Keywords: Editorial

https://doi.org/10.18563/pv.9.ext.1-13

  Abstract

    Monsieur René Lavocat, Directeur du Laboratoire de Paléontologie des Vertébrés de la troisième section de l'Ecole Pratique des Hautes Etudes, quittait le service actif en l'année 1979.
    Cela fait maintenant quinze ans que fut installé à Montpellier, le laboratoire de Paléontologie des Vertébrés de l'Ecole Pratique des Hautes Etudes. La décision de M. René Lavocat a été particulièrement heureuse dans ses conséquences. Il a en effet permis le développement de l'enseignement et de la recherche en Paléontologie des Vertébrés à l'Université de Montpellier où se créa un des centres importants de cette discipline, en France. Il suscita la création de nouveaux laboratoires de l'Ecole Pratique des Hautes Etudes installés dès leur origine à Montpellier, ainsi que le déplacement à Montpellier d'un Laboratoire de l'Ecole Pratique, préexistant. Ce groupe de laboratoires constitue maintenant l'Institut de Montpellier de l'Ecole Pratique des Hautes Etudes.

Palaeotis weigelti restudied : a small middle Eocene Ostrich (Aves : Struthioniformes)
Peter Houde Logo and Hartmut Haubold
Published online: 20/06/1987

Keywords: Aves; Central Europe; Middle Eocene; Palaeotis; Struthioniformes

https://doi.org/10.18563/pv.17.2.27-42

  Abstract

    Palaeotis weigelti, from the Middle Eocene of central Europe, is a flightless, paleognathous bird. It appears to be a member of the ostrich lineage on the basis of trivial derived characters. It is a very primitive ratite, however, and does not possess any of the highly specialized cursorial adaptations that characterize the modern steppe -and savanna- dwelling ostriches.

Contributions à l'étude du gisement Miocène supérieur de Montredon (Hérault). Les grands mammifères. 2 - les carnivores
Gérard de Beaumont
Published online: 15/11/1988

Keywords: anatomy; Carnivora; France; Montredon; Systematics; Upper Miocene

https://doi.org/10.18563/pv.18.ext.15-42

  Abstract

    The locality of Montredon has provided 8 species of camivores, often little documented, that are discribed and depicted. All the remains are fragmentary and generally badly preserved which lowers very much the possible precision of the taxonomic study; this one has however allowed the creation of a new subspecies. The most richlypdocumented forms are an ursid (Indarctos) and a felid (Machairodus). Issuing often from a westem Europe evolution, the carnivores are well inserted between those of the better known faunas of the "Classical Pontian" and of the lower Vallesian and this situation fits also well with their stratigraphic level, that cannot however be more accurately defined with them alone.

Long-term fidelity of megaoolithid dinosaurs to a large breeding-ground in the Upper Cretaceous of Aix-en-Provence (southern France).
Géraldine Garcia Logo, Yves Dutour, Isabellle Cojan, Xavier Valentin Logo and Gilles Cheylan
Published online: 15/12/2003

Keywords: Large nesting ground; megaloolithid eggs; Southern France; Upper Cretaceous

  Abstract

    We present here the preliminary results from a new nesting site "Sextius-Mirabeau", discovered close to the historical centre of Aix-en-Provence in Upper Cretaceous deposits. This extensive megaloolithid nesting ground, the first large scale excavation (3225 m²) in France, yielded more than 530 eggs, some organized in clusters. Their study reveals the reproductive strategy of the megaloolithid egglayer group which indicates nesting fidelity and gregarious behaviour.

The microfauna of the Djebel Qafze Cave
G. Haas
Published online: 15/09/1972

Keywords: Micromammals; Rodents

https://doi.org/10.18563/pv.5.5.261-270

  Abstract

    This study examines the microfauna from Djebel Qafze Cave, focusing on mammalian remains, with Microtus guentheri as the dominant species and a notable absence of Cricetinae (hamsters). The richest layers (XVIa, XVII, XVIII) suggest accumulation by raptors, particularly owls, given the high presence of nocturnal species like voles and shrews. Two significant species, Arvicanthis cf. ectos and the newly described Rattus (? Mastomys) nazarensis, are highlighted. Reptiles (gekkos, Ophisaurus) and birds are also present, while hedgehogs and lagomorphs are absent. The findings underscore the role of avian predators in fossil deposition and refine the chronology of regional Pleistocene fauna.

