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 Publication carnetsgeol@rediris.es Thu, 06 Aug 2015 16:58:05 GMT http://iopan.gda.pl/oceanologia/57_3.html * Spatial and temporal variability of sea surface temperature in the Baltic Sea based on 32-years (1982–2013) of satellite data.- Stramska Malgorzata, Białogrodzka Jagoda <br />* Heavy metals contamination and distribution of benthic foraminifera from the Red Sea coastal area, Jeddah, Saudi Arabia.- Youssef Mohamed <br />* Seasonal changes in phytoplankton on the north-eastern shelf of Kangaroo Island (South Australia) in 2012 and 2013.- Balzano Sergio, Ellis Amanda V., Le Lan Charlotte, Leterme Sophie C. <br />* Impact of Chinese mitten crab <i>Eriocheir sinensis</i/> on blue mussel <i>Mytilus edulis trossulus</i> – laboratory studies of claw strength, handling behavior, consumption rate, and size selective predation.- Wójcik Dagmara, Normant Monika, Dmochowska Barbara, Fowler Amy <br />* Engineering effect of <i/>Pinna nobilis</i/> shells on benthic communities.- Rabaoui Lotfi, Belgacem Walid, Ben Ismail Dorsaf, Mansour Lamjed, Tlig-Zouari Sabiha <br />* Changes in the parasite communities as one of the potential causes of decline in abundance of the three-spined sticklebacks in the Puck Bay.- Morozińska-Gogol Jolanta <br />* Sea spray aerosol flux estimation based on long-term variation of wave statistics.- Myrhaug Dag, Wang Hong, Holmedal Lars Erik Journal editor@iopan.gda.pl Tue, 04 Aug 2015 12:36:11 GMT http://paleopolis.rediris.es/cg/1511/ 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 Publication carnetsgeol@rediris.es Tue, 14 Jul 2015 16:49:00 GMT http://paleopolis.rediris.es/cg/1510/ 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 δ18O values (-18.6 to -10.9 VPDB) and δ13C values ranging from negative to positive (-2.6 to +2.5‰ VPDB). The absence of correlation between δ13C and δ18O values suggests a primary marine origin for the δ13C 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 Publication carnetsgeol@rediris.es Tue, 14 Jul 2015 16:46:15 GMT http://paleopolis.rediris.es/cg/1509/ Oldřich Fatka, Petr Budil, Catherine Crônier, Jessie Cuvelier, Lukáš 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.

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 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.

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 Publication carnetsgeol@rediris.es Mon, 09 Mar 2015 11:58:25 GMT http://paleopolis.rediris.es/cg/1505/ 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 Publication carnetsgeol@rediris.es Sat, 28 Feb 2015 11:20:57 GMT http://paleopolis.rediris.es/cg/1504/ 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 Publication carnetsgeol@rediris.es Sun, 15 Feb 2015 10:06:17 GMT http://paleopolis.rediris.es/cg/1503/ 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.

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 Publication carnetsgeol@rediris.es Wed, 14 Jan 2015 16:33:14 GMT http://paleopolis.rediris.es/cg/1501/ José R.

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 Publication carnetsgeol@rediris.es Wed, 14 Jan 2015 12:02:12 GMT http://paleopolis.rediris.es/cg/Guy_Tronchetti/ Michel Moullade.- In memoriam of my colleague and friend Guy Tronchetti (1938-2014).- The chief editor of a prestigious scientific journal, who is about to publish a major article of which Guy is one of the lead authors, replied to the news of his passing: "I am very sorry to hear about that.

