Josep A. Moreno-Bedmar & Keith P. Minor.- Review of some Aptian ammonites collected by Gaston Astre in Lleida Province, Catalonia, Spain.- We study the three best preserved ammonites collected by Astre in 1924-1925 in Lleida Province, Catalonia, Spain, in order to assess their taxonomic assignment. We also include images of these ammonoids since they were not illustrated in Astre's original 1934 work. This taxonomic review allows us to identify these lower Aptian ammonites as Pseudohaploceras liptoviense, Deshayesites sp. and Dufrenoyia sp.- Handle-ID: http://hdl.handle.net/2042/56911

Badre Essafraoui, Serge Ferry, Danièle Groshény, Nourrisaid Içame, Hassan El Aouli, Moussa Masrour, Luc G. Bulot, Yves Géraud & Mohamed Aoutem.- Sequence stratigraphic architecture of marine to fluvial deposits across a passive margin (Cenomanian, Atlantic margin, Morocco, Agadir transect).- Seven sections, covering the upper Albian to lowermost Turonian, have been correlated from full-marine to continental-dominated deposits across a passive margin, along a transect 425 km long, from the present-day Atlantic coast to the "Pre-African Trough" between the Anti-Atlas and the High-Atlas. The thickness of the Cenomanian succession changes from around 500 metres in the fully marine sections to 250 metres in mostly continental facies in the western High-Atlas, about 150 km updip, to a few tens of metres in the Bou Tazoult area. The strata thicken again eastwards into the Pre-African Trough where they can be traced without major facies changes to the Kem Kem embayment and to the Bechar area in Algeria. Over all this eastern area, continental facies are overlain by the fully-marine shallow-water deposits of the Cenomanian-Turonian boundary interval. A first major conclusion is that fluvial aggradation in high-frequency transgressive-regressive sequences is coeval with the seaward-shift of the shoreline, in accordance with the genetic sequence stratigraphic model of Galloway (1989). Both the flatness of the depositional profile and the corresponding very low energy of the marine environment during the transgressions account for the blanket of red continental clays on top of marine facies in updip depositional sequences, which is then preserved under the marine transgressive surface of the next sequence. A second major conclusion is that the high-frequency transgressive-regressive (T-R) sequences do not look like classical parasequences bounded by transgression surfaces. They usually exhibit a surface created by a sea-level fall within the regressive half-cycle. This is interpreted in the following way: regressions did not operate through a regular seaward-shift of the shoreline, but through stepped sea-level falls. The very low slope of the depositional ramp is thought to have enhanced the sequence stratigraphic record of such stepped regressions. Short-term, high-frequency sequences are organized into medium-frequency T-R sequences (seven in the Cenomanian) which show an overall aggrading and slowly retrograding pattern along the whole transect. Comparisons with other basins show that medium-frequency sequences do not fit the third-order depositional sequences described elsewhere, casting doubts about a eustatic mechanism for their deposition.- Handle-ID: http://hdl.handle.net/2042/56909

Bruno Granier & Dimas Dias-Brito.- End of a modern geological myth: there are no rudists in Brazil! Paleobiogeographic implications.- Out of the few records of rudists from the Cretaceous strata of the South Atlantic coastal basins only two refer to Brazilian localities. However, petrographic analyses demonstrate that these shells should be assigned to Ostreids or to Pycnodontids rather than to Rudistids. More specifically, the domain considered herein, north of the Río Grande Rise - Walvis Ridge barrier, was part of the warm-water "tropical" realm, but it was not part of the Mesogean domain because both Rudistids and Orbitolinas are missing. In addition, the scarcity of corals leads us to ascribe the taphonomic assemblage to the Chloralgal facies. Neither generalized hypersalinity or extreme sea-water temperatures seem to account for these biotic peculiarities. Instead, our alternative hypothesis favors the driving role played by oceanic circulation in the dispersal of the benthic organisms.- Handle-ID: http://hdl.handle.net/2042/56880

