Emig.- Sur l'origine du nom de genre Thecidea, une révision.- Le genre Thecidea a été illustré avant d'être décrit ce qui a donné lieu à des interprétations diverses et erronées, notamment par des auteurs anglophones. Ce travail montre qu'il doit indubitablement être attribué à Defrance in Cuvier & Brongniart (1822). Les autres descriptions dérivées du nom originel Thecidea sont des nomen nullum, et sont en partie responsable de confusion et d'erreurs avant que ce genre n'éclate en plusieurs nouveaux genres répartis dans diverses autres familles et sous-familles. En outre, Thecidea ne comporte plus aujourd'hui que des espèces fossiles. L'histoire de l'attribution du nom d'auteur à ce genre est décrite en détail au cours du XIXe siècle. L'espèce-type et ses synonymes, ainsi que la classification du genre Thecidea sont mentionnées.- SRef-ID: http://overview.sref.org/1634-0744/CG2012_A08.- Handle-ID: http://hdl.handle.net/2042/48306 Article carnetsdegeologie@hotmail.com Mon, 10 Dec 2012 14:13:44 GMT http://paleopolis.rediris.es/cg/CG2012_M02/ Nico M.M. Janssen, Arnaud Clément & Willem Bont.- Mediterranean Neocomian belemnites, part 4: belemnites of the Barremian stratotype section.- This paper deals with the distribution of belemnites in the latest Hauterivian to early Bedoulian of the Angles Barremian Stratotype Section (ABSS). The distribution of the belemnites in the ABSS is not uniform, mainly due to the inaccessibility of certain beds. To cover this, and to compare the distribution with more proximal settings, we investigated a section to the north of Le Bourguet. The latest Hauterivian sediments mainly yield Hibolithes ex gr. subfusiformis besides some Duvalia ex gr. dilatata. The earliest Barremian sediments deliver a richer association that yields the last Hibolithes spp. The first typical Barremian belemnites occur just one bed above the Hauterivian-Barremian boundary based on ammonites. This belemnite association (BaBA1) consists of Duvalia ex gr. silesiaca-gagrica, Duvalia pontica and several species of Hibolithes. At the boundary between the Nicklesia pulchella and the Kotetishvilia compressissima zones the diversity increases and the first classical Barremian belemnites occur. These were formerly attributed to Mesohibolites (BaBA2). These species are herein attributed to a new genus Shvetsovia. Together with the duvaliids from BaBA1 they were first described from Abkhasia by Shvetsov (1913). The latest Early Barremian (BaBA3) and the earliest Late Barremian (BaBA4) show well diversified belemnite associations, with many classical species, dominated by few genera closely resembling the true Mesohibolites. Eventually, these belemnite associations are compared to more proximal sections within the Vocontian Basin, and areas outside the Vocontian Basin (chiefly Hungary and Georgia). Some differences in the frequency and abundance of several species in these different palaeogeographical settings are believed to indicate differences in natural habitat. Duvalia ex gr. grasiana appears to be more abundant in more distal sections, while juvenile Mesohibolitidae, Conohibolites and Curtohibolites appear to be more abundant in the more proximal environments. Finally, a biozonation is presented and defined based on the distribution of the belemnites in the ABSS. This biozonation appears applicable in the more proximal sections, although some biozones are diachronous. The first Mesohibolites occur in the Upper Barremian Imerites giraudi Zone. In the Barremian-Bedoulian boundary sediments, as defined in the ABSS, Neohibolites first occurs, but the latter is only dominant in the marly sediments above the "calcareous Bedoulian". In the Late Barremian-early Bedoulian seven main belemnite associations can be distinguished, viz. BaBA5, BaBA6, BaBA7, BdBA1, BdBA2, BdBA3 and BdBA4. The following new species and genera are described: Hibolithes keleptrishvilii sp. nov. (latest Hauterivian), Duvalia vermeuleni sp. nov. (Early Barremian), Curtohibolites (?) bourguetensis sp. nov. (Early Barremian), and Shvetsovia gen. nov. (late Early-early Late Barremian). Besides, the Late Barremian yields the new species Mesohibolites anglesensis. Moreover, eleven species are described in open-nomenclature.- SRef-ID: http://overview.sref.org/1634-0744/CG2012_M02.- Handle-ID: http://hdl.handle.net/2042/48307 Memoir carnetsdegeologie@hotmail.com Mon, 10 Dec 2012 11:40:47 GMT http://iopan.gda.pl/oceanologia/54_4.html * The impact of a non-uniform land surface on the radiation environment over an Arctic fjord - a study with a 3D radiative transfer model for stratus clouds over the Hornsund fjord, Spitsbergen.- Rozwadowska Anna, Górecka Izabela <br /> * Model dependences of the deactivation of phytoplankton pigment excitation energy on environmental conditions in the sea.- Ostrowska Mirosława <br /> * Modelled quantum yields and energy efficiency of fluorescence, photosynthesis and heat production by phytoplankton in the World Ocean:.- Ostrowska Mirosława , Woźniak Bogdan , Dera Jerzy <br /> * Inherent optical properties and remote sensing reflectance of Pomeranian lakes (Poland).- Ficek Dariusz, Meler Justyna, Zapadka Tomasz, Woźniak Bogdan, Dera Jerzy <br /> * Remote-sensing observations of coastal sub-mesoscale eddies in the south-eastern Baltic.- Gurova Evgenia, Chubarenko Boris <br /> * Influence of the wind field on the radiance of a marine shallow: evidence from the Caspian Sea:.- Karabashev Genrik S., Evdoshenko Marina A.<br /> * Water column conditions in a coastal lagoon near Jeddah, Red Sea:.- Albarakati Alaa M.

Wilson.- Encrustation and bioerosion on late Sheinwoodian (Wenlock, Silurian) stromatoporoids from Saaremaa, Estonia.- A shallow shelf carbonate platform (pelletal limestone facies) stromatoporoid association from the late Sheinwoodian of Saaremaa (Baltica) contains a diverse assemblage of sclerobionts (both epi- and endobionts). The studied stromatoporoids vary from low domical to extended domical shapes. Cornulites sp. aff. C. stromatoporoides, Conchicolites sp., Anticalyptraea calyptrata, microconchids, tabulate (Aulopora sp., Catenipora sp. and favositids) and rugose corals, sheet-like trepostome bryozoans, and discoidal crinoid holdfasts encrust the stromatoporoids. The dominant sclerozoans were tabulate and rugose corals, which is significantly different from several analogous Silurian sclerobiont communities. There may have been taxonomic polarity between an upper surface and a cryptic sclerozoan community. Bioerosion occurs as macroborings in 45.5 % of studied (N=22) stromatoporoids. Endobionts were represented by Trypanites and Palaeosabella borings, as well as embedded symbiotic rugose corals and Cornulites stromatoporoides.- SRef-ID: http://overview.sref.org/1634-0744/CG2012_A07.- Handle-ID: http://hdl.handle.net/2042/47551 Article carnetsdegeologie@hotmail.com Tue, 02 Oct 2012 14:10:58 GMT http://paleopolis.rediris.es/cg/CG2012_L03/ Michel Moullade, Guy Tronchetti, Christine Balme & Pascal Mauroux.- A new upper Bedoulian section in the Aptian stratotypic area: Croagnes (5 km NW of Gargas, Vaucluse, SE France).- The discovery and exploitation of a new outcrop of the "A1 Unit of yellow marls and marly limestones" of Leenhardt (1883), comprised between the Urgonian limestones and the "Aptian marls" of the authors, leads to question the generalized attribution of this formation to the Deshayesites grandis ammonite Subzone.

(Limnocytheridae, Timiriaseviinae), has been found for the first time in Iran. The strata containing this species are in the lower part of the Tarbur Formation in the interior Fars of the Zagros Mountains. The Late Maastrichtian age is indicated by rudists, larger foraminifers (Omphalocyclus macroporus, Loftusia spp.) and planktonic foraminifers (Contusotruncana contusa-Racemiguembelina fructicosa Zone) present in the upper part of the Tarbur Formation. The Maastrichtian age is confirmed by the occurrence in the same strata of the charophytes Platychara shanii, Peckichara cristellata and Stephanochara cf. producta. The genus Frambocythere Colin, 1980, was until now known mostly from the Upper Maastrichtian to Middle Eocene of southern Europe, India and China, as well as the Albian of the Democratic Republic of Congo.

Comparaison avec quelques localités de la Drôme et de l'Ardèche.- La récente révision critique de la Paléontologie française de d'Orbigny (1840-42, tome premier, texte et atlas, Terrains crétacés) ayant permis de mieux fixer le statut de l'Ammonites calypso (d'Orbigny, 1841), il s'avérait utile de préciser l'âge de l'espèce, au moins dans sa localité-type. Les auteurs du présent mémoire ont eu d'abord comme objectif de rechercher d'autres spécimens de l'espèce calypso dans les marnes valanginiennes de Senez-Lioux afin de lui attribuer un âge le plus fiable possible. Les Phylloceratoidea ne permettant pas une datation précise des niveaux de récolte des spécimens les auteurs ont déterminé les ammonites sur cinq niveaux successifs. Ce travail a permis de mettre en évidence le Valanginien inférieur et deux zones du Valanginien supérieur (zone à Verrucosum et zone à Peregrinus ?), la présence de cette dernière étant moins certaine. La zone à Furcillata, du Valanginien supérieur, n'a pas été mise en évidence. Les Phylloceratoidea abondent à Senez-Lioux. Six espèces ont pu être identifiées : Phylloceras (Hypophylloceras) serum (Oppel, 1865), Phylloceras (Hypophylloceras) tethys (d'Orbigny, 1841), Sowerbyceras calypso (d'Orbigny, 1841), Ptychophylloceras (Semisulcatoceras) semisulcatum semisulcatum (d'Orbigny, 1841), Ptychophylloceras (Semisulcatoceras) semisulcatum (d'Orbigny, 1841) diphyllum (d'Orbigny, 1841), Phyllopachyceras rogersi (Kitchin, 1908), ainsi qu'une nouvelle espèce Phylloceras (Goretophylloceras) liouxense n. sp. Cette espèce a été mise en évidence grâce au matériel récolté dans les Alpes-de-Haute-Provence et dans la Drôme (où le matériel a été récolté par Laurent Vareilles et Philippe Mercier). outes ces ammonites sont de petite taille de 5 à 28 mm. Dans les marnes valanginiennes il existe aussi des spécimens de diamètre inférieur à 5 mm, ils n'ont pu être déterminés et ne figurent pas dans cette étude. Cet ensemble paraît avoir été constitué par le naissain et de jeunes individus, le Bassin vocontien ayant été longtemps, semble-t-il, l'un des lieux de reproduction des Céphalopodes. La petite taille des spécimens n'est pas liée à leur nature pyriteuse ou en pyrite transformée en oxydes de fer, limonite par exemple. Il existe dans les faciès marneux de très grands spécimens pyriteux, parmi les plus grands connus (Joly, 2000, p. 173). Les plus petits spécimens de Senez-Lioux ne sont pas des adultes de petite taille, on n'observe pas le resserrement des dernières cloisons témoignant du ralentissement de croissance des adultes. Le début de la loge présent chez beaucoup de spécimens prouve que ces spécimens n'étaient pas des nuclei de spécimens plus grands. Ils n'avaient certainement pas atteint la maturité sexuelle. Le grand nombre de spécimens récoltés a permis une étude statistique des populations (ou assemblages, terme préférable en paléontologie) surtout pour les espèces Phylloceras (Hypophylloceras) serum (Oppel, 1865), Phylloceras (Hypophylloceras) tethys (d'Orbigny, 1841), Phylloceras (Goretophylloceras) liouxense n. sp., Ptychophylloceras (Semisulcatoceras) semisulcatum semisulcatum (d'Orbigny, 1841) et Ptychophylloceras (Semisulcatoceras) semisulcatum (d'Orbigny, 1841) diphyllum (d'Orbigny, 1841). Les espèces Sowerbyceras calypso (d'Orbigny, 1841) et Phyllopachyceras rogersi (Kitchin, 1908) sont représentées par de plus rares spécimens. Les récoltes de la Drôme et l'Ardèche ont permis de compléter nos connaissances sur les faunes valanginiennes du Bassin vocontien. En particulier, c'est le cas pour l'espèce Ptychophylloceras (Semisulcatoceras) semisulcatum semisulcatum (d'Orbigny, 1841) très rare (un seul spécimen identifié à Senez-Lioux) mais plus abondante dans les gisements valanginiens de la Drôme.- SRef-ID: http://overview.sref.org/1634-0744/CG2012_M01.- Handle-ID: http://hdl.handle.net/2042/47505 Memoir carnetsdegeologie@hotmail.com Mon, 17 Sep 2012 13:57:18 GMT http://www.jgeosci.org/issue-57-2 * Petrophysical and geochemical characteristics of late Variscan granites in the Karlovy Vary Massif (Czech Republic) - implications for gravity and magnetic interpretation in shallow depths.- Blecha V & Stemprok M<br /> * Structural evolution of the Roudny gold deposit, Bohemian Massif: a combination of paleostress analysis and review of historical documents.- Zacharias J & Hubst Z<br /> * Evolution of the Early Permian volcanic-plutonic complex in the western part of the Permian Gobi-Altay Rift (Khar Argalant Mts., SW Mongolia).- Burianek D, Hanzl P, Budil P & Gerdes A<br /> * Petrology of the Late Cretaceous peralkaline rhyolites (pantellerite and comendite) from Lake Chad, Central Africa.- Mbowou GIB, Lagmet C, Nomade S, Ngounouno I, Deruelle B & Ohnenstetter D Journal jgeosci@jgeosci.org Sun, 15 Jul 2012 00:00:00 GMT http://paleopolis.rediris.es/cg/CG2012_A06/ Dominique Fortwengler, Didier Marchand, Alain Bonnot, Rémi Jardat & Daniel Raynaud.- Proposal for the Thuoux section as a candidate for the GSSP of the base of the Oxfordian stage.- The Thuoux section, located in South-Eastern Basin of France (coordinates: 44°30'55"E; 5°42'25"N), is a section that satisfies numerous demanding criteria as reference section (GSSP) for the base of the Oxfordian stage. Sedimentation was continuous in that the abundant ammonitic fauna yields no detectable hiatuses. The stratigraphic boundary is located between the Lamberti Zone and the Mariae Zone or more precisely between the Paucicostatum horizon (Marchand, 1979) and the Thuouxensis horizon (Fortwengler & Marchand, 1994a). In this section, there is a perfect mixing between Boreal ammonites (Cardioceratinae) whose species are used as stratigraphic markers and Submediterranean/Subboreal ammonites (Hecticoceratinae, Peltoceratinae and Perisphinctinae) that provide further possibilities for wide correlation of this boundary. Finally, parallel ammonite zonations have been established with great precision (biohorizons and sometimes "sub-biohorizons") in various areas of France, with different palaeoenvironments. The Thuoux section permits correlations with central and eastern Europe as well as North America, based on Cardioceratinae successions, and with South America, using Peltoceratinae. Thickness of the Callovian-Oxfordian transitional beds in the Thuoux section has allowed detailed sedimentological studies and astronomical calibration of the Lower Oxfordian (Boulila, 2008; Boulila et al., 2008). The Thuoux section is located at the centre of a set of more than thirty sections where the base of the Oxfordian stage is visible (Fortwengler, 1989; Fortwengler & Marchand, 1994a, b, c, d). - SRef-ID: http://overview.sref.org/1634-0744/CG2012_A06.- Handle-ID: http://hdl.handle.net/2042/47431 Article carnetsdegeologie@hotmail.com Sat, 14 Jul 2012 13:53:37 GMT http://iopan.gda.pl/oceanologia/54_3.html * Variability of temperature and salinity over the last decade in selected regions of the southern Baltic Sea.- Rak Daniel, Wieczorek Piotr <br /> * Spectral dependence of the correlation between the backscattering coefficient and the volume scattering function measured in the southern Baltic Sea.- Włodzimierz Freda<br /> * A statistical approach to coastal upwelling in the Baltic Sea based on the analysis of satellite data for 1990-2009.- Lehmann Andreas, Myrberg Kai, Höflich Katharina<br /> * Monitoring the effect of upwelling on the chlorophyll a distribution in the Gulf of Finland (Baltic Sea) using remote sensing and in situ data.- Uiboupin Rivo, Laanemets Jaan, Sipelgas Liis, Raag Laura, Lips Inga, Buhhalko Natalia <br /> * Currents and waves in the northern Gulf of Riga: measurement and long-term hindcast:.- Suursaar Ülo, Kullas Tiit , Aps Robert <br /> * Response of eastern Indian Ocean (ODP Site 762B) benthic foraminiferal assemblages to the closure of the Indonesian seaway.- Rai Ajai Kumar, Singh Virendra Bahadur <br /> * Vertical distribution of zooplankton in the epipelagic zone off Sharm El-Sheikh, Red Sea, Egypt:.- Dorgham Mohamed Moussa, Mohamed Elsherbiny Mohsen, Hassan Hanafi Mahnoud <br /> * Mapping an ecosystem service: A quantitative approach to derive fish feeding ground maps.- Šiaulys Andrius, Daunys Darius, Bučas Martynas, Bacevičius Egidijus Journal sabina@iopan.gda.pl Tue, 26 Jun 2012 11:20:55 GMT http://paleopolis.rediris.es/cg/CG2012_A05/ Michel Hennebert.- Hunting for the 405-kyr eccentricity cycle phase at the Cretaceous-Paleogene boundary in the Aïn Settara section (Kalaat Senan, central Tunisia).- The Aïn Settara section (Kalaat Senan, central Tunisia) shows a continuous and well exposed marl-limestone alternation, extending from the Upper Maastrichtian to the basal Danian. The section reveals the superposition of several cycles, which correspond to the combined astro-climatic effect of both eccentricity and precession. Based on the ~100-kyr eccentricity and the ~21-kyr precession cycles, a floating chronometric scale is proposed. Thanks to this scale, the sedimentary and biological events of the section are dated with respect to the Cretaceous-Paleogene (K-Pg) boundary taken as the reference. Highlighting the very stable 405-kyr eccentricity cycle allows on one side to confirm the relevance of the established time scale and on the other side to determine the phase of this important signal with respect to the K-Pg boundary event.- SRef-ID: http://overview.sref.org/1634-0744/CG2012_A05.- Handle-ID: http://hdl.handle.net/2042/47314 Article carnetsdegeologie@hotmail.com Mon, 21 May 2012 13:05:38 GMT http://paleopolis.rediris.es/cg/CG2012_A04/ Nestor J. Sander.- Paleontologic and stratigraphic overview of the Paleogene in eastern Saudi Arabia.- The beds of early Tertiary age in eastern Saudi Arabia are in large part chemical precipitates laid down in a shallow epicontinental sea. The sequence is divided into three formations, each clearly differentiated in both lithology and fauna. From bottom to top they have been named the Umm er Radhuma, Rus and Dammam formations. Ecologic conditions remained more or less uniform for considerable lengths of time. Consequently, the fauna, made up mainly of foraminifera, became well adapted to the environment, as demonstrated by the abundance of some species. The great number of individuals of these species have a range of variability much broader that that seen in other areas of their occurrence.

Its biological affinities have not been fully resolved and phylogenetic links with both annelids and cnidarians have traditionally been suggested. Differences in tube morphology, ultrastructure and biomineralization suggest that Cloudina is not closely related to any recent skeletal annelid (e.g., serpulids, sabellids and cirratulids) and their skeletons are not homologous. The way of asexual reproduction in Cloudina resembles more that of cnidarians. The presence of a closed tube origin (base) in Cloudina is also compatible with the hypothesis of an animal of cnidarian grade.- SRef-ID: http://overview.sref.org/1634-0744/CG2012_A03.- Handle-ID: http://hdl.handle.net/2042/46095 Article carnetsdegeologie@hotmail.com Mon, 12 Mar 2012 09:05:18 GMT http://paleopolis.rediris.es/cg/Nestor_Sander.html Bruno R.C.

Granier.- Manuel de Micropaléontologie.- La micropaléontologie concerne à une division de la paléontologie dont l'objet est l'étude des fossiles de petites dimensions. Ce n'est cependant pas une simple division de la paléontologie, mais un ensemble de sous-disciplines traitant de groupes divers d'organismes qui n'ont en commun que le fait de n'être connus que par des restes fossilisés de petites dimensions. L'outil d'observation le plus communément utilisé est la loupe binoculaire ; il est parfois nécessaire d'avoir accès à de plus forts grossissements et donc de se servir d'un microscope optique, voire d'un microscope électronique à balayage. Ce critère dimensionnel fait que la micropaléontologie s'intéresse aussi bien à des organismes microscopiques unicellulaires qu'à des restes (organites) de grands organismes pluricellulaires. Par définition, la nature organique, minéralogique ou mixte de ces fossiles est extrêmement variée ; de ce fait les approches et techniques d'analyse sont également variables d'un groupe à l'autre. Ces restes peuvent se classer de la façon suivante : les microfossiles (dimensions comprises entre 0,05 mm et quelques mm) ; les nannofossiles (dimensions inférieures à 50 µm) ; les organites ou fragments isolés de macrofossiles reconnaissables à leur forme et/ou leurs caractères microstructuraux. Parmi les groupes concernés par la micropaléontologie figurent de nombreux protozoaires (Foraminifères, Radiolaires), des algues unicellulaires (Dasycladales, Coccolithophoracées, Dinoflagellés, Diatomées), des métazoaires libres (Ostracodes) ou coloniaux (Bryozoaires), des métaphytes (Corallinales, Charophytes), des organites de métaphytes (spores et grains de pollens), des formes dont l'interprétation est incertaine (parmi ces incertae sedis, citons : Acritarches, Calpionelles, Chitinozoaires, Gilianelles, etc.). Remarque : Les représentants fossiles des algues benthiques sont parfois improprement désignés dans le langage vernaculaire par le vocable "algues calcaires", termes qui regroupent des formes aussi distinctes que des Chlorophytes (Dasycladales et Bryopsidales), des Rhodophytes (Corallinales), des Charophytes et des structures biosédimentaires d'origine "microbienne". Quelques formes benthiques non calcifiées sont connues uniquement dans des gisements de type "Fossil-Konservat-Lagerstätten" ; ces préservations exceptionnelles ne sont pas décrites dans ce manuel. Les microfossiles sont des indicateurs paléoécologiques des anciens milieux de vie. Les associations et leur taphonomie permettent de caractériser les sédiments continentaux ou marins et de décrypter les conditions de dépôt. Les microfossiles sont aussi les marqueurs des temps géologiques depuis le Cambrien, voire depuis le Protérozoïque pour les seuls palynomorphes (microfossiles variés à paroi organique). Le découpage micropaléontologique du temps est un outil chronologique de plus en plus précis et en perpétuelle amélioration. Beaucoup (Foraminifères, Coccolithophoracées, Dinoflagellés, Chitinozoaires, etc.) sont les index de biozones des échelles biostratigraphiques de référence pour la datation des couches géologiques. Leur compétitivité tient à leur fréquence élevée et à leur grande diversité dans tous les milieux aquatiques. Les forages d'exploitation pétrolière et les forages scientifiques utilisent en routine les microfossiles pour dater les niveaux traversés. Leur rôle dans la datation des fonds océaniques a été et est encore fondamental. La réalisation des cartes géologiques récentes fait, pour une large part, appel au micropaléontologue.- SRef-ID: http://overview.sref.org/1634-0744/CG2011_B02.- Handle-ID: http://hdl.handle.net/2042/45793 Book carnetsdegeologie@hotmail.com Sun, 25 Dec 2011 15:20:31 GMT http://www.iopan.gda.pl//oceanologia/53_4.html SatBałtyk - A Baltic environmental satellite remote sensing system - an ongoing project in Poland.

This is the first well attested occurrence of Cetiosaurus in France. The presence of Cetiosaurus remains in the Bathonian of both Oxfordshire and the Ardennes is explainable by the fact that these regions were situated on the margin of the London-Brabant Massif land area, on which sauropod populations apparently lived. Contrary to the condition in other sauropods in insular environments, there is no evidence of dwarfism in Cetiosaurus from the London-Brabant Massif, probably because this emergent area was connected to the much larger Fenno-Scandian Shield.- SRef-ID: http://overview.sref.org/1634-0744/CG2011_L06.- Handle-ID: http://hdl.handle.net/2042/43897 Letter carnetsdegeologie@hotmail.com Mon, 10 Oct 2011 18:07:13 GMT http://paleopolis.rediris.es/cg/CG2011_L05/ Olev Vinn & Elena K.

Some of these layers are made of densely packed large crystals and others are composed of sparsely packed fine crystals. In almost all (16 of 17) examined species having layered tubes, the dense layer is located in the outer wall part and the layer(s) composed of fine and relatively sparsely packed crystals are positioned in the inner wall part. Two species have transparent tube walls made entirely of densely packed crystals. Fossil serpulid tubes with dense outer layers (DOL) are known from the Late Cretaceous (Pentaditrupa subtorquata) and the Eocene (Pyrgopolon cf. mellevillei and Rotularia spirulaea). DOL gives a characteristic smooth shiny appearance to the tube surface and presumably evolved as an adaptation against drilling predation by gastropods and to delay shell dissolution in the waters of the deep-sea under-saturated with calcium carbonate.- SRef-ID: http://overview.sref.org/1634-0744/CG2011_L05.- Handle-ID: http://hdl.handle.net/2042/43896 Letter carnetsdegeologie@hotmail.com Mon, 10 Oct 2011 18:02:45 GMT http://paleopolis.rediris.es/cg/CG2011_L04/ Robert Busnardo & Bruno R.C.

After deposition, the CPX have been increasingly altered by longer exposures. Weathering of brown CPX yields paler minerals which are greenish-brown, colourless or two-coloured. Similarly, the CPX found in the Seine basin are from recent volcanic ash or old Sologne deposits, and not from Loire alluvial deposits, so that a Pleistocene palaeo-Loire-Seine river is improbable.- SRef-ID: http://overview.sref.org/1634-0744/CG2011_L03.- Handle-ID: http://hdl.handle.net/2042/43894 Letter carnetsdegeologie@hotmail.com Mon, 10 Oct 2011 18:21:01 GMT http://paleopolis.rediris.es/cg/CG2011_B03/ Loïc Costeur & Martin Schneider.- Catalogue of the Eocene mammal types of the Natural History Museum Basel.- This catalogue presents a list of the Eocene mammalian type specimens held in the collection of the Natural History Museum Basel (Naturhistorisches Museum Basel, hereafter NMB).

This method of investigation facilitates greatly the identification of the external and internal features of each species.- SRef-ID: http://overview.sref.org/1634-0744/CG2011_SP01.- Handle-ID: http://hdl.handle.net/2042/43105 Special Publication carnetsdegeologie@hotmail.com Wed, 20 Jul 2011 19:04:01 GMT http://www.jgeosci.org/index.php?pg=issue&vol=56&iss=2 * Journal of Geosciences gains an impact factor!.- Janousek V<br /> * Geophysical and structural pattern of the Knizeci Stolec pluton and its host rocks in the south-western part of the Moldanubian Zone, Bohemian Massif.- Sedlak J, Gnojek I, Verner K, Franek J, Zabadal S, Motschka K & Slovak J<br /> * Variable eruptive styles in an ancient monogenetic volcanic field: examples from the Permian Levin Volcanic Field (Krkonose Piedmont Basin, Bohemian Massif).- Starkova M, Rapprich V & Breitkreuz Ch<br /> * Petrology and monazite dating of the Fe-rich gneisses from Kokava (Veporic Unit, Western Carpathians, Slovakia): Devonian sediments supplied from Gondwanan-sources metamorphosed in the Variscan times.- Konecny P, Kohut M, Rojkovic I & Siman P<br /> * Pegmatite dykes and quartz veins with tourmaline: an example of partial melting in the contact aureole of the Chandman Massif intrusion, SW Mongolia.- Burianek D, Hanzl P & Hrdlickova K<br /> * Plimerite from Krasno near Horni Slavkov ore district, Czech Republic.- Sejkora J, Plasil J & Filip J Journal jgeosci@jgeosci.org Fri, 15 Jul 2011 00:00:00 GMT http://paleopolis.rediris.es/cg/CG2011_A04/ Fateh Mebrouk, Jean-Paul Colin & Fatima Hennache.- Un gisement d'ostracodes non-marins dans l'Éocène inférieur du Djebel Amour, Atlas saharien central, Algérie : taxonomie, paléoécologie et paléobiogéographie.- Un gisement bien daté par une riche microflore de charophytes caractéristique de la zone à Peckichara disermas, de l'Éocène inférieur (Yprésien inférieur = Sparnacien = Ilerdien) a livré une intéressante association d'ostracodes non-marins dans le Djebel Amour, Atlas Saharien occidental, en Algérie. Cette faune est caractérisée par la dominance du genre Neocyprideis avec l'espèce nouvelle Neocyprideis meguerchiensis nov. sp. et la présence occasionnelle des genres Hemicyprideis, Perissocytheridea (P. algeriensis nov. sp.) et Limnocythere. Il s'agit de la seconde découverte du genre Neocyprideis dans le Paléogène du continent africain, la première étant dans l'Éocène inférieur du Sénégal. Les Neocyprideis sont représentés à 75 % par des formes lisses, normalement calcifiées, à 20 % par des individus réticulés et tuberculés et à 5 % par des spécimens uniquement réticulés. Ce polymorphisme suggère une saisonnalité marquée avec une salinité variable. La dominance des morphes lisses bien calcifiés indique un milieu avec un équilibre entre le Ca++ et le Mg++, les morphes réticulés caractérisant un milieu plus riche en Mg++. La présence de forme tuberculées-réticulées suggère des apports saisonniers organo-siliceux continentaux et une salinité pouvant temporairement atteindre des valeurs inférieures ou égales à 5 psu.- SRef-ID: http://overview.sref.org/1634-0744/CG2011_A04.- Handle-ID: http://hdl.handle.net/2042/42328 Article carnetsdegeologie@hotmail.com Tue, 05 Jul 2011 18:46:37 GMT http://paleopolis.rediris.es/cg/CG2011_A03/ Chahira Zaîbi, Fekri Kamoun, Pierre Carbonel & Mabrouk Montacer.- Distribution des ostracodes dans les sédiments de subsurface de la Sebkha El-Guettiate (Skhira, golfe de Gabès). Intérêt pour la reconstitution des paléo-environnements de l'Holocène.- L'étude quantitative et qualitative des ostracodes des carottes SG1 et BSC2, prélevées au niveau de la Sebkha El-Guettiate de Skhira (Sud - Est Tunisien), nous a permis de reconnaître les trois associations suivantes : (1) association de milieu marin s.l. composée de Aurila prasina Barbieto-Gonzalez, 1971, Cushmanidea elongata (Brady, 1868), Urocythereis oblonga (Brady, 1866), U. favosa (Roemer, 1838) (marin côtier), Basselerites berchoni (Brady, 1869), Semicytherura incongruens (G.W. Müller, 1894), S. paradoxa (G.W. Müller, 1894), S. sella (Sars, 1866), S. ruggierii (Pucci, 1955), Carinocythereis carinata (Roemer, 1838) et Paracytheridea depressa (G.W. Müller, 1894) (marin ouvert) ; (2) association de milieu lagunaire, à salinité variable, constituée, de Xestoleberis aurantia (Baird, 1838), Leptocythere fabaeformis (G.W. Müller, 1894) et Cytherois fischeri (Sars, 1866), (3) association de milieu saumâtre estuarien où se développent Cyprideis torosa (Jones, 1850) et Loxoconcha elliptica Brady, 1868. Ces associations révèlent les caractéristiques des paléo-environnements qui se sont succédés, au cours de l'Holocène supérieur, à l'emplacement de la Sebkha El-Guettiate. Trois phases peuvent être reconnues : i) la première phase à caractère lagunaire estuarien dominant (6595 ± 120 à 6055 ± 30 ans B.P.) comprend un environnement lagunaire ouvert riche en ostracodes marins dominants évoluant brutalement vers un environnement lagunaire estuarien. Ce dernier est caractérisé par un évènement de haute énergie, vers 6595 ± 120 ans B.P., révélé par des apports détritiques riches en galets, synchrones à l'enrichissement des ostracodes saumâtres. Ensuite, une lagune s'installe vers 6055 ± 30 ans B.P. permettant le développement des ostracodes principalement saumâtres dominants mais aussi lagunaires. ii) la phase suivante (6055 ± 120 à 5150 ± 50 ans B.P.) se distingue par la réapparition des taxons marins associés aux espèces lagunaires et saumâtres traduisant une lagune estuarienne largement ouverte soumise à l'influence des courants de dérive littorale. Ces courants, en édifiant des cordons littoraux, ont entraîné la fermeture du milieu et la fin de la dominance des ostracodes saumâtres. iii) la dernière phase (5150 ± 50 ans B.P. à l'actuel) comprend un milieu caractérisé par la richesse des taxons lagunaires évoluant vers un milieu laguno-saumâtre recevant le dépôt de washover suite à un événement climatique extrême. La lagune, de plus en plus fermée, évoluera progressivement vers la sebkha actuelle.- SRef-ID: http://overview.sref.org/1634-0744/CG2011_A03.- Handle-ID: http://hdl.handle.net/2042/42327 Article carnetsdegeologie@hotmail.com Tue, 05 Jul 2011 18:50:23 GMT http://paleopolis.rediris.es/cg/CG2011_L02/ Adeline Kerner, Régine Vignes Lebbe & Françoise Debrenne.- Computer-aided identification of the Archaeocyatha genera now available online.- The Archaeocyatha are a key group in several of the many discrete disciplines that together make feasible a valid history of the Earth: they are the oldest of the calcified sponges, the first metazoans to build reefs (in association with calcimicrobes), are characteristic fossils used for the biozonation of the first, pre-trilobitic Cambrian stage (Tommotian)… To date, a valid key to their identification has not been available, so a tool for that purpose has been devised: it was created using the software XPER2, and is now available free, online.

Seule la coupe de Pamproux (située sur le site de l'usine Pampr'oeuf), dont la Zone à Plicatilis n'est représentée que par la Sous-zone à Antecedens, est étudiée dans le détail. Les collectes ont été effectuées in situ et dans les déblais constitués uniquement de marnes attribuées à la Sous-zone à Antecedens. Le lavage des sédiments a permis de collecter un très grand nombre de fossiles très diversifiés et de tailles extrêmement réduites. C'est ainsi que furent découverts un grand nombre d'individus appartenant à deux nouvelles espèces de Taramelliceratinae, ainsi que deux nouvelles espèces de Glochiceras, de taille adulte bien différentes, ressemblant à s'y méprendre à Ochetoceras (Ochetoceras) canaliculatum (von Buch, 1831) morphe subclausum [m] Oppel, 1863.

On note que les âges obtenus sont souvent rajeunis indépendamment du site, du taux de calcite, de la teneur en uranium et du rapport 234U/238U. Contrairement aux échantillons de coraux, le critère minéralogique ne peut pas être utilisé pour choisir les échantillons non recristallisés, certaines coquilles de mollusques actuelles sont en aragonite, d'autres sont en calcite et d'autres contiennent les deux formes sans que les rapports de proportion en soient encore bien connus. Devant cette situation, nous avons multiplié les analyses sur des échantillons de coquilles de mollusques appartenant à plusieurs espèces prélevés aux mêmes endroits afin de comprendre le scénario de rajeunissement des âges et d'essayer d'établir éventuellement des critères méthodologiques pouvant nous renseigner sur la validité de l'âge calculé.

But spherulitic prismatic structures found in the innermost part of the tube wall of Recent Crucigera websteri, C. zygophora, Floriprotis sabiuraensis, and Pyrgopolon ctenactis indicate that the structure grew toward the organic inner tube lining and also toward the tube‘s lumen. Similar directions of growth for this structure are seen in Hydroides sp. from the Miocene of Austria. Growth towards the tube's lumen is opposite to what one would expect if the organic inner tube lining is being used as a scaffold for the biomineralization of CaCO3.- SRef-ID: http://overview.sref.org/1634-0744/CG2011_L01.- Handle-ID: http://hdl.handle.net/2042/38798 Letter carnetsdegeologie@hotmail.com Tue, 15 Mar 2011 19:22:52 GMT http://www.geology.cz/bulletin/contents/2011/vol86no1 * <i>Beloceras</i>, the most multilobate Late Devonian ammonoid.- Korn D, Bockwinkel J, Ebbinghausen V & Walton SA<br /> * Silurian <i>Tetinka</i> Barrande, 1881 (Bivalvia, <i>Spanilidae</i>) from Bohemia (Prague Basin) and Germany (Elbersreuth, Frankenwald).- Kriz J<br /> * Silurian rugose corals from the Kurosegawa Terrane, Southwest Japan, and their paleobiogeographic implications.- Kido E & Sugiyama T<br /> * Earliest occurrence of the <I>Hirnantia </I>Fauna in the Prague Basin (Czech Republic).- Mergl M<br /> * Devonian rhynchonellid brachiopods from the Ougarta area (western Sahara, Algeria).- Brice D, Boumendjel K, Racheboeuf PR & Mottequin B<br /> * Colour pattern polymorphism in Silurian nautiloid <i>Phragmoceras </i>Broderip, 1839.- Turek V & Manda S<br /> * <i>Goniatites</i> Zone (middle Mississippian) ammonoids of the Antler Foreland Basin (Nevada, Utah).- Korn D & Titus AL Journal admin.bulletin@geology.cz Fri, 11 Mar 2011 01:00:00 GMT http://paleopolis.rediris.es/cg/CG2011_A01/ Didier Bert, Gérard Delanoy & Stéphane Bersac.- The Dichotomus Horizon: proposal for a new biochronologic unit of the Giraudi Zone of the Upper Barremian of southeastern France, and considerations regarding the genus Imerites Rouchadzé (Ammonoidea, Gassendiceratinae).- Recent revisions of the genus Imerites Rouchadzé make it possible to introduce a new biochronologic horizon to define more precisely the lower boundary of the Giraudi Zone: the Dichotomus Horizon. Using the concept of 'interval zone', this new horizon maintains the current lower boundary of the Giraudi Zone as accepted by authors, and thus contributes to the stabilization of the Barremian zonal system. This stabilization is also strengthened by abandonment of the use of "Crioceras" cristatus d'Orbigny (nomen dubium) that ought not be used as an index species in detriment of Imerites giraudi (Kilian).