In both units, the ooids are partly leached. More specifically, the ooid cortices were partly leached and some ooid nuclei appear suspended in the middle of cortical moldic cavities created by leaching, rather than having fallen to the bottom of these cavities before the final cementation take place. We demonstrate that these ooids were originally calcitic, not aragonitic, not "two-phase" nor "bimineral". This leaching is not an early diagenetic feature related to subaerial exposure, but a late diagenetic feature, possibly related to the migration of acidic pore waters, brought about by Alpine tectonics and/or karstification.- Handle-ID: http://hdl.handle.net/2042/56045 Publication carnetsgeol@rediris.es Wed, 24 Dec 2014 15:01:57 GMT http://paleopolis.rediris.es/cg/1421/ Bruno Granier.- Borings and etchings in the Upper Bathonian-Lower Callovian oolite of the Paris Basin (France).- The oolite of the "Dalle Nacrée" Formation in the Paris Basin is made of marine calcareous ooids with, from base to top, radial (and therefore likely to have been calcite), concentric and micritic fabrics, each corresponding to a discrete stratigraphic unit. Several hardgrounds and oolitic pebble-cobble layers in the succession are encrusted and bored. Three main types of boring have been identified ranging in sizes from some tens of µm (sponge borings) to centimeters (bivalve borings), with an intermediate category (worm borings). Some worm borings have rough walls, where early marine fibrous cement is less corroded than the cortices of cemented ooids. The key to understanding this differential dissolution could be related to organic matter, present within the ooid cortices but lacking in the fibrous cement. Polychaete worms that use chemical means (enzymes or acids) to bore are probably responsible for these peculiar borings. A secondary conclusion is that partly or fully leached ooid cortices do not necessarily indicate an original aragonitic mineralogy of the dissolved parts.- Handle-ID: http://hdl.handle.net/2042/56043 Publication carnetsgeol@rediris.es Wed, 24 Dec 2014 14:58:26 GMT http://paleopolis.rediris.es/cg/1420/ Tomasz Wrzołek.- Devonian Phillipsastreid tetracorals of the genus Rozkowskaella from the Holy Cross Mountains, Poland.- Solitary or weakly colonial Phillipsastreid tetracorals of the Upper Frasnian of Holy Cross Mountains, Poland, with triangular to oval shape of transverse-section and tendency towards reduction of the horseshoe dissepiments, are included here in the genus Rozkowskaella, with Rozkowskaella sandaliformis, R. cf. sandaliformis and Rozkowskaella sp.- Handle-ID: http://hdl.handle.net/2042/56041 Publication carnetsgeol@rediris.es Wed, 24 Dec 2014 14:55:40 GMT http://paleopolis.rediris.es/cg/1419/ Francesco Sciuto.- Two new species of Early Pleistocene marine ostracods from Southeast Sicily.- Two fossil species of Ostracoda belonging to the genera Urocythereis Ruggieri, 1950, and Semicytherura Wagner, 1957, discovered in the Lower Pleistocene shallow marine sandy-silty sediments outcropping at "Cartiera Molino" (F. 276, IV NO, Vittoria, Southeast Sicily) are described and figured.- Handle-ID: http://hdl.handle.net/2042/56039 Publication carnetsgeol@rediris.es Wed, 24 Dec 2014 14:35:09 GMT http://paleopolis.rediris.es/cg/1418/ Sibelle Maksoud, Bruno Granier, Dany Azar, Raymond Gèze, Jean-Claude Paicheler & Josep A. Moreno-Bedmar.- Revision of "Falaise de Blanche" (Lower Cretaceous) in Lebanon, with the definition of a Jezzinian Regional Stage.- The "Falaise de Blanche" is a prominent cliff, consisting mostly of Lower Cretaceous limestones that extends as linear outcrops over most of the Lebanese territory and provides geologists a remarkable reference for stratigraphic studies. However, until now, this unit was lacking a clear definition. We introduce herein the Jezzinian Regional Stage, the type-locality of which is at Jezzine. It equates as an unconformity-bounded unit and, per definition, it is framed by two discontinuities. Because we identified an additional, median sequence-boundary, poorly-expressed in the type-section but better at Aazour, only 4.5 km westward of Jezzine, the new regional stage implicitly spans two sequences. The lithostratigraphic framework being properly redefined, we were able to investigate time-constrained micropaleontological assemblages, consisting mostly of benthic foraminifers and calcareous algae. Typically Southern Tethysian, these assemblages contribute to high-resolution, holostratigraphic correlations with the Persian Gulf area, on the eastern part of the Arabian Plate. The Jezzinian interval correlates with the upper part of the Kharaibian Regional Stage (also known as "Thamama II" reservoir unit in the oil industry). In turn, the Jezzinian is indirectly correlated with the Northern Tethysian Urgonian stratigraphic units where it corresponds to a rather short interval encompassing the standard Barremian - Bedoulian stage boundary. Locally the upper discontinuity is associated to a significant intra-Bedoulian hiatus. The macrofossil assemblages found in the Jezzinian (echinids) and above it (ammonites) support, or at least do not contradict, our micropaleontological dating.- Handle-ID: http://hdl.handle.net/2042/54359 Publication carnetsdegeologie@hotmail.com Fri, 14 Nov 2014 17:55:40 GMT http://paleopolis.rediris.es/cg/1417/ Alain Bonnot, Pierre-Yves Boursicot & Patrice Ferchaud.- Les genres Subgrossouvria Spath et Orionoides Spath (Ammonitina, Perisphinctidae) de l'Horizon à Leckenbyi (Callovien supérieur, Zone à Athleta) de Montreuil-Bellay (Maine-et-Loire, France) [The genera Subgrossouvria Spath and Orionoides Spath (Ammonitina, Perisphinctidae) from the Leckenbyi Horizon (Upper Callovian, Athleta Zone) of Montreuil-Bellay (Maine-et-Loire, France)].- À Montreuil-Bellay (Maine-et-Loire, France), le premier banc d'âge Callovien supérieur (Horizon à Leckenbyi) a fourni une très abondante faune ammonitique (N=3275).

