Rongeurs du Miocène supérieur de Chorora (Ethiopie): Cricetidae, Rhizomyidae,Phiomyidae, Thryonomyidae,Sciuridae.Denis Geraads
Published online: 15/12/1998 Keywords: cricetids; Ethiopia; phiomyids; rhizomyids; Rodentia; sciurids; thryonomyids; Upper Miocene Abstract Besides Dendromurids and Murids, the Chorora Rodents include 7 taxa, two of which are new. Afaromys nov. gen. is a Cricetodontine with very complicated lower molars, certainly isolated for a long time from Eurasian species. A Paraphiomys, with tetralophodont upper molars, is also quite different from other East African species, and its roots should probably he searched in the middle Miocene. Other taxa are less original, and more similar to the South Asiatic ones. PV article infos Published in Vol. 27, Fasc. 3-4 (1998) |

Decouverte d'un nouveau Diacodexis (Artiocactyla, Mammalia) dans l'Eocène inférieur de Silveirinha, Portugal.Carmen Estravis and Donald E. RussellPublished online: 15/09/1989Keywords: Artiodactyla; Eocene; Migration; Portugal; Silveirinha Abstract A new artiodactyl, Diacodexis antunesi n.sp., is described from the early Eocene of Silveirinha, Portugal. Comparisons are made with Diacodexis gazini GODINOT, 1978, D. varleti SUDRE et al., 1983, D. cf. varleti from Paris Basin sites, D. sp. from Dormaal and from localities in Spain and England, D. secans from North America and D. pakistanensis from Asia; affinities and evolutive tendencies are discussed. The presence of Diacodexis in the locality of Silveirinha confirms the very early Eocene age of the latter. As Diacodexis antunesi appears ta be more primitive than D. gazini from Rians (early Eocene of France), it lends corroboration to the interpretation (essentially based previously on condylarths) of the Silveirinha assemblage as the oldest Eocene fauna known in Europe and supports the hypothesis that early artiodactyls migrated from Europe to North America.

Revision der Equoidea aus den Eozänen Braunkohlen des Geiseltales bel Halle (DDR).Jens L. Franzen and Hartmut HauboldPublished online: 15/04/1986Keywords: Eocene; Europe; Mammalia; Perissodactyla; Stratigraphy; taxonomy Abstract The dentitions as well as one complete and several partial skeletons of Equoids from the Eocene lignite beds of the Geiseltal locality are revised. Instead of 13 species distinguished up to now 3 chronoclines with 5 species and 3 separate species are recognized (text. fig. 1). Propalaeotherium hassiacum HAUPT, 1925 is evolving into Propalaeotherium isselanum (CUVIER, 1824) between the levels of the « obere Unterkohle ›› and the « untere Mittelkohle ›› of the Geiseltal section. Propalaeotherium argentonicum GERVAIS, 1849 is shown to be present in the « untere Unterkohle ››, whereas Lophiotherium pygmaeum (DEPERET,1901) occurs in the « obere Mittelkohle ›› and in the « oberes Hauptmittel ››. Plagiolophus cartieri STEHLIN, 1904 appears during the transition from the « Mittelkohle ›› into the « Oberkohle ›› as the earliest true Palaeothere. Therefore the « Oberkohle ›› is already regarded as Upper Eocene. This is corroborated by the occurrence of a phyletic descendant of Propalaeatherium parvulum (Propalaeotherium n.sp.) in the middle and upper "Oberkohle " because this species appears otherwise for the first time at the mammal level of Lissieu. On the other hand Propachynolophus gaudryz (LEMOINE, 1878) described by Matthes (1977) from the « untere Unterkohle ›› turns out te be in fact a Phenacodont. Thus the decisive argument for classifying the « untere Unterkohle ›› as Lower Eocene has to be dropped. Biostratigraphically the « Unterkohle ›› and the «Basishauptrnittel ›› correspond with the lower Middle Eocene (mammal level of Messel), whereas the «unteres Hauptmittel ›› and the « untere Mittelkohle ›› are equivalent to the middle part of the middle Eocene (mammal level of lssel), and the « obere Mittelkohle ›› together with the « oberes Hauptmittel ›› coincide with the upper Middle Eocene (mammal level of Bouxwiller).

