While the swabian and franconian karsts of southern Germany have yielded rich and important neogene vertebrate faunas, the middle to late Miocene transition is still extremely underrepresented. This period is however key for the understanding of the European mammal evolution. A microtoid rodent Microtocricetus M2 is described and commented in this...

Large-sized cricetid rodents (Cricetodotontini) immigrated to Central Europe at the beginning of the Middle Miocene Climate Transition at ca. 15 My and are thus of great value for biostratigraphic and palaeoecologic purposes. An important fossil material belonging to a relatively small species of Mixocricetodon from the North Alpine Foreland Basin...

The maxillary presented in this work has been excavated in the middle Miocene karst filling Petersbuch 136 (Germany, Bavaria) and shows the oldest evidence of dental anomaly in a sciurid. The aberrant morphology, probably hyperdontia or no replacement of roots of deciduous teeth, affects the area of the P3, a tooth that is generally not well docume...

Fossil bats are described from the karstic deposits of the Erkertshofen 1, Erkertshofen 2 and Petersbuch 2 sites in eastern Bavaria, southern Germany (MN 4). Fossils are discussed with regard to taxonomic, stratigraphic and palaeoecologic significance. The rich fossil material represents at least 12 different bat species belonging to Megadermatidae...

Fossil bats are described from deposits of the Upper Freshwater Molasse of the Forsthart and Rembach sites in East Bavaria of South Germany (MN 4). The material comprises 13 fragments, representing at least six different species, all belonging to Vespertilionidae. A fossil form from Rembach, close to the Oriental clade of Hesperoptenus , represents...

Four species of Ophisaurus , O . fejfari , O. spinari , O. robustus and O. holeci , are recognized on the basis of parietals from the Early Miocene of the Czech Republic and Germany. The fifth species, O. acuminatus , is described from the Late Miocene of Germany, but its parietal is not preserved. This paper describes new O . fejfari , O. spinari...

The recent advances regarding the complex chronobiostratigraphy of Middle Miocene terrestrial deposits of southern Germany are reviewed. We propose new and revised cor-relations between the Swiss and South German faunas framework for ongoing research.We restrict our analysis to the cricetid and microtoid muroid rodents, especially theMegacricetodon...

In the Miocene, the talpid diversity was much higher than today. Especially the semifossorial and ambulatory moles were farther distributed and more common. Here, the talpids from the Bavarian fissure filling Petersbuch 28 (Early Miocene, MN 3) are described. The uropsiline Desmanella engesseri Ziegler, 1985 is the most frequent species, followed b...

The only marsupial and the Erinaceidae from the Bavarian fissure filling Petersbuch 28 are described. The marsupial is Amphiperatherium frequens erkertshofense, the Erinaceidae are represented by Galerix aurelianensis and an unknown large galericine, which is present only by four isolated teeth. The three species are mostly present by single teeth;...

The Bavarian fissure filling Petersbuch 28 (Lower Miocene, MN 3/4) yielded a large assemblage of the dimylid Plesiodimylus aff. chantrei. This assemblage includes molars of three incompletely differentiated morphotypes, resembling Plesiodimylus huerzeleri, P. chantrei and P. bavaricus, respectively. This pattern is interpreted as due to ecological...

The dP4 of Desmanella engesseriZiegler, 1985 from a maxillary which includes the P2 and P3 in crypt, the P4 in eruption and fully erupted dP4 and M1, is described from Petersbuch 28 (Germany; Lower Miocene, MN3/4). The maxillary was studied using X-ray microtomography to make detailed images of the internal and external features of the sample. This...

The bats from the Petersbuch 28 and 62 fossil localities include 10 species of Rhinolophidae, Megadermatidae and Vespertilionidae families. Three taxa are new: Hanakia agadjaniani nov. sp., Miostrellus petersbuchensis nov. sp. and Plecotus schoepfelii nov. sp. In both taphocenosis the rhinolophids predominate, especially Rhinolophus lemanensis. P....

Dans la faune des soricidés du remplissage de fissure bavarois Petersbuch 28, Allemagne, Miocène inférieur, des spécimens de Miosorex desnoyersianus (Lartet, 1851) et Paenelimnoecus micromorphus (Doben-Florin, 1964) conservent une pénultième antémolaire (a2) minuscule. Cette antémolaire était auparavant inconnue chez P. micromorphus. Le nombre diff...