A base for the history of biogeographic provinces.- A general overview of the biodiversity of the marine fauna during the Tertiary period is developed in the context of the biogeographical evolution of the European realm. This study combines a reappraisal of the literature with a unique first-hand source of data on the richest marine group (the gastropods) from over a 25 million year period (Early Oligocene to Late Miocene). In total the French deposits have yielded more than 10,000 species from the Eocene to the Upper Miocene. Evidence of significant bias in the fossil record is pointed out for the Palaeocene (Danian) and Upper Eocene (Priabonian). For the period considered (Palaeocene to Late Miocene, ca 50 million years) the second highest diversity is reported in the Late Oligocene. This study reveals also the importance of pre-Miocene extinctions of genera. The Oligocene was when the latitudinal differentiation of the faunas was greatest. The local generic gastropod richness ranges from 59 (Rupelian of Belgium) to 494 (Chattian of Aquitaine). A clear trend towards homogenization appears in the Late Oligocene which leads to the development of a vast biogeographical region named Euro-West Africa. This faunal evolutionary pattern has never been demonstrated before and is a novel feature of the biogeography of the Eastern-Atlantic region.- Handle-ID: http://hdl.handle.net/2042/54150 Publication carnetsdegeologie@hotmail.com Tue, 14 Oct 2014 13:18:13 GMT http://paleopolis.rediris.es/cg/1413/ Didier Bert & Stéphane Bersac.- Origin of the Tethyan Hemihoplitidae tested with cladistics (Ancyloceratina, Ammonoidea, Early Cretaceous): an immigration event?.- The Late Barremian Hemihoplitidae (Ancyloceratina, Ammonoidea) are widely known in the northern Tethyan Margin and the Essaouira-Agadir Basin (Morocco). Their rapid evolution and diversification make them one of the key groups for that period, but their origin remains poorly known and several competing hypotheses have been published. These hypotheses are tested here with cladistic analysis in order to reject those receiving the least support and discuss those well supported. The analysis discards the Crioceratitidae, Emericiceratidae (Emericiceras and Honnoratia) and Toxancyloceras as stem-groups of the Hemihoplitidae (Gassendiceras). The Toxancyloceras appear instead to be a sister-taxon of the Moutoniceras, so we propose the latter to be classified with the Ancyloceratidae rather than with the Heteroceratidae. The best supported hypothesis assumes that the Hemihoplitidae first appeared suddenly in the Essaouira-Agadir Basin at the end of the Early Barremian from small populations of Boreal Paracrioceras. These latter could have migrated southward episodically before invading the northern Tethyan margin at the beginning of the Late Barremian.

These new data unequivocally document the presence of characteristic Berriasian-Valanginian taxa in these deposits.- Handle-ID: http://hdl.handle.net/2042/54001 Publication carnetsdegeologie@hotmail.com Thu, 03 Jul 2014 18:50:35 GMT http://paleopolis.rediris.es/cg/1410/ Oldřich Fatka & Vladislav Kozák.- A new type of entombment of Peronopsis (Agnostida) in a hyolithid conch.- An enrolled exoskeleton of the holaspid specimen of a tiny agnostid Peronopsis integra (Beyrich, 1845) entombed inside a conch of the hyolithid ?Buchavalites sp. is described from the middle Cambrian (Drumian) Jince Formation of the Příbram-Jince Basin (Czech Republic). The agnostid is associated with an ichnofossil of the feeding trace classified as Arachnostega-type behaviour. The enrolled attitude of the agnostid exoskeleton suggests that the specimen is a carcass rather than moult. Either the storm disturbance and/or well-protected source of food hypotheses could explain the entombed agnostid. This additional example supports a benthic mode of life in the agnostid P. integra. The studied association of feeding tunnels of an unknown Arachnostega-strategist and Peronopsis preserved inside a hyolithid conch is a case of "frozen" behaviour.- Handle-ID: http://hdl.handle.net/2042/54000 Publication carnetsdegeologie@hotmail.com Thu, 03 Jul 2014 18:44:20 GMT http://paleopolis.rediris.es/cg/1409/ Michel Hennebert.- The Cretaceous-Paleogene boundary and its 405-kyr eccentricity cycle phase: a new constraint on radiometric dating and astrochronology.- Radiometric dating and astrochronologic dating still suffer discrepancies without knowing which one gives the most reliable results. A new tool is proposed to constrain both the approaches. The phase of the 405-kyr signal with respect to the Cretaceous - Paleogene boundary event has been determined in the Aïn Settara section (Kalaat Senan, central Tunisia). We use this phase value (Option 2), as well as an average of phase values obtained from the literature (Option 1), to examine the relationship linking both the radiometric (absolute) age assigned to the K-Pg boundary and the Cenozoic average-value of the ~405-kyr eccentricity period. A new useful constraint emerges: to any absolute age assumed for the K-Pg boundary corresponds a value of the mean Cenozoic 405-kyr period, and vice versa. Supposing a K-Pg boundary radiometric age in the vicinity of 66.0 Ma, then the number of entire cycles (comprised between two minima of the 405-kyr eccentricity signal) within the Cenozoic Period could only be equal to 163. When adding to this figure the parts of the cycles preceding and following these 163 entire cycles the total duration of the Cenozoic Era becomes equal to 163.168 cycles (Option 1) or 163.081 cycles (Option 2). We propose to grant a special interest to the determination of the 405-kyr cycle phase at stratigraphically well documented levels, particularly those that correspond to world-wide, sudden and catastrophic events, that are well located in time by reliable radiometric dates.- Handle-ID: http://hdl.handle.net/2042/53981 Publication carnetsdegeologie@hotmail.com Thu, 19 Jun 2014 01:05:04 GMT http://paleopolis.rediris.es/cg/1408/ Christian C.