Jayagopal Madhavaraju, Robert W. Scott, Yong Il Lee, Kunjukrishnan Sathy Bincy, Carlos M. González-León & Sooriamuthu Ramasamy.- Facies, biostratigraphy, diagenesis, and depositional environments of Lower Cretaceous strata, Sierra San José section, Sonora (Mexico).- We used petrofacies analysis, carbon, oxygen and strontium isotope data to interpret the isotopic variations in the carbonate rocks of the Mural Formation of Sonora (Sierra San José section), Mexico. The petrographic study reveals a range of lithofacies from wackestone to packstone. The analyzed limestones show significant negative ?18O values (-18.6 to -10.9 VPDB) and ?13C values ranging from negative to positive (-2.6 to +2.5? VPDB). The absence of correlation between ?13C and ?18O values suggests a primary marine origin for the ?13C values of limestones from the Sierra San José section. The limestones have large variations in 87Sr/86Sr values (0.707479 to 0.708790). Higher 87Sr/86Sr ratios in various levels of the studied section suggest that most of the sediments were derived from the Proterozoic basement of the Caborca block during Early Cretaceous time. A decrease in 87Sr/86Sr ratios at certain levels indicates an influx of lesser amounts of radiogenic Sr that could have been caused by contribution of sediments from the Triassic and Jurassic volcanic rocks.- Handle-ID: http://hdl.handle.net/2042/56879

Laibl, Thierry Oudoire, Marika Polechová & Lucie Fatková.- Cambrian fossils from the Barrandian area (Czech Republic) stored in the Musée d'Histoire Naturelle de Lille.- A complete list of fossils originating from the Cambrian of the Barrandian area and housed in the Musée d'Histoire Naturelle de Lille is compiled. The collection includes two agnostids, ten trilobites, one brachiopod and one echinoderm species, all collected at ten outcrops in the Buchava Formation of the Skryje-Tý?ovice Basin and most probably also at two outcrops in the Jince Formation of the P?íbram-Jince Basin. A large part of the material was collected by Prof. Charles Barrois and Dr. Louis Dollé (both University of Lille) during the excursion organised before the Ninth International Geological Congress in Vienna in 1903. Other, poorly documented specimens were purchased from the enterprise Krantz towards the end of the 19th century and in the first years of 20th century. The geographic position and stratigraphy of outcrops, from which the material originates, are briefly discussed.- Handle-ID: http://hdl.handle.net/2042/56878

Miguel Company & José M. Tavera.- Lower Valanginian ammonite biostratigraphy in the Subbetic Domain (Betic Cordillera, southeastern Spain).- A new zonation for the lower Valanginian in the Betic Cordillera is presented. It is based on the study of 16 sections located near Caravaca and Cehegín (Region of Murcia). From bottom to top, the following interval zones, defined by the first appearance of the index-species, are distinguished: * "Thurmanniceras" pertransiens Zone, which can be subdivided into two subzones, a lower "Th." pertransiens Subzone and an upper Vergoliceras salinarium Subzone. The latter is characterized by the disappearance of Olcostephanus drumensis and the appearance of Luppovella superba. * Neocomites neocomiensiformis Zone, also with two subzones, the Baronnites hirsutus Subzone below (characterized by the appearance of "Busnardoites" subcampylotoxus and Olcostephanus guebhardi) and the Valanginites dolioliformis Subzone above ("Busnardoites" campylotoxus is restricted to this subzone). * Karakaschiceras inostranzewi Zone, subdivided as well into two subzones, a lower Karakaschiceras inostranzewi Subzone and an upper Saynoceras contestanum Subzone. The assemblages characterizing each of these biozones can be recognized throughout the Mediterranean region.- Handle-ID: http://hdl.handle.net/2042/56745

