferences of the benthic foraminifera have been determined by comparison with data on living forms. The stratigraphic distribution of the different living positions seems to be related to the cyclic oxygen fluctuations recorded in the succession. In the high-oxygenated phases, when the oxygenated zone within the sediment column is wide, the assemblages show a distinct vertical microhabitat distribution. In the low-oxygenated phases, when the minor oxygen availability at the bottom–water interface reduces the oxygen penetration within the sediment, infaunal microhabitat is the preferred living depth.In order to quantify the oxygen fluctuations recorded in the succession, a palaeo-oxygen curve is reconstructed testing Kaiho’s benthic foraminiferal oxygen index (BFOI) in the equation: y=1.686+ 0.033337x. In general, good correlations are observed between the dissolved oxygen regimes and the benthic assemblage composition. The low-oxygenated phases are identified with the low-medium oxic regime and the high-oxygenated phases with the high oxic regime.In the deeper part of the composite section, oxygen has played an important role on the foraminiferal assemblage composition. In contrast, in the shallower part, a combination of oxygen and sea-level changes regulates the distribution and composition of the assemblages.
Tetratropis terrina sp. nov., a new calcareous dinoflagellate cyst from the Upper Campanian polyplocum zone of Lägerdorf (NW Germany)
Authors: Bison Katarzyna-Maria , Wendler Jens , Versteegh Gerard J. M. , Willems Helmut
Published: July 2010

Abstract. A new calcareous dinoflagellate cyst species, Tetratropis terrina sp. nov., with an apparent stratigraphically narrow range is described from the Upper Campanian Bostrychoceras polyplocum zone of the Lägerdorf chalk sequence (NW Germany). The electron microscopic and light microscopic analyses show that T. terrina has both a pithonelloid wall type with uniformly inclined wall crystallites and a reduced peridiniacean paratabulation pattern. The prominent morphological similarities of T. terrina to the other two Tetratropis species (T. patina and T. corbula) justify the affiliation of the new species to the genus. As a result of the extension of the morphological spectrum by the new species, the genus Tetratropis Willems, 1990 has been emended.
A boreal early cradle of Angiosperms? Angiosperm-like pollen from the Middle Triassic of the Barents Sea (Norway)
Authors: Hochuli Peter A. , Feist-Burkhardt Susanne
Published: July 2010

Abstract. The origin of flowering plants is still a matter of dispute. Several lines of evidence suggest that their origin may go back to the Triassic. This paper reports on pollen grains with angiosperm-like morphologies from marine Middle Triassic sediments of the Boreal Realm (Norwegian Arctic, Barents Sea area). The morphology of these pollen grains is comparable to forms recorded from the Early Cretaceous, which are generally attributed to angiosperms. The new finds of angiosperm-like pollen are the earliest in the fossil record so far and show an astonishing high diversity. In contrast to other early records, they come from high palaeolatitudes with an inferred warm-temperate climate. The new finds suggest the presence of the first angiosperms during the Middle Triassic (242–227 Ma) or, alternatively, provide evidence for an as-yet unknown group of gymnosperms, possibly an extinct sister group of the flowering plants.
Dinoflagellate cysts and acritarchs from the Oligocene–Lower Miocene interval of the Alma-1X well, Danish North Sea
Authors: Schiøler Poul
Published: July 2010

Abstract. This palynological study of cuttings samples from the Lark Formation in the Danish North Sea well Alma-1X documents for the first time in the public domain the succession of last occurrences of dinoflagellate cysts and acritarchs in the Oligocene–Lower Miocene interval of the Central North Sea. The distribution of dinoflagellates and acritarchs in the well demonstrates the potential for the development of a detailed subdivision of the Oligocene–Lower Miocene in the Central North Sea, based on the first downhole occurrences of key taxa. Five regional intra-Lark Formation seismic and petrophysical log markers can be dated with precision using dinoflagellate biostratigraphy. Four new species and one new subspecies of dinoflagellates are described from the study interval: Amphorosphaeridium? almae sp. nov., Filisphaera pachyderma sp. nov., Pentadinium corium sp. nov., Spiniferites pseudofurcatus verrucosus ssp. nov. and Thalassiphora rota sp. nov. Pseudospiniferites manumii Lund, 2002 is emended and transferred to the genus Spiniferites.
On the award of TMS Honorary Membership, 17 November 2004 Professor Robin Whatley – an appreciation
Authors: Lord Alan R. , Whittaker John E.
Published: July 2010

Abstract. Robin Charles (Ignatius) Whatley was born a ‘Man of Kent’ in 1936. He was educated at Ashford Grammar School, where an inspiring teacher, Frank Kenworthy, stimulated a series of pupils to become earth scientists, for example, John Catt (University College London), Roy Clements (Leicester University), Ron Cook (recently Vice Chancellor of York University) and Chris Wilson (Open University). Following a varied post-school career as a farmer (1954), National Serviceman (1955–1957), and inshore fisherman based at Christchurch, Hampshire (1957–1959), Robin joined Hull University to read Geology. He graduated with a First Class Honours Degree in 1962, one of the first two ever to be awarded by the department. An interest in Micropalaeontology, in particular ostracods, became apparent during undergraduate years and formed part of his BSc dissertation. A further three years at Hull followed, funded by the Department of Scientific and Industrial Research (DSIR, fore-runner of the modern research councils), leading to the award of a PhD degree in 1966 for a thesis on British Callovian and Oxfordian ostracods, carried out under the supervision of John Neale. As a mature student Robin felt it to be his duty to write stern letters to DSIR pointing out the shortcomings of its procedures and officials, and he was somewhat surprised when, visiting DSIR for a Post-Doctoral Fellowship interview, he discovered that his letters were regularly pinned to the staff notice board to be read by all. As it turned out a Fellowship was not required, as Robin was appointed Assistant Lecturer in Geology . . .
Late Asbian to Brigantian (Mississippian) foraminifera from southeast Ireland: comparison with northern England assemblages
Authors: Somerville Ian D. , Cózar Pedro
Published: July 2010

Abstract. Foraminiferal assemblages from platform carbonates in the Carlow district (SE Ireland) are analysed. This platform contains a near-continuous succession of Upper Asbian to lower Upper Brigantian strata. Detailed sampling of several quarry and borehole sections allows characterization of foraminiferal assemblages throughout the succession. Assemblages typifying the Late Asbian, Early Brigantian and Late Brigantian are described, with the most common genera and species, as well as the guides for the recognition of these substages. In addition, three successive faunal events are recognized within the Early Brigantian. A comparison with northern England foraminiferal assemblages from the Asbian and Brigantian stratotype sections shows a great similarity in the recorded taxa. Furthermore, these taxa have closely comparable stratigraphical ranges, demonstrating the biostratigraphic utility of these foraminifera throughout Ireland and Britain. Taxa proposed here as guides for the basal Brigantian are potentially an alternative to the previously published taxa (which are either unrecorded, or recorded at higher stratigraphic levels in the Brigantian).
First occurrence of the genus Sclerocypris Sars, 1924 (Ostracoda) in the ?Pleistocene of Western Europe (Portugal)

Abstract. The Recent distribution of the freshwater ostracod genus Sclerocypris Sars, 1924 (type species Sclerocypris clavularis Sars, 1924; synonyms Bharatcypris Battish, 1978 and Candonopsis Sars, 1894 pro parte), subfamily Megalocypridinae Rome, 1965, is restricted to Africa and India (Martens, 1986; Martens & Coomans, 1990).Recovery of fossils of Sclerocypris are not frequent and are restricted to Plio-Quaternary deposits of Kenya, with Sclerocypris clavularis Sars, 1924 from Lakes Turkana and Bogoria (Carbonel & Peypouquet, 1979; Carbonel et al., 1983, 1987; Cohen et al., 1983) and Sclerocypris jenkinae Klie, 1933 from Lakes Elmenteita and Naivasha (Lindroth, 1953; Cohen & Nielsen, 1986) and the Pliocene basal member of the Omo Series, Lake Turkana (Peypouquet et al., 1979). Sclerocypris bicornis (G. W. Müller, 1900) has been recorded (identified as Chlamydotheca sp.) in the Pleistocene of Egypt (Boukhari & Guernet, 1985).Recent field work in Algarve, southern Portugal (Cabral et al., 2003, 2004, 2005), recorded the presence of Sclerocypris. It was represented by numerous juvenile specimens of a species related closely to the Recent species Sclerocypris bicornis in a probable Pleistocene lacustrine ostracod assemblage at Bolqueime associated with other Cypididae, Candonidae, Darwinulidae, Limnocytheridae and Cypridopsidae. The instars are characterized by the presence of long spines on the margins, as is common in many species of this genus (Martens, 1986, 1991), such as Sclerocypris tuberculata (Methuen, 1910), Sclerocypris venusta (Vavra, 1897) [illustrated in Martens, 1986] and Sclerocypris clavularis Sars, 1924 (Pl. 1, fig. 2).

Early Permian Carbonitidae (Ostracoda): ontogeny, affinity, environment and systematics
Authors: Retrum Julie B. , Kaesler Roger L.
Published: July 2010

Abstract. An assemblage of four Carbonita species was deposited with charophytes, lungfishes and lysorophids in a lenticular mudstone from a Cisuralian freshwater pond deposit from the lowest Permian. Samples contained few adult Carbonita, indicating perhaps a stressed and unstable environment. Two species new to science, C. ovata n. sp. and C. triangulata n. sp., occur together with C. evelinae and C. pungens. Morphological characters of these Carbonita suggest an affinity with the Healdioidea, marine taxa that are probably ancestral to the Carbonitidae. The muscle-scar patterns of Carbonitidae, which comprise closely grouped circular bundles of secondary muscle scars, resemble closely those of Healdioidea and not those of Cypridoidea and Cytheroidea, whose muscle scars are fewer and spaced further apart. The muscle-scar pattern of C. pungens, described here for the first time, is a circular scar with an ascertainable pattern of secondary scars. C. pungens and species of Darwinula are morphologically similar, but study of additional specimens of C. pungens with better-preserved muscle scars is essential to determine their evolutionary affinity.
Late Miocene siliceous endoskeletal dinoflagellates from the Sawai Bay Formation, Neill Island, Andaman Sea, India
Authors: Rai Jyotsana
Published: July 2010

Abstract. Siliceous spicules of endoskeletal dinoflagellates form a very small part of the siliceous microfossil assemblage from Neill Island, Ritchie’s Archipelago, Andaman Island and Nicobar Island. They are represented here by a solitary genus, Actiniscus, with two species – Actiniscus pentasterias and Actiniscus elongatus. Light microscopy, supported by scanning electron microscopy, illustrates its remarkable symmetry and geometry. Though biostratigraphically unimportant, this genus has considerable value in deriving palaeoecological interpretations. Their association with age-diagnostic calcareous nannofossil taxa indicates that the glauconitic mudstones of the Sawai Bay Formation of Nipple Hill and East Coast sections are Late Miocene in age, equivalent to the Discoaster berggrenii Subzone (Subzone CN9A) corresponding to the lower part of the Discoaster quinqueramus Zone (Zone NN11).
The Hawaiian megatsunami of 110±10 ka: the use of microfossils in detection
Authors: Williams Mark , Wilkinson Ian P. , Tappin David R. , Mcmurtry Gary , Fryer Gerard J.
Published: July 2010

Abstract. INTRODUCTIONMcMurtry et al. (2004) described a thin (c. 20–50 cm) bioclastic, carbonate gravel from the NW coast of Hawaii, on the flanks of the extinct Kohala volcano (Fig. 1). This unit is found between modern altitudes of c. 1.5–61 m above sea-level. The deposit is sandwiched between a fossil soil below and a modern soil above in Keawe’ula Bay (Fig. 2). Dating of coral fragments from within the deposit indicate an age of 110±10 ka (McMurtry et al., 2004). Given rates of subsidence on Hawaii, this would place the deposit at an original palaeo-altitude up to 491 m. The deposit contains a range of bioclasts including bivalves, gastropods, corals, bryozoans and foraminifera, largely representing assemblages from a reef flat. The geological setting of the unit, coupled with the evidence from the contained marine fossils, indicate a megatsunami genesis, probably linked to the collapse of the submarine Alika Slide at about 120 ka and with a run-up in excess of 400 m and at least 6 km inland (McMurtry et al., 2004).FOSSILS PRESERVED IN THE TSUNAMI DEPOSITFossils of the tsunami, and adjacent deposits, have been collected at 14 sites (material is deposited in the collections of the British Geological Survey, registered as MPA51883–51891, 51893–51897). Further information is available in BGS archives (see report IR/02/197R, available through the BGS library at: http://www.bgs.ac.uk and http://geolib.bgs.ac.uk).The tsunami deposit on the flank of Kohala volcano contains a range of macrofossil debris and prolific microfauna (Fig. 3).