Longtemps considérée comme la forme méditerranéenne de N. anomala, son histoire est brièvement décrite. Récemment, N. turbinata a été considérée par plusieurs auteurs, comme une espèce valide, mais sur quelques caractères ne correspondant pas à ceux de la description originelle ; ils apparaissent comme des variations des caractères de N. anomala. La présence conjointe des deux "espèces" dans plusieurs localités surtout sur le plateau continental tend à accréditer leur synonymie. Celle-ci a été récemment corroborée par des analyses moléculaires et est discutée en prenant aussi en compte les caractéristiques des bassins méditerranéens et leur histoire depuis le Miocène. Novocrania turbinata synonym of N. anomala.- Anomia turbinata, or conical Anomia (= Novocrania turbinata), was described by Poli (1795) in the bathyal environment off the coast of the Kingdom of the Two Sicilies, Patella anomala Müller, 1776 (= N. anomala) being considered a synonym. The history of this species, commonly considered as the Mediterranean form of N. anomala, will be described. Recently, several authors have described N. turbinata as a valid species on the basis of shell variations, as compared to N. anomala. After analysis of the taxonomic validity of these characters, both species are considered as synonymous. That is supported by their occurrence in various localities, mainly in the continental shelf. Their synonymy has been corroborated by molecular analyses and is discussed with reference to the characteristics of the Mediterranean basins and their history since the Miocene.- Handle-ID: http://hdl.handle.net/2042/53979 Publication carnetsdegeologie@hotmail.com Thu, 19 Jun 2014 01:01:18 GMT http://iopan.gda.pl/oceanologia/56_3.html * Recent sea surface temperature trends and future scenarios for the Mediterranean Sea.- Shaltout Mohamed, Anders Omstedt

(Sporolithaceae, Sporolithales, Rhodophyta), a 100 million year old fossil coralline red alga from north-eastern Brazil, and a new Hauterivian record of Sporolithon from Switzerland.- Fossil specimens of Heydrichia (?) poignantii, sp. nov. (Sporolithaceae, Sporolithales, Rhodophyta), representing the first confirmation of the genus in the fossil record, were discovered in thin sections of Albian limestones from the Riachuelo Formation, Sergipe Basin, and in thin sections of Albian - Cenomanian limestones from the Ponta do Mel Formation, Potiguar Basin in north-eastern Brazil. A detailed morphological-anatomical account of the species is provided, and its placement in Heydrichia is discussed in relation to current classification proposals. Comparisons with the four other known species of the genus, all non-fossil, show that H. poignantii is the only known species of Heydrichia in which thalli are encrusting to sparsely warty to horizontally layered with overlapping lamellate branches that commonly appear variously curved or arched, and in which thalli have sporangial complexes that become buried in the thallus. The evolutionary history of Heydrichia remains uncertain, but available data suggest that the genus may have diverged from the sporolithacean genus Sporolithon, known as early as Hauterivian times (c. 129.4-132.9 ± 1 Ma) from Spain (and newly reported here from Switzerland), or it may have arisen from a graticulacean alga such as Graticula, dating from mid-Silurian times (c. 427-435 Ma). Current data also suggest that Heydrichia is more likely to have arrived in Brazil from Central Atlantic waters than from higher latitude South Atlantic waters. This implies that currently living species in southern Africa probably arose later from ancestors further equatorward in the South Atlantic, although confirming studies are needed. All non-fossil species of Heydrichia are known only from the southern hemisphere.- Handle-ID: http://hdl.handle.net/2042/53736 Publication carnetsdegeologie@hotmail.com Thu, 08 May 2014 00:56:32 GMT http://paleopolis.rediris.es/cg/1406/ Fernando Nuñez-Useche, Josep Anton Moreno-Bedmar, Miguel Company & Ricardo Barragán.- A negative carbon isotope excursion within the Dufrenoyia furcata Zone: proposal for a new episode for chemo-stratigraphic correlation in the Aptian.- In this work we discuss a proposed updated division of the C7 isotope segment of Menegatti et al. (1998). The new standard division of the segment C7 is based on a revision of published Barremian-Aptian carbon isotope curves from stratigraphic sections of the Prebetic Domain in Spain. It includes four distinct isotopic subunits labeled C7a to C7d, with a characteristic negative carbon isotope excursion at the base of the segment and which correlates with the Dufrenoyia furcata ammonite Zone. The negative excursion is recognized on a regional extent, and the term Intra-Furcata Negative Excursion (IFNE) is proposed to identify it. We provide possible sites correlatable with the IFNE in both the Old and New worlds, which suggest its potential use as an even global chemostratigraphic marker for the Aptian record.