Olev Vinn & Ursula Toom.- Some encrusted hardgrounds from the Ordovician of Estonia (Baltica).- The Ordovician hardground faunas of Estonia are not diverse. They include echinoderm holdfasts (i.e., eocrinoids and crinoids), edrioasteroids, bryozoans (both hemispherical trepostomes and stalked ptilodictyids) and cornulitids. The earliest hardground faunas appeared in the Dapingian (i.e., bryozoans and echinoderms). The Estonian hardground faunas are less diverse than the North American ones. North American hardgrounds seem to be more heavily encrusted than the Estonian ones. These differences may be due to the paleogeographic distances, different climates and different sedimentation environments of the paleocontinents.- Handle-ID: http://hdl.handle.net/2042/56744

Andreas May.- MayLib - a textfile-based bibliographic database for geosciences and a list of references on Devonian matters.- Scientists need to manage their own collections of bibliographic data as well as exchange these data easily with colleagues. One solution for this need is MayLib, a bibliographic database that runs on many different operating systems and does not require pre-installation of any software. MayLib is a very small, efficient and comprehensive JAVA program that handles references to publications in any Unicode-compatible language. It is user-friendly and not only contains the basic functions of a bibliographic database, but also has some advanced features. Using MayLib the author has been able to create a list of references, which contains 500 periodicals and 4206 literature references. Of these 4206 references 3191 deal with Devonian matters and 1594 references deal with corals.- Handle-ID: http://hdl.handle.net/2042/56481

Francesco Sciuto, Antonietta Rosso, Rossana Sanfilippo & Rosanna Maniscalco.- New faunistic data on the Pleistocene environmental evolution of the south-western edge of the Hyblean Plateau (SE Sicily).- Faunistic associations of the Lower Pleistocene sediments, out-cropping at Cartiera Molino along the true right bank of the Ippari River (Vittoria, SE Sicily), have been investigated. This study integrates data obtained from the analysis of ostracods, foraminifers, bryozoans and serpulids found within a six metre thick sedimentary section. This multiproxy approach allowed us to reconstruct the palaeoenvironmental evolution of this south-western sector of the Hyblean Plateau (Comiso-Vittoria area) from fluvially-influenced shallow marine settings, recorded in the lower portion of the succession, to progressively shallower, transitional and brackish environments, testified in mid levels, up to freshwater environments at the top of the section.- Handle-ID: http://hdl.handle.net/2042/56401

Simon F. Mitchell.- A reassessment of the validity and affinities of Belemnites sulcatus Miller, 1826, Belemnopsis Edwards in Gray, 1849, and Belemnopsis Bayle, 1878.- A reinvestigation of the validity of the belemnite genus Belemnopsis Bayle is undertaken, together with a survey of the early history of the usage of the names Belemnites sulcatus, Belemnopsis Bayle and Belemnopsis Edwards. Belemnites sulcatus Miller has been variously equated with either Belemnites apiciconus Blainville or with the group of belemnites including Belemnites Altdorfensis Blainville and B. Beaumontianus Orbigny. Riegraf (and not Phillips) subsequently designated a lectotype which may be valid and, in case it is not, is validated here. The species concept for Belemnites sulcatus, as based on this lectotype, places it in the genus Holcobeloides Gustomesov. Belemnopsis Edwards has date priority over Belemnopsis Bayle, but must be interpreted as an "incorrect original spelling" and, therefore, does not enter into homonymy according to the ICZN; Belemnopsis Bayle is thus a valid genus. Douvillé subsequently nominated Belemnites sulcatus, which was figured as Belemnopsis sulcata by Bayle, and therefore is a valid designation because this species is amongst the original species included in Belemnopsis by Bayle. One of Bayle's figures of Belemnopsis sulcata agrees with Belemnites apiciconus Blainville, but does not agree with Belemnites sulcatus as defined by its lectotype; as such this is a case of misidentified type species. Belemnites apiciconus Blainville, the species involved in the misidentification, is therefore designated type species of Belemnopsis Bayle here and validated by citing the ICZN. The actions taken here maintain nomenclature at the genus, family and suborder level in respect to the names Belemnopsis and Belemnosis and serve to stabilize the complicated nomenclature issues related to these taxa.- Handle-ID: http://hdl.handle.net/2042/56399

