Article
We analyse the changes in rodent regional assemblages based on 657 fossil-bearing western European localities distributed ranging from ca. 27 Ma (Late Oligocene) to ca. 3 Ma (Late Pliocene). We compare temporal and spatial patterns in order to identify the factors that drive the evolutions of communities. Regional assemblages are analysed based on...
Article
Here we report a new early Oligocene cricetid, Paracricetops virgatoincisus, gen. et sp. nov., discovered from the Caijiachong locality in Yunnan Province, China. This new cricetid shows a peculiar combination of characters, such as massive and transversely positioned cusps, crenulated cheek tooth enamel, and a deep fossette enclosed between protoc...

Microtoid cricetids are widely considered to be the ancestral form of arvicoline rodents, a successful rodent group including voles, lemmings and muskrats. The earliest previously known microtoid cricetid is Microtocricetus molassicus Fahlbusch and Mayr 1975 from the MN9 (about 10-11 Ma) of Europe. Here we report a new microtoid cricetid, Primopris...
Article
We report new discoveries of eomyid rodents from the Valley of Lakes (Central Mongolia) yielded by diverse layers ranging in age from the Early Oligocene (local biozone A) to the Late Miocene (local biozone E). The remains of eomyid rodents are relatively rare compared to other groups of fossil rodents found in the same region. All together, eight...

Rodents of the extant family Gliridae, commonly called dormice, are common in European faunas since the early Eocene. Here we study for the first time specimens from St-Martin-de-Castillon C (France, early Oligocene) previously reported as Gliravus aff. majori and Pseudodryomys aff. fugax. We now refer them to Butseloglis tenuis and Microdyromys mi...

The late Oligocene faunas from central France are often rich and provide crucial information for understanding the evolution of mammals during the Oligocene-Miocene transition. The locality of Coderet-Bransat, where Amphechinus arvernensiswas so far the only known hedgehog, yielded new specimens hitherto identified as Galerix minor and Amphechinus...

The Miocene sands of the Swiss Jura Mountains, long exploited in quarries for the construction industry, have yielded abundant fossil remains of large mammals. Among Deinotheriidae (Proboscidea), two species, Prodeinotherium bavaricum and Deinotherium giganteum, had previously been identified in the Delémont valley, but never described. A third spe...

In Asia, the first find of an eomyid rodent was reported almost one century after the first studies of the family Eomyidae in North America and Europe. Since then, eomyid rodents have been increasingly found in Asia particularly over the past two decades. Here, we review the Asian record of this family at the genus level. Currently, 22 species with...

About a century ago, in 1909, the paleontologist Hans Georg Stehlin described, based on the European mammalian fossil record, “the greatest and most sudden change known so far during the tertiary times”. He underlined the correlation of this terrestrial event to the Eocene/Oligocene boundary and named it “Grande Coupure”. Recently, a biostratigraph...

Article
Simplomys, a dormouse with a simple dental morphology compared to other glirids, shows a continuous evolution in Spain during the end of the Ramblian and up to the middle Aragonian, the stratigraphic frame considered in this work. In contrast, the record of the genus in Central Europe is reduced to a few localities spanning from the early to the mi...

Amynodontidae is a family of Rhinocerotoidea (Mammalia, Perissodactyla) known from the late Early Eocene to the latest Oligocene, in North America and Eurasia. European Amyno-dontidae are very rare, and all remains belong almost exclusively to a single post-Grande Coupure genus from the Oligocene, Cadurcotherium. The "Grande Coupure" defines an ext...

Conference Paper
Full-text available
Perissodactyls are one of the major groups affected by the Grande Coupure event (Eocene-Oligocene transition) in Europe. Palaeotheriidae went almost extinct during this crisis, whereas Rhinocerotidae appeared for the first time in Europe after this biogeographical event. Knowledge on fossiliferous Eastern-European localities around this period is c...

Central Asia is a key area to study the impact of Cenozoic climate cooling on continental ecosystems. One of the best places to search for rather continuous paleontological records is the Valley of Lakes in Mongolia with its outstandingly fossil-rich Oligocene and Miocene terrestrial sediments. Here, we investigate the response by mammal communitie...

The Oligocene fossil deposits from Valley of Lakes in Central Mongolia have provided a wealth of rodent fossils. Among these, cricetids are a very important part. To date, only the Miocene genera have been described in detail. Here, we focus on the Oligocene genus Eucricetodon from this region. Eucricetodontinae are the most abundant fossils in the...

Whether or not evolutionary lineages in general show a tendency to increase in body size has often been discussed. This tendency has been dubbed “Cope's rule” but because Cope never hypothesized it, we suggest renaming it after Depéret, who formulated it clearly in 1907. Depéret's rule has traditionally been studied using fossil data, but more rece...
Article
Excavations of two fossiliferous layers in the Wallenried sand- and marl pit produced a very diversified vertebrate fauna. New material allows the reassessment of the taxonomic position of the ruminant taxa Andegameryx andegaviensis and endemic Friburgomeryx wallenriedensis. An emended diagnosis for the second species is provided and additional mat...

Additional specimens of the poorly known African shrew Lartetium africanum (Lavocat, 1961) are described and complete our knowledge of this tiny animal. The results of this study justify the elevation of material originally described as a subspecies to the species rank. Soricids are hitherto unknown in older African localities. Like many other sori...
