Rongeurs du Miocène supérieur de Chorora, Ethiopie: Murinae, Dendromurinae et conclusions.Denis GeraadsKeywords: Ethiopia; Late Miocene; Muridae; RodentiaAbstract The subfamilies Murinae and "Dendromurinae" both include 4 species at Chorora. Among the former, while Preacomys nov. gen. seems to be a forerunner of Acomys, the affinities of the remaining, poorly known taxa, are more difficult to evaluate. The bulk of the fauna, remarkably, consists of Dendromurines. Their similarities with those of Ngorora tends to pull the site back in time, but the large size and diversity of Murines fit better an age more recent than the very beginning of the Late Miocene.

Mode de vie et affinités de Paschatherium (Condylarthra, Hyopsopontidae) d'après ses os du tarseMarc Godinot, Thierry Smith and Richard SmithKeywords: Astragalus; Calcaneum; Condylarthra; Eocene; Functional morphology; Paschatherium; PHYLOGENYAbstract 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.

Un Haplobunodontidae nouveau Hallebune krumbegeli nov.gen. nov.sp. (Artiodactyla, Mammalia) dans l'Eocène moyen du Geiseltal près Halle (Sachsen-Anhalt, Allemagne)Jorg Erfurt and Jean SudreKeywords: Artiodactyla; Geiseltal; Germany; Mammal; Middle Eocene; new gen.; new sp.Abstract A new genus and species of haplobunodontid artiodactyl, Hallebune krumbiegeli nov. gen. nov. sp., is described from the middle Eocene Geiseltal Fauna (Saxon-Anhalt, Germany). Its stratigraphic range is restricted to the MP 13 ("obere Mittelkohle") of the Geiseltalian. The material consists of seven fragments, representing both upper and lower jaws. It is indicated, that H. krumbiegeli was a small bunodont herbivore. The size and primitive character of the teeth suggest that the genus possibly is directly derived from Diacodexeidae.The new material forms the basis for reinterpreting the haplobunodontid phylogeny.

Les Dipodidae (Mammalia, Rodentia) d'Europe occidentale au Paléogène et au Néogène inférieur: origine et évolution.Marguerite Hugueney and Monique Vianey-LiaudKeywords: Dipodidae; Late Oligocene; Quercy PhosphoritesAbstract The study of three new populations of Plesiosminthuspromyarion from the "phosphorites du Quercy" and of material from "Auvergne" brings new data on european oligocene Dipodidae. They appear in Western Europe at the beginning of late Oligocene. Evolutionary trends of the group are drawn and particularly the emergence of morphotypes announcing P. schaubi, from the Coderet level, is revealed among the most recent populations of P. promyarion. Differences are attempted to be drawn between the three species : P. promyarion, P. myarion and P. schaubi by restudying the type-population of P. myarion from the aquitanian deposits of Chavroches (Allier) in comparison with two other populations from the same age and the same region. Relationships between early european, american and asiatic Dipodidae are discussed. Article infos Published in Vol. 9, Ext (1980) |

A mandible of the hyracoid mammal Titanohyrax andrewsi in the collections of the Muséum National d'Histoire Naturelle, Paris (France) with a reassessment of the speciesRodolphe TabuceKeywords: Afro-Arabia; Fayum; Oligocene; Titanohyracidaedoi: 10.18563/pv.40.1.e4 Abstract An unpublished mandible of the large hyracoid Titanohyrax andrewsi from the early Oligocene Jebel Qatrani Formation, Fayum Depression, Egypt is described. This specimen has a twofold importance. Firstly, it opens an unexpected window on early paleontological research in the Fayum because it was discovered as early as 1904 by the French paleontologist René Fourtau during an expedition to the Fayum organized by the Muséum National d’Histoire Naturelle, Paris (MNHN). This expedition has remarkably never been mentioned in the literature. Secondly, the mandible documents the best-preserved specimen of T. andrewsi, permitting a revision of one of the very rare Paleogene hyracoids. Interestingly, the new mandible was discovered two years before the first report of the species by Charles W. Andrews. The hypodigm of T. andrewsi is reviewed and the dentition as a whole is compared in detail, notably with other Titanohyrax species from the Fayum. The validity of the large Titanohyrax “schlosseri” species is discussed, but a pronounced sexual size dimorphism for T. andrewsi is favoured. Article infos Published in Vol.40-1 (2016) |