Contribution à l'étude des Cricétidés oligocènes d'Europe occidentale
Monique Vianey-Liaud Logo
Published online: 20/01/1972

Keywords: Cricetidae; Europe; Oligocene

https://doi.org/10.18563/pv.5.1.1-44

  Abstract

    Of the ten cricetid species from the Oligocene of Western Europe, attributed until now to the genus Eucricetodon, only four prove to be utilizable - E. atavus, E. huberi, E. praecursor, E. collatum - to which it is possible to add two forms newly described: E. huerzeleri and E. quercyi. The evolullon of the genus Pseudocricetodon is also the subject of new observations. The study of the dental morphology allows us to distinguish in these two genera three lineages beginning in the middle Oligocene:

    - Lineage P. montalbenensis-P. thaleri (from Montalban to Goderet), of small size, without
    increase in size.
    - LineageE. atavus-E. infralactorensis (from Hoogbulsel to Estrepouy), of middle size, with a regular increase in size.
    - Lineage E. huerzeleri-E. haslachense (level of Montalban to that of Estrepouy), of large size, with an increase in size.

    Two other forms are equally represented in these loealitles: Heterocricetodon aff. helbengi and Melissiodon quercyi. It has been possible to attribute a precise age (zone of "Cournon") to the last species, which has been defined by Schaub (l925) from material in the Old Quercy collections. The genera Pseudocricetodon, Eucricetodon, ? "Cricetodon", Leydimys, Eumys, differentiated at the beginning of the middle Oligocene in Europe, Asia and North America, seem to derive from a common ancestral group. The place of origin of this group could be situated in Asia.

Published online: 15/11/1974

Keywords: Aubrelong; Quercy Phosphorites

  Abstract

    L’article analyse les poches à phosphorite d’Aubrelong (Quercy), comparant les fouilles de 1937 (Éocène supérieur) et celles des années 1967-1970 (Oligocène inférieur), révélant une stratification contrastée : argiles brunes pauvres en fossiles en surface, et argiles rouges riches en phosphates et faune en profondeur. Les analyses géochimiques confirment une origine latéritique sous climat tropical humide, avec des remplissages tantôt stratifiés, tantôt chaotiques, remettant en cause l’hypothèse d’une progression chronologique uniforme des dépôts

Multituberculate endocranial casts
Zofia Kielan-Jaworowska Logo
Published online: 30/06/1983

Keywords: Allotheria; Cretaceous; endocranial cast; Mongolia; multituberculates

https://doi.org/10.18563/pv.13.1-2.1-12

  Abstract

    A reconstruction of a multituberculate endocranial cast is made on the basis of a complete natural cast prepared from the skull of Chulsanbaatar vulgaris, and other less complete endocasts, all from the Late Cretaceous of Mongolia. The multituberculate endocast is of mammalian pattern but it has retained a therapsid-like lateral profile with a deep rhombencephalon and a shallow telencephalon. It is characterized by: a heart-shaped cross-section of the telencephalon; an extensive lissencephalic neocortex; a very prominent pons placed far anteriorly; a lack of cerebellar hemispheres, and very large paraflocculi. Its structure, very different from the brains of other mammals, suggests thats the Multituberculata branched very early from the main mammalian stock. This supports Simpson's (1945) idea that the Multituberculata should be placed in a subclass of their own: Allotheria MARSH. The endocast and braincase structure show that the Multituberculata had strongly developed senses of smell and hearing. The encephalization quotient of approx. 0.55 evaluated for Ch. vulgaris is relatively high for a Mesozoic mammal.

Rongeurs du Miocène inférieur et moyen en Languedoc. Leur apport pour les correlations Marin-Continental et la Stratigraphie.
Jean-Pierre Aguilar
Published online: 31/03/1980

Keywords: Languedoc; Miocene; Rodents; Southern France

https://doi.org/10.18563/pv.9.6.155-203

  Abstract

    The rodents (Cricetidae, Gliridae, Sciuridae) found in lacustrine, brackish marine and karstic sediments of Miocene age in Languedoc, assign the position of the different localities in the scale of "niveaux repères" used by mammalogists. Some detailed stratigraphical studies bring several correlations between this continental biochronological scale and the marine scale ; the most important results are the Aquitanian age of the "niveaux repères" of Coderet and Paulhiac, the Burdigalian age of Laugnac, Estrepouy, Vieux-Collonges, La Romieu and Sansan and the Langhian or Lower Serravallian age of La Grive M. The correlations between the Tethys and the Central Paratethys for the Lower Neogene profit also of these results, since the locality of Neudorf Spalte 1, 2 (Czechoslovakia) is shown to be younger than Sansan (France). The paleontological study has also several geological inferences for the Miocene of Languedoc ; with the calibration of this Miocene, we know quite precisely that the Lower Miocene is chiefly a time lacustrine sedimentation, and also that the marine Miocene sedimentation ends early in the Miocene Period, in Langhian or lower Serravallian times.

