New Squalicorax species (Neoselachii: Lamniformes) from the Lower Maastrichtian of Ganntour phosphate deposit, Morocco
Henri Cappetta, Sylvain Adnet, Driss Akkrim and Mohammed Amalik
Keywords: Anacoracidae; Chondrichthyes; Maastrichtian; Morocco; New taxa

doi: 10.18563/pv.38.2.e3
 
  Abstract

    Two new Squalicorax species, S. benguerirensis nov. sp. and S. microserratus nov. sp. are described from the Lower Maastrichtian of the Benguérir phosphate open mine, Ganntour deposit, Morocco. The species S. benguerirensis nov. sp. was classically assigned to S. yangaensis since Arambourg (1952) and has been also recognized in coeval deposits from eastern USA to Mid-East. The species S. microserratus nov. sp. correspond to the lateral teeth of S. kaupi as reported by Arambourg (1952) and which is now referred in fact to S. bassanii. The comparison of these two new species with other Anacoracids, known in Moroccan or elsewhere, allows highlighting the great taxonomic and ecological diversities of this family during the Cretaceous.

Angolabatis nom. nov.,a replacement name for the Cretaceous genus Angolaia Antunes & Cappetta, 2002 (Chondrichthyes: Rajiformes), a preoccupied name.
Miguel T. Antunes and Henri Cappetta
Keywords: Angola; Campanian/Maastrichtian; homonymy; Hypsobatidae; nomen novum; Rajiformes
 
  Abstract

    In 2002, Antunes & Cappetta published several new taxa (genera and species) in a paper on Cretaceous elasmobranch faunas from Angola. One of the new genera was named Angolaia (Rajiformes, Hypsobatidae; type-species: Angolaia benguelaensis Antunes & Cappetta, 2002, Late Campanian/Early Maastrichtian of Angola). Recently, Dr. Christian Kammerer kindly informed us that the genus Angolaia was preoccupied by a cicadellid homoptere (Insecta), published by Linnavuori & Al-Ne'amy, 1983. So, according to mIes of the International Code of Zoological Nomenclature (ICZN 1999, articles 52, 60) this name became unavailable. Consequently, the Rajiformes genus Angolaia is a junior homonym, invalid and must be rejected. In replacement, we propose the new name Angolabatis

Additions to the elasmobranch fauna from the upper Cretaceous of New Jersey (middle Maastrichtian, Navesink Formation)
Gerard R. Case and Henri Cappetta
Keywords: Elasmobranchs; New Jersey; new species; Upper Cretaceous; USA
 
  Abstract

    A recently discovered, almost complete specimen of a hybodont tooth, allows us to describe as a new species, fairly common, but usually fragmentary teeth in the Navesink Formation of New Jersey: Hybodus novojerseyensis nov. sp.
    Three additional taxa are also described : Heterodontus creamridgensis, Squalicorax sp. and Pseudocorax affinis which is noted for the first time in North America.
    The whole elasmobranch fauna of the Early Maastrichtian localities of New Jersey is reevaluated and several generic assignments are changed in comparison to the list previously published in 1975 (Cappetta
    & Case).

First record of dinosaur eggshells and teeth from the north-west african Maastrichtian (Morocco).
Géraldine Garcia, Rodolphe Tabuce, Henri Cappetta, Bernard Marandat, Ilhem Bentaleb, Aziza Benabdallah and Monique Vianey-Liaud
Keywords: Africa; amniotic eggshells; Maastrichtian; Morocco; theropod teeth
 
  Abstract

    We report the discovery of amniotic eggshells and theropod teeth from the Late Cretaccous  period in Morocco.The megaloolithid family represents the only known dinosaur egg remains in the north part of Africa and attests indirectly to the occurrence of sauropod dinosaurs (titanosaurids) in the Maastrichtian of Africa.

