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...

Global biogeographic synthesis and priority conservation regions of the relict tree family Juglandaceae

Song, Yi‐Gang ; Fragnière, Yann ; Meng, Hong‐Hu ; Li, Ying ; Bétrisey, Sébastien ; Corrales, Adriana ; Manchester, Steven ; Deng, Min ; Jasińska, Anna K. ; Văn Sâm, Hoàng ; Kozlowski, Gregor

In: Journal of Biogeography, 2020, vol. 47, no. 3, p. 643–657

Aim To establish a complete database of Juglandaceae at a spatiotemporal scale and develop a phylogeographic framework with which to elucidate the distributional patterns, diversity patterns, origins, evolution, and conservation priority regions of this family. Location Worldwide. Taxon Walnut family (Juglandaceae). Methods Data on the distribution of all the extant and fossil species of...

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...

A new species of Palaeopython (Serpentes) and other extinct squamates from the Eocene of Dielsdorf (Zurich, Switzerland)

Georgalis, Georgios L. ; Scheyer, Torsten M.

In: Swiss Journal of Geosciences, 2019, vol. 112, no. 2, p. 383–417

The lizard and snake fauna from the late middle–late Eocene (MP 16–MP 20) of Dielsdorf, near Zurich, Switzerland, is described comprehensively in this paper. Detailed comparisons of the Dielsdorf material with other extinct taxa allow us to establish a new species of the large “booid” genus Palaeopython, i.e., Palaeopython helveticus sp. nov., characterized by a unique combination of...

A new alligatoroid from the Eocene of Vietnam highlights an extinct Asian clade independent from extant Alligator sinensis

Massonne, Tobias ; Vasilyan, Davit ; Rabi, Márton ; Böhme, Madelaine

In: PeerJ, 2019, vol. 7, p. e7562

During systematic paleontological surveys in the Na Duong Basin in North Vietnam between 2009 and 2012, well-preserved fossilized cranial and postcranial remains belonging to at least 29 individuals of a middle to late Eocene (late Bartonian to Priabonian age (39–35 Ma)) alligatoