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...

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...

A new species of the large-headed coastal marine turtle Solnhofia (Testudinata, Thalassochelydia) from the Late Jurassic of NW Switzerland

Anquetin, Jérémy ; Püntener, Christian

In: PeerJ, 2020, vol. 8, p. e9931

Background: The large-headed turtle Solnhofia parsonsi is known by a handful of specimens from the Late Jurassic of Germany and Switzerland (maybe also France). Solnhofia parsonsi is traditionally regarded as a “eurysternid” Thalassochelydia, a group of small to medium sized, mostly lagoonal or marginal turtles found almost exclusively in the Late Jurassic of Europe. More recently,...

3D model related to the publication: A new species of the large-headed coastal marine turtle Solnhofia (Testudinata, Thalassochelydia) from the Late Jurassic of NW Switzerland

Anquetin, Jérémy ; Püntener, Christian

In: MorphoMuseuM, 2020, vol. 6, no. 4, p. e118

This contribution contains the 3D surface model of the holotype cranium of the Late Jurassic thalassochelydian turtle Solnhofia brachyrhyncha described and figured in the publication of Anquetin and Püntener (2020).

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)....

New material of “Eurysternidae” (Thalassochelydia, Pan-Cryptodira) from the Kimmeridgian of the Swiss Jura Mountains

Püntener, Christian ; Anquetin, Jérémy ; Billon-Bruyat, Jean-Paul

In: Palaeovertebrata, 2020, vol. 43, no. 1, p. e2

The region of Porrentruy (Swiss Jura Mountains) is known for its rich and diverse assemblage of Late Jurassic coastal marine turtles (Thalassochelydia). Dominated by the “Plesiochelyidae”, this assemblage also includes representatives of the two other thalassochelydian groups, the “Thalassemydidae” and “Eurysternidae.” In this study, we present new shell-based material from Porrentruy...

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...
