A new glirid-like cricetid from the lower Oligocene of Southern China

Lu, Xiao-Yu ; Ni, Xijun ; Maridet, Olivier

In: Journal of Vertebrate Paleontology, 2021, p. e1917587

Here we report a new cricetid s.l., Caecocricetodon yani, gen. et sp. nov., discovered in the early Oligocene of the Caijiachong Formation in Yunnan Province, China. The new cricetid differs from all known cricetids or stem muroids by its particular molar pattern displaying numerous crests and spurs. Our phylogenetic analysis based on a matrix including 42 taxa and 72 characters indicates...

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...

The record of Deinotheriidae from the Miocene of the Swiss Jura Mountains (Jura Canton, Switzerland)

Gagliardi, Fanny ; Maridet, Olivier ; Becker, Damien

In: bioRxiv, 2021, p. 244061

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 species, Deinotherium levius, from the locality of...

The Eomyidae in Asia: Biogeography, diversity and dispersals

Kimura, Yuri ; Casanovas-Vilar, Isaac ; Maridet, Olivier ; Kalthoff, Daniela C. ; Mörs, Thomas ; Tomida, Yukimitsu

In: Fossil Imprint, 2020, vol. 76, no. 1, p. 181-200

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 within 14 genera were reported from Asia,...

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...

Aubenas-les-Alpes (S-E France). Part III – Last and final part of the mammalian assemblage with some comments on the palaeoenvironment and palaeobiogeography = Aubenas-les-Alpes (S-E France). Part III – Dernière partie de l’assemblage mammalien avec quelques commentaires sur le paléoenvironnement et la paléobiogéographie

Maridet, Olivier ; Hugueney, Marguerite ; Costeur, Loïc

In: Annales de Paléontologie, 2019, vol. 105, no. 2, p. 139–153

The study of the new material from Aubenas-les-Alpes makes it possible to add to the faunal list taxa hitherto unknown in this locality (Neurogymnurus cayluxi, Issiodoromys minor, Eomys minor, Pseudocricetodon cf. hausi, Pseudocricetodon aff. philippi). New specimens of the shrew Srinitium marteli increase our knowledge of this rare insectivore. The characteristics of the theridomorph I....

Early Agenian rhinocerotids from Wischberg (Canton Bern, Switzerland) and clarification of the systematics of the genus Diaceratherium

Jame​, Claire ; Tissier​​, Jérémy ; Maridet, Olivier ; Becker, Damien

In: PeerJ, 2019, vol. 7, p. e7517

Background: Wischberg is a Swiss locality in Bern Canton which has yielded numerous vertebrates remains from the earliest Miocene (= MN1). It has a very rich faunal diversity, one of the richest in Switzerland for this age. Among all the mammals reported in the original faunal list 70 years ago, three rhinocerotid species were identified. The material consists of two fragmentary skulls,...

New data on Amynodontidae (Mammalia, Perissodactyla) from Eastern Europe: Phylogenetic and palaeobiogeographic implications around the Eocene-Oligocene transition

Tissier, Jérémy ; Becker, Damien ; Codrea, Vlad ; Costeur, Loïc ; Fărcaş, Cristina ; Solomon, Alexandru ; Venczel, Marton ; Maridet, Olivier

In: PLOS ONE, 2018, vol. 13, no. 4, p. e0193774

Amynodontidae is a family of Rhinocerotoidea (Mammalia, Perissodactyla) known from the late Early Eocene to the latest Oligocene, in North America and Eurasia. European Amynodontidae 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 extinctions and dispersal-generated...

A new species of Argyromys (Rodentia, Mammalia) from the oligocene of the valley of lakes (Mongolia): its importance for palaeobiogeographical homogeneity across Mongolia, China and Kazakhstan

López-Guerrero, Paloma ; Maridet, Olivier ; Zhang, Zhaoqun ; Daxner-Höck, Gudrun

In: PLOS ONE, 2017, vol. 12, no. 3, p. e0172733

We describe a new species of Rodentia (Mammalia), Argyromys cicigei sp. nov. from Toglorhoi (fossil bed TGW-A/2a) in Mongolia and Ulantatal (fossil beds UTL 1 and UTL 7) in China. Its tooth morphology differs from the type species Argyromys aralensis from Akespe in Kazakhstan by smaller size and simpler structures. Argyromys has been assigned in different families of Muroidea, such as...
