New data on early Oligocene dormice (Rodentia, Gliridae) from southern Europe : Phylogeny and diversification of the family

Lu, Xiaoyu ; Costeur, Loïc ; Hugueney, Marguerite ; Maridet, Olivier

In: Journal of Systematic Palaeontology, 2021, p. 1-21

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 misonnei. Besides the French material, new...

Geochemical fingerprinting of key lithologies and depositional processes across the upper boundary of the Opalinus Clay (Aalenian, Middle Jurassic, northern Switzerland)

Lauper, Bruno ; Deplazes, Gaudenz ; Vogel, Hendrik ; Jaeggi, David ; Wohlwend, Stephan ; Ariztegui, Daniel ; Foubert, Anneleen

In: The Depositional Record, 2021, vol. 7, no. 1, p. 25-51

The Opalinus Clay is an argillaceous to silty mudstone formation, notable in Switzerland as the selected host rock for deep geological disposal of radioactive waste. Its upper bounding unit (Passwang Formation and eastern equivalents) is composed of successions of mudstone, sandy bioclastic marl and limestone separated by ooidal ironstone beds. The lithostratigraphic transition is diachronous...

Anchitheriinae (Perissodactyla, Equidae) from the early middle Miocene locality Gračanica (Bugojno Basin, Bosnia-Herzegovina)

Becker, Damien ; Tissier, Jérémy ; Vasilyan, Davit ; Göhlich, Ursula B.

In: Palaeobiodiversity and Palaeoenvironments, 2020, p. -

The early middle Miocene (European Land Mammal Zone MN5-earliest MN6) locality Gračanica (Bugojno Basin, Bosnia-Herzegovina) has yielded numerous well-preserved dental remains of two Anchitheriinae species: Anchitherium hippoides and Anchitherium ezquerrae. This anchithere assemblage is typical of the Orleanian European Land Mammal Age and is recorded for the first time in Southeastern...

Fish, amphibian and reptilian faunas from latest Oligocene to middle Miocene localities from Central Turkey

Vasilyan, Davit ; Roček, Zbyněk ; Ayvazyan, Anna ; Claessens, Leon

In: Palaeobiodiversity and Palaeoenvironments, 2019, vol. 99, no. 4, p. 723–757

In this paper, we describe ectothermic vertebrate assemblages from the Kargı 1, Kargı 2, Kargı 3, Harami1, Harami 3, Hancılı, Keseköy, Çandır and Bağiçi localities in Turkey. The ages of these localities range from the latest Oligocene to the middle Miocene. The preserved non-mammalian fauna of the studied localities includes fishes (Luciobarbus sp., Barbus sp., Luciobarbus vel...

Fossil amphibians and reptiles from the Neogene locality of Maramena (Greece), the most diverse European herpetofauna at the Miocene/Pliocene transition boundary

Georgalis, Georgios L. ; Villa, Andrea ; Ivanov, Martin ; Vasilyan, Davit ; Delfino, Massimo

In: Palaeontologia Electronica, 2019, p. -

We herein describe the fossil amphibians and reptiles from the Neogene (latest Miocene or earliest Pliocene; MN 13/14) locality of Maramena, in northern Greece. The herpetofauna is shown to be extremely diverse, comprising at least 30 different taxa. Amphibians include at least six urodelan (Cryptobranchidae indet., Salamandrina sp., Lissotriton sp. [Lissotriton vulgaris group], Lissotriton sp.,...

Recent glacier and lake changes in High Mountain Asia and their relation to precipitation changes

Treichler, Désirée ; Kääb, Andreas ; Salzmann, Nadine ; Xu, Chong-Yu

In: The Cryosphere, 2019, vol. 13, no. 11, p. 2977–3005

We present an updated, spatially resolved estimate of 2003–2008 glacier surface elevation changes for the entire region of High Mountain Asia (HMA) from ICESat laser altimetry data. The results reveal a diverse pattern that is caused by spatially greatly varying glacier sensitivity, in particular to precipitation availability and changes. We introduce a spatially resolved zonation where...

New data on the Miocene dormouse Simplomys García-Paredes, 2009 from the peri-alpin basins of Switzerland and Germany: palaeodiversity of a rare genus in Central Europe

Prieto, Jérôme ; Lu, Xiao-Yu ; Maridet, Olivier ; Becker, Damien ; Pirkenseer, Claudius ; Rauber, Gaëtan ; Peláez-Campomanes, Pablo

In: Palaeobiodiversity and Palaeoenvironments, 2019, vol. 99, no. 3, p. 527–543

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 middle Miocene. We review the record from the...

Rhinocerotidae from the early middle miocene locality Gračanica (Bugojno basin, Bosnia-Herzegovina)

Becker, Damien ; Tissier, Jérémy

In: Palaeobiodiversity and Palaeoenvironments, 2019, p. -

The early middle Miocene (European Land Mammal Zone MN5) locality Gračanica (Bugojno Basin, Bosnia-Herzegovina) has yielded numerous well-preserved dental remains of four Rhinocerotidae species: Brachypotherium brachypus, Lartetotherium sansaniense, Plesiaceratherium balkanicum sp. nov. and Hispanotherium cf. matritense. This rhinocerotid assemblage is typical of the Orleanian European Land ...

Revision of the planktonic foraminiferal biostratigraphy of the Voirons Flysch (Chablais Prealps, Haute-Savoie, France)

Ragusa, Jérémy ; Ospina-Ostios, Lina Maria ; Spezzaferri, Silvia ; Kindler, Pascal

In: Swiss Journal of Geosciences, 2018, vol. 111, no. 3, p. 461–473

The ages obtained from planktonic foraminiferal assemblages retrieved from two exposures in the Gurnigel Flysch and from the re-examination of similar material gathered by previous researchers from the Voirons Flysch reveal only minor discrepancies with previous studies based on nannofossil biostratigraphy. In contrast, major divergences between this work and previous studies on the Voirons...