Middle Pleistocene Ostracoda from a large freshwater lake in the presently dry Qaidam Basin (NW China)
Authors: Mischke Steffen , Herzschuh Ulrike , Sun Zhencheng , Qiao Zizhen , Sun Naida , Zander Anja M.
Published: July 2010

Abstract. Ostracods of Middle Pleistocene age were recovered from an escarpment at the northeastern margin of the large Qarhan playa surface in the Qaidam Basin (NW China). The Middle Pleistocene age of the sampled Quan Ji section was determined by means of Optically Stimulated Luminescence (OSL) dating of seven sediment samples. Among the 31 ostracod taxa identified in total, only Eucypris gyirongensis, Leucocythere dorsotuberosa and Prionocypris gansenensis seem to be restricted to high-altitude sites in Central Asia whereas most taxa are known from a number of European and Siberian (Palaeoarctic) or even Holarctic sites. Laterally widespread sediments and the ostracods from the Quan Ji section suggest the formation of a large freshwater to oligohaline lake of at least several metres in depth in the Qaidam Basin, which is presently dry apart from a few shallow salt lakes.

The type material of the Miocene to Recent species Globigerinoides sacculifer (Brady) revisited
Authors: Williams Mark , Schmidt Daniela N. , Wilkinson Ian P. , Miller C. Giles , Taylor Paul D.
Published: July 2010

Abstract. The detailed test morphology of the type suite of specimens for the planktonic foraminifer Globigerinoides sacculifer (Brady) is illustrated for the first time since the species was identified in 1877. Fossil representatives of this species are a key index for oceanographic reconstruction of the Neogene and Quaternary tropics. The types of G. sacculifer, sourced from a loose ‘chalk’ block on a beach in New Ireland, Papua New Guinea, all bear a sac-like terminal chamber and are heavily calcified. They have undergone gametogenesis. Scanning electron microscopy identifies calcite fabrics of the test that were formed post-ontogenetically.
Celebrating 25 years of advances in micropalaeontology: a review

Published: July 2010

Abstract. INTRODUCTION (F. JOHN GREGORY)To commemorate the publication of the 25th Volume of the Journal of Micropalaeontology, the first issue of which came out in 1982, this celebratory review article was commissioned. Officers of each TMS Group (Ostracod, Foraminifera, Palynology, Nannofossil, Microvertebrate and Silicofossil) were requested to reflect over the last 25 years and assess the major advances and innovations in each of their disciplines. It is obvious from the presentations that all Groups report that research has moved on from the basic, but essential descriptive phase, i.e. taxonomy and establishing biostratigraphies, to the utilization of new technologies and application to issues of the day such as climate change and global warming. However, we must not lose sight of the fact that the foundation of micropalaeontology is observation and the building block for all these new and exciting innovations and developments is still good taxonomy. Briefly, the most obvious conclusion that can be drawn from this review is that micropalaeontology as a science is in relatively good health, but we have to ensure that the reported advancements will sustain and progress our discipline. There is one issue that has not really been highlighted in these contributions – we need to make sure that there are enough people being trained in micropalaeontology to maintain development. The last 25 years has seen a dramatic decrease in the number of post-graduate MSc courses in micropalaeontology. For example, in the UK, in the 1980s and early 1990s there were five specific MSc courses to choose . . .
Organic-walled dinoflagellate cyst stratigraphy in an expanded Oligocene–Miocene boundary section in the eastern North Sea Basin (Frida-1 Well, Denmark) and correlation from basinal to marginal areas
Authors: Dybkjær Karen , Rasmussen Erik Skovbjerg
Published: July 2010

Abstract. The organic-walled dinoflagellate cyst (dinocyst) assemblages in an unusually thick (>800m) Oligocene–Miocene boundary succession from the eastern North Sea Basin (the Frida-1 Well) were studied. Six successive dinocyst assemblages are described: the Wetzeliella gochtii Assemblage (early Chattian), the Distatodinium biffii Assemblage (Chattian), the Deflandrea phosphoritica Assemblage (latest Chattian), the Homotryblium spp. Assemblage (early Aquitanian), the Caligodinium amiculum Assemblage (Aquitanian) and the Cordosphaeridium cantharellus Assemblage (latest Aquitanian to early Burdigalian). The dinocyst assemblages are compared with informal dinocyst zonations proposed for the southern North Sea Basin (Germany, Belgium and the Netherlands).A correlation of the expanded basinal succession in Frida-1 with the marginal marine succession found onshore Jylland, based on the dinocyst stratigraphy combined with well logs and seismic data, is proposed. This correlation confirms earlier proposed datings of the onshore deposits and the presence of several hiati. Furthermore, the correlation made it possible to subdivide the succession in Frida-1 into the sequences A–C, as defined onshore. The Mi-1 glaciation event and thus the Oligocene–Miocene boundary are proposed to correlate to the boundary between sequences A and B.
Latest Permian Entactinaria (Radiolaria) from southern Guangxi, China