- Handle-ID: http://hdl.handle.net/2042/53734 Publication carnetsdegeologie@hotmail.com Thu, 08 May 2014 00:51:52 GMT http://paleopolis.rediris.es/cg/1405/ Francis Amédro & Bertrand Matrion.- L'étage Albien dans sa région-type, l'Aube (France) : une synthèse dans un contexte sédimentaire global.- Le département de l'Aube est la région-type de l'étage Albien créé par d'Orbigny (1842). Deux formations sont reconnues dans les faciès argileux ou "Gault" auct. du stratotype : les Argiles tégulines de Courcelles (82 m) surmontées des Marnes de Brienne (43 m). La limite entre les deux formations est définie au sommet d'un niveau induré (hardground L'Étape) aisément identifiable à la fois sur le terrain et en sondages. La région-type de l'étage Albien est particulièrement intéressante en raison de l'épaisseur exceptionnelle des faciès argileux (plus de 120 m), une situation unique dans le bassin anglo-parisien. Aujourd'hui, 82 % de la succession lithologique sont connus précisément grâce à 16 affleurements. Dans deux intervalles épais respectivement de 33 m et 28,50 m, une suite lithologique composite continue est construite à l'aide de coupes qui se suivent et se relaient, corrélées l'une à l'autre sur le terrain à l'aide de niveaux repères. Six faciès successifs sont décrits : dans les Argiles tégulines de Courcelles et du bas vers le haut : 1 - lit de nodules gréso-phosphatés ; 2 - argiles silteuses ; 3 - argiles et bancs calcaires ; dans les Marnes de Brienne : 4 - marnes argileuses ; 5 - gaize ; 6 - marnes argileuses. À une échelle plus fine, une rythmicité est démontrée dans la sédimentation. Elle se traduit dans les Argiles tégulines de Courcelles par des cycles pluri-décimétriques débutant par des niveaux silteux et limités au sommet par des surfaces perforées. Dans les Marnes de Brienne, les cycles, métriques (sauf dans la gaize où ils sont décimétriques), montrent des alternances de marne argileuse gris foncé et de marne gris pâle annonçant les craies rythmées du Cénomanien. Ces couplets correspondent probablement à des cycles de précession des équinoxes (20 ka). Treize événements à caractère lithologique (lits de nodules phosphatés, fonds durcis, niveaux riches en sable quartzeux et glauconie) et écologiques (horizons caractérisés par l'abondance momentanée d'un certain nombre de fossiles) sont identifiés dans la suite stratigraphique. Ces niveaux repères sont très utiles pour des corrélations précises à travers le bassin. Une comparaison est proposée entre les faciès sableux de l'Yonne et les faciès argileux de l'Aube. La continuité de plusieurs lits de nodules phosphatés est démontrée depuis l'Yonne au sud-ouest jusqu'à l'Aube et le Perthois au nord-est, sur une distance supérieure à 130 km. Ces niveaux repères sont interprétés comme des surfaces d'inondation de cycles eustatiques de 3e ordre. Enfin, une étude détaillée de la lithologie, complétée par une analyse des faunes d'ammonites et d'inocérames, est utilisée pour une interprétation séquentielle. Le résultat est l'identification de huit séquences eustatiques de 3e ordre dans la moitié supérieure des Argiles de Courcelles et les Marnes de Brienne, dont deux nouvelles séquences indexées AL 5a et AL 6a. The Albian Stage in its type area, the Aube (France): a synthesis in a global sedimentary context.- The Aube department is the type locality of the Albian stage created by d'Orbigny (1842). Two formations are recognised in the clay facies (the "Gault" auct.) of the stratotype, the Argiles tégulines de Courcelles (82 m), which is overlain by the Marnes de Brienne (43 m). The boundary between the two formations is defined at the top of an indurated bed (hardground L'Étape) that is readily identifiable, both in the field, and from boreholes. The type area of the Albian stage is of great interest because of the size of the clay facies (more than 120 m) unique in the Anglo-Paris basin. Today, 82 % of the lithological succession is documented accurately from 16 outcrops. In two intervals of respectively 33 m and 28.50 m thick, composite sections are made of overlapping sections which are correlated in the field with the help of lithological marker beds. Six successive facies are described: in the Argiles tégulines de Courcelles and from bottom to top: 1 - phosphatic nodules bed; 2 - silty clays; 3 - clays and limestone beds; in the Marnes de Brienne: 4 - clay marls; 5 - gaize; 6 - clay marls. On a smaller scale, a decimetre to metre-scale rhythmicity can be identified in the sedimentation. This is reflected in the Argiles tégulines de Courcelles by pluri-decimetric cycles that start with a silty level and are bounded at the top by a bored surface. In the Marnes de Brienne, the metric cycles (except for the gaize where they are decimetric) exhibit alternating dark grey clay