Contributions à l'étude des micromammifères du gisement Miocène supérieur de Montredon (Hérault). 1- Le gisement
Jean-Pierre Aguilar and Jean-Yves Crochet
Published online: 30/06/1982

Keywords: Hérault; Late Miocene; Micromammals; Montredon

https://doi.org/10.18563/pv.12.3.75-79

  Abstract

    La localité fossilifère du Puech de Montredon, désignée plus communément sous le nom de Montredon, est située sur la commune de Montouliers (Hérault) à quelques 300 mètres de la limite avec le département de l'Aude. Elle a été découverte en 1845 par Narbonne, Directeur des Mines de La Caunette, et de très nombreux restes de vertébrés continentaux y ont été extraits. La plus ancienne mention de ce gisement dans la littérature semble être celle de Lartet (1859) qui signale que "M. Jourdan, de Lyon, a constaté à Montredon, près de Bize (Aude), l'association des restes de Dinotherium avec l'Hipparion".

An Australian Miocene Brachipposideros (Mammalia, Chiroptera) related to Miocene representatives from France
Bernard Sigé, Suzanne J. Hand Logo and Michael Archer Logo
Published online: 15/12/1982

Keywords: Australia; bats; Chiroptera; Miocene

https://doi.org/10.18563/pv.12.5.149-172

  Abstract

    A new middle Miocene hipposiderid bat is described from a limestone deposit on Riversleigh Station in north-western Queensland. Hipposideros (Brachipposideros) nooraleebus n. sp. is the first record of this subgenus from anywhere in the world outside of France. The palaeoecological setting of the fossil bats appears to have been a relatively quiet, sunny lime-enriched tropical pool that contained tortoises, crocodiles and fish. It is possible that the bats were washed into the pool from an adjacent cave.
    The Riversleigh bat most closely resembles the French Burdigalian (early middle Miocene) bat H. (B.) aguilari. It is also possible that it may have been closely related to the original Australian hipposiderid stock that ultimately gave rise to the endemic monotÿpic Rhinonycteris aurantius. The disjunct distribution of species of H. (Brachipposideros) suggests that representatives of this subgenus will be found in at least tropical southern Asia.

Présence de Palaeobatrachidae (Anura) dans des gisements tertiaires Français caractérisation, distribution et affinités de la famille
Colette Vergnaud-Grazzini and Robert Hoffstetter
Published online: 15/05/1972

Keywords: Anura; Palaeogeography; Systematics

https://doi.org/10.18563/pv.5.4.157-177

  Abstract

    The Palaeobatrachidae until now have not been reported from France. The present note makes known the discovery of very significant remains in three Tertiary localities of France: Cernay (late Paleocene), Laugnac (late Aquitanian) and Sansan (middle Helvetian). The osteologic characters, as well as the geographic and stratigraphic distribution of the family are re-stated with added details. The Palaeobatrachidae are a European family known from the late Jurassic of Catalonia (publication in course by J. Seiffert) to the Plio-Pleistocene (pre-Mindel) of Poland and Rumania. By their way of life and certain osteologic characters they are similar to the Pipidae, but they are distinguished by profound differences. It would be rash to include them in the Pipoidea or even in the Aglossa. They are apparently an independant group, essentially holarctic, which held in Europe a role equivalent to that played by the Pipidae south of Tethys.

Les poissons crétacés et tertiaires du bassin des Iullemmeden (République du Niger)
Henri Cappetta Logo
Published online: 15/09/1972

Keywords: Actinopterygians; Cenozoic; Cretaceous; Dipnoans; Selachians

https://doi.org/10.18563/pv.5.5.179-251

  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.

