The sudden appearance of modern cricetids in Europe during the Early Miocene was one of the most significant mammalian events of European Neogene. A characteristic representative of this mammalian turnover was the genus Megacricetodon that quickly became major components of the rodent faunas across Europe. Here, we review the fossil record of this...

The lower incisor enamel microstructure of the fossil rodent family Eomyidae was believed to be three‐layered and highly derived but rather uniform throughout the clade. Here, we describe a new four‐layered schmelzmuster in Eomyidae consisting of a three‐fold portio interna with longitudinal oriented, uniserial Hunter‐Schreger bands and a one‐fold...

The Amphicyoninae of the early Miocene from the locality of Tuchořice, the Czech Republic, are represented by three species. Two of them are classified within the tribe Amphicyonini: Paludocyon bohemicus (scHlosser, 1899) as the type species of Paludocyon n. gen., and a large-sized amphicyonid determined as Megamphicyon carnutense (anTunes et Ginsb...

The original fossil record of Allosorex stenodus Fejfar, 1966 from Ivanovce (late Ruscinian, MN 15b) is redescribed and supplemented by the description of so far unpublished fossil remains, including upper dentition (P4 and M3) and a humerus fragment as well as the enamel microstructure analysis of m2. Based on the critical evaluation of other foss...

New Amphicyonidae fossil remains from the early Miocene site of Tuchořice (the Czech Republic) confirm the presence of a new Thaumastocyoninae taxon: Peignecyon felinoides n. gen. et n. sp. It is characterized by a peculiar combination of plesiomorphic and derived morphological traits. The new genus can be defined by a long and sharp mandible diast...

The material of Machichnus regularis and Machichnus multilineatus was re-examined with respect to the potential tracemaker. New characters were defined for M. multilineatus – scratch profile with flat horizontal bottom and undulated microrelief of scratches. Based on these characters and additional information, both previously suggested tracemakers...

The locality of Akníkov 1 (Czech Republic, MN 3) has yielded the largest diversity of Dimylidae known from a single locality. Four species are recognised in the few dozen recovered fossils: Dimylus aff. paradoxus, Plesiodimylus sp., Chainodus intercedens and Lacrimodon vandermeuleni nov. gen., nov. sp. The high diversity supports the assumption of...

The fossil record of cervoid pecoran from the primate Pliocene site of Ivanovce (late Ruscinian, MN 15b) is described and discussed from taxonomical and ecological viewpoints. This rare fossil record represents probably an ancient (Late Miocene?) element surviving in the Early Pliocene European fauna. Its presence at the site confirms a previous vi...

The fossil record of large mammals (Ursidae, Mustelidae, Tapiridae, Bovidae, Probos- cidea) from the primate Early Pliocene site of Ivanovce (Late Ruscinian, MN 15) is described and discussed from both the taxonomical and ecological viewpoints. The Ivanovce site is an important locality with probably one of the latest occurrences of Agriotherium in...

Two Middle Miocene forms of Plesiodimylus are described from the Devínska Nová Ves-Fissures site (the Middle Badenian, MN 6). Whereas the smaller form represents the typical individuals of P . chantrei , the larger one represents a different new species ( P . similis sp. nov.) with an affinity to P . crassidens from the Anatolian Middle Miocene (MN...

On the basis of the evolutionary stage of the small mammal species and the faunal compositions we assign three Jabal Zaltan assemblages to the middle Early Miocene (18-19 ma) — one to the late Early Miocene (16-17 ma) and two to the Middle Miocene (14-15 ma) — in total covering approximately 4 million years.

The first well defined Pliocene mammalian faunas in the Czech Republic – found at localities Měňany 3 and Vitošov – are reported herein. Pilot samples from the localities have yielded an assemblage of at least 23 taxa of small mammals (Lipotyphla, Chiroptera, Lagomorpha, and Rodentia). The key taxa Mimomys hassiacus, M. cf. gracilis (an advanced fo...

Based on material from the fissure filling Gundersheim 4 (District Alzey-Worms, Rheinland-Pfalz, Germany), a Ruscinian small mammalian assemblage is described. Morphology and relations of significant species of Lagomorphs, Rodents and Insectivores is discussed. In the domain of Soricidae, the new subfamily Paenelimnoecinae is erected to accomodate...

The Ahníkov (Miocene, Czech Republic) site represents a concentration of vertebrate skeletal remains in a swamp setting. Autochthonous bone deposits were strongly altered by sedimentary processes and early diagenesis. Biting and gnawing traces recognized on hard animal tissues (bones, teeth, antlers, turtle thoraces) represent seven recurring morph...

The Czech locality of Merkur-Nord (MN 3) has yielded one species of erinaceid and five species of talpids. The hedgehogs are represented by a few fossils of Galerix only. The talpid assemblage is characterised by a dominance of Mygalea magna. The position of Mygalea within the Desmaninae, which previously had been open to some doubt, could be ascer...