marl and a pale grey marl that herald the rhythmic chalks of the Cenomanian. Individual couplets probably represent the precession cycles (20 kyr). On the other hand, 13 lithoevents as phosphatic nodules beds, hardgrounds, glauconitic and sandy beds and ecoevents characterised by the brief abundance of some fossils. These marker beds are very useful for fine correlations across the basin. A comparison is proposed between sandy units of Yonne and clay facies of Aube. The continuity of several phosphatic nodules beds is shown from Yonne in the South West to Aube and Perthois in the North East, that is a distance exceeding 130 km. These marker beds are interpreted as Flooding Surfaces of 3rd-order cycles. Finally, a detailed study of the lithology, complemented with the analysis of the ammonite and inoceramid faunas, is used for a depositional sequence interpretation. As a result, eight sequences are identified in the upper half of the Argiles tégulines de Courcelles and in the Marnes de Brienne in the type area of the Albian stage, including two new sequences indexed AL 5a and AL 6a.- Handle-ID: http://hdl.handle.net/2042/53732 Publication carnetsdegeologie@hotmail.com Thu, 08 May 2014 00:42:26 GMT http://paleopolis.rediris.es/cg/1404/ Vicent Vicedo, José Antonio Berlanga & Josep Serra-Kiel.- Paleocene larger foraminifera from the Yucatán Peninsula (SE Mexico).- The larger foraminifera found in the material from the Chichen Itzá Formation of Campeche (SE Mexico) were studied in detail.

Scott.- A Cretaceous chronostratigraphic database: construction and applications.- Timing and rates of tectonic events, evolutionary processes, and oceanographic and paleoclimatic changes must be based on high-precision numerical age calibration of stages defined in Global Stratotype and Section Points (GSSPs). The Cretaceous Chronostratigraphic Database (CRETCSDB3) is an objective, testable database that calibrates select Cretaceous events and enables high-resolution chronostratigraphic correlations. CRETCSDB3 is a compilation of more than 3500 taxa and marker beds in nearly 300 published sections calibrated to a mega-annum (Ma) scale. The database spans the Jurassic/Cretaceous and the Cretaceous/Paleogene boundaries. Construction of CRETCSDB3 began by plotting bioevents in the Kalaat Senan, Tunisia, Cenomanian-Turonian section to the 1989 time scale. The sedimentology, sequence stratigraphy, and biostratigraphy of this section were precisely documented and stage boundaries defined biostratigraphically. Additional sections with radiometrically dated beds were graphed to constrain the accuracy of the numerical scale. Ranges of first and last occurrences are calibrated to mega-annums of Cretaceous stages defined by GSSPs or reference sections. This database serves as a look-up table for interpolation and age calibration of other stratigraphic sections. The age ranges of some taxa and marker beds are preliminary and may be extended as new sections are added to the database. CRETCSDB3 tested the numeric age calibration of the Albian/Cenomanian boundary. This boundary in North Texas accurately correlates with the GSSP in France by ammonites, planktic foraminifers and dinoflagellates. This stage boundary in North Texas correlates with the 97.88±0.69 Ma Clay Spur Bentonite in Wyoming by sequence stratigraphy and cosmopolitan dinoflagellates. The inconsistency between this age and the current 100.5 Ma date of the 2012 Geologic Time Scale remains to be evaluated independently.- Handle-ID: http://hdl.handle.net/2042/53522 Article carnetsdegeologie@hotmail.com Fri, 28 Feb 2014 18:31:20 GMT http://iopan.gda.pl/oceanologia/56_1.html *Simple statistical formulas for estimating biogeochemical properties of suspended particulate matter in the southern Baltic Sea potentially useful for optical remote sensing applications .- Woźniak Sławomir B. <br />*Biometry and reproductive biology of Pseudonereis anomala Gravier 1901 (Polychaeta: Nereididae) on the Alexandria coast, Egypt .- Hamdy Rasha, Dorgham Mohamed Moussa,El-Rashidy Hoda Hassan, Atta Manal Mohamed <br />*Principal Component and Cluster Analysis for determining diversification of bottom morphology based on bathymetric profiles from Brepollen (Hornsund, Spitsbergen).- Moskalik Mateusz, Tęgowski Jarosław, Grabowiecki Piotr, Żulichowska Monika <br />*Sediment deposition and accumulation rates determined by sediment trap and²¹⁰Pb isotope methods in the Outer Puck Bay (Baltic Sea).- Szmytkiewicz Angelika, Zalewska Tamara <br />*Effect of accessory pigment composition on the absorption characteristics of a dinoflagellate bloom in a coastal embayment.- Vijayan Anil Kumar, Somayajula Srikanth Ayyala <br />*Non-native crab Rhithropanopeus harrisii (Gould, 1984) - a new component of the benthic communities in the Gulf of Gdańsk (southern Baltic Sea).- Hegele-Drywa Joanna, Normant Monika <br />*Evadne anonyx G.