Mode de vie et affinités de Paschatherium (Condylarthra, Hyopsopontidae) d'après ses os du tarse
Marc Godinot Logo, Thierry Smith Logo and Richard Smith
Published online: 16/12/1996

Keywords: Astragalus; Calcaneum; Condylarthra; Eocene; Functional morphology; Paschatherium; PHYLOGENY

  Abstract

    Tarsals that can be confidently attributed to Paschatheríum dolloi from Dormaal (Belgium) are described. The astragalus is short; its broad neck is set at an angle of 30 degrees to the trochlea. The trochlea is pulley-shaped and proximally extended. There is no astragalar foramen. The medial tibial facet extends distally in a cup deeply excavated in the neck and buttressed. The sustentacular facet extends toward the navicular facet but is not fully confluent with it. The calcaneum bears a proximo-distally extended proximal facet for the astragalus. A relatively large peroneal tubercle projects from the body, and is situated distally. Functionally, the trochlea indicates extensive flexion-extension movements of the foot. Calcaneo-astragalar facets indicate sliding and rotation between the two tarsals. The inclination of the navicular facet suggests frequent foot inversion. The peroneal tubercle reflects good muscular capacities for foot rotation. Overall morphology is interpreted as a scansorial adaptation similar to that of sciurids.Comparisons are made with the tarsals of Macrocranion vandebroeki from Dormaal and Hyopsodus paulus from the Bridgerian of Wyoming. Some similarities between the astragali of Paschatherium and Macrocraníon (trochlea) are interpreted as convergences for rapid locomotion. However absence of mobility at the lower ankle and midtarsal joints in M. vandebroekzi suggests that this species was cursorial, as is known for M. tenerum from Messel. Similarities in the calcanea of Paschatherium and Hyopsodus are probably the result of close phylogenetic relations, and confirm the placement of Paschatherium in the hyopsodontids. The differences in the calcanea of Paschatherium and Macrocranion underline that Paschatherium is distinct from erinaceomorph insectivores. The differences in astragalar morphology between Paschatherium and Hyopsodus show that a marked adaptive divergence separates the two genera. We speculate about the common occurrence of a deep tibial cup (“cotylar fossa”) and a pulley-shaped trochlea in Paschatherium and hyracoids, suggesting that an adaptive scenario similar to that having led to Paschatherium (scansoriality) might explain the acquisition of the peculiar hyracoid tarsal characters; such a scenario contradicts the concept of Pantomesaxonia. Other peculiar characters of Hyopsodus suggest that hyopsodontids might be given more consideration in the search for hyracoid (and tethythere) origins.

Schmelzmikrostruktur in den inzisiven alt-und neuweltlicher histricognather nagetiere
Thomas Martin
Published online: 15/12/1992

Keywords: Africa; Caviomorpha; Ctenodactyloidea; Deseadan; Enamel microstructure; Hunter-Schreger bands; Hystricognathi; Incisors; Ischyromyoidea; multiserial; Paleobiogeography; pauciserial; Phiomorpha; Rodentia; South America

  Abstract

    Enamel microstructure in the incisors of Old- and New World hystricognath rodents:

    The incisor enamel microstructure in more than 100 genera of fossil and Recent hystricognath and sciurognath rodents was studied. A multiserial schmelzmuster is present in the Hystricognathi, the Ctenodactylidae, advanced Chapattimyidae, and in Pedetes. A redefinition of pauciserial and multiserial HSB is given that makes the two enamel types unambiguously distinguishable which apparently represent well defined evolutionary levels. In the pauciserial Schmelzmuster the IPM is thicker than in the multiserial one. In pauciserial HSB the IPM always surrounds each prism, and the crystallites of the IPM run parallel to prism direction; transition zones between HSB are lacking; the inclination of the HSB is normally very low and the prism cross sections are not flattened but somewhat irregular. The number of prisms per HSB is no good distinctive character for pauciserial and multiserial HSB, since there exists a wide overlap. The pauciserial schmelzmuster is primitive, the multiseiial derived because: 1. the pauciseiial schmelzmuster appears earlier in the fossil record in the most primitive rodents (Paramyids s.l. and Ctenodactyloids); 2. the Eocene Ctenodactyloidea show pauciserial HSB but the Oligocene and younger ones are characterized by multiserial HSB; 3. in the outgroup comparison, the Eurymylidae (Mixodontia) show pauciserial HSB; 4. biomechanically, multiserial HSB strenghten the enamel better than pauciserial HSB, since their IPM runs nearly always in an angle of 45° or more to the prisms.

