New species, revision, and phylogeny of Ronzotherium Aymard, 1854 (Perissodactyla, Rhinocerotidae)

Tissier, Jérémy ; Antoine, Pierre-Olivier ; Becker, Damien

In: European Journal of Taxonomy, 2021, vol. 753, p. 1-80

Ronzotherium is one of the earliest Rhinocerotidae in Europe, which first appeared just after the Eocene/Oligocene transition (Grande Coupure), and became extinct at the end of the Oligocene. It is a large-sized rhinocerotid, with a special position in the phylogeny of this group, as being one of the earliest-branching true Rhinocerotidae. However, its intra-generic systematics has never been...

3D models related to the publication: New material of Epiaceratherium and a new species of Mesaceratherium clear up the phylogeny of the early Rhinocerotidae (Perissodactyla)

Tissier, Jérémy ; Antoine, Pierre-Olivier ; Becker, Damien

In: MorphoMuseuM, 2020, vol. 6, no. 3, p. e116

The present 3D Dataset contains two 3D models described in Tissier et al. (https://doi.org/10.1098/rsos.200633): the only known complete mandible of the early-branching rhinocerotoid Epiaceratherium magnum Uhlig, 1999, and a hypothetical reconstruction of the complete archetypic skull of Epiaceratherium Heissig, 1969, created by merging three cranial parts from three distinct Epiaceratherium...

New material of Epiaceratherium and a new species of Mesaceratherium clear up the phylogeny of early Rhinocerotidae (Perissodactyla)

Tissier, Jérémy ; Antoine, Pierre-Olivier ; Becker, Damien

In: Royal Society Open Science, 2020, vol. 7, no. 7, p. 200633

Reduction of the anterior dentition (i.e. incisors and canines) is a major adaptative trait of the Rhinocerotidae among Perissodactyla. However, the corresponding evolutionary sequence was lacking a robust phylogenetic frame to support it thus far. Here, we describe a new Oligocene species of Rhinocerotinae, Mesaceratherium sp. nov. from the Swiss locality of Bumbach (MP25 reference level)....

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...

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...

Trends in carbapenemase-producing Enterobacteriaceae, France, 2012 to 2014

Dortet, Laurent ; Cuzon, Gaëlle ; Ponties, V ; Nordmann, Patrice

In: Eurosurveillance, 2017, vol. 22, no. 6, p. -

In 2014, a total of 2,976 Enterobacteriaceae isolates with decreased susceptibility to carbapenems were received at the French Associated National Reference Center for Antibiotic Resistance (NRC) and were characterised for their molecular resistance mechanism to carbapenems and compared with results obtained during 2012 and 2013.The overall number of enterobacterial isolates with decreased...

Evolution of oligo-miocene Talpids (Mammalia, Talpidae) in europe: focus on the genera Myxomygale and Percymygale n. gen.

Hugueney, Marguerite ; Maridet, Olivier

In: Historical Biology, 2017, p. -

New material recovered in the Oligocene locality St-Martin-de-Castillon (Vaucluse, France; MP24) provides a better knowledge of the characteristics of the species vauclusensis in its type-locality, hitherto assigned to the genus Myxomygale (Talpinae, tribe Urotrichini). In Europe, the species assigned to Myxomygale range from Late Eocene/Early Oligocene to the end of the Middle Miocene (MN...
