Présence de Palaeobatrachidae (Anura) dans des gisements tertiaires Français caractérisation, distribution et affinités de la famille
Colette Vergnaud-Grazzini and Robert Hoffstetter
Keywords: Anura; Palaeogeography; Systematics
 
  Abstract

    The Palaeobatrachidae until now have not been reported from France. The present note makes known the discovery of very significant remains in three Tertiary localities of France: Cernay (late Paleocene), Laugnac (late Aquitanian) and Sansan (middle Helvetian). The osteologic characters, as well as the geographic and stratigraphic distribution of the family are re-stated with added details. The Palaeobatrachidae are a European family known from the late Jurassic of Catalonia (publication in course by J. Seiffert) to the Plio-Pleistocene (pre-Mindel) of Poland and Rumania. By their way of life and certain osteologic characters they are similar to the Pipidae, but they are distinguished by profound differences. It would be rash to include them in the Pipoidea or even in the Aglossa. They are apparently an independant group, essentially holarctic, which held in Europe a role equivalent to that played by the Pipidae south of Tethys.

Strange Eocene rodents from Spain
Pablo Pelaez-Campomanes and Nieves Lopez-Martinez
Keywords: Biogeography; Eocene; PHYLOGENY; Rodents; Spain; Zamoramys extraneus n. gen. n. sp.
 
  Abstract

    A new European rodent from the middle Eocene of Spain, Zamoramys extraneus n. gen., n. sp., appears to be closely related to the middle Eocene chapattimyid rodents of Indo-Pakistan. This contradicts the generally accepted paleobiogeographic hypothesis of a Tethyian barrier between Europe and Asia isolating Europe during the middle Eocene. Because of this barrier, some authors have proposed that European and Asian rodents were not closely related, their similarity being the result of morphological convergence. Here monophyly has been tested, using the parsimony criterion, based on an analysis of dental characters (including discussing of homology and the validity of some characteristics). Our results indicate a phylogenetic relationship among the Asiatic Ctenodactyloidea, Zamoramys from Spain, and the European endemic Theridomyoidea. We also conclude from our analysis that theridomyoids and European ischyromyoids are probably not closely related phylogenetically.

Ein neuer condylarthre und ein tillodontier (Mammalia) aus dem Mitteleozän des Geiseltales.
Jens L. Franzen and Hartmut Haubold
Keywords: Condylarthra; Eocene; Europe; Mammalia; taxonomy; Tillodontia
 
  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.

Les gangas (Aves, Columbiformes, Pteroclidae) du Paléocène et du Miocène inférieur de France.
Cécile Mourer-Chauviré
Keywords: Birds; evolution; Lower Miocene; New taxa; Oligocene; Paleoecology; Paulhiac; Quercy Phosphorites; Saint-Gérand-Ie-Puy; Sandgrouse; Upper Eocene
 
  Abstract

    The two species of Sandgrouse from Quercy, Pterocles validus MILNE-EDWARDS and P. larvatus MILNE-EDWARDS, are ascribed to the genus Archaeoganga MOURER-CI-IAUVIRÉ which includes a third, very large species, A. pinguis. The sandgrouse of Saint-Gérand-le-Puy, Pterocles sepultus MILNE-EDWARDS, is ascribed to a new genus, Lepzoganga. This form appears in the Upper Oligocene of Quercy, in Pech Desse and Pech du Fraysse localities, and is still present in the Lower Miocene of Saint-Gérand-le-Puy and Paulhiac. Recent sandgrouse live in semidesert or desert areas. The indications provided by mammal and bird faunas in the localities where sandgrouse were found, confirm that the paleoenvironment was open and arid. The morphological study of these fossils indicates that, in the Upper Eocene, the Pteroclidae were already completely individualized with respect to Charadriiformes.

Etude du crâne de Pachynolophus lavocati n. sp. (Perissodactyla, Palaeotheriidae) des Phosphorites du Quercy
Jean-Albert Remy
Keywords: Perissodactyla; Quercy Phosphorites