Eggshell microstructure and porosity of the Nicobar scrubfowl (Megapodius Nicobariensis, great Nicobar island, India)Géraldine Garcia, Ashu Khosla, Ashok Sahni and Monique Vianey-LiaudKeywords: conductance porosity; eggshell microstructure; incubation conditions; Megapodesdoi: 10.18563/pv.36.1-4.75-88 Abstract The eggshell of Nicobar scrubfowl (Megapodius nicobariensis) is described for the first time. Its egg porosity is calculated and discussed with data from several taxa (another megapode, some extant and fossil reptiles including a titanosaur group) in order to compare incubation types with eggshell structure. Eggshell microstructure reflects first phylogenetic traits and does not seem to have developed major adaptative features due to the incubation conditions, except for the pore canals.

The Ctenodactylidae (Rodentia) from the Oligocene of Ulantatal (inner Mongolia, China)Monique Vianey-Liaud, Norbert Schmidt-Kittler and Laurent MarivauxKeywords: Adaptive radiation; Ctenodactylidae; Mongolia; Oligocene; RodentsAbstract This paper proposes a systematic revision of the Oligocene Mongolian Ctenodactylidae, on the basis of abundant material obtained by screen/washing operations in stratified localities of the Ulantatal area (Inner Mongolia) (UTL1, 2, 3, 4, 5, 7, 6 & 8). A Chinese-German team has collected several thousands of isolated rodent teeth, and a number of fragmentary jaws. A new genus is identified (Alashania nov. gen. tengkoliensis nov. sp.), and eight former species are reevaluated, Karakoromys decessus, Tataromys sigmodon, T. minor, T. plicidens, Yindirtemys ulantatalensis, Y. bohlini, Y. deflexus, with several synonymies. A new Yindirtemys species is described: Y. shevyrevae nov. sp. and another one close to that: Y. aff. shevyrevae nov. sp. Four new species, which are rare in the localities, remain in open nomenclature because they are not well-represented. Yindirtemys differs from the other genera by the permanence of crescentic structures, while the other genera show a general reduction of the trigonoid area (= anterior valley). We define a range of size variation for each well documented population. Although the dental morphology shows a wide range of variation, given that transitional morphologies occur in a single locality, it is possible to provide a clear definition for most species. We show that dental patterns of the different genera can be derived from the pattern of Karakoromys. As a number of Tataromyinae have been determined in several localities from China, Kazakhstan and Mongolia, usually on the basis of scarce material, or surface collections, the present study would be used to re-evaluate their attribution inasmuch as the taxa are now placed in the Oligocene stratigraphy. The diversity of sizes and forms reflects the adaptive radiation of the family during the Oligocene, within a forested environment where the vegetation was probably abundant.

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

Rongeurs Miocènes dans le Valles-Penedes 2 : Les rongeurs de Castell de BarberaJean-Pierre Aguilar, Jordi Agusti and J. GibertKeywords: Castell de Barbera; Miocene; Rodents; Valles-PenedesAbstract The rodent-fauna (Cricetidae and Gliridae) recently found at Castell de Barbera (Spain) is similar to those from the other locslities of the Valles - Penedes - Can Ponsic 1 and Can Llobateres - : same composition and similar evolutionary level of the different species. On the other hand this fauna is different from those of Upper Vindobonian and Vallesian localities of the Calatayud - Teruel area. Castell de Barbera has an intermediate chronological position between the localities of Anwil (Switzerland) and Can Ponsic 1. It is still not possible to validate or invalidate the initial attribution based on absence of Hipparion of Castell de Barbera to the Upper Vindobonian.

