On the occurrence of the ammonite aptychi Lamellaptychus cf. rectecostatus (Peters, 1854) from the Ogrodzieniec quarry (southern Poland)

The largely Kimmeridgian-Tithonian (Late Jurassic) aptychus Lamellaptychus rectecostatus (Peters, 1854) is considered to represent the jaw apparatus of the ammonite superfamily Haploceratoidea (Family Oppeliidae). However, here, from the Ogrodzieniec quarry (southern Poland), we present its unusual allochthonous occurrence embedded in a perisphinctid, Perisphinctes (Kranosphinctes) sp., and co-occurring with a late early Oxfordian Cordatum Subzone (Cordatum Zone) ammonite assemblage. The assemblage includes Cardioceras (Cardioceras) cf. cordatum (Sowerby), Neocampylites delmontanus (Oppel), Lissoceratoides erato (d’Orbigny), Bukowskites distortus (Bukowski), Trimarginites cf. arolicus (Oppel), Glochiceras sp., Holcophylloceras zignodianum (d’Orbigny) and Euaspidoceras (Euaspidoceras) perarmatum (Sowerby).     

Anglesites gen. nov. (Ammonoidea, Ancyloceratina), un nouveau genre d’ammonites hétéromorphes du Barrémien supérieur du Sud-Est de la France

The revision of the Crioceras puzosianum d’Orbigny, 1842 made during the revision of the Paléontologie Française of d’Orbigny, shows that this taxon belongs to a new genus: Anglesites gen. nov. This new genus, from upper Barremian age, is monospecific for the moment and is homeomorphic to the Leptoceratoides from the Lower Barremian. It is temporarily included in the subfamily of the Leptoceratoidinae. A neotype for the “Crioceras” puzosianum d’Orbigny, 1842 is herein designated.     

Distribution and Abundance of Fauna on Living Tissues of Two Brazilian Hermatypic Corals (Mussismilia hispida (Verril 1902) and Siderastrea stellata Verril, 1868)

This study describes the distribution and abundance patterns of the associate fauna on the living surface of the corals Siderastrea stellata Verril, 1868 and Mussismilia hispida (Verril 1902) using a non-destructive method, on the northern coast of Rio de Janeiro State. For each coral species, infestation density and proportions of infested colonies, colonies attached and unattached to the substrate were estimated. A total of 474 colonies of S. stellata and 452 colonies of M. hispida were examined. The barnacle Ceratoconcha floridana (Pilsbry, 1931) was the dominant coral associate found, followed by gall-crabs of the family Cryptochiridae Paulson, 1875 and the bivalve Lithophaga bisulcata (d’Orbigny, 1842). Both coral species presented similar patterns of infestation dominance. S. stellata colonies were more commonly infested and showed a greater mean infestation density of 0.62 ind/cm² at Armação dos Búzios, whereas M. hispida colonies had infestation densities of only 0.20 ind/cm². Infestation density does not appear to impact negatively on corals of Armação dos Búzios. A clear negative relationship between the number of associates in the coral colony and coral size was found. Evidently abundance and frequency of occurrence of associated fauna is highly related to coral community structure and composition and the results highlight the importance of local scale studies.     

Turonian flora from the fossiliferous flints of Châtellerault (western France)

Three new localities yielding fossiliferous flints are reported from the Châtellerault area (Vienne, western France). They include one archaeological site (La Grande Vallée) and two zones with alterite deposits (L’Aunas and Les Bariollières). Broken surfaces of flint nodules show co-occurrence of marine invertebrates such as bryozoans, echinoids (Micraster Agassiz, Orthopsis Cotteau), gastropods (Acteonella d’Orbigny), rudists, and sponges. The association of Acteonella, Micraster and Orthopsis confirms the Turonian age (Upper Cretaceous) of the fossil assemblage. The marine invertebrates co-occur with plant macroremains including fragments of conifer leafy axes such as Brachyphyllum? Brongn., Frenelopsis (Schenk) emend. J. Watson and Geinitzia Endl., as well as fragments of angiosperm leaves. Plant remains are preserved as siliceous permineralizations, showing the gross morphology and all tissues in three dimensions. The fossil assemblage suggests that sediments were deposited proximally along the shoreline in shallow environment influenced by both continental and marine inputs. This coastal area was close to a conifer-dominated forest ecosystem, Geinitzia being probably one of the main components of the flora.     