Published: July 2010

Abstract. A highly diverse and well-preserved latest Permian radiolarian fauna was obtained from muddy siliceous rocks and siliceous mudstones of the Dalong Formation, southern Guangxi, China. Specimens of the Order Entactinaria were selected for taxonomic study. Thirty-four species, among which were nine new species and twelve unidentified species, are included in this investigation. The nine new species are Entactinia wangi, Entactinia minuta, Entactinia sashidai, Trilonche textiles, Triaenosphaera variabilis, Triaenosphaera megacantha, Provisocyntra densa, Provisocyntra ormistoni and Wuyia dongpanica. Permian species of the Family Spongentactiniidae Nazarov are reported first and the extinction pattern of the Order Entactinaria is discussed.
The Pennsylvanian conodont genus Gondolella Stauffer & Plummer, 1932: reinterpretation of the original type specimens and concepts
Authors: Merrill Glen K. , Von Bitter Peter H.
Published: July 2010

Abstract. In order to ensure stability of nomenclature among species of Gondolella, lectotypes are selected from among the cotypes (syntypes in modern usage) proposed by Stauffer & Plummer (1932) for species that it is concluded were parts of the apparatuses of two species of that genus. It is recognized that many of their specimens actually represent growth stages of individual species, and many of the names used by Stauffer & Plummer are placed in synonymy. Interpreted synonyms include not only gondolelli-form P1 elements, but other parts of the apparatus, especially P2 elements assigned to Euprioniodina by Stauffer & Plummer. Thus, Gondolella bella has synonyms as P1 elements: G. curvata, G. magna, G. minuta, probably G. sp. A, S1 element Euprioniodina coronata and P2 elements: E. exserta, E. eximia and E. intertexta. In a similar manner, the type species of the genus, Gondolella elegantula, has synonyms G. insolita, G. lanceolata (P1 elements), and probably Euprioniodina sp. B (P2 element?).
Morphometrics of the Late Devonian conodont genus Palmatolepis: phylogenetic, geographical and ecological contributions of a generic approach
Authors: Girard Catherine , Renaud Sabrina , Feist Raimund
Published: July 2010

Abstract. Studying the palaeobiology of extinct organisms relies on assessing the relevant scale of morphometric differentiation corresponding to the evolutionary units in the group. On the time-slice of the latest Frasnian, sampled in nine outcrops from three distant palaeogeographical domains (Laurussia, northwest and northeast Gondwana), the morphological pattern of differentiation of the conodont genus of Palmatolepis was analysed based on the outline of its platform elements. A generic approach was used that challenged the concept of species in this genus but supported the distinction between two subgenera. In the samples considered here, Palmatolepis Palmatolepis includes the single species linguiformis, and Palmatolepis Manticolepis appears as a homogeneous group composed of a single species or a complex of closely related species. The former displays mostly an isometric growth whereas the allometric growth of the latter means that the difference between the two subgenera increases with the size of the elements. Shape difference of an element belonging to the feeding apparatus may be related to differences in ecology. Hence, the differences in size and shape between the two subgenera may be interpreted as related to differences in their ecological preferences and life history traits.
Ceramic micropalaeontology: the analysis of microfossils in ancient ceramics
Authors: Quinn Patrick S. , Day Peter M.
Published: July 2010

Abstract. Microfossils can be a common component of ancient ceramic artefacts. Their analysis in this unusual context is a little-known, yet promising, cross-disciplinary application of micropalaeontology. This article presents the first detailed assessment of the phenomenon of microfossils in ancient ceramics and demonstrates how micropalaeontology can contribute to a range of issues in archaeological ceramic analysis and the reconstruction of the human past. In describing a methodology by which micropalaeontologists and archaeologists can analyse microfossiliferous ceramics, this paper presents the foundations of an approach, which is here referred to as ‘ceramic micropalaeontology’.
Latest Permian deep-water ostracods from southwestern Guangxi, South China
Authors: Yuan Aihua , Crasquin-Soleau Sylvie , Feng Qinglai , Gu Songzhu
Published: July 2010

Abstract. A very diverse ostracod fauna was discovered in the latest Permian strata of the Dongpan section, southwestern Guangxi, South China. Fifty-one species belonging to twenty-eight genera were identified and described, including two new species (Bairdia dongpanensis n. sp. and Spinomicrocheilinella anterocompressa n. sp). This type of assemblage, with nineteen palaeopsychrospheric species and four pelagic species, is the first world-wide deep-water ostracod fauna reported from the latest Permian strata and the first one recorded in the Permian of China. The palaeoenvironmental analysis allows one to propose an evaluation of the bathymetry variation along the Dongpan section.

Together they comprise 14% of the total Recent ostracod fauna described from the Solomon Islands. In the main the hemicytherids are much more endemic than the thaerocytherids. Three new species have been recorded only from the Solomon Islands, and three species of Caudites, held in open nomenclature due to their rarity, are also probably endemic to the islands. Another three new species have been recorded only from Java and one species of Mimicocythere gen. et sp. nov. also occurs in Australia. The six new species described and illustrated are: Ambostracon (A.) micropapillatum, A. (A.) micromaculata, Caudites shortlandensis, ?C. atypicus, Mutilus dissimilis ssp. nov. and Mimicocythere pseudomelobesoides gen. et sp. nov. Only one of the hemicytherids, Caudites javana Kingma, occurs throughout the Indo-Pacific. It is the Thaerocytheridae, however, that are almost pandemic in tropical regions, with Tenedocythere deltoides and T. transoceanica being distributed particularly widely. A new species of the rare genus Neobuntonia, N. subalata sp. nov., only the second modern species to be described, is also illustrated.
Acarinina multicamerata n. sp. (Foraminifera): a new marker for the Paleocene–Eocene thermal maximum
Authors: Guasti Elisa , Speijer Robert P.
Published: July 2010

Abstract. During the Paleocene–Eocene thermal maximum (PETM), low to mid-latitude planktic foraminiferal assemblages were characterized by blooms of the surface-dwelling Acarinina. Among this group a new ‘excursion taxon’ is identified, Acarinina multicamerata n. sp. Previously, this taxon was lumped together with Acarinina sibaiyaensis El-Naggar. Considering that A. sibaiyaensis already occurred prior to the hyperthermal event, both in open ocean and ocean margin deposits, it is proposed that these taxa are differentiated in order to avoid taxonomic and biostratigraphic ambiguities. Acarinina multicamerata n. sp. occurred exclusively during the PETM, hence this taxon represents an excellent biostrati-graphic marker of the PETM, while its common occurrence in various marine settings makes it an excellent marker of Subzone P5b or its new equivalent zone E1.
Holocene ostracod palaeobiogeography of the Seto Inland Sea, Japan: impact of opening of the strait
Authors: Yasuhara Moriaki
Published: July 2010

Abstract. In this study, published Holocene ostracod data for Osaka, Hiroshima, and Iyo-nada Bays within the Seto Inland Sea (SIS), Japan, are re-examined. Five major faunal changes are recognized at different stratigraphic horizons (Horizons 1–5) in the Holocene sedimentary record. Horizons 1 and 5 (faunal changes) were most likely triggered by the respective openings of the Bisan-seto (and resulting formation of the SIS) and Akashi Straits. Three other major faunal changes, at Horizons 2–4, may also be linked to the opening of straits and resulting formation of bays, although the exact nature of these events is less certain. This re-examination indicates that the opening of straits extensively affected the benthic inner-bay community during the Holocene transgression in the SIS. Further high-resolution studies are needed for confirmation of faunal changes triggered by opening of straits.
Pliocene ostracods (Crustacea) from the Togakushi area, central Japan; palaeobiogeography of trans-Arctic taxa and Japan Sea endemic species
Authors: Ozawa Hirokazu , Nagamori Hideaki , Tanabe Tomotaka
Published: July 2010

Abstract. Pliocene strata (4–3 Ma) in the Togakushi area, central Japan, yield significant ostracods, which allow investigation of the origins of high-latitude (Arctic–Atlantic) taxa and the Japan Sea endemic species, together with their post-Miocene history of extinction-speciation and migration. Three types of extinct species are found here: (1) cryophilic species in common with, or closely related to, species in Plio-Pleistocene assemblages described from the Japan Sea; (2) species closely related to, or comparable with, species that characterize Miocene Japan; and (3) species endemic to the Pliocene Japan Sea. Type (1) contains species closely related to high-latitude species known from the Arctic and northern Atlantic Oceans. Their presence suggests migration from the northwestern Pacific to the northern Atlantic through the Arctic seas since the Late Pliocene after the opening of the Bering Strait. Both Types (2) and (3) contain genera originating in the south, which show high specific diversity in regions affected by the modern warm Kuroshio Current. Ancestral ostracods of Types (2) and (3) invaded the Japan Sea from the Pacific from the Middle Miocene, and diversified to produce closely related species in the semi land-locked Japan Sea until the Early Pliocene. Two new species Aurila togakushiensis sp. nov. and Aurila shigaramiensis sp. nov. are described.
Taxonomy and palaeoecology of Ostracoda from the Middle to Late Pleistocene upper Karewa formation of Kashmir Valley, Northern India
Authors: Kramer Michael , Holmes Jonathan
Published: July 2010

Abstract. Ostracoda from a 25 m thick exposure in sediments of the upper Karewa formation indicate lacustrine conditions in the Kashmir intermontane basin during the Middle to Late Pleistocene. The Middle to Late Pleistocene age is established on the basis of lithostratigraphy and confirmed by two thermoluminescence age determinations at the top of the section. The ostracod assemblages show that the lake water remained fresh or, at most, was very slightly saline, throughout the period represented by the section. Nearly all ostracod taxa identified from the sediments are cold stenothermal forms and they include inhabitants of the littoral and profundal domain as well as running waters and springs. The Ostracoda present within the section indicate that during deposition of the upper Karewa sediments a large, but fairly shallow, well-oxygenated open-basin freshwater lake existed in that central part of the Kashmir Basin. Although the sequences suggest changes in water depth may have occurred, lacustrine conditions were otherwise largely unchanged over the period represented by the section, up until the demise of the lake during the early part of the Late Pleistocene.
Chitinozoans and the age of the Soom Shale, an Ordovician black shale Lagerstätte, South Africa
Authors: Vandenbroucke Thijs R. A. , Gabbott Sarah E. , Paris Florentin , Aldridge Richard J. , Theron Johannes N.
Published: July 2010

Abstract. Isolated chitinozoans from the Soom Shale Member of the Cedarberg Formation, SW South Africa are described and provide a date of the latest Hirnantian–earliest Rhuddanian. The recovered chitinozoans are typical of the latest Ordovician Spinachitina oulebsiri Biozone, although an earliest Silurian age is possible. They indicate a very short time span (less than 1 Ma) across the Ordovician–Silurian boundary. This is currently the highest biostratigraphical resolution attainable for the Soom Shale Lagerstätte. Correlation of the Soom Shale chitinozoans with identical assemblages in post-glacial, transgressive deposits of Northern Africa is possible; both faunas occur in shales that overlie glacial diamictites of the Hirnantian glaciation. A new species, Spinachitina verniersi n. sp. is described.
The biostratigraphy of the Upper Pliensbachian-Toarcian (Lower Jurassic) sequence at Ilminster, Somerset

Published: July 2010

Abstract. Temporary road sections for the A303 bypass at Ilminster, Somerset, revealed Upper Pliensbachian and Toarcian sediments from an alternating limestone–marl facies, in marked contrast to the limestone-dominated Dorset coast succession. The lithostratigraphy is described, with the standard ammonite zonation providing chronostratigraphical correlation. The uppermost Pliensbachian (Spinatum Chronozone) and much of the Toarcian (Serpentinum, Bifrons, Variabilis, Thouarsense and Pseudoradiosa chronozones) of the classic Dorset coast Lower Jurassic sequence are represented by the Beacon Limestone Formation, formerly the ‘Junction Bed’ (a highly condensed carbonate deposit). The Tenuicostatum Chronozone is largely missing from the sequence. Elsewhere in southern and eastern England this interval is poorly or rarely exposed. The argillaceous units have yielded rich microfaunas and -floras (foraminifera, ostracods, calcareous nannofossils and palynomorphs), the biostratigraphical distributions of which are analysed and discussed in relation to contemporary evolutionary patterns and other UK records. This study provides an insight into the micro-biostratigraphy of the Late Pliensbachian to Toarcian interval for onshore southern England.
Revised stratigraphy of the lower Cenozoic succession of the Greater Indus Basin in Pakistan

Published: July 2010

Abstract. A refined stratigraphy for the lower Cenozoic succession of the Greater Indus Basin in Pakistan is presented. This region preserves an important East Tethyan marine succession through the Paleocene–Eocene, but its interpretation in terms of regional (tectonic) and global (climatic) effects has been inhibited by poor stratigraphy. Established dinoflagellate, nannofossil, planktonic foraminiferal and shallow benthonic foraminiferal biostratigraphical data for the Greater Indus Basin in Pakistan are collated, reinterpreted (where necessary) and correlated with the global standard chronostratigraphy and biostratigraphy of the early Palaeogene. Inter-regional stratigraphical correlations for the Upper Indus Basin and Lower Indus Basin are resolved. Age-diagnostic larger benthonic foraminifera from the Late Paleocene Lockhart Formation are illustrated. These collective biostratigraphical data provide a means of interpreting the lithostratigraphy and physical stratigraphical relationships of the Palaeogene succession in terms of the interplay between local tectonics (India–Asia collision) and global sea-level change. The timing of the Tethys closure, initial and final contact of the Indian–Asian plates, and dispersal of land mammals on the Indian Plate are discussed and correlated in the stratigraphical record of the basin.
Megaspore assemblages from the Åre Formation (Rhaetian–Pliensbachian) offshore mid-Norway, and their value as field and regional stratigraphical markers

Abstract. A megaspore biozonation of the non-marine Åre Formation is proposed, based on a micropalaeontological analysis of key Haltenbanken area wells (Block 6608/11). The lower part of the Åre Formation is divisible into Banksisporites pinguis, Nathorstisporites hopliticus and Horstisporites areolatus zones, and subzones, occupying the Rhaetian–Hettangian interval. In the upper Åre Formation a marked turnover of megaspore assemblages is evident, with the appearance of several species of Trileites and the mesofossil Kuqaia quadrata. On this basis, the biozonation is extended into the Sinemurian–Pliensbachian, with the recognition of the Kuqaia quadrata Zone and subzones. Reference to selected wells in the Urd Field (Block 6608/10) and further south demonstrates that these biozones correlate across the northern Haltenbanken region. Biozonal boundaries are calibrated with miospore/microplankton markers where possible, to provide a robust bio-chronostratigraphical framework with which to evaluate the stratigraphy of the Åre Formation and its reservoir units. Comparison with published European biostratigraphical data shows that a similar megaspore succession exists through the Rhaeto-Liassic interval, with shifts in megaspore composition occurring within the same time intervals. On this evidence it is suggested that the megaspore biozones identified are regionally extensive and may reflect palaeoclimatic controls on the distribution of the megaspore-producing plants. It is concluded that megaspores are a stratigraphically important microfossil group, which should be utilized routinely in Upper Triassic–Jurassic oil field and regional biostratigraphical studies.

Abstract. After six years in office as the editor of the Journal of Micropalaeontology, my time in post has come to an end, and as this will be my final issue of the Journal it is time to hand over the reins. At the AGM of TMS a new editor was elected; Professor Alan Lord and I know that he will do a great job.As has been reported over the last year or so at the AGM and in TMS Newsletter, there will be some significant changes afoot for the Journal which I have been involved with over the last couple of years. This negotiation has resulted in a new publishing contract for the Journal of Micropalaeontology with the Geological Society of London (GSL), and its publisher the Geological Society Publishing House (GSPH). This will relieve our Society of the financial burden of paying for the production of the Journal. We will exercise the same editorial control we have always had, and although the GSPH is run as a commercial concern by the Geological Society they, as a learned society themselves, place great emphasis on not interfering with the running of society Journals, and respect the academic nature of our science. The format of the Journal will remain the same, with continued emphasis on excellent international science and high-quality plate production.There will, however, be some significant changes regarding the way papers are submitted and dealt with. The main one will be the initiation of online submission and manuscript handling . . .
Occurrence of Vestalenula (Darwinuloidea, Ostracoda) in the Neogene of Italy, Crete and Serbia, with the description of three new species

Published: July 2010

Abstract. The morphology of fossil remains of Vestalenula (Darwinuloidea, Ostracoda) from Crete (Greece), Serbia and Italy were analysed using morphometric valve variability analysis. Three new species were distinguished and described, Vestalenula angulata n. sp., Vestalenula longissima n. sp. and Vestalenula pliocenica n. sp., and represent the first record of this genus in the Neogene of Italy and Serbia. Vestalenula angulata n. sp. was recorded from the early Messinian of Tuscany, Italy (Baccinello and Velona Basins), Vestalenula longissima n. sp. was collected in the Upper Pliocene (Gelasian) sediment core drilled in the Sabina area (Latium, Italy), and Vestalenula pliocenica n. sp. was collected from the Early Tortonian of Vrysses (Rethymnon Basin, Crete), from the lower Messinian deposits of the Velona Basin (Tuscany, Italy), in the Late Pliocene of the Paludinian Beds (Middle Danube Plain) and Mazgoš deposits (Serbia), and in the Upper Pliocene deposits of the Sabina area (Latium, Italy). Despite the freshwater character of most living species of Vestalenula, the fossil species here analysed were found associated with halotolerant forms, showing they could also withstand oligohaline conditions.