Additions to the elasmobranch fauna from the upper Cretaceous of New Jersey (middle Maastrichtian, Navesink Formation)
Gerard R. Case and Henri Cappetta Logo
Published online: 15/12/2004

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).

Published online: 16/12/2008

Keywords: Algeria; Brezina; El Bayadh; Ichnites; Lower Cretaceous; Sauropoids; Theropoids

https://doi.org/10.18563/pv.36.1-4.7-35

  Abstract

    Evidence of 350 Lower Cretaceous Dinosaur footprints is pointed out in El Bayadh area. Their preliminary study allow to distinguish four trackway assemblages which reveal vertebrate bipedal presence forms of tri-and tetradactylous Dinosauroïds (Assemblages 1-3) and quadrupidal Sauropoïd (Assemblage 4).

    The analysis of their footprint biometric features will attribute the quadrupidal Sauropoïd form to Brontopodus ichnogenus which is weIl known in the Jurassic and Cretaceous periods. In retum and despite their age, the dinosauroïd forms were approached, temporarily, to Grallator and Eubrontes types.

    The occurrence of the dinosaur traces (Theropoïd and Sauropoïd) constitutes, in the Lower Cretaceous, an important first step of the knowlege of the marshy Reptilian fauna which takes over, from the begining of the Secondary Era, a wide paleogeographie area on the Southem Tethyan margin.

A late Eocene palaeoamasiine embrithopod (Mammalia, Afrotheria) from the Adriatic realm (Island of Rab, Croatia)
Fabrice Lihoreau Logo, Ljerka Marjanac, Tihomir Marjanac Logo, Ozan Erdal Logo and Pierre-Olivier Antoine Logo
Published online: 14/12/2023

Keywords: Balkanatolia; Grande Coupure; Great Adria; Paleobiogeography; Systematics

https://doi.org/10.18563/pv.47.1.e1

  Abstract

    A cheek tooth recently unearthed in the Lopar Sandstone unit, of late Eocene age, in the northern part of Rab Island, Croatia, is one of the very few Eocene mammalian remains found in the Adriatic area. Thorough comparison of this tooth with those of Old-World Palaeogene mammalian orders suggests that it is a M3 belonging to an embrithopod afrothere. The specimen is referred to as Palaeoamasia sp. This genus was formerly known only in Eocene deposits of Anatolia but with close relatives in Romania among Palaeoamasiinae. The geographical distribution of this subfamily perfectly matches the recently-named Balkanatolian landmass, which experienced in-situ evolution of endemic mammals prior to the Grande Coupure event that occurred around the Eocene–Oligocene transition. This last event is characterised by massive Asian immigration in Western Europe and the supposed extinction of many endemic Central and Western European mammals, including Palaeoamasiinae.

Small sauropod tracks in the Hettangian of Southern France – A case of ichnite fossilization in an intertidal zone
Pierre Demathieu, Alain Izart, André Charrière Logo and Monique Vianey-Liaud Logo
Published online: 28/06/2022

Keywords: Intertidal zone; Lower Jurassic; Sauropods; Southern France; Tracks

https://doi.org/10.18563/pv.45.2.e1

  Abstract

    This paper presents the description and the interpretation of recently discovered traces on a Lower Hettangian dolomitic outcrop in the Bédarieux area, Southern France. One trace set immediately attracted the attention by its resemblance to a small sauropod pes-manus couple but no trackway was visible. As the other traces have a variety of shapes with no obvious significance, it took a thorough examination of the 3D and sedimentological data to come to the conclusion that most traces likely were sauropod tracks made under diverse conditions. Sedimentological and ichnological data indicate that the tracks have been made in the intertidal zone of a carbonated tidal flat shortly before an emersion period. It appears that that the variety of trace shapes is due to a variety of water depths: the sauropods were punting when the water level was high. The lack of trackways seems due to the combination of an underprint situation, buoyancy effects and the small size of the track-bearing slab. Several hypotheses can be considered for explaining the very small size of the tracks, such as insular dwarfism or the immaturity of the trackmakers.

Die Ohr-Region der Paulchoffatiidae (Multituberculata, Ober-Jura).
Gerhard Hahn
Published online: 15/11/1988

Keywords: Multituberculata; Ober-Jura; Paulchoffatiidae; Petrosum; Portugal

https://doi.org/10.18563/pv.18.3.155-185

  Abstract

    The petrosal of the Paulchoffatiidae HAHN, 1969 is described and compared with that of younger multituberculates and of other Mesozoic mammals. The "Morrison petrosal", described by Prothero (1983), is also discussed; it probably belongs to the multituberculates. The reconstruction of the ventral side of the Paulchoffatiinae-skull, given by Hahn in 1987, is completed by addition of the otic and the occipital region.