doi: 10.18563/pv.5.2.45-78
 
  Abstract

    The genus Pachynolophus, one of the poorest known of the Palaeotheriidae, includes the brachyodont forms with reduced and non-molariform premolars and with upper molars lacking a mesostyle. Quantitative characters (divers surface indications and elongation of the teeth), while demonstrating a close relationship to Hyracotherium, permit a better differentiation of the genus, confirm its specific splitting, and permit the distinction of three lineages. The skull from Memerlein is taken as the type of a new species, P. Iavocati, of which the dentition is extremely characterized by its lophiodonty, the strong reduction of the premolars and the reduction of the cingula. This characterization testifies to a late age which extends the existence of the genus quite near to the Eocene-Oligocene limit. Compared with the only two skulls known of related species (Hyracotheríum vulpiceps and Pachynolophus Iivinierensis), that from Memerlein is distinguished by progressive characters affecting diferent regions but most particularly the braincase; it is not possible, however, to isolate within this evolution the part which leads to a systematic differentiation. Modernization is translated by a considerable increase in size of the braincase, principally in the frontal region, a development of the facial region with anterior displacement of the dental series and a greater specialization of the masticatory apparatus. This evolution parallels the history of the Equidae of the North American early Tertiary, but certain particularities, the form of the alisphenoid, the presence of an anterior frontal foramen, and the structure of the paroccipital apophysis, testifies to the independance of the European forms.

Un giraffidae dans le pliocène de Montpellier ?
Claude Guérin
Keywords: Artiodactyla; France; Giraffidae; Mammalia; Montpellier; Ruscinian
 
  Abstract

    An upper giraffid premolar without any indication about its origin is preserved at the Montpellier University among numerous fossils from the ruscinian formation of Montpellier. It can be related to Samotherium, of the Upper Miocene in Eastern Europe, North Africa and Asia, or more probably to Bramatherium  or Hydaspitherium of the Pliocene of South East Asia. The sedimentological study of the matrix shows a calcareous background, which may indicate that this tooth does not come from the Montpellier formation.

Nouveau Dichobunidae (Artiodactyla, Mammalia) du gisement d'Aumelas (Hérault) d'âge Lutétien terminal
Jean Sudre
Keywords: Aumelas; Dichobunidae; Hérault; Middle Eocene; Upper Lutetian
 
  Abstract

    The faunal list of the mammals collected at the locality of Aumelas (Hérault, France) is revised. For the first
    time this Middle Eocene locality is precisely settled in the european chronological scale of "niveaux repères", between the levels of Bouxwiller and Egerkingen, in Uppermost Lutetian.
    A new Dichobunid from the site is described : Aumelasia gabineaudi n. g., n. sp. This new genus has primitive characters. and it may be in the descent of the Lower Eocene Protodichobune

Lissamphibians from Dams (Quercy, SW France): Taxonomic identification and evolution across the Eocene-Oligocene transition
Alfred Lemierre and Maeva J. Orliac
Keywords: Eocene-Oligocene; Grande Coupure; Lissamphibia; Quercy Phosphorites

doi: 10.18563/pv.48.1.e3
 
  Abstract

    The locality of Dams (Quercy, southwestern France) has yielded two fossil assemblages, one from the late Eocene and another from the early Oligocene, making it one of the few localities with infillings across the Eocene-Oligocene transition. At least 24 taxa (13 mammals, 11 snakes) have been identified in this locality. Study of the lissamphibian remains from Dams yields an Eocene and an Oligocene assemblage, with a total of eight taxa. The Eocene assemblage includes two unnamed salamandrine species, one unnamed pelobatid species and one pyxicephalid species (Thaumastosaurus). The Oligocene assemblage includes two unnamed pleurodeline species, one salamandrine species (Salamandra sansaniensis) and an unnamed pelobatid species. Among the eight taxa from Dams, one Eocene salamandrine and one Oligocene pleurodeline are identified for the first time in the Quercy. A review of the lissamphibians from the Quercy area identifies eleven taxa for the Late Eocene (MP19) and eight taxa for Early Oligocene (MP22), with a major turnover at the Eocene-Oligocene transition. This turnover occurs in a time of major climatic changes, with a significant decrease in temperature and precipitation and concurrent increase in seasonality in Europe, likely affecting specialized taxa.

Les Gruiformes (Aves) des phosphorites du Quercy (France). 1. sous-ordre cariamae (Cariamidae et Phorusrhacidae), systématique et biostratigraphie.
Cécile Mourer-Chauviré
Keywords: Aves; Biostratigraphy; Birds; Cariamae; gruiformes; Quercy Phosphorites; Systematics
 