Upper Cenomanian bivalves from the Guir Basin (southwestern Algeria): Order Veneroida

The Upper Cretaceous rocks are widely distributed and well exposed in south Algeria and consist in beds rich in macrofauna. For the first time, twenty veneroid species (Bivalvia) are systematically described from the upper Cenomanian deposits of the Guir Basin. While three species were reported since long before [Granocardium desvauxi (Coquand), G. productum (J. de C. Sowerby) and Glossus aquilinus (Coquand)]; Lucina fallax Forbes, Crassatella (Rochella) tenuicostata (Seguenza), Protocardia hillana (J. Sowerby), G. productum (J. de C. Sowerby) var. byzacenica (Pervinquière), Arctica cordata (Sharpe), A. humei (Cox), A. inornata (d’Orbigny), A. picteti (Coquand), Tenea delettrei (Coquand), Paraesa faba (J. de C. Sowerby), Meretrix desvauxi (Coquand) were previously unknown from the Cretaceous of Algerian Sahara. Because of reduced degree of preservation, Sphaera cf. corrugata J. Sowerby, Maghrebella cf. forgemoli (Coquand), Maghrebella sp., Granocardium cf. carolinum (d’Orbigny), Protocardia sp. and Meretrix sp. are tentatively determined. The studied material, found in the lower part of the “Calcaires de Sidi Mohamed Ben Bouziane” Formation, evidences palaeobiogeographic affinities occurring over a wide geographical area: from North Africa, southern Europe to Middle East and India. The present study provides new information to the knowledge of the upper Cenomanian palaeobiology of the studied region.     

Les Crustacés récoltés par dˈOrbigny en Amérique du Sud et déposés au Muséum national dˈhistoire naturelle,Paris

The important collection of Crustacea assembled by dˈOrbigny during his voyage of exploration in South America (1826–1834) was studied by Henri Milne Edwards and Hippolyte Lucas (1842–1844) in their contribution to the natural history of the Voyage en Amérique méridionale. In the present paper, this material, mainly crabs, deposited in the dry collection of the ‘Muséum national dˈhistoire naturelle’, Paris, is reviewed. The authors of the described taxa and their dates of publication are specified, lectotypes are designated, and a list of the currently valid taxa is provided.     

Revised classification and phylogeny of an Afrotropical species group based on molecular and morphological data,with the description of a new genus (Coleoptera: Scarabaeidae: Onthophagini)

The worldwide distributed Onthophagus genus comprises at present more than 2000 species, that often show a complicated and uncertain systematic history. In particular, the many Afrotropical species included in this genus have never been entirely reviewed after the division into 32 species groups proposed by d’Orbigny in 1913, although subsequent researches focusing on some of these species suggested that Onthophagus constituted a nonmonophyletic taxon. In order to highlight their phylogenetic relationships, the various Afrotropical species groups of d’Orbigny must thus be examined, and it would be advisable to study them separately to avoid misunderstanding. In this framework, the taxonomic position of the three species currently included in the 21st d’Orbigny group was examined. Both morphological and biomolecular analyses contributed in confirming that these species (i.e., Onthophagus caffrarius d’Orbigny, 1902; Onthophagus quadraticeps Harold, 1867; and Onthophagus signatus Fåhraeus, 1857) constituted a well-defined monophyletic group that cannot be maintained within the genus Onthophagus. Therefore, the Kurtops gen.n. is here described to accommodate these Afrotropical species, that are nevertheless always included within the Onthophagini tribe. On the basis of the phylogenetic relationships here elucidated, it was also emphasized that the new genus is strictly related to Digitonthophagus and Phalops; thus, it was proposed to include the three genera into a single clade of suprageneric rank naming it as Phalops complex.     