    In multiseríal HSB three subtypes can be distinguished which are differentiated by the IPM orientation. Primitive is a (rarely strict) parallel or acute angular, anastomozing IPM, and derived is an interrow sheet-like ("plattenartige") IPM. This evolutionary polarity is indicated by enamel evolution in the Ctenodactylidae which show an acute angular IPM in the Oligocene and a rectangular interrow sheet-like IPM since the Miocene. Among the Caviomorpha a rectangular interrow sheet-like IPM is restricted to the Octodontoidea; therefore they must be considered derived in terms of their enamel structure. The first multiserial HSB in rodent incisors appear in phiomyids or chapatrimyids from the Upper Eocene of Algeria. The IPM is acute angular and anastomozing. The worldwide next younger multiserial HSB are found in Lower Oligocene phiomyids of Fayum, Egypt There already a rectangular interrow sheet like IPM is present (in Metaphiomys) besides the acute angular anastomozing IPM.

    The first Caviomorpha from the Deseadan (Oligocene-Miocene) likewise show already acute angular anastomozing IPM (e.g. Scozamys) and rectangular interrow sheet-like IPM (Platypittamys). Therefore the first Caviomorpha cannot be positioned close to a transition from pauciserial to multiserial HSB. In none of the potential caviomorph ancestors from southern North America multiserial HSB or transitional stage between pauciserial and multiserial HSB could be found. The similarities between the enamel types of the Fayum rodents and the rodents from the Deseadan of South America make a derivation of the Caviomorpha from Paleogene North African phiomorph rodents or their direct ancestors most probable. This supports at the same time a descent of the platyrrhine Primates from North African anthropoids.

Octodontid-like Echimyidae (Rodentia) : an upper Miocene episode in the radiation of the family
Diego H. Verzi Logo, Maria G. Vucetich Logo and Claudia I. Montalvo Logo
Published online: 20/05/1994

Keywords: Argentina; Echimyidae; Miocene; New taxa; Rodentia; South America

  Abstract

    Reigechimys octodontiformis gen. et sp. novo and R. plesiodon sp. novo are described. They represent the frrst record of the family Echimyidae for the Cerro Azul Formation (Huayquerian Age, Late Upper Miocene) at La Pampa Province, central Argentina. Both species have hypsodont cheek teeth with an eight-shaped occlusal design. This dental morphology represents a noticeable case of convergence to octodontids and indicates that these echimyids inhabited open environments.

Relations phylétiques de Bachitherium filhol, ruminant de l'Oligocène d'Europe Occidentale.
Denis Geraads Logo, Geneviève Bouvrain and Jean Sudre
Published online: 20/06/1987

Keywords: Artiodactyla; Bachitherium; Cladistic analysis; France; Mammalia; Oligocene; Ruminantia

  Abstract

    A detailed comparative study of a complete skeleton of Bachitherium and a cladistic analysis of the sub-order Neoselenodontia lead us to propose a cladogram and a new classification of this group. The Tylopoda are the sister-group of the Ruminantia, which are chiefly defined by the fusion of the cuboid and navicular. Within this infra-order, Amphimeryx is the sister genus of a tetraselenodont group, in which the Hypertragulidae are well-separated group from a monophyletic group defined by the loss of trapezium, fusion of capitatum and trapezoid, and the isolation of the hypoconid on lower molars. The most primitive genera of this group, Lophiomeryx and Iberomeryx still have an open trigonid on the lower molars, but this is lingually closed in Archaeomeryx, sister-genus of the higher Ruminantia which have fused metatarsals and more evolved milk teeth. We divide them into two pan/orders : Tragulina (including the recent and miocene Tragulidae, and the North-American Leptomerycidae), and Pecora, with reduced lateral metacarpals and a new crest (telocristid) on the lower premolars. Within the Pecora, the upper molars of Gelocus are more primitive than those of Bachitherium (a genus with many autapomorphies in the dentition) itself more primitive than the group Prodremotherium + Eupecora, with fused metacarpals. We consider the Eupecora (including several genera without frontal appendages) to be monophyletic.

