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

First record of the genus Megaderma Geoffroy (Microchiroptera: Megadermatidae) from Australia.Suzanne J. Hand
Published online: 14/06/1995 Keywords: Australia; Chiroptera; Megaderma; Megadermatidae; Pliocene; Rackham's Roost Site; Riversleigh Abstract A new Tertiary megadermatid is described from Rackham's Roost Site, a Pliocene limestone cave deposit on Riversleigh Station, northwestern Queensland, Australia. It appears to represent the first Australian record of Megaderma GEOFFROY, 1810, a genus otherwise known from Tertiary African and European taxa and the living Asian species M. spasma (LINNAEUS, 1758) and M. (Lyroderma) lyra PETERS, 1872. Megademza richardsi n. sp. is one of the smallest megademiatids known. It exhibits a mixture of plesiomorphic and autapomorphic features, the latter appearing to exclude it from being ancestral to any living megadermatid. The new species is one of eight megadermatids identified from the Australian fossil record, most of which are referable to Macroderma MILLER, 1906.

On the genus Dikkomys (Geomyoidea, Mammalia)Morton Green and Philip R. BjorkPublished online: 01/10/1980Keywords: Dikkomys; Geomyoidae; North America https://doi.org/10.18563/pv.9.ext.343-353 Abstract 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. PV article infos Published in Vol. 9, Ext (1980) |

Nouvelles faunes de rongeurs de la fin Miocène inférieur en Provence. Implications géologiques et Paléogéographiques.Dominique LalaïPublished online: 01/09/1986Keywords: Biogeographic province; Biozonation; Correlation; Miocene; Palaeogeography; Rodentia Abstract 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. PV article infos Published in Vol. 16, Fasc. 2 (1986) |

Contributions à l'étude des micromammifères du gisement Miocène supérieur de Montredon (Hérault). 1- Le gisementJean-Pierre Aguilar and Jean-Yves CrochetPublished online: 30/06/1982Keywords: 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". PV article infos Published in Vol. 12, Fasc. 3 (1982) |

Les Ischyrictis de la transition Vindobonien-VallésienMiquel Crusafont i PairóPublished online: 15/09/1972Keywords: Ischyrictis; Mustelidae https://doi.org/10.18563/pv.5.5.253-260 Abstract Le groupe des Mustélides « Ischyrictoïdes » développe des tendances évolutives qu’engendrent des formes de Carnassiers prédateurs robustes et de grande taille. C’est une évolution comparable à celle que l’on trouve chez Plesiogulo, qui, lui, a une origine énigmatique (Petter, 1963). Chez les Mustélides on peut signaler deux lignées assez nettes : celle du sous-genre nominal des Laphyctis, plus conservatrice, plus mustéliforme, renfermant les espèces Ischyrictis (Laphyctis) mustelinus VIRET et L. zibethoides BLAINVILLE ; celle de type félinoïde caractérisée par L. Ginsburg (1961) avec la forme type Ischyrictis (Hoplicitis) florancei du Vindobonien inférieur de Pontlevoy-Thenay et I. helbingi VIRET, 1951 du Vindobonien supérieur de la Grive Saint-Alban. De plus rappelons que I. vorax DEHM et I. comitans DEHM du Burdigalien de Wintershof-West sont sans rapport avec les espèces du Miocène supérieur (Ginsburg, o.c.).

Premier signalement du Monachinae (Phocidae, Mammalia) dans le Sahélien (Miocène supérieur) d'Oran (Algérie)Christian de Muizon
Published online: 15/10/1981 Keywords: Algeria; Late Miocene; Phocidae https://doi.org/10.18563/pv.11.5.181-194 Abstract Messiphoca mauretanica nov. gen., nov. sp. représente le premier Phocidae fossile recensé en Afrique du Nord. Provenant du gisement sahélien (Miocène supérieur) de Raz-el-Aïn (Algérie), il est connu par quelques os du membre antérieur (humérus, radius, ulna), quelques vertèbres dorsales et un crâne très fragmentaire. La description de cette forme nouvelle amène à considérer Messiphoca mauretanica comme un Monachinae archaïque proche de l'origine du groupe Pliophoca - Monachus. L'incidence de cette interprétation d'un Phocidae «pré-Messinien ›› sur la crise de salinité du Messinien est aussi envisagée. PV article infos Published in Vol. 11, Fasc. 5 (1981) |

The microfauna of the Djebel Qafze CaveG. HaasPublished online: 15/09/1972Keywords: 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. PV article infos Published in Vol. 05, Fasc. 5 (1972) |

Rates of evolution in divergent species lineages as a test of character displacement in the fossil record : tooth size in Paleocene Plesiadapis (Mammalia, Proprimates)Phillip D. Gingerich
Published online: 16/12/1996 Keywords: character displacement; character divergence; fractal time series; Plesiadapis; Rates of evolution Abstract Two species lineages of North American late Paleocene Plesiadapis exhibit a pattern of size divergence from a common ancestral lineage. Time series of fossils in each of these lineages are analyzed to test the idea that size divergence represents competitive character displacement. The critical factor in a test of character divergence is showing that divergent lineages evolved directionally rather than randomly (multifactorially). Analysis of evolutionary rates and their temporal scaling in Plesiadapis shows that both divergent species lineages have the scaling slope expected for lineages evolving randomly rather than directionally, and size divergence in Plesíadapis does not represent character displacement. Rates of evolution commonly observed on a per-generation time scale are high enough to produce character displacement within a few generations. Thus character displacement is not likely to be visible on scales of time that can be studied in the fossil record. PV article infos Published in Vol. 25, Fasc. 2-4 (1996) |

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) |
