Les Paramyidae (Rodentia) de l'Eocène inférieur du bassin de Paris.Jacques MichauxPublished online: 7/15/68Keywords: Ailuraviinae; Eocene; Paramyinae; Rodents https://doi.org/10.18563/pv.1.4.135-193 Abstract The exploitation of new early Eocene localities in the Paris Basin has resulted in the collecting of numerous mammalian remains, among which are about 300 isolated teeth representing the rodents. They belong, for the most part, to the paramyid group. Only the latest level of the early Eocene has yielded rodents belonging to the pseudosciurid group. The paramyids, the object of this study, are represented by at least 5 genera and 10 species; they are distributed among 4 clearly dilferentiated subfamilies : Paramyinae Simpson 1945, Pseudoparamyinae Michaux 1964, Ailuraviínae n. subf., Microparamyinae Wood1962.

La poche à phosphate de Ste-Néboule (Lot) et sa faune de vertebres du Ludien supérieur. 11- CréodontesBrigitte Lange-BadréPublished online: 9/25/78Keywords: Creodonta; Eocene; Quercy Phosphorites Abstract The teeth and the astragale of the Creodonta from Ste-Néboule (Lot) are referred to Hyaenodon brachyrhynchus. Isolated teeth fit morphologically the material from La Débruge (Middle Ludian). However, biometric analysis suggests an Upper Ludian age. PV article infos Published in Vol. 08, Fasc. 2-4 (1978) |

Un gisement à mammifères dans la formation lacustre d'âge Miocène moyen du Collet Redon près de St-Cannat (Bouches-du-Rhone). Implications stratigaphiquesJean-Pierre Aguilar and G. ClauzonPublished online: 4/10/79Keywords: France; Neogene; Rodentia Abstract The new fauna of Collet Redon (Bouches-du-Rhône, France) is dated by three rodents: Megacricetodon aff. bavaricus, Democricetodon affinis mutilus and Peridyromys cf. hamadryas. They correlate this locality with Oggenhof and Ohningen in Bavaria (Western Germany). As the radiometric age of Ohningen is estimated between 14 and 13 M.Y., these three localities are of Serravallian age. This datation brings a complete readjusment of the stratigraphy of the section of Collet Redon formerly described by Collot and Combaluzier. The marine deposits with underly the continental formation with the mammal fauna, are Burdigalian. The angular unconformity between the marine and the continental deposits gives evidence of an episode of emersion on the margin of a sedimentary basin, with deformation and erosion. Owing to the newly discovered fauna, this geodynamical event is clearly settled within the regional geographical and chronological context. Lacustrine and continental deposits of such an age were up to now unsuspected in this area. PV article infos Published in Vol. 08, Fasc. 5 (1979) |

La poche à phosphate de Ste-Néboule (Lot) et sa faune de vertebres du Ludien supérieur. 8- Insectivores et Chiroptères.Bernard SigéPublished online: 9/25/78Keywords: Eocene; Quercy Phosphorites 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. PV article infos Published in Vol. 08, Fasc. 2-4 (1978) |

La poche à phosphate de Ste-Néboule (Lot) et sa faune de vertébres du Ludien supérieur. 4- CrocodiliensEric Buffetaut
Published online: 9/25/78 Keywords: Eocene; Quercy Phosphorites Abstract Crocodilians are represented in the Upper Eocene of Sainte·Néboule (Lot) by an isolated parietal and a dorsal scute, bath from young individuals. They are refferred to Diplocynodon sp. Predators (mammals and birds) are probably responsible for the occurrence of remains of small crocodilians (belonging to the genera Allognathosuchus and Diplocynodon) in the phosphorltes of Quercy.

