Nouvelles faunes de rongeurs de la fin Miocène inférieur en Provence. Implications géologiques et Paléogéographiques.Dominique LalaïKeywords: Biogeographic province; Biozonation; Correlation; Miocene; Palaeogeography; RodentiaAbstract Rodents from the new localities of Châteauredon (Alpes-de-Haute-Provence) and La Denise (Bouches-du-Rhône) show more similarities with the rodents known from the Czecho-Slovak locality of Franzenbad than with the species found in contemporaneous Lower Miocene faunas located westward of the present Rhône Valley. This is another data wich support the existance of several biogeographical provinces in Southern France during Lower Miocene. The correlations which have been settled down allow new datations of several formations in Provence and give new information on the Aquitanian and Burdigalian paleogeographies of this region. More precise stratigraphical allocations are given to some other localities of Central Europe. Article infos Published in Vol. 16, Fasc. 2 (1986) |

On the genus Dikkomys (Geomyoidea, Mammalia)Morton Green and Philip R. BjorkKeywords: Dikkomys; Geomyoidae; North AmericaAbstract The geomyoid genus Dikkomys is well represented in a sample from the Black Bear Quarry Il local fauna of Early Hemingfordian age in Bennett County, South Dakota. Isolated unworn P/4's of Dikkomys matthewi WOOD have a prominent median cristid (sagicristid) with a connection to the metaconid and the hypolophid. With wear, P/4 does not become as molariform as P/4 because of this cristid. Article infos Published in Vol. 9, Ext (1980) |

Multituberculate endocranial castsZofia Kielan-JaworowskaKeywords: Allotheria; Cretaceous; endocranial cast; Mongolia; multituberculatesAbstract 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. Article infos Published in Vol. 13, Fasc. 1-2 (1983) |

Sur la présence de dents de mammifères (Creodonta, Perissodactyla) près de la limite Paléocène-Eocène à Hoegaarden, BelgiqueRichard Smith and Jerry J. HookerKeywords: Belgium; Creodonta; Landenian; Mammals; PerissodactylaAbstract Amongst a collection of selachian teeth made at Hoegaarden in a marine level of Bruxellian (Lutetian) age, containing a reworked Landenian (Sparnacian) fauna mixed with a contemporaneous one, a few teeth of terrestrial mammals have been discovered. They comprise two rare European taxa: ? Hallensia sp. and Palaeonictis gigantea, both known from the Landenian. Even though the ?Hallensia has not been definitely identified, il differs from the only perissodactyl of this age previously recorded from Belgium (Cymbalophus cuniculus).

Carolocoutoia ferigoloi nov. and sp. (Protodidelphidae), a new Paleocene "opossum-like" marsupial from Brazil.Francisco J. Goin, Edison V. Oliveira and Adriana M. CandelaKeywords: Brazil; Didelphimorphia; Itaborai; Marsupialia; New taxa; Paleocene; Protodidelphidae; South AmericaAbstract Carolocoutoia ferigoloi gen. et sp. nov. is the largest of protodidelphid marsupials, known from Middle Paleocene levels at Itaboraí Formation, southeastern Brazil. It differs from other members of this family in having molars with low cusps which are basally inflated, rounded crests without cutting edges, and a thick enamel layer which is wrinkled, specially at the labial half. A comparative analysis among representatives of this family led us to recognize only three genera undoubtely assignable to it: Protodidelphis PAULA COUTO, 1952, Robertbutleria MARSHALL, 1987, and Carolocoutoia gen. nov. Protodidelphids lack the basic derived features diagnostic of Polydolopimorphian marsupials, while most of its derived features agree with its belonging to the Didelphimorphia. Protodidelphids comprise a specialized clade of opossum-like marsupials adapted to frugivorous or frugivore-omnivorous feeding habits. They differ from other didelphimorphians in having very large, spire-like entoconids, reduced and antero-posteriorly compressed paraconids, absence of stylar cusp C and of para- and metaconules, large stylar cusps B and D which are proximate to each other, short postmetacristae, eccentric protocones, and molars that increase rapidly in size from M/ml to M/m3.

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.

Additions of the Geiseltal mammalian faunas, Middle Eocene: Didelphidae, Nyctitheriidae, Myrmecophagidae.Gerhard Storch and Hartmut HauboldKeywords: Edentata; Geiseltalian; German Democratic Republic; Lipotyphla; Marsupialia; MP 11-13Abstract 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. Article infos Published in Vol. 19, Fasc. 3 (1989) |

La région des phosphorites du QuercyA. CavailléKeywords: Quercy PhosphoritesAbstract L'exploitation des phosphates s'est produite surtout de 1890 à 1914 de Saint-Antonin à Cajarc, sur le Causse de Limogne, dont l'histoire géologique et morphologique peut expliquer les conditions de gisement du minerai, et aussi la découverte des nombreux, variés et beaux fossiles qu'on a extrait des poches en même temps que la phosphorite. Le Causse de Limogne est le nom donné par les géographes au plateau calcaire, faisant partie des Causses du Quercy, et compris entre la vallée du Lot au Nord et celle de "Aveyron au Sud". En fait, le nom de "causse" désigne localement un terroir, un paysage, à sous-sol de calcaire, à sol peu épais, qui s'oppose aux sols argileux des « terreforts » et aux sols légers et profonds des "boulbènes". Chaque communauté agricole distinguait ainsi son causse, par exemple le causse de Caylus, le causse de Limogne ou le causse de Cajarc. C'est par extension que l'appellation Causse de Limogne désigne tout un petit pays. La présence des poches à phosphate déborde un peu vers le Nord la vallée du Lot, et vers l'Est le Causse de Limogne proprement dit (Causse de Villeneuve).