Artiodactyla aus den Eozänen Braunkohlen des Geiseltales bei Halle (DDR)
Jorg Erfurt and Hartmut Haubold
Published online: 04/12/1989

Keywords: Artiodactyles; Eocene; Europe; Paleoecology; Stratigraphy; taxonomy

  Abstract

    The present study of Artiodactyla from the Middle Eocene of the Geiseltal lignite beds concems systematics, biostratigraphy, and palaeoecology on the basis of 174 specimens: isolated remains to more complete skeletons. Instead of the formerly known five species of two families are now recognized 14 species of the Diacodexeidae, Dichobunidae, Cebochoeridae, and Haplobunodontidae. New species are Aumelasia maniai, Anthracobunodon neumarkensis, Masillabune franzeni. Four species of the Geiseltalfauna are definitely known from elswere, and five species are closely related to those from other European localities. Evidently the faunal situation of artiodactyls during the Middle Eocene of Europe was largely uniform. The distribution of artiodactyls within the sequence of the Geiseltal strata corroborates the biostratigraphical concept of the land mammal age Geiseltalian (Franzen & Haubold l986b) as well as the mammalian reference levels MP 11-13 (Franzen 1987). Reconstructions of the skulls and skeletons allow conclusions on the functional morphology and palaeoecology of the artiodactyls of the European Middle Eocene

The Quaternary avifauna of Crete, Greece.
Peter D. Weesie
Published online: 01/09/1988

Keywords: Avifauna; Crete; Quaternary; Systematics

  Abstract

    Pleistocene bird fossils have been studied from nine localities on Crete. Part of this material was described earlier by the author (Weesie, 1982) and will not be treated here in extenso, the results will be incorporated. More than one third of the over 10,000 fossil bird bones available could be identified ; they were found to represent at least 65 bird species. The following species of the Pleistocene Cretan avifauna are new to the fauna of Crete : Branta ruficollis, Haliaeetus albicilla, Gyps melitensis, Aquila chrysaetos simurgh n. ssp., Ketupa zeylomensis, Aegolius funereus, Dendrocopos leucotos, Zoothera dauma, Turdus iliacus and Pyrrhula pyrrhula. The Pleistocene Cretan avifauna differs less from comparable mainland avifaunas than (fossil) avifaunas from oceanic islands do. Still, the Pleistocene Cretan avifauna has two qualities that are characteristic of island avifaunas : the almost complete absence of a group of birds (the Galliformes) and the presence of two endemic (sub)species : the giant eagle Aquila chrysaetos simurgh n. ssp. and the long-legged owl Athene cretensis (Weesie, 1982). The new subspecies is described in the present study.
    These endemic birds of prey were found in association with their supposedly principal prey species (now extinct as well) : endemic mice for the owl and endemic deer for the eagle. Endemic mammals have been found in association with endemic birds of prey on many islands, not only in the Mediterranean. There is evidence that the size of endemic birds of prey becomes optimally adapted to their feeding on certain endemic mammals, especially rodents. Another characteristic of the Pleistocene Cretan avifauna is the great number of species of birds of prey. This appears to be a common characteristic of fossil avifaunas from caves on Mediterranean islands as well as from caves on the European mainland. However, we think that ecological conditions on Pleistocene Crete (especially the abundant presence of mice) helped to account for the high representation of birds of prey. Furthemore, the fossil avifauna enables us to draw some conclusions about the climate and vegetation on Pleistocene Crete : it is concluded that the climate was cooler than today and that Crete was largely covered with forests. Finally, the reasons for the extinction or disappearance from Crete of some bird species of the Pleistocene Cretan avifauna are discussed.

  Abstract

    New dental and skeletal material referable to Palaeochiropteryx tupaiodon from the Middle Eocene locality of
    Messel (G.F.R.) is studied, which provides additions to the previously gained knowledge of this european genus. Dental specimens from Geiseltal (G.D.R.), also of Middle Eocene age, allow us to analyze Cecilionycteria prisca. Some of these are separated to establish a new genus, Matthesia, and two new species, M. germanica and M. ? insolita

La poche à phosphate de Ste-Néboule (Lot) et sa faune de vertebres du Ludien supérieur. 8- Insectivores et Chiroptères.
Bernard Sigé
Published online: 25/09/1978

Keywords: Eocene; Quercy Phosphorites

https://doi.org/10.18563/pv.8.2-4.243-268

  Abstract

    The small insectivorous placental mammals from Ste-Néboule are poorly varied. Two orders of insectivores are documented : the Proteutheria by Pseudorhyncocyon cayluxi (leptictids), the Lipotyphla by Saturninia gracilis and S. beata (nyctitheriids). The bats are only rhinolophoids and mostly hipposiderids. Sufficient populations allow us to restrict the original definitions of three previous species (Hipposideros schlosseri, Palaeophyllophora quercyi, P. oltina). From now, these species can be regarded as monophyletíc.