Le remplissage de la fissure bavaroise Petersbuch 28 (Miocène inférieur, MN 3/4, Allemagne) a livré une faune diversifiée de musaraignes. Les taxons Soricella discrepans Doben-Florin, 1964 et Paenelimnoecus micromorphus (Doben-Florin, 1964) présentent une distribution bimodale pour certaines variables dentaires que nous interprétons ici comme la co...

A revision of the Early-Middle Miocene anguine, Pseudopus laurillardi (Lartet, 1851), is presented based on a detailed anatomical analysis of one newly discovered articulated specimen and numerous disarticulated cranial and postcranial elements from several localities in Germany, as well as on the restudy of the original skeletal material of Lartet...

We herein present Collimys populations from German localities and introduce one new species: C. hiri sp. nov. The important biostratigraphic value of this genus is demonstrated based on at least two evolutionary lineages characterized by an increase in molar size. The first lineage (hiri/dobosi lineage) is presented in this paper and is found aroun...

The small and medium-sized Cricetidae (Rodentia, Mammalia) from the fissure filling Petersbuch 68 (Frankonian Alb, southern Germany) are described. The fissure infill is biostratigraphically heterogeneous and probably reflects the result of two successive deposits. The older sample comes from in the middle part of the fissure and contains species c...

New fossil material of the genus Collimys (Rodentia, Mammalia) from the fissure fillings of the Frankian Alb (South Germany) is described and the new species C. gudrunae is introduced. This species is integrated in the new C. transversus / C. gudrunae lineage which is restricted to the Middle Miocene (MN 7, base of MN 8?) and contains three distinc...

The erinaceid teeth from the fissure filling Petersbuch 68 can be divided into two taxonomically and biostratigraphically independent groups. The specimens from the middle part of the fissure filling (MN 5) represent one species (Galerix cf. symeonidisi), whereas the fauna from the upper part of the filling is more diversified, containing four spec...

A skull and associated postcranial material of a small beaver species from the fissure filling Petersbuch 50 in Bavaria is described. The associated fauna indicates an age of MN 8. Systematically the beaver is close to Trogontherium due to the elongated upper M3, but differs substantially from it in lacking the striated enamel on the incisors. Thus...

The small mammals from Çandir Loc. 2 are described. The rodents are represented by six families with thirteen species, the lagomorphs by one family with two species and the insectivores by four families with four species. The diverse rodent association with species that are endemic for the eastern Mediterranean area as well as species that are know...

The genus Cricetodon was found in several Miocene localities in the Swiss molasse, which had been discovered in the last years. A comparison of these species with Cricetodon material from the molasse of Southern Germany and from fissure fillings in the Frankenalb showed similarities on the species level. From the locality Chräzerentobel 505m a new,...

In several carst and molasse faunas of the middle Miocene a large species of Cricetodon is represented for which different names have been used in the literature. Comparisons with other representatives of the genus Cricetodon indicate a new species named herein. Cricetodon jumaensis n. sp. to our current knowledge is restricted to the biostratigrap...

An extensive collection of Miocene material of the genus Cricetodon has been discovered in a variety of hitherto unreported fissure fillings of the Franconian Alb. The findings are morphologically comparable with the respective dentitions of Cricetodontini, from southern German sites and from different locations as well. Five different species were...

A new genus and species of epoicotheriid,Molaetherium heissigi, is described from the Early Oligocene of Grafenmühle 22, near Pappenheim, Bavaria. It is a tiny, highly fossorial form, closely related to the North American genusEpoicotherium. Asia is considered the center of origin of the suborder Palaeanodonta; from there it dispersed to North Amer...

A new genus of Cricetodontini from three Middle Miocene fissure fillings near Petersbuch (Fränkische Alb) and three sites of the Bavarian Molasse is described. The variability of features and a delimitation against relevant Cricetodontini is given. The especial situation of the sites is shortly reminded.

A new species of Cricetodontini from an Upper Miocene fissure filling near Petersbuch (Frankische Alb) is described. The variability of features and a definition in contrast to relevant Cricetodontini are given, and the palaeocology of the site is described. -from English summary