First evidence of an early Miocene marine teleostean fish fauna (otoliths) from la Paillade.(Montpellier,France)
Bettina Reichenbacher and Henri Cappetta
Keywords: Aquitanian; Biostratigraphy; La Paillade; marine deposits; Miocene; otoliths; Palaeoecology; Palaeogeography; Southern France; Teleostei
 
  Abstract

    A fossil fish fauna, based on 5533 otoliths, from the La Paillade locality at Montpellier is described and figured. The otolith-bearing marls correlate to mammal zone MN l (Aguilar, 1982), and thus represent the earliest Miocene. The fish fauna consists of 30 taxa belonging to 20 families. Two species are new: Dussumieria sittigi and Liza gaudanti. The predominant faunal element is the Lesueurigobius vicínalis-species complex, composing 73% of all investigated otoliths. The palaeoecological analysis reveals a marine to euryhaline fish fauna living under tropical to subtropical conditions in the transition zone littoral - sublittoral. Water depth probably was more than 10 m. The scarcity of pelagic físhes suggests that the habitat was either a sheltered bay and/or far away from the open sea. Furthermore, some genera represented in the La Paillade fish fauna presently live exclusively in the Indopacific realm. Their presence strongly supports a broad connection between the Indian Ocean, the Mediterranean, and the Paratethys Seas during the Early Miocene (Aquitanian). From a palaeobiogeographical point of view, faunal relationships were found between the La Paillade fish fauna and both the Paratethys fish fauna and the fish fauna from the deposits in the Upper Rhinegraben and the Mayence and Hanau Basins (Germany).

Révision des Rhombodontidae (Neoselachii Batomorphii) des bassins à phosphate du Maroc
Abdelmajid Noubhani and Henri Cappetta
Keywords: Batomorphii; Maastrichtian; Morocco; New taxa; Phosphate; Rbombodontidae
 
  Abstract

    The revision of the Rhombodontidae from the Maastrichtian of Morocco led us to the description of a new species: Rhombodus andriesi.

    The biometrical study of populations of R. binkhorsti and R. microdon, species sometimes considered as synonymous, supports the conclusion that they represent two distinct species and not young and adult specimens of a single species. The stratigraphical range of these two species confirms this
    result.

    The reexarnination of type-series studied by C. Ararnbourg led us to revise the generic status of Rhombodus bondoni which is now ranged, because his dental features, in the new genus Dasyrhombodus showing a less derived dentition than Rhombodus. The stratigraphical range of each species is clarified within the phosphatic series.

Keywords: Editorial
 
  Abstract

    Editorial for celebrating the publication of the volume 20.

    La revue PALEOVERTEBRATA a été fondée en 1967 par Louis THALER, à une époque où il n'existait, au plan international, que deux périodiques uniquement consacrés aux vertébrés fossiles. Actuellement ce nombre n'est que de quatre. A l'origine la revue fut essentiellement créée pour diffuser les résultats des chercheurs du Laboratoire de Paléontologie de l'Université de Montpellier, alors en début d'expansion et plusieurs thèses et de nombreux travaux directement liés à des thèses y furent publiés ce qui n'excluait déjà pas la publication d'articles d'auteurs étrangers.

Hexanchiforme nouveau (Neoselachii) du Crétacé inférieur du Sud de la France
Henri Cappetta
Keywords: Hexanchiformes; New genera; Southern France; systematics; Valanginian
 
  Abstract

    The dentition of Welcommia bodeuri nov. gen. nov. sp. from the Valanginian of Southem France is described and reconstructed. Species and genera of Upper Jurassic and Lower Cretaceous Hexanchiformes are reviewed and discussed.
    The genus Notidanoides MAISEY, 1986 must be restricted to the single Nusplingen Upper Jurassic specimen, whose attribution to the species muensteri AGASSIZ, 1843 remains doubtful.
    The genus Paranotidanus WARD &THIES, 1987 that does not rest on any type-species nor on any precise dental characterization must be rejected.
    The genus Eonotidanus PFEIL, 1983, based on a very poorly preserved and heterogeneous type-material must also be rejected.
    Teeth from the Lower Cretaceous, with a peculiar morphology, previously assigned to Eonotidanus or to Notidanoides, are to be ranked in the new genus Pachyhexanchus

Types dentaires adaptatifs chez les sélaciens actuels et post-paléozoïques.
Henri Cappetta
Keywords: Dental types; evolution; Fossil selachians; Recent selachians; Trophic adaptations
 
  Abstract

    The dentition of selachians is characterized by an often very pronounced heterodonty involving a great morphological diversity. Despite this fact, the dentitions of selachians can be grouped in a rather reduced number of dental types corresponding to trophic adaptations: grasping, tearing, cutting, crushing, grinding and grasping-grinding type. The numerous exemples of convergence and parallelism that can be observed in fossil selachians and between Recent and fossil ones is the result of this reduced number of dental types. These dental specialisations allow to try a reconstruction of the way of life of fossil forms.

