Christian C. Emig.- Nummulus brattenburgensis and Crania craniolaris (Brachiopoda, Craniidae).- The Brattingsborg pennies are mentioned in medieval texts dating from the middle of the first millennium and many popular medieval legends refer to their occurrence on Ivö Island in the Scania region (Sweden) as brattingsborgpenningar or in Latin as Nummulus brattenburgensis. Actually they are valves of the fossil brachiopod Crania craniolaris originally described by Linnaeus (1758) as Anomia craniolaris from the Upper Cretaceous. Later Retzius (1781) created the genus Crania based on these specimens from Ivö Island and on another species he described under Crania (now Isocrania) egnabergensis from Ignaberga in the Scania region. The scientific history of those two species is reviewed along with that of Danocrania tuberculata (Nilsson, 1826), formerly figured as Craniolites brattenburgicus, from the Danian of Scania. Two legends about these "pennies" are included.- SRef-ID: http://overview.sref.org/1634-0744/CG2009_A08.- Handle-ID: http://hdl.handle.net/2042/**** |

Bruno R.C. Granier & Christian Staffelbach.- Quick look cathodoluminescence analyses and their impact on the interpretation of carbonate reservoirs. Case study of mid-Jurassic oolitic reservoirs in the Paris Basin.- Cathodoluminescence analyses on samples from Middle Jurassic oolitic limestones allow us to reconstruct the diagenetic history of these oil and gas reservoirs: a succession of events starting with the early, synsedimentary phases of marine cementation and ending with the addition of hydrocarbons to the reservoir. Constraints on the timing of events are derived from their calibration with the chronology of the well-known regional tectonic calendar. Fracturing, due first to the post-Pyrenean extension and then to the Alpine compression, led respectively in Oligocene times to a recharge of the aquifer and a correlative change in cementation, and in Miocene times to the addition of hydrocarbons into the same flow units, this last event blocking diagenesis, at least in the zone above the oil-water contact. Distributions of cements and residual porosity within sedimentary units without stratigraphic significance, called here "pseudo-parasequences", were for the most part inherited from the original depositional facies.- SRef-ID: http://overview.sref.org/1634-0744/CG2009_A07.- Handle-ID: http://hdl.handle.net/2042/28795 |

Lukas Hottinger.- The Paleocene and earliest Eocene foraminiferal Family Miscellaneidae: neither nummulitids nor rotaliids.- The Miscellaneidae are divided into two groups of species: forms with a single intercameral foramen and forms with two or a row of multiple foramina. Ten taxa ascribed to this family are revised, amply illustrated and discussed considering both micro- and megalospheric generations. The Family Miscellaneidae is assigned to the Superfamily Nonionacea by reason of their planispiral-involute coiling combined with an interiomarginal position of the foramina. Their combined range covers SBZ zones 2-5 and an area comprising the Central and Western Neotethys including the Pyrenean Gulf. They do not reach the western shores of the Atlantic. Miscellanites meandrinus and Bolkarina aksarayi exhibit extreme morphological features, respectively meandrine alar extensions and expanse chambers. These features are of general interest for the comparative anatomy of the shells of the larger foraminifera in order to understand their biological significance.- SRef-ID: http://overview.sref.org/1634-0744/CG2009_A06.- Handle-ID: http://hdl.handle.net/2042/28794 |

Philippe Quereilhac, Didier Marchand, Rémi Jardat, Alain Bonnot, Dominique Fortwengler & Philippe Courville.- La faune ammonitique des marnes à fossiles ferrugineux de la région de Niort, France (Oxfordien inférieur, Zone à Cordatum, Sous-Zone à Cordatum).- The ammonite fauna of the 'marls with ferruginous fossils' from the Niort region, France (Lower Oxfordian, Cordatum Zone, Cordatum Subzone).- A new collection of ammonites from the 'marls with ferruginous ammonites' in the Niort region (France), previously studied by Grossouvre (1922), provides a large amount of biostratigraphic, paleoenvironmental and paleogeographic information. The fauna is dated Early Oxfordian: Cordatum Zone, Cordatum Subzone, probably the lower part of it. In addition, it is unique in western Europe owing to: 1) the species found of which some appear to be known only in this deposit 2) by the extremely atypical domination of the couple Taramelliceras - Creniceras which represent 2/3 of the specimens. Furthermore, the aspect of the fauna strongly suggests that the habitat was a distal platform unknown in other European strata of the same age. A detailed description of the several species is given, sometimes accompanied by a new taxonomic interpretation.- SRef-ID: http://overview.sref.org/1634-0744/CG2009_A05.- Handle-ID: http://hdl.handle.net/2042/28697 |

Philippe Quereilhac.- La Sous-Famille des Taramelliceratinae (Ammonitina, Haploceratoidea, Oppeliidae) de l'Oxfordien moyen et supérieur (Zone à Plicatilis, Sous-Zone à Vertebrale - Zone à Bimammatum, Sous-Zone à Berrense) du Nord de la Vienne, France (Province subméditerranéenne).- Subfamily Taramelliceratinae (Ammonitina, Haploceratoidea, Oppeliidae) from Middle and Upper Oxfordian strata (Plicatilis Zone, Vertebrale Subzone - Bimammatum Zone, Berrense Subzone) of N Vienne, France (submediterranean province).- In the area of northern Poitou studied Taramelliceratinae are present at every level except in the Schilli Subzone, itself possibly absent, and the Stenocycloides Subzone in which only Perisphinctidae and Trimarginites sp. occur. Although some species are known and cited in the literature often, they are figured infrequently or not at all: Taramelliceras (Taramelliceras) dentostriatum (Quenstedt), T. (T.) callicerum (Oppel), T. (Proscaphites) anar (Oppel). Here, the ranges of these species in the stratigraphic succession were determined through their association with other faunas in the same collections, using the presence or absence of known precise stratigraphic markers (for example: Neomorphoceras chapuisi (Oppel) = Transversarium Zone, Luciaeformis Subzone ; Taramelliceras (? Taramelliceras) colleti (Lee) = Rotoides Subzone ; "Epipeltoceras semimammatum" (Quenstedt) = Bimammatum Zone, "Berrense" Subzone, Semimammatum horizon) and/or the disappearance of species with longer ranges (for example: the disappearance of Neoprionoceras lautlingensis (Rollier) which is present in the Parandieri Subzone, but absent in the overlying Luciaeformis Subzone). The ranges of certain species that had been incorrectly located stratigraphically : T. (T.) dentostriatum (Quenstedt), T. (T.) callicerum (Oppel), T. (T.) externnodosum Dorn, have been restored to their true location as determined from their occurrences in the author's collections and in those of other collectors who had noted their stratigraphic relationships to other taxa. |

Eric Buffetaut.- An additional hadrosaurid specimen (Dinosauria: Ornithischia) from the marine Maastrichtian deposits of the Maastricht area.- An isolated dinosaur vertebra from the marine deposits of the Maastrichtian type area, near the city of Maastricht (The Netherlands), collected during the 19th century and kept in the palaeontological collection of the Museum für Naturkunde in Berlin, is described as a caudal vertebra of a hadrosaurid ornithopod. Although it cannot be identified with greater accuracy, this specimen is an addition to the still scanty, but growing, record of non-avian dinosaurs from the Maastrichtian type area. This record is heavily dominated by hadrosaurs, which probably reflects a real abundance of this group of dinosaurs in the Late Maastrichtian of Europe.- SRef-ID: http://overview.sref.org/1634-0744/CG2009_L03.- Handle-ID: http://hdl.handle.net/2042/28153 |
