Les serpents des phosphorites du QuercyJean-Claude Rage
Published online: 20/12/1974 Keywords: Grande Coupure; Quercy Phosphorites; Serpents https://doi.org/10.18563/pv.6.3-4.273-303 Abstract A short review of the genera and species of snakes from the Quercy's phosphorites described by former authors is followed by the study of specimens recently collected. Most of these latter specimens belong to the Aniliidae, Boidae, Colubridae and to the Scolecophidia; the precise systematic position of some of them is not defined yet. The following genera and species are described: Eonilius europae nov. gen. and nov. sp., Platyspondylia lepta nov. gen. and nov. sp., Coluber cadurci nov. sp. and Dunnophis cadurcensis nov. sp.; a species described by de Rochebrune (Palaeopython filholi) is revised. One of the most important conclusions of this study is that the Colubridae appear as early as the Upper Eocene. The stratigraphic repartition of these snakes shows that the rich Upper Eocene fauna is followed by the very reduced fauna of the Lower Oligocene; then the oligocene «Grande Coupure» corresponds to a very important faunistic renewal. The fauna remains poor and little diversified during the beginning of the Middle Oligocene after which there is a new faunistic explosion. PV article infos Published in Vol. 06, Fasc. 3-4 (1975) |

Un nouveau genre de ?Palaeotheriidae (Perissodactyla, Mammalia) décelé dans les phosphorites du Quercy (Eocène supérieur ou Oligocène) d'après un arrière crâne sans dents.Jean-Albert RemyPublished online: 15/06/1999Keywords: endocranial cast; Epitympanic sinus; Palaeotheriidae; Paléogène; Quercy Phosphorites; skull anatomy Abstract A rear skull from the Quercy Phosphorites is described. It documents a new perissodactyl genus, likely assignable to the family Palaeotheriidae and probably paleogene of age. Owing to the lack of any tooth, this family assignment remains however somewhat hypothetical. The specimen is firstly characterised by the presence of a wide epitympanic sinus swelling and hollowing the squamosal shell and the post-glenoid process. This cavity might make up a peculiar pattern of improvement for the hearing apparatus by carrying out a kind of drum near the middle ear, whereas the bony tympanic remains barely bulged and forms but a few developed auditory bulla. This pattern appears an outcome of a trend observed with many palaeotheriids, such as Plagiolophus. Furthermore, the endocranial cast shows a rather high degree of gyrencephaly for a paleogene mammal. The prominent lambdoidal crest points out a powerful nape musculature and a lowered head bearing. Consequently, it is assumed that such an animal was probably living in somewhat open places, at the expense of rather tough vegetables. It might have been accordingly provided with a semi-hypsodont, cement covered, "plagiolophoid" dentition. PV article infos Published in Vol. 28, Fasc. 1 (1999) |

Modification du statut générique de quelques espèces de sélaciens crétacés et tertiairesHenri Cappetta
Published online: 15/12/1980 Keywords: Cretaceous; Selachians; Tertiary https://doi.org/10.18563/pv.10.1.29-42 Abstract The re-examination of six fossil selachian species has involved the creation of six new genera: Squatiscyllium, Protolamna, Parotodus, Abdounia, Physogaleus, Hypolophodon and of one new species : Prozolamna sokolovi. The modification of the generic statute of these species allows to clarify their systematic position and to define their relationships at a familial level.

Evolution des Aplodontidae Oligocènes EuropéensNorbert Schmidt-Kittler and Monique Vianey-Liaud
Published online: 01/10/1979 Keywords: Aplodontidae; Europe; Oligocene https://doi.org/10.18563/pv.9.2.33-82 Abstract Until now Aplodontidae of the European Oligocene have been documented by four species only. The phylogenetic relations remained obscure. as the distribution of only one species has been known in some detail. New material made it possible to define the stratigraphic range of two of the already existing species (Plesispermophilus angustidens, Sciurodon cadurcense) and to follow their development during the Oligocene beginning with the event of the « Grande Coupure ››. Sciurodon remained nearly without change until the end of the Middle Oligocene. Plesispermophilus angustidens split into two distinct phyletic lines, one of which (P. macrodon n. sp.) reaching considerable size, is represented till the beginning of the Upper Oligocene (Pech de Fraysse, Gaimersheim). The other line leads to Plesispermophilus ernii (basal Upper Oligocene of Burgmagerbein 1. terminal Upper Oligocene of Coderet). Besides the already known forms a new small-sized species (P. atavus n. sp.) is described, which by its primitive features closely resembles the genus Plesispermophilus. Two other small-sized species already known from the Upper Oligocene (? P. argoviensis) and Lower Miocene (? P. descedens) seem to be closely related to the new species. It cannot be decided whether they are descendents of this line or have developed independently, because of their poor fossil record. PV article infos Published in Vol. 09, Fasc. 2 (1979) |

Contribution à la classification des pistes de vertébrés du Trias: Les types du Stormberg d'Afrique du Sud (1).Paul EllenbergerPublished online: 16/10/1972Keywords: Footprints; South Africa; Stormberg; Trias https://doi.org/10.18563/pv.5.ext Abstract Cet article explore les pistes fossiles de vertébrés du Stormberg (Trias, Afrique du Sud), révélant une diversité ichnologique inédite avec 64 ichnotypes classés en tridactyles, tétradactyles et pentadactyles. Les découvertes incluent des reptiles bipèdes comme Qemetrisauropus et Prototrisauropus, dont les empreintes suggèrent des adaptations évolutives vers la bipédie, ainsi que des pentadactyles géants comme Pentasauropus, annonçant les futurs sauropodes. L’étude combine ichnologie et restes osseux pour reconstituer des écosystèmes triasiques riches, où flore (fougères, conifères) et faune témoignent d’une transition écologique majeure avant l’essor des dinosaures.