 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.

Angolabatis nom. nov.,a replacement name for the Cretaceous genus Angolaia Antunes & Cappetta, 2002 (Chondrichthyes: Rajiformes), a preoccupied name.
Miguel T. Antunes Logo and Henri Cappetta Logo
Published online: 15/10/2006

Keywords: Angola; Campanian/Maastrichtian; homonymy; Hypsobatidae; nomen novum; Rajiformes

https://doi.org/10.18563/pv.34.e13

  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

Rongeurs Miocènes dans le valles-Penedes 1 : Les rongeurs de Can Ponsic 1
Jean-Louis Hartenberger and Miquel Crusafont i Pairó
Published online: 20/04/1979

Keywords: Can Ponsic 1; Miocene; Rodents; Valles-Penedes

https://doi.org/10.18563/pv.9.1.1-15

  Abstract

    The rodents from the spanish locality of Can Ponsic 1 bring new data about some rodents species of the beginning of the Upper Miocene in South-West Europe. The criticims made by Mein and Freudenthal about the validity of the species Hispanomys thaleri from Can Llobateres are not justiíied. The study of the anatomy of the skull of Rotundomys from Can Ponsic 1 gives accurate information about the affinity of this genus with Cricetulus, and shows that the hypothesis, according to which Rotundomys is an ancestral form of the Arvicolids, is unlikely. The systematics of Heteroxerus and the phylogeny of the mio-pliocene Muscardinus species are also discussed. The Can Ponsic 1 locality is a little older than Can Llobateres.

Les mammifères Montiens de Hainin (Paléocène moyen de Belgique) Part1: Multituberculés.
Monique Vianey-Liaud Logo
Published online: 01/11/1979

Keywords: Belgium; Hainin; Mammals; multituberculates; Paleocene

https://doi.org/10.18563/pv.9.4.117-131

  Abstract

    The Montian locality of Hainin (Hainaut, Belgium) yielded about twenty teeth of Multituberculates. They are very peculiar forms, showing no affinities, at the generic level, with those hitherto known from North America, Asia and Europe. They are referred to the new taxa Boffius splendidus nov. gen., nov. sp., Hainina belgica nov. gen., nov. sp., and H. godfriauxi nov. gen., nov. sp. They expose some common features, such as the advanced type of first upper molar. possessing at least three complete rows of cusps. Because of this, and also of the upper premolar reduction, Boffius splendidus appears as the most specialized form within the Ptilodontoidea suborder.
    Several other characters of Hainina seem to be less advanced, such as the great number of upper premolars and the simple cusp-formula of the first lower molar.
    Till now, only H. godfriauxi has been recovered within the Thanetian fauna from Cemay-les-Reims, where it is very poorly documented.

Les mammifères de Rians (Eocène inférieur, Provence)
Marc Godinot Logo
Published online: 01/02/1981

Keywords: Eocene; Mammals; Provence; Rians

https://doi.org/10.18563/pv.10.2.43-126

  Abstract

    The fossil mammals discovered in the quarry of Rians (Sparnacian, Provence) are described. Among these forms, Hyracotherium is interesting because of the little molarization of the lower premolars and its small size, and Diacodexis by its small size and very primitive astragalus ; they may be the most primitive representatives of their respective orders. Also, Proviverra eisenmanni n. sp. is the smallest and most primitive hyaenodontid yet described. Hyopsodus itinerans is the first species of this genus described France. Among other rare fossils is a new species of bat, a small palaeoryctid, and other forms not yet identified. Marsupials are varied. Several new species are present among the rodents. The fauna is well-balanced and rich in small hyopsodontid condylarths. It is stratigraphically situated at the
    Dormaal reference-level, at the base of the early Eocene, and is considered equivalent to the late Clarkforkian of North America. The hypothesis is presented that new forms appearing at the beginning of the Wasatchian in North America migrated, in fact, at that time from Europe.