Types dentaires adaptatifs chez les sélaciens actuels et post-paléozoïques.Henri Cappetta
Published online: 01/09/1986 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. PV article infos Published in Vol. 16, Fasc. 2 (1986) |

Analysis of mammalian communities from the late Eocene and Oligocene of southern FranceSerge Legendre
Published online: 15/12/1986 Keywords: Late Eocene; Mammalian communities; Oligocene; Quercy; Southern France Abstract Valverde's cenogram method is used to analyse mammalian communities from the late Eocene to late Oligocene of southern France, mainly from the "Phosphorites du Quercy". Cenogram analysis involves plotting the size of each component species in a fauna on a semilog diagram in rank order, permitting fossil faunas to be compared with Recent ones. The configurations of Recent communities serve as models for establishing the general environmental characteristics of fossil mammalian faunas. This method of analysis applied to faunal sequence can reveal major and sudden ecological perturbations. The paleobiogeographical event (i.e. the mammalian immigration wave) at the Eocene-Oligocene Boundary in western Europe, known as the «Grande Coupure", is here shown to represent a drastic and sudden ecological change: late Eocene tropical environments in Europe deteriorated rapidly turning to subdesert or desert environments al the beginning of the Oligoccne.

Die Referenzfauna des Geiseltalium, MP levels 11 bis 13 (Mitteleozan, Lutetium)Hartmut HauboldPublished online: 04/12/1989Keywords: Eocene; Geiseltal; Land mammal ages; Mammalian reference levels Abstract The Middle Eocene Fossillägerstätte of the Geiseltal lignite beds near Halle/S. (German Democratic Republic) is the reference locality of the European land mammal age Geiseltalian and of the Mammalian Paleogene reference levels MP 11 - MP 13. Due to this importance a reinvestigation is given of the lithostratigraphical development of the Geiseltal beds and of their vertebrate sites. The last are genetically related to the southwest border of the Geiseltal depression and the influx of carbonate-rich waters. The geographical distribution and stratigraphical position of the fossiliferous sites depends on subrosive and tectonically controlled distribution of coal seams. The geological factors and the known stratigraphical guide of some mammalian species suggest corrections of the age of some sites. Four of the alltogether five coal bearing phases contain the 35 sites with mammalian remains. By the distribution of the around 69 mammal species are characterized, with 5 faunal steps ranging from MP 11 to MP 14 or over the Geiseltalian up to the Lower Robiacian. Well distant are the faunas of MP 11 and MP 12. Beginning with MP 12 up to MP 13/14, the fossil record is very frequent by 27 sites. This evidence coincides somewhat more with the concept of land mammal ages compared to that of the punctual mammalian reference levels. PV article infos Published in Vol. 19, Fasc. 3 (1989) |

Sur les Condylarthres Cernaysiens Tricuspiodon et Landenodon (Paléocène supérieur de France)Donald E. RussellPublished online: 01/10/1980Keywords: Arctocyonidae; Condylarths; Late Paleocene; Tricuspiodontidae https://doi.org/10.18563/pv.9.ext.127-166 Abstract The numerical importance of the Condylarths in the Cernaysian fauna is discussed. The Condylarth family, Tricuspiodontidae, is reviewed in the light of new material and its close relationships to the Phenacodontidae is suggested ; one new species is recognized : Tricuspiodon sobrinus. European Arctocyonidae are reviewed and the recentclassification of Van Valen is briefly commented on. Also, the arctocyonine Landenodon is described for the first time in Thanetian (Late Paleocene) sediments ; two new species are proposed : T. lavocati and T. phelizoni.