  Abstract

    The revision of the old collections of fossil birds from the “Phosphorites du Quercy” and the study of new material give the following results (Gruiformes, Cariamae) :  The humeri and most of the carpometacarpi described under the name Filholornis belong in Elaphrocnemus. The ulnae ascribed to Fïlholornis belong in Idiornis. Most of the post-cranial elements of the genera Elaphrocnemus and Idiornis are described and show great similarities with recent Cariamidae and Opisthocomidae, and fossil Bathornithinae.  A new genus and a new species, Oblitavis insolitus, are created in the sub-family Idiornithinae; two new species are described in the genera Elaphrocnemus (E. brodkorbz) and Idiornis (I. itardiensis), and the species Elaphrocnemus gracilis is transferred to the genus Idiornis.  The genus Propelargus Lydekker is transferred from the family Ciconiidae to Cariamidae.  A new generic name, Occitaniavis, is created for the species Geranopsis elatus, which belong in Cariamidae, while the type-species of the genus, Geranopsis hastingsiae, is a member of the Gruidae.  The affinities between the Quercy avifauna and the Neotropical one is emphasized by the occurrence of Phorusrhacidae, previously known only from the Cenozoic of South America and the Late Pliocene or Early Pleistocene of North America. Thanks to the material collected during the new excavations, the stratigraphical position of most of the species is stated precisely, and evolutionary lineages are outlined. This study shows that the suborder Cariamae, presently restricted to two South American genera, was already extremely diversified during the Eocene, and widespread in Europe and North America.

New datation of the Tafna Basin (Algeria): A combination between biochronological and magnetostratigraphical data
Salamet Mahboubi, Mouloud Benammi and Jean-Jacques Jaeger
Keywords: correlations; Late Miocene; North Africa; Rodentia

doi: 10.18563/pv.39.1.e1
 
  Abstract

    The Tafna Basin corresponds to the lowlands, which are located in front of Tessala and Traras ranges, below the Tlemcen mountains, Algeria. This basin displays a complete sedimentary cycle dominated by lagoonal-fluvial and marine deposits. The continental formations located at the base of these deposits are mainly composed of alternating sandstones and clays. An early late Miocene age has been previously attributed to them, based on direct correlations with marine deposits. Search for micromammal fossils led to the discovery of three different rodent species from a single level of the Djebel Guetaf section, located at the bottom of these deposits. The rodent assemblage indicates a late Miocene age. Combined magnetostratigraphical and biostratigraphical investigations were carried out to provide a more accurate age control of these continental deposits. Sixty-four oriented rock samples were collected for a magnetostratigraphic study along a 92 meters thick section including the fossiliferous layer. Rock magnetic investigations indicate the presence of both high and low coercivity minerals. Specimens subjected to progressive thermal demagnetization procedures show that the samples exhibit a high temperature magnetization component and display a normal polarity. Based on biostratigraphic constraints, the Guetaf section is correlated with Chron C4An, indicating an age ranging from
    9.1 to 8.7 Myr.

Une nouvelle espèce d'Hipparion du Miocène terminal d'Espagne.
Miquel Crusafont i Pairó and P. Sondaar
Keywords: Hipparion; Late Miocene; Spain; Villafranchian

doi: 10.18563/pv.4.2.59-66
 
  Abstract

    The recently discovered, very rich, Pliocene locality of Layna (Soria, Spain), has already yielded 30 species of mammals. Hipparion fissurae, described here is more dolichopodic than other Hipparion. It is related to Hipparion crusafonti from Villaroya (Villafranchian), but more slender between other characters.

L'occlusion dentaire chez Peradectes, Amphiperatherium et Peratherium, Marsupiaux du tertiaire d'Europe.
Jean-Yves Crochet
Keywords: Didelphidae; Eocene; Mastication; Oligocene; Wear facets
 
  Abstract

    The general principles guiding the study of wear facets which develop during mastication in mammals possessing tribosphenic molars are named. The application of this method of study to the molars of European Tertiary Didelphidae shows that the lineage of this family as represented by the species Peratherium cuvieri (Upper Eocene), P. elegans (Lower-middle Oligocene) and P. antiquum (Upper Oligocene) has propessively evolved toward a more carnivorous diet.