Wilson.- Silurian cornulitids of Estonia (Baltica).- Seven species of cornulitids are systematically described from the Silurian of Saaremaa and Hiiumaa islands, Estonia. There are three species of cornulitids in the Rhuddanian, three in the Sheinwoodian, single species in the Gorstian and Ludfordian, and three species in the Pridoli. Cornulitids have a facies range from pelletal limestones of shoal environments to deeper ramp marls. Endobiotic cornulitid symbionts occur in stromatoporoids found in shoal and open shelf zones. Gregarious aggregates are restricted to the limestones of the open shelf zone possibly because of higher nutrient levels in open shelf zone waters as compared to those of the deeper ramp. Unattached free forms are especially common in offshore deeper ramp marls presumably due to their adaption to life on a soft bottom. Solitary attached forms occur in all facies zones where cornulitids are present. Because the life modes of cornulitids are closely associated with particular facies zones, they are useful tools for paleoecological reconstructions.- CG2013_A09.- Handle-ID: http://hdl.handle.net/2042/53034 Article carnetsdegeologie@hotmail.com Wed, 25 Dec 2013 12:02:34 GMT http://paleopolis.rediris.es/cg/CG2013_B02/ Zbigniew Kotański.- Anisian Dasycladales from Upper Silesia and adjacent regions.- Anisian Dasycladales (calcareous algae) from the Diplopora Dolomite of the Upper Silesia and adjacent regions of S Poland are revised. All previously reported taxa are critically reviewed and illustrated. New paleontological samples were collected from 74 outcrops and from 45 boreholes. The abundant material includes both specimens visible on fractured rock surfaces and thin-sectioned ones; 24 species of Dasycladales are identified, including three new species: Oligoporella chrzanowensis n.sp., Physoporella polonoandalusica n.sp., and Salpingoporella krupkaensis n.sp. Best-preserved specimens are illustrated in 39 plates. The identified species were compared with Alpine and Carpathian forms of stratigraphic importance. Six Dasycladalean local horizons are defined. The Pelsonian-Illyrian boundary occurs in the middle part of the Diplopora Dolomite. Its uppermost part, despite the presence of Diplopora annulata, belongs to the Illyrian, not to the Fassanian, as also corroborated by conodont correlations. The peculiar state of preservation (internal moulds and double tubes) is discussed; it is due to early syngenetic dolomitisation. The palaeoenvironment of the algae is determined as sublittoral. Dasycladales flourished upon a peri-Tethyan carbonate platform, widely connected with the Alpine-Carpathian seas. Five palaeoecological assemblages are recognized, differing in their bathymetric and turbulence conditions, and living in marine shoals and shallow basins separating them. The Upper Silesian platform was separated from the hypersaline Germanic Basin of the Middle Muschelkalk by banks and oolite and bioclastic barriers, blocking dispersal of marine biota. A wide connection existed with the Alpine-Carpathian seas, allowing immigration of High-Tatric, Križna and even South Alpine flora to the Upper Silesian Carbonate Platform.- CG2013_B02.- Handle-ID: http://hdl.handle.net/2042/53036 Book carnetsdegeologie@hotmail.com Wed, 25 Dec 2013 11:50:58 GMT http://paleopolis.rediris.es/cg/CG2013_L07/ Bruno Granier.- Dissocladella hauteriviana Masse in Masse et al., 1999 (non Masse, 1976), another lower Urgonian Dasycladalean alga revisited.- First ascribed to the Triploporellacean genus Dissocladella (Pia in Rao & Pia, 1936), the species D. hauteriviana Masse in Masse et al., 1999, was supposedly characterized by a thallus bearing whorls of laterals each consisting of a stumpy primary with a tuft of four slim secondaries at its top. A restudy of the laterals proves that they split, not only once, but several times, and stepwisely decrease in diameter. The species is re-ascribed to the Family Thyrsoporellaceae in a new combination to the genus Deloffrella Granier & Michaud, 1987. Its known stratigraphic range is rather short (Late Valanginian-earliest Barremian). In addition, it disappears earlier than its companion Polyphysacean alga, i.e., Clypeina paucicalcarea (Conrad, 1970), and its geographical distribution is broader, which makes it a good index fossil for lower Urgonian carbonate platform series.- CG2013_L07.- Handle-ID: http://hdl.handle.net/2042/53035 Letter carnetsdegeologie@hotmail.com Wed, 25 Dec 2013 11:48:36 GMT http://paleopolis.rediris.es/cg/Jean-Paul_Colin/ Pierre Carbonel, Maria Cristina Cabral & Dan L. Danielopol.- Obituary notice: Jean-Paul Colin.