Functional aspects of the evolution of rodent molarsPercy M. ButlerPublished online: 01/10/1980Keywords: Chewing; Muridae; Rodents; Wear facets https://doi.org/10.18563/pv.9.ext.249-262 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) |

Lower Paleogene crocodilians from Silveirinha, Portugal.Miguel T. Antunes
Published online: 15/10/2003 Keywords: ?Upper Paleocene / Lowermost Eocene; Crocodilians; Ecology; Portugal Abstract The presence at Silveirinha of one of the earliest, ? Late Paleocene or Lowermost Eocene, european representatives of the genus Diplocynodon is based mostly on isolated bones and teeth (often from juveniles). This small-sized form is the only crocodilian so far recognized in this site. The longevity of Diplocynodon in Portugal becomes much extended; the genus survived there until the Middle Miocene at least. A discussion on the possible affinities with other eocene Díplocynodon and especially those from Cubillos-Valdegallina (Zamora, Spain) is presented. On the other hand, differences have been detected in comparison with: Díplocynodon tormis, from the middle Eocene of the Douro basin in Spain, which may belong to another phyletic line; and the aff. Diplocynodon from Dormaal (Belgium) and Le Quesnoy (France), nearly contemporaneous of Silveirinha. The Silveirinha Diplocynodon and many other data strongly suggest moist, subtropical, quite limited in space environments related to an alluvial plain crossed by small, meandering channels.

Contributions à l'étude des micromammifères du gisement Miocène supérieur de Montredon (Hérault). 2- Les rongeursJean-Pierre AguilarPublished online: 30/06/1982Keywords: Hérault; Late Miocene; Micromammals; Montredon; Rodents https://doi.org/10.18563/pv.12.3.81-117 Abstract The recent excavation of the Upper Miocene locality of Montredon (Hérault) provides a rich material of Mammals. The present study deals with rodents. The new quarry is 10 meters above the classical Depéret's Quarry. No differences have been noticed between the rodent populations coming grom these two sites. The description of two new species : Hispanomys mediterraneus and Muscardinus heintzi is given and the dormouse Eliomys is recorded there for the first time. The new zonation of the Miocene given by Aguilar (1982) and the previously established correlations between marine and continental chronological scales give Tortonien age (estimated between 9 and 10 M.Y. old) to the site of Montredon, which belongs to the Mammal zone D 2.

Les mammifères de Rians (Eocène inférieur, Provence)Marc Godinot
Published online: 01/02/1981 Keywords: Eocene; Mammals; Provence; Rians https://doi.org/10.18563/pv.10.2.43-126 Abstract The fossil mammals discovered in the quarry of Rians (Sparnacian, Provence) are described. Among these forms, Hyracotherium is interesting because of the little molarization of the lower premolars and its small size, and Diacodexis by its small size and very primitive astragalus ; they may be the most primitive representatives of their respective orders. Also, Proviverra eisenmanni n. sp. is the smallest and most primitive hyaenodontid yet described. Hyopsodus itinerans is the first species of this genus described France. Among other rare fossils is a new species of bat, a small palaeoryctid, and other forms not yet identified. Marsupials are varied. Several new species are present among the rodents. The fauna is well-balanced and rich in small hyopsodontid condylarths. It is stratigraphically situated at the PV article infos Published in Vol. 10, Fasc. 2 (1981) |

La poche à phosphate de Ste-Néboule (Lot) et sa faune de vertebres du Ludien supérieur. 8- Insectivores et Chiroptères.Bernard SigéPublished online: 25/09/1978Keywords: Eocene; Quercy Phosphorites https://doi.org/10.18563/pv.8.2-4.243-268 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) |

Ein neuer condylarthre und ein tillodontier (Mammalia) aus dem Mitteleozän des Geiseltales.Jens L. Franzen and Hartmut HauboldPublished online: 15/04/1986Keywords: Condylarthra; Eocene; Europe; Mammalia; taxonomy; Tillodontia https://doi.org/10.18563/pv.16.1.35-53 Abstract In the course of a revision of the Equoidea numerous dentitions as well as a partial skeleton of a Phenaeodont were discovered from the Middle Eocene lignite beds of the Geiseltal locality. These fossils are recognized as a new genus and species of Phenacodontidae : HaIlensia matthesi n.g. n.sp.. The species is present in the « untere und obere Unterkohle ›› (uUK, oUK = the lower and upper part of the Lower Coal Seam) as well as in the « obere Mittelkohle ›› (oMK = the upper part of the Middle Coal Seam). Two fragmentary upper jaws described and figured by Matthes (1977) as Propachynolophus gaudryi are also belonging to Hallensia matthesi. Thus the decisive argument for classifying the " Unterkohle " of the Geiseltal section as Lower Eocene has to be dropped. Another relict form of the Geiseltal is Esthonyx tardus n. sp. documented by a fragmentary mandible coming from the « untere Unterkohle ››. This is the latest Tillodont from Europe. Contrasting to E. munieri from the european Lower Eocene the dentition of E. tardus is morphologically more progressive. PV article infos Published in Vol. 16, Fasc. 1 (1986) |