The beginning of the adaptive radiation of Theridomorpha (Rodentia) in Western Europe: morphological and phylogenetic analyses of early and middle Eocene taxa; implications for systematics
 
Monique Vianey-Liaud and Laurent Marivaux
Keywords: characters analyses; Dental morphology; Eocene; Rodentia; variability

doi: 10.18563/pv.44.2.e2
 
  Abstract

    This paper provides a revision of the early and middle Eocene European rodents previously referred to as Ischyromyoidea, including taxa considered to be at the origin of the Theridomorpha. The use of an accurate dental terminology and a better understanding of the size and shape of their infra-orbital foramen (i.o.f.) led us to a substantial revision of this group, which allowed to better characterize them and to appreciate their variability. On these bases, phylogenetic analyses (cladistic and standard Bayesian
    approaches) of early Ypresian to late Priabonian European rodent species were undertaken in order to highlight the root of the early Theridomorpha and its content. In this paper, the phylogeny was established based on 343 characters (338 dental) through 45 early Paleogene taxa using both cladistic and bayesian analyses. The ingroup included on one hand a few North American genera (Reithroparamys, Microparamys, and Acritoparamys) and European ones (Eogliravus, Ailuravus, Corbarimys, Meldimys, Euromys, Plesiarctomys, and Pseudoparamys) considered until now as being related with the North American superfamily Ischyromyoidea. On the other hand, it included genera close to the root of the Theridomorpha (Sparnacomys, Pantrogna, and Hartenbergeromys) and early Theridomyoidea (Masillamys, Protadelomys, and some Pseudosciuridae). The phylogenetic results obtained via the two
    distinct reconstruction approaches are consistent in virtually all relationships. The proposed systematics here derives from these phylogenetic results. This phylogenetic context led us to change the suprafamilial, familial, subfamilial or generic attribution of several species. Characters of Theridomorpha, like the obliquely developed postprotocristid allied with the occurrence of a metalophulid I, have been found in genera previously considered as Ischyromyidae (Pseudoparamys, Euromys, Sparnacomys, Meldimys, Pantrogna, and Hartenbergeromys) as well as the large i.o.f., when preserved (Pseudoparamys, Hartenbergeromys, and Masillamys). Based on these morphological observations and new phylogenetic considerations, the content of the Theridomorpha clade is here enlarged, thereby extending back the first theridomorph radiations to the early Eocene. Aside, a new taxon (Reinomys rhomboides gen and sp. nov.) is described from Avenay. In addition, a new genus, Auroremys, is created for the species subita (Comte et al., 2012) from Chery-Chartreuve.

Contributions à l'étude du gisement Miocène supérieur de Montredon (Hérault). Les grands mammifères. 7 - Les proboscidiens Deinotheriidae
Heinz Tobien
Keywords: allometry; Astaracian; Deinotherium; Montredon; Systematics; taphonomy; Vallesian
 
  Abstract

    Some complete tooth rows and about one hundred isolated teeth enabled the identification of the deinothere of the Vallesian site Montredon (Hérault) as Deinotherium giganteum KAUP 1829, mainly by comparisons with the likewise Vallesian sample of the type locality Eppelsheim (Rheinhessen, F.R.G.).
    Scatterdiagrams of the teeth show the importance of allometry during the phyletic size increase of the European deinotheres.
    Some taphonomic problems of the Montredon deinothere are briefly mentioned.

A new species of bat (Chiroptera: Vespertilionidae) from the early Oligocene global cooling period, Brule Formation, North Dakota, USA
Nicholas Czaplewski, Jeff Person, Clint Boyd and Robert Emry
Keywords: Eocene-Oligocene global cooling; Mammalia; Oligocene; Plecotini; Quinetia

doi: 10.18563/pv.42.2.e2
 
  Abstract

    We report the first confirmed fossil bats from North Dakota, including a new species referable to the Vespertilionidae represented by a maxilla with P4-M3 from the Brule Formation, Fitterer Ranch local fauna, early Oligocene, Whitneyan North American Land Mammal Age. Unassociated postcranial fragments of the humerus and femur also represent a vespertilionoid, but appear to reflect a different, unidentified species. The new taxon, Quinetia frigidaria sp. nov., is referred to the genus Quinetia, previously known only from approximately contemporaneous deposits in Europe. The new species is larger than Quinetia misonnei from the early Oligocene of Belgium. It is similar in some morphological characters to Chadronycteris rabenae (Chiroptera incertae sedis) of the late Eocene (Chadronian) of northwestern Nebraska and to Stehlinia species (?Palaeochiropterygidae) from the Eocene and Oligocene of Europe, but differs from each in morphological details of the dentition and maxilla. An unassociated talonid of a lower molar from Fitterer Ranch shows myotodont morphology, unlike the nyctalodont lower molars in Q. misonnei, and thus represents a second chiropteran taxon in the fauna. Quinetia frigidaria is a member of a Paleogene radiation of bats near the low point of the Eocene-early Oligocene decline in global temperatures, increased seasonal aridity, and loss of tropical floras from mid-latitude North America.