Les Dipodidae (Mammalia, Rodentia) d'Europe occidentale au Paléogène et au Néogène inférieur: origine et évolution.Marguerite Hugueney and Monique Vianey-Liaud
Published online: 01/10/1980 Keywords: Dipodidae; Late Oligocene; Quercy Phosphorites https://doi.org/10.18563/pv.9.ext.302-342 Abstract 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. PV article infos Published in Vol. 9, Ext (1980) |

Cricetid rodents from Siwalik deposits near Chinji village. Part I: Megacricetodontinae, Myocricetodontinae and Dendromurinae.Everett H. Lindsay
Published online: 15/10/1988 Keywords: Dendromurinae; Megacricetodontinae; Middle Miocene; Myocricetodontinae; Rodents; Siwalik Abstract Seventeen species of cricetid rodent are recognized and described from lower and middle Siwalik deposits in the Potwar Plateau of Pakistan. These species are grouped in three categories, characterized as subfamilies (e. g., Megacricetodontinae, Myocricetodontinae, and Dendromurinae); an additional and more abundant category of rodents from these deposits, the Democricetodontinae, is excluded from this study, and will be described in a later study. Fifteen of the species are new, and four new genera are described. The Siwalik cricetid taxa are : Megacricetodon aquilari, n. sp.; Megacricetodon sivalensis, n. sp.; Megacricetodon daamsi, n. sp.; Megacricetodon mythikos, n. sp.; Punjabemys downsi, n. gen. & n. sp.; Punjabemys leptos, n. gen. & n. sp.; Punjabemys mikros, n. gen. & n. sp.; Myocricetodon sivalensis, n. sp.; Myocricetodon sp.; Dakkamyoides lavocati, n. gen. & n. sp.; Dakkamyoides perplexus, n. gen. & n. sp.; Dakkamys asiaticus, n. sp.; Dakkamys barryi, n. sp.; Dakkamys sp.; Paradakkamys chinjiensis, n. gen. & n. sp.; Potwarmus primitivus, n. gen.; and Potwarmus minimus, n. gen. & n. sp. This diverse record of middle Miocene small mammals illuminates a profound radiation of cricetid rodents in southem Asia, the effects of which were felt in Europe and Africa as well as the rest of Asia.

Rongeurs (Mammalia, Rodentia) du Miocène de Beni-MellalJean-Jacques Jaeger
Published online: 15/02/1977 Keywords: Morocco; Neogene https://doi.org/10.18563/pv.7.4.91-125 Abstract 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. PV article infos Published in Vol. 07, Fasc. 4 (1977) |

La poche à phosphate de Ste-Néboule (Lot) et sa faune de vertebres du Ludien supérieur. 12- Fissipèdes (Carnivores)Louis de Bonis

Celle-ci se distingue suffisamment des espèces déjà décrites pour constituer un taxon particulier : Cynodictis lacustris neboulensis n. s. sp. . L'étude des variations à l'intérieur de cette population nous a conduit à reconsidérer les critères utilisés pour définir les espèces existantes et à regrouper certaines d'entre elles. Il semble qu'il demeure cependant trois lignées distinctes dans le genre Cynodictis mais le matériel nous paraît encore insuffisant pour traduire cette remarque en termes de systématique.

Study of the Turolian hipparions of the lower Axios valley (Macedonia, Greece). 4. Localities of Dytiko.George D. KoufosPublished online: 15/12/1988Keywords: Equidae; Greece; Hipparion; Lower Axios Valley; Macedonia; Mammalia; Turolian Abstract The hipparions from the Dytiko localities of the lower Axios valley (Macedonia, Greece) are studied. The material comes from three localities Dytiko-l, 2, 3 (DTK, DIT, DKO), which are situated near the village of Dytiko, about 60 km northwest to Thessaloniki. Three species have been determined, the medium-sized H. mediterraneum, the small-sized H. matthewi and the very small-sized H. periafricanum. The determined Hipparion species, their morphological characters and their comparison with the other Axios valley material indicate a Late Turolian age for the Dytiko localities.