New record of Discradisca (Brachiopoda: Discinidae) from the Early Miocene of the Aquitaine Basin,south-western France

The linguliform inarticulate brachiopod genus Discradisca Stenzel, 1964 has been identified for the first time from the Early Burdigalian (Early Miocene) sandy deposits of the Aquitaine Basin, south-western France. The species studied here, D. multiradiata (de Morgan, 1915), originally described from the Middle Miocene of the Loire Basin, north-western France, is characterized by a small size, ornamentation of numerous (up to 100), fine but distinct and beaded tuberculate ribs, and an apex situated subposteriorly to subcentrally. The ecological and taphonomic aspects of this species are also presented. The attribution of some previously described Discinisca Dall, 1871 species from the Tertiary to the genus Discradisca is discussed.     

Fimbria lohani (Mollusca : Bivalvia) nomen novum pro Fimbria subpectunculus (d’Orbigny, 1850) du Lutétien (Éocène moyen) du bassin de Paris,nom préoccupé

Fimbria lohani (Mollusca: Bivalvia) nom. nov. pro Fimbria subpectunculus (d’ Orbigny, 1850) from the Lutetian (Middle Eocene) of Paris basin, name preoccupied. The names Fimbria magna ( Anton, 1838) and Fimbria subpectunculus (d’ Orbigny, 1850) are nomenclaturally invalid to designate the species from the Lutetian (Middle Eocene) of the Paris Basin. Fimbria lohani nom. nov. is proposed here as a replacement to correct the homonymy Corbis subpectunculus d’ Orbigny, 1850 non d’ Archiac, 1850.     

Nouvelles données paléontologiques sur le genre Dissimilites Sarkar, 1954

A nearly complete specimen of a heteromorphic ammonite belonging to the genus Dissimilites Sarkar, 1954 (Ammonoidea, Ancyloceratina) has been collected in the Lower Barremian from south-east France. It is the first time that a such sample has been collected since the discovery by d'Orbigny in 1842 of the first specimens belonging of this taxon. Hypothetic until today, the existence of a spire in the first development of the shell is confirmed and a new diagnosis of the genus is given. Finally, the specific content of the genus is briefly analyzed as also its stratigraphical occurrence.

Cenomanian cheilostome bryozoans from Devon,England

The Cenomanian witnessed a spectacular evolutionary radiation of cheilostome bryozoans, both in terms of species diversity and morphological disparity. However, Cenomanian cheilostome faunas are inadequately known. Twelve species of cheilostome bryozoans are here described from the Cenomanian Beer Head Limestone Formation of SE Devon, England, a nearshore facies of limestones and sands. Two of the cheilostome species are new – Wilbertopora manubriformis sp. nov. and Foratella cervisia sp. nov. – and five cannot be identified beyond genus level. Syntypes of Foratella forata (d’Orbigny, 1853), the Senonian type species of Foratella Canu, 1900, are illustrated using SEM and a lectotype is chosen. All of the species present are neocheilostomes, which were larval brooders. Compared with the non-brooding malacostegans that dominate pre-Cenomanian faunas, most species have avicularia and extensive frontal walls, features probably adaptive against small predators.     

Neocrassinid bivalves (Heterodonta) from the Middle Bathonian (Jurassic) of Kachchh,Western India

Six bivalve taxa belonging to the genusNeocrassina Fischer have been described from Middle Bathonian (Middle Jurassic) rocks of Kachchh, Western India. Of these,Neocrassina (N.) ovata (Smith), TV.(N.) robusta (Etallon) andN. (N.) paphia (d?Orbigny) have been recorded previously from various parts of Europe, whileNeocrassina (N.) pandeyi Maithani is an endemic faunal element as areNeocrassina (N.) sp. A andNeocrassina (N.) sp. B. The generic and sub-generic characters ofNeocrassina are reviewed as are affinities of the taxa with closely related forms from India and other parts of the world.     