 La poche à phosphate de Ste-Néboule (Lot) et sa faune de vertebres du Ludien supérieur. 9- Primates et Artiodactyles
Jean Sudre
Published online: 25/09/1978

Keywords: Eocene; Quercy Phosphorites

https://doi.org/10.18563/pv.8.2-4.269-290

  Abstract

    La faune d'artiodactyles de Ste-Néboule, qui comprend neuf espèces, présente de nombreux
    points communs avec les faunes habituellement rattachées au Ludien supérieur, telles celles de La Débruge ou de Montmartre. A l'inverse de ces localités, on ne connaît pourtant, à Ste-Néboule, ni Oxacronae, ni Anoplotheriinae. Parmi les espèces du gisement se trouve une nouvelle espèce du genre Mouillacitherium (M. schlosseri n. sp.), cette forme devant être interprétée comme le dernier représentant du rameau. Nous faisons connaître par ailleurs la presque totalité de la denture du Dacrytherium saturninii, espèce qui était à ce jour très imparfaitement documentée. Ste-Néboule est, d'autre part, la seule localité où l'on peut signaler l'association probable de deux lignées du genre Amphimeryx. Les primates sont peu diversifiés à Ste-Néboule, puisque le groupe est limité au seul genre Adapis. Les genres Microchoerus et Pseudoloris, que l'on sait pourtant être représentés dans des gisements dâge voisin (Microchoerus ornatus à San Cugat de Gavadons et Mormont-Entreroches, Pseudoloris reguanti à San Cugat de Gavadons, Pseudoloris cf. reguanti à Neustadt ; cf. Louis et Sudre 1975) sont absents dans les faunes du Quercy de cette période.

Les Issiodoromyinae (Rodentia, Theridomyidae) de l'Eocène supérieur à l'Oligocène supérieur en Europe occidentale
Monique Vianey-Liaud Logo
Published online: 15/05/1976

Keywords: climate; Faunal turnover; Paléogène

https://doi.org/10.18563/pv.7.1-2.1-115

  Abstract

    Based on material from 30 localities, morphologic dental, cranial and biometric analyses have permitted the characterization of two parallel Issiodoromyine lineages, and also the definition of diverse species representing several evolutive stages. Thus it is that new lineages complete the contribution made by the Theridomyinae and Cricetidae and permit, for the Quercy in particular, additional precision in the biochronologic succession of the localities. One of the lineages is limited to the genus Pseudoltinomys LAVOCAT; the other evolves from the genus Elfomys HARTENBERGER to the genus Issiodoromys BRAVARD in GERVAIS. The latter is affected by profound anatomical changes due to a functional modification of the mastication apparatus. These changes seem to be able to be put in relation with the aridification and cooling of the climate at the end of the Eocene. At the end of the middle Oligocene, a new chewing structure is achieved. It is found in diverse living rodents that inhabit a rather arid steppe environment (Cavia, Pedetes, Ctenodactylus). To these supposed nearby ecologic conditions, these rodents have responded in a convergent fashion. It is possible to attribute to the extreme specialization of Issiodoromys its incapacity to adapt to the new climatic crisis of the end of the Oligocene. The arrival of immigrants may be considered as another cause of its disappearance at this time, complementary or not with the first.

  Abstract

    About the early radiation of Rodents, we have now from the early tertiary of Asia, a new fossil record, and we can do new interpretations. First the problem of the origin of Rodents is studied : considered as a sister group of Lagomorpha, it is possible to find their ancestors between the Mixodontia. Second the new facts about the origin of modern groups of Rodents are reviewed. A general scheme of this diversification can be proposed.

  Abstract

    New and hitherto unpublished mammals from the stratigraphical levels Unterkohle, Untere Mittelkohle and Obere Mittelkohle of the Geiseltal near Halle, GDR, are described (= biochronological levels MP 11-13, Geiseltalian sensu Franzen & Haubold 1986a, b). The marsupial taxa Amphiperatherium aff. maximum (MP 12), A. goethei (MP 12), and Peratherium aff. monspeliense (MP 12 and 13) are recorded for the first time. A lectotype for Amphiperatherium giselense is designated, and the alleged primate Microtarsioides voigzi is assigned to Marsupialia, incertae sedis. A new insectivore species, Saturninia ceciliensis n. sp., is described (MP 13). The anteater Eurotamandua joresi is recorded for the first time outside its type locality, Grube Messel, FRG (MP 11). The present humerus and ulna display the autapomorphic features of the myrmecophagids.