Essai de filiation des campagnols et des lemmings (Arvicolidae, Rodentia) en zone holartique d'après la morphologie dentaire.Jean ChalinePublished online: 10/1/80Keywords: Arvicolidae; Dental morphology; Paleogeography; phyletic relationships Abstract The Arvicolid evolution results in an increase of the dental structure complexity. The M3/ differenciation seems to characterise the tribe subdivisions, that of M/1 being variable from one to another lineage. The phyletic relationships of fossil lineages are discussed from a paleogeographic point of view. PV article infos Published in Vol. 9, Ext (1980) |

Functional aspects of the evolution of rodent molarsPercy M. ButlerPublished online: 10/1/80Keywords: Chewing; Muridae; Rodents; Wear facets Abstract The wear facets of primitive rodents can be homologized with those of primitive primates and ungulates. As in primates, the jaw movement was ectental, with an increased anterior component in the lingual phase (phase ll). The buccal phase (phase I) in rodents approaches the horizontal and it tends to be reduced in importance in comparison with the lingual phase. ln more advanced rodents the efficiency of grinding is increased by the development of additional cutting edges of enamel (e.g. enlargement of hypocone, development of mesoloph and lingual sinus). The buccal phase movement becomes lined up with the lingual phase movement to form a single oblique chewing stroke,resulting in planation of the crown. As the stroke becomes more longitudinal (propalinal) the enamel edges become more transverse. In Muridae propalinal chewing evolved before the loss of cusps, facets were reorientated and additional cusps developed. PV article infos Published in Vol. 9, Ext (1980) |

La morphologie dentaire des Thalattosuchia (Crocodylia, Mesosuchia).Patrick Vignaud
Published online: 12/15/97 Keywords: Dental morphology; Dental types; feeding habits.; Jurassic; Metriorhynchidae; Systematics; Teleosauridae; Thalattosuchia Abstract The tooth morphology of the Thalattosuchia (marine crocodilians from the Jurassic and the Early Cretaceous) is analysed. The Callovian from Poitou and the Kimmeridgian from Quercy have yielded many remains of Metriorhynchus, Steneosaurus and Machimosaurus. These remains allow us to study the variations of tooth morphology during ontogenic growth, tooth replacement and the location of the teeth. We have defined different tooth types for these genera. In Metriorhynchus, the two tooth types defined do not coincide with the two groups recognized in the Callovian (broad-skulled and narrow-skulled metriorhynchids) but reflect the prey preferences of these forms. In Steneosaurus and Machimosaurus the five tooth types deñned are in agreement with the main taxa known from the Bathonian to the Early Cretaceous. This study allows to precise the function and the prey preference of the Thalattosuchia during the Jurassic and the Early Cretaceous. PV article infos Published in Vol. 26, Fasc. 1-4 (1997) |

New late Paleocene rodents (Mammalia) from Big Multi Quarry, Washakie Basin,Wyoming.Mary R. Dawson and Christopher K. Beard
Published online: 12/16/96 Keywords: Clarkforkian; North America; Paleocene; Rodentia Abstract The earliest North American rodents occur in basal Clarkforkian beds of the Fort Union Formation at Big Multi Quarry near Bitter Creek, northern Washakie Basin, Sweetwater County, Wyoming, and in closely correlative Fort Union beds formerly accessible in the Eagle Coal Mine near Bear Creek, northern Clark's Fork Basin, Carbon County, Montana. Two new species of early Clarkforkian rodents, Paramys adamus and Alagomys russelli, are described from Big Multi Quarry. Paramys adamus is represented by virtually complete upper and lower dentitions, which demonstrate that this species is one of the most primitive North American paramyids yet discovered. These specimens form the basis for a reevaluation of the content and stratigraphic range of P. atavus, which is known with certainty only from Bear Creek. Alagomys russelli is the first North American record for the enigmatic rodent family Alagomyidae, otherwise known from ?late Paleocene-early Eocene localities in Mongolia and China. Phylogenetic analysis of dental and gnathic traits suggests that Alagomyidae form the sister group of all other undoubted rodents. At least two rodent clades, alagomyids and basal paramyids, seem to have invaded North America from Asia at the beginning of Clarkforkian time, but only the paramyids persisted to undergo a significant evolutionary radiation in North America.

First record of the genus Megaderma Geoffroy (Microchiroptera: Megadermatidae) from Australia.Suzanne J. Hand
Published online: 6/14/95 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.