Jean-Pierre Masse, Sibelle Maksoud, Mukerrem Fenerci-Masse, Bruno Granier & Dany Azar.- Earliest Aptian Caprinidae (Bivalvia, Hippuritida) from Lebanon.- The presence in Lebanon of Offneria murgensis and Offneria nicolinae, two characteristic components of the Early Aptian Arabo-African rudist faunas, fills a distributional gap of the corresponding assemblage between the Arabic and African occurrences, on the one hand, and the Apulian occurrences, on the other hand. This fauna bears out the palaeogeographic placement of Lebanon on the southern Mediterranean Tethys margin established by palaeostructural reconstructions. The associated micropaleontological elements suggest an earliest Aptian age (early Bedoulian) for the Offneria murgensis - O. nicolinae assemblage found in the "Falaise de Blanche" stratigraphic interval, instead of a late Early Aptian age as proposed for most of the peri-Adriatic and Middle East occurrences recognized so far. These caprinid specimens are characterized by relatively modest sizes, moreover other rudists commonly part of the assemblage are lacking. The dominance of caprinids in the study area suggests a distal platform setting, i.e., close proximity to the platform edge.- Handle-ID: http://hdl.handle.net/2042/56397

Katarzyna Zalecka, Tomasz Wrzo?ek & Bruno Granier.- Simple and practical techniques to manage small databases, illustrated by a case study: bibliographic data from the "Fossil Cnidaria & Porifera" newsletter.- Small databases, i.e., with less than 15,000 entries, are sometimes handled using inappropriate, complex, and often expensive data management systems. We present and briefly discuss a few types of proprietary and open-source, relational and non-relational, server-based versus portable databases and specific tools to handle the latter. With a collection of nearly 7,000 bibliographic notes during its 40-year history "Fossil Cnidaria & Porifera (FC&P)", the newsletter of the "International Association for Study of Fossil Cnidaria and Porifera", was chosen as a case study. The analysis of the temporal trends in the FC&P bibliographic database shows a decrease over the years in the number of publications effectively reported in FC&P. Almost all relevant papers for the decade 1981-1990 are reported, but this good coverage ratio falls down to less than 50% after 2000; accordingly, the concern about the data representativeness is addressed in our interpretation. Besides the classical database management systems and spreadsheet software, which were originally used with the FC&P case study, we present two discrete, open-source, flat and portable options where data can be displayed using any widely available Internet browser, and that are suitable to handle most small databases (XML or JS files) as documented herein.- Handle-ID: http://hdl.handle.net/2042/56249

José R. Ovando-Figueroa, Josep A. Moreno-Bedmar, Gabriel Chávez-Cabello & Keith P. Minor.- Lower Aptian ammonites of the Sierra de Parras, Coahuila State, northern Mexico.- We report an interesting Aptian ammonite record from the La Peña Formation in the Sierra de Parras, Coahuila State. This assemblage is analyzed from a paleoecological perspective. It contains the first reported occurrence of a macroconch of Dufrenoyia from Mexico, and the largest known specimen of 'Gargasiceras' adkinsi. Such an assemblage yielding large ammonites is unusual in deposits of this age in Mexico. To properly document this ammonite record, we review 'Gargasiceras' adkinsi, formerly misidentified as Rhytidoplites robertsi, and allied taxa. From our analysis, we conclude that 'Gargasiceras' adkinsi exhibits strong intraspecific variability. We also analyze in detail the differences that exist between 'Gargasiceras' adkinsi and Rhytidoplites robertsi, and emend the concept of the genus Rhytidoplites. These revisions are important from a biostratigraphic point of view since 'Gargasiceras' adkinsi is an index species for the lower Aptian ammonite zonation of Mexico.- Handle-ID: http://hdl.handle.net/2042/56250