The skull of Arsinoitherium (Mammalia, Embrithopoda) and the higher order interrelationships of ungulatesNicholas CourtKeywords: Arsinoitherium; PHYLOGENY; Skull; UngulateAbstract Detailed anatomical description of arsinoithere cranial remains from the Lower Oligocene, Fayum Depression, Egypt, provides the basic data for a systematic investigation. All cranial and some postcranial features are assessed from a phylogenetic standpoint. Several soft tissue characters are then added to a cladistic analysis based on 54 derived ungulate morphological characters. The resulting phylogenetic hypothesis implies that perissodactyls, sirenians, proboscideans and arsinoitheres constitute a monophyletic unit (5 synapomorphies). However, increasing the tree length by 3 steps reveals a closer association between hyraxes and perissodactyls. Nevertheless, 13 synapomorphies link proboscideans, sirenians and arsinoitheres to the exclusion of all other ungulates. Form of the sphenopalatine and ethmoid foramina, recurved posttympanic process, absence of a fenestra rotundum in the petrosal, vestigial paroccipital process of the exoccipital and the highly unusual absence of a hypoglossal foramen in the skull, imply a robust sister-group relationship between arsinoitheres and proboscideans. In this analysis artiodactyls share only one derived character with all other ungulates studied. Monophyly of Ungulata, including Artiodactyla, is therefore only weakly supported. It is argued that pedal anatomy of hyraxes is non-homologous with that of Tethytheria. Arsinoitherium should now be classified within Tethytheria, sharing a sister-group relationship with Proboscidea. Hyraxes are excluded, thus refuting the concept of Paenungulata. However, monophyly of the wider concept, Pantomesaxonia, containing hyraxes, perissodactyls, sirenians, proboscideans and now, arsinoitheres, is supported by this study.

Reflections on some Russian eotheriodonts (Reptilia, Synapsida, Therapsida)Denise Sigogneau-Russell and P. K. TchudinovKeywords: Reptilia; Russia; Synapsida; Therapsidadoi: 10.18563/pv.5.3.79-109 Abstract As a result of the enrichment of eotheriodont material by one of us (P.K.T.), these specimens (essentially Biarmosuchur and Eotitanosuchur) are reexamined and refigured. A reevaluation of their particularities supports the distinction of two families, for which new diagnoses are proposed. This leads us to discuss the affinities of these families, with respect to the sphenacodonts on one hand, and to the South African primitive theriodonts on the other (gorgonopsids and ictidorhinids). This study contains inherent paleogeographic consequences which are considered in conclusion. Article infos Published in Vol. 05, Fasc. 3 (1972) |

Rongeurs caviomorphes de l'Oligocène de Bolivie. 1 Introduction au deseadien de BolivieRobert HoffstetterKeywords: Rodentia; South AmericaAbstract The Tertiary of the Salla-Luribay basin consists of red beds affected by the second period of the andine compression, of Miocene ending age. The Tertiary layers are exposed at an approximate elevation of 3.500 to 4.000 meters. Two stratigraphic units can be distinguished in them: the Luribay conglomerates, in which vertical clifts result from erosion, and the Salla layers consisting mostly of consolidated clays. These clays are very fossiliferous and have furnished a rich vertebrate fauna which gave to R. Hoffstetter the possibility to establish the Oligocene age of these beds. Sediments of same age has been reported to be present in several other places of Bolivia, particularly near Lacayani, where have been collected highly hypsodont Rodents, different from those found in Salla-Luribay basin.

Rongeurs (Mammalia, Rodentia) du Miocène de Beni-MellalJean-Jacques JaegerKeywords: Morocco; NeogeneAbstract The rodent fauna of Beni-Mellal is characterized by the abundance of ctenodactylids and cricetids. The latter are represented by four distinct species, among which a new form. Dakkamys zaiani nov. gen., nov. sp. is described. A detailed morphological analysis shows that, contrary to that which had been established before, « Cricetodon ›› atlasi Lavocat, 1961, is not closely related to any European form known; this species is attributed, in consequence, to the new genus Mellalomys. A simple biometric analysis has shown that the genus Myocricetodon Lavocat, 1952, is represented in this locality by two distinct species. The systematic homogeneity of the Beni-Mellal cricetids is also demonstrated: they can, as a matter of fact, all be referred to the subfamily Myocricetodontinae. The definition of this subfamily is completed. The sciurids and glirids are also reviewed in the light of new systematic and biogeographic information established ln Europe. A new species of Atlantoxevus from the early Pleistocene of Morocco, A. huvelini nov. sp., is described. It is probably the descendant of A. tadlae from Beni-Mellal. Biogeographic analysis leads one to consider this fauna as the result of geographic isolation in the Maghreb since the late Oligocene or the early Miocene. In particular no direct European influence can be discerned. Stratigraphic considerations resulting from the discovery of new localities in North Africa lead to the confirmation of the ante-Vallesian age of this fauna and to its parallelism with the faunas of La Grive in Western Europe and Fort Ternan in East Africa. The peculiar geologic nature of this locality is discussed. Article infos Published in Vol. 07, Fasc. 4 (1977) |

Les Gliridés (Rodentia) de l'Oligocène supérieur de Saint-Victor-la-Coste (Gard).Marguerite HugueneyKeywords: Gliridae; Late Oligocenedoi: 10.18563/pv.2.1.1-16 Abstract The locality of St.-Victor-la-Coste (Gard) has yielded, rather abundantly, teeth of two glirids hitherto very poorly known: Glirudinus praemurinus (Freudenberg) and Glirudinus glirulus (DEHM). It has permitted, moreover, new views on the evolution of Peridyromys murinus (POMEL). Study of these forms confirms the late Oligocene age of the fauna, without allowing, however, further precision.