Les Otolithes de téléostéens du Miocène de Montpeyroux (Herault),France).
Dirk Nolf and Henri Cappetta
Keywords: Miocene; Montpeyroux; Otolithes; teleostean fish
 
  Abstract

    Sieving and washing of about 700 kg of sediment from the miocene site at Montpeyroux produced otoliths of 34 teleost species, of which four still occur in the present day fauna or are near to extant species. Among the fossil species, eight are new : Ilisha lerichei, «genus Clupeidarum ›› orbiculatus, Dipulus mediterraneus, Morone cornuta, Chanda nelsoni, Pomadasys steurbauti, «genus Sciaenidarum ›› barthassadensis and Paraplagusia roseni. The fauna found is typical for a tropical or subtropical very littoral, probably even estuarine environment; it was living in a period near the boundary between Lower and Middle Miocene, perhaps somewhat earlier.

Modification du statut générique de quelques espèces de sélaciens crétacés et tertiaires
Henri Cappetta
Keywords: Cretaceous; Selachians; Tertiary
 
  Abstract

    The re-examination of six fossil selachian species has involved the creation of six new genera: Squatiscyllium, Protolamna, Parotodus, Abdounia, Physogaleus, Hypolophodon and of one new species : Prozolamna sokolovi. The modification of the generic statute of these species allows to clarify their systematic position and to define their relationships at a familial level.

Les poissons crétacés et tertiaires du bassin des Iullemmeden (République du Niger)
Henri Cappetta
Keywords: Actinopterygians; Cenozoic; Cretaceous; Dipnoans; Selachians
 
  Abstract

    The present work is devoted to the study of the Cretaceous and Tertiary fishes (teeth of Selachians, Actinopterygians and Dipnoans) collected during a recent expedition in Niger. The Maestrichtian localities have yielded a new genus and a new subspecies of Selachian: Igdabatis sigmodon nov. gen., nov. sp. and Lamna biauriculata nigeriana nov. subsp. The locality of Sessao, which has been attributed to the Thanetian by means of the study of the fish, has furnished by screen-washing an interesting fauna wherein six new species are described: Raja Iouisi, Dasyatis sessaoensis, D. sudrei, D. russelli, Hypolophites thaleri and Ceratodus casieri. Comparison of these faunas with contemporary faunas of Africa has brought out a certain endemism in the Iullemmeden Basin during the late Cretaceous and the early Tertiary.

Les sélaciens du Miocène de la région de Montpellier
Henri Cappetta
Keywords: Ichtyofauna; Miocene; Montpellier

doi: 10.18563/pv.3.ext.1-139
 
  Abstract

    The utilization of screen-washing and attack by dilute acetic acid has permitted the collecting, in the Miocene of the department of Hérault (France), of a very rich ichthyofauna. This fauna is presently comprised of about 60 studied species, of which 11 are new, and represents, in the present state of knowledge, the most varied Miocene selachian fauna described in the world.
    The abondance of material has allowed an overall revision to be made; it has thus been possible to complete the description and the figuration of species that were poorly known until now, and to synonymize species that were established on simple morphotypes. Paleo-ecologic study of the ichthyofauna has permitted conclusions to be drawn relative to climate and bathymetry; it was thus possible to show that the Miocene fauna of Hérault was a fauna of a subtropical sea, essentially neritic with rare pelagic contributions.
    Knowing the stratigraphic position of the localities, it has been possible to distinguish three faunal assemblages based on associations of species. Some hypotheses on the evolution of certain lineages have been expressed.
    The comparison of this fauna with that of other regions permitted the relationships of two diflerent faunal provinces to be specified: the first belongs to the northern domain, characterized by a fauna still subtropical but with numerous temperate water elements; the leoond belongs to the Mesogean domain characterized by warm water forms. It has also lhovm that contemporary faunas could be very different according to the bathymetric zone in which they lived, which furnishes valuable information for the paleogeographic reconstruction of sedimentary basins.
