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. Kupriyanova.- Evolution of a dense outer protective tube layer in serpulids (Polychaeta, Annelida).- Although the walls of most serpulid tubes are homogeneous, tubes of certain species may contain up to four ultrastructurally distinct layers. 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. Granier.- Aptian ammonites of Abu Dhabi (United Arab Emirates).- The identification of some twenty ammonite fragments from oil wells drilled in offshore Abu Dhabi revealed the presence of six Aptian genera: Cheloniceras, Epicheloniceras, Gargasiceras, Colombiceras, Pseudohaploceras, and Macroscaphites. These ammonites indicate the Furcata Zone and the succeeding Martini Zone.

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).

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.

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. Des scénarios sur le mode d'incorporation de l'uranium et son rôle dans le rajeunissement de l'âge ont été également imaginés et discutés.- SRef-ID: http://overview.sref.org/1634-0744/CG2011_A02.- Handle-ID: http://hdl.handle.net/2042/39245 Article carnetsdegeologie@hotmail.com Wed, 27 Apr 2011 19:12:53 GMT http://iopan.gda.pl/oceanologia/53_1.html Seasonal variability in the optical properties of Baltic aerosols .- Zdun Agnieszka , Rozwadowska Anna , Kratzer Susanne <br /> Flow, waves and water exchange in the Suur Strait, Gulf of Riga, in 2008.- Raudsepp Urmas, LaanemetsJaan, Haran Getli, Alari Victor, Pavelson Juss, Kõuts Tarmo <br /> Meteorological influences on the surface hydrographic patterns of the North Aegean Sea:.- Sylaios Georgios<br /> Changes in Atlantic Water characteristics in the south-eastern Mediterranean Sea as a result of natural and anthropogenic activities .- A.

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). The classification, origin, and intraspecific variation of the genus Imerites Rouchadzé are examined.- SRef-ID: http://overview.sref.org/1634-0744/CG2011_A01.- Handle-ID: http://hdl.handle.net/2042/36091 Article carnetsdegeologie@hotmail.com Mon, 17 Jan 2011 14:14:25 GMT http://www.jgeosci.org/index.php?pg=issue&vol=55&iss=4 * Comparison of lithology and tectonometamorphic evolution of units at the northern margin of the Moldanubian Zone: implications for geodynamic evolution in the northeastern part of the Bohemian Massif .- Pertoldova J, Verner K, Vrana S, Burianek D, Stedra V & Vondrovic L<br /> * Remnants of Early Carboniferous I-type granodiorite plutons in the Bavarian Forest and their bearing on the tectonic interpretation of the south-western sector of the Bohemian Massif (Bavarian Zone).- Finger F, Dunkley DJ & Rene M<br /> * Geophysical research on structure of partly eroded maar volcanoes: Miocene Hnojnice and Oligocene Rychnov volcanoes (northern Czech Republic).- Skacelova Z, Rapprich V, Valenta J, Hartvich F, Sramek J, Radon M, Gazdova R, Novakova L, Kolinsky P & Pecskay Z<br /> * The nature of "quartz eyes" hosted by dykes associated with Au-Bi-As-Cu, Mo-Cu, and Base-metal-Au-Ag mineral occurrences in the Mountain Freegold region (Dawson Range), Yukon, Canada.- Bineli Betsi T & Lentz DR<br /> * Burd Gol Granite Massif as a typical product of the Late Cambrian post-orogenic magmatism in the SE part of the Lake Zone, Gobi Altay, SW Mongolia.- Hrdlickova K, Gerdes A, Gilikova H, Bat-Ulzii D & Hanzl P Journal jgeosci@jgeosci.org Sat, 15 Jan 2011 00:00:00 GMT