ANATOMY AND SYSTEMATIC PLACEMENT OF SAYELLA LAEVIGATA (GASTROPODA: PYRAMIDELLIDAE: SAYELLINAE)

The ectoparasitic snail Sayella laevigata was first describedby Orbigny (1842) and first placed in the genus Sayella by Odé (1994) without discussion. This study provides justificationfor this assignment to the genus Sayella Dall, 1885 and to the subfamilySayellinae Wise, 1996. Sayella laevigata possesses an elongatepenis, with subapical swelling tapering to a short terminalnipple, that is characteristic of the genus.     

Proposed validation of the specific namescrenatus Bruguière, 1789, andrenggeri Oppel, 1863 (Class Cephalopoda,Order Ammonoidea) from the Oxfordian stage of the upper jurassic

Ammonites crenata Bruguière (1789) is one of the oldest species names used in modern ammonite taxonomy. This is a nomen dubium that is probably a synonym of what modern authors callCreniceras renggeri (Oppel 1863), a common species of the early Oxfordian.Ammonites crenatus Bruguière in Oppel (1863) is a stratigraphically junior taxon of the middle Oxfordian. Nevertheless, there is a possibility, however improbable it may be, thatAmmonites crenata Bruguière andAmmonites crenatus Oppel are synonyms. Therefore it is proposed here to retain the current usage of the namescrenatus Bruguière emend. d’Orbigny (1847) andrenggeri Oppel.

Reappraisal of the latest Albian (Mortoniceras fallax Zone) cephalopod fauna from the classical Salazac locality (Gard,southeastern France)

The Salazac locality (Gard, southeastern France) is renowned for the richness of its cephalopod fauna (especially ammonites) from the Mortoniceras fallax Zone (uppermost Albian, Lower Cretaceous). However, most ammonite species have paradoxically been scarcely illustrated up to now. Furthermore, the rare assessments of ammonite taxonomic diversity are presumably inaccurate, as they either result from a drastic typological approach or could not benefit from the most recent advances in modern concepts of ammonoid intraspecific and ontogenetic variations. In this work, we document an original cephalopod assemblage from Salazac represented by abundant, well-preserved specimens (564 studied ammonites, including ca. 50% of heteromorphs) constituting a high diversity. The sample size and quality of this new material allowed some extensive morphological and biometric analyses whenever possible (i.e., for subdatasets in which a significant number of measurements is available) and to thoroughly assess intraspecific and ontogenetic variations for a few species. This led to determine the diagnostic value of various shell characters commonly used to characterize both well-documented and poorly-defined species. In particular, we show that a significant part of the variation in the number of ribs per whorl within the heteromorphic genera Mariella and Turrilitoides is directly related to shell size and that the strength of tubercles covaries negatively with the number of ribs in Mariella, therefore challenging the diagnostic value of these characters. We further suggest that rib density covaries with whorl shape in Mariella, following Buckman’s first rule of covariation. In total, one species of nautilid and 38 taxa (25 genera) of ammonites are described, among which five species are documented from Salazac for the first time. In turn, this study provides valuable data for future phylogenetic, biostratigraphical, biogeographical and broad-scale diversity studies.     

Evolutionary trends in Mio-Pliocene Leporinae, based onTrischizolagus (Mammalia, Lagomorpha)

New material ofTrischizolagus dumitrescuae from Moldova and Ukraine is described. The variation of p3 inTrischizolagus shows the gradual shift of morphotype frequencies from the ‘Hypolagus’ pattern in Turolian through the mixture of three patterns (including ‘Nekrolagus’ morphotype) in Early Ruscinian to the dominant ‘Alilepus’ pattern in the Late Ruscinian samples. These transformations took place parallel to that of the North AmericanNekrolagus. Probably North AmericanSylvilagus, Brachylagus, andRomerolagus had an North American origin fromNekrolagus, whereas Eurasiatic and AfricanOryctolagus, Caprolagus, Nesolagus, andPoelagus could have originated in the Old World fromTrischizolagus.