The fossil rabbit from Valdemino cave (Borgio Verezzi,Savona) in the context of western Europe Oryctolagini of Quaternary.Giulia Nocchi and Benedetto SalaKeywords: Lagomorpha; Mammals; North-western Italy; Oryctolagus; Plio-Pleistocene; SavonaAbstract The present research deals with the remains of a lagomorph found at Valdemino cave and comes to the conclusion that it is a rabbit with peculiar characteristics in comparison with the other known species Oryctolagus laynensis, O. lacosti and 0. cuniculus. We studied other fossil remains of rabbit populations from Villafranchían and middle Pleistocene deposits and compared them with data from the literature and with recent material. The analysis leads us to maintain two phylogenetic hypotheses about the history of Oryctolagini. The ñrst one, already formulated by Lopez Martinez, suggests that 0. cuniculus derives from O. laynensis,while the origin of O. lacostí is unknown; according to the second hypothesis 0. laynensis would be the common ancestor of two phyletic lineages, 0. lacosti and 0. cuniculus. In both cases the lagomorph from Valdemino would be the form derived from 0. lacosti, from which however it differs in peculiar characteristics. Since the rabbit from Valdemino survives until the beginning of Postgalerian, its disappearance may coincide with the retreat of 0. cuniculus from western Europe in Spain and, perhaps, in south-western France, before the last glaciation. O. cuniculus survived in Spain, from where it spread once again over western Europe as a result of man. Article infos Published in Vol. 26, Fasc. 1-4 (1997) |

Contributions à l'étude du gisement Miocène supérieur de Montredon (Hérault). Les grands mammifères. 3 - Les artiodactyles ruminantsLéonard Ginsburg and Herbert ThomasKeywords: Artiodactyla; France; Montredon; Ruminentia; Upper MioceneAbstract The remains of Ruminantia are very rare at Montredon. No specific determination was possible. We have only one Micromeryx, one small cervid, one tragocere and one (?) gazella. The faunal spectrum is in good correlation with the general retreat of the cervids in the European upper Miocene, but in contrast it is not convenient for the bovids, which are in expansion at the same time. For them, we have to invoke the local ecological conditions. Article infos Published in Vol. 18, Ext (1988) |

Arvicolinae (Rodentia) du Pliocène terminal et du quaternaire ancien de France et d'Espagne.Jacques MichauxKeywords: Arvicolinae; France; Pleistocene; Pliocene; Spaindoi: 10.18563/pv.4.5.137-214 Abstract Two steps can be distinguished in the history of the first invasion of western and south western Europe by the arvicolines. The first step corresponds to the installation of these rodents with the immigration of Promimonys inxuliferus Kowalski, then of Mimomys stehlini Kormos and of Mimomys gracilis (Kretzoi). The second is characterized by the establishment of a geographic differentiation in the arvicoline fauna between the south of France and Spain, from where are described new species of Mimomys (Mimamys cappettai, Mimomys septimanus, Mimonys medasensis), and the rest of France, where are found only elements already known from central Europe or England (Mimomys polonicus Kowalski, Mimomys pliocaenicus F. Major, Mimomys reidi Hinton, or forms very close to the latter). This geographic differentiation, which is very certainly the consequence of the division of Europe into distinct climatic provinces, one of them being the southern province comprising at least Spain and southern France, could result from a cladogenetic evolution of Mimomys stehlini and Mimomys gracilis after their immigration. The present work is also a contribution to the search for correlations between the diverse micromammal localities of the latest Pliocene (or early Villafranchian) and of the early Quaternary of Europe.

Les sélaciens du Miocène de la région de MontpellierHenri CappettaKeywords: Ichtyofauna; Miocene; Montpellierdoi: 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.