A new genus of vespertilionid bat from Early Miocene of Jebel Zelten, Libya, with comments on Scotophilus and early history of vespertilionid bats (Chiroptera) Nový rod netopýra z basálního miocenu Džebelu Zelten, Libye, s poznámkami k rodu Scotophilus a rané historii vespertilionidních netopýrů (Chiroptera) Abstract. A well preserved mandible of a...

The small mammal assemblage obtained from six sites of the Miocene deposits in Jebel Zelten, Libya, in 1982, 1983 and 1997, is composed of 10 species of rodents (seven different clades), 2 spp. of ochotonid Lagomorphs and one vespertilionid bat. A special attention is given to the forms characterising the uppermost part of the series: they belong (...

Mammalian assemblages occur at the sites of Detan, Valec, and Dvérce in calcar- eous and volcanic clay layers at the southern margin of the Doupov Mountains along the Bohemian Rift. The age of the fossiliferous layer at Detan is early Oligocene (Stam- pian, Suevian), Biozone MP 21, and is K/Ar dated at 37.5 Ma. Mammalian bones and teeth are widely...

We describe the first dinosaur skeletal remains found in the Czech Republic, consisting of one complete femur and indeterminable bone fragments. They were recovered from the upper Cenomanian near-shore marine sediments deposited on the slopes of an ancient archipelago, several kilometres north of the larger Rhenish-Bohemian Island that was situated...

Introduction The fossil record of insectivores in Czech Republic comes from two different settings: A. in the stratified deposits in the North Bohemian tectonic rift (the sites; Tuchořice, the Open Mine Merkur-Nord near Chomutov, Dolnice and Františkovy Lázně (Franzensbad), and Β. in the karstic fillings at Suchomasty. The richest occurrence of ins...

Carnivores from two late Pliocene Slovak sites - Ivanovce (late MN 15) and Hajnáčka (early MN 16) are described and their taxonomy is discussed. In both sites, the ocurrence of the families Mustelidae and Procyonidae is similarly represented by Lutra cf. bravardi and Parailurus. However, both sites differ by the presence of Parailurus hungaricus, M...

The first micromammals are described from Eppelsheim, one of the classic localities of the Dinotheriensande (sands withDeinotherium) of Rheinhessen. The Dinotheriensande are the earliest deposits known of the Rhine river south of the Rhenian Slate Mountains (“Rheinisches Schiefergebirge”).Plesiosorex roosi n. sp. is described as new. The evolutiona...

Restos de micromamíferos de siete localidades han sido recogidas durante dos campañas de campo geológicas/paleontológicas (1983 y 1997). Las muestras son pequeñas pero se han reconocido y descrito doce especies que representan siete familias de roedores, una de lagomorfos y una de quirópteros. La fauna de mamíferos (macromamíferos) de Jebel Zelten...

Small mammal remains from seven localities were collected during two geological/paleontological field campaigns (1983 and 1997). The assemblages are small, but the twelve species recognized and described represent seven rodent families, one lagomorph and one bat family. The Jebel Zelten (large) mammal fauna was considered in most literature to repr...

Based on new evidence from the arvicolid record, the Arondelli local fauna of northern Italy is correlated with similar occurrences in Central Europe (Hajnácka, Wölfersheim, Hambach, Gundersheim), Russia (Uryu 1) and Anatolia (Kadiözü, Ziyaret, Yenice-1). The similarity with the Hambach fauna in the normally polarized Reuver clay establishes the co...

The staircase-like aggradation river terraces which contain, together with the overlying loess blankets and intervening palaeeosol complexes, a practically complete record of the entire Quaternary, are typical of the inner uplands of the Bohemian Massif. Despite of doubtless relative stratigraphy of well-defined local Quaternary sequences, the cali...

More than 1000 isolated molars of the advanced cricetids with high-crowned molars (the subfamilies Arvicolinae; the “microtoid” Baranomyinae, Prometheomyinae and Trilophomyinae) from the early Pliocene (MN 15b) in the lignite quarry “Römerstraße” at Wölfersheim in the Horloff Basin about 30 km north-east of Frankfurt am Main represent the following...

A new fauna of small vertebrates found in glacial gravels ("Höhere Deckenschotter") at Irchel-hill (Kt. Zürich, Switzerland) suggest a deposition age of late Pliocene (MN 17).

In the Interandean Depression of northern Ecuador (Carchi Province), more than 50 m of pyroclastic and windblown deposits (Cangahua Formation) were deposited during the cold phases of the Quaternary, interrupted many times by the development of evolved paleosoils during interstadials. The deposition occurred during downcutting if the plateau and co...

The Tertiary VP sites of Czechoslovakia cover the time span since late Eocene with gaps in the middle-late Oligocene and late Miocene (MP 22-MN 2; MN 7, MN 8, and MN 10–13). The Neogene faunal sequence includes occurrences of general importance: (1) the MN 3b fauna of the riparian gallery forest in the base of the brown coal seam in the north Bohem...

The Upper Ruscinian (MN 15) has a meager record in northern central Europe. Our knowledge of Ruscinian rodents from Germany is restricted to the local faunas of Wölfersheim near Frankfurt and — supposedly — of Gundersheim near Worms. They are of some common interest because of their geographical position. Within Europe they show affinities to well...