- Jean-Paul Colin (1948 - 2013) passed away at the end of this summer and his departure is a cruel loss for our community, not only as a scientist of international repute, but also as an outstanding organizer and, for a number of us, as a good friend. Following his PhD degree in micropaleontology from the University of Paris VI in 1973, he spent his entire career in the exploration branch of the oil industry, first with EXXON in Houston and Bègles from 1974 to 1989, and then with ESSO REP in Bègles from 1989 to 2000. Initially, he worked on biostratigraphical micropaleontology, and later focused on ostracods, sequence stratigraphy and stratigraphic syntheses. From 2000 and until recently, he provided consultancy to several oil companies. Jean-Paul Colin also gave training courses to PETROBRAS and PETROCI, as well as workshops in Brazil (UNISINOS, São Leopoldo; University of Brasília; PETROBRAS, Rio de Janeiro) and Portugal (University of Lisbon). He taught applied micropaleontology in ENSEGID Bordeaux 3 and was a Research Associate at the University of Lisbon. His scientific work has never slowed down. Throughout his career and into retirement, he published or contributed to more than 300 publications and presentations at international conferences. Many times he was invited as a member for thesis juries in France and abroad. He was an internationally recognized authority on ostracods, especially those of the Cretaceous, but also had an excellent knowledge of the whole group throughout the post-Paleozoic time interval. Jean-Paul Colin was a great field and laboratory naturalist and as a scientific partner was always open to often lively discussion. His enthusiasm for the ostracods was huge and it was a pleasure to discuss with him. His special qualities were: that he was familiar with all the relevant literature; he had an encyclopedic memory; he always knew where to find the necessary literature and was able to comment on the specimens under investigation. He quickly identified the interesting and unusual subjects to be published. Being a very friendly person, he helped ostracodologists worldwide who went to him with questions, particularly the young. Besides these activities, Jean-Paul Colin was member of the editorial board of several international journals: A Stereo Atlas of Ostracod Shells, African Geosciences Journal, Annales de Paléontologie, Open Journal of Paleontology, and the Paleontology Journal. He was associate editor of Carnets de Géologie and Revue de Micropaléontologie. Jean-Paul Colin was a member of several scientific societies (Société Géologique de France, The Micropalaeontological Society, The International Paleontologists Association, Association des Paléontologues Français, Association des Géologues du Sud-Ouest). He was also actively involved for many years in the life of the Réserve Naturelle de Saucats-La Brède (Natural Reserve of Saucats-La Brède). After 2000, he was the soul and inspiration for the meetings of the Ostracodologistes de Langue française that he opened up beyond the French-speaking community. He will remain a focal point for the community and a facilitator hard to replace.- Jean-Paul_Colin.- Handle-ID: http://hdl.handle.net/2042/51849 Letter carnetsdegeologie@hotmail.com Fri, 22 Nov 2013 11:29:07 GMT http://paleopolis.rediris.es/cg/CG2013_L06/ Josep A.

Emig.- Daniel Œhlert (1849-1920) : biographie scientifique et bibliographie.- Daniel Œhlert a fait toute sa carrière à Laval (Mayenne, France). Ses fonctions de bibliothécaire de la ville de Laval, puis de conservateur des musées d'archéologie et d'histoire naturelle de Laval, lui laissaient une indépendance pour se consacrer à la paléontologie et à la géologie. Avec son épouse Pauline, ils partageaient leurs recherches entre des études sur le terrain dans la Mayenne et la Sarthe et de longs séjours à Paris, surtout à la Sorbonne. Les travaux d'Œhlert ont principalement porté sur les peuplements des mers paléozoïques du Maine, de l'Anjou et du Cotentin. Œhlert se consacra plus particulièrement à l'étude des Crinoïdes, des Trilobites et surtout des Brachiopodes. Dans leur collection, déposée au Musée des Sciences à Laval, on compte plus de 20 nouveaux genres avec plus de 150 nouvelles espèces d'invertébrés. L'œuvre géologique et stratigraphique d'Œhlert est largement originale ; elle ne concerne pratiquement que des terrains paléozoïques des départements de la Mayenne et de la Sarthe et, accessoirement, des départements de l'Orne et de l'Ille-et-Vilaine. En 1884, il devient collaborateur au Service de la Carte géologique de France.

The absence of encrustation on the upper bedding surface also is evidence that these traces are soft-sediment burrows rather than hardground borings.

Later on new combinations were introduced but did not meet a general agreement among paleophycologists. Considering the current acception of the Dasycladalean families, we ascribe it to the Family Polyphysaceae and subsequently to the genus Clypeina (Michelin, 1845). Its known stratigraphic range is rather brief (Late Hauterivian-Early Barremian), which makes it a good index fossil in Urgonian carbonate platform series. Its geographical distribution is apparently restricted to Western Europe (France, Spain and Switzerland).- CG2013_L01.- Handle-ID: http://hdl.handle.net/2042/48737 Letter carnetsdegeologie@hotmail.com Thu, 28 Feb 2013 16:38:08 GMT http://paleopolis.rediris.es/cg/CG2013_B01/ Bruno Granier & Nestor J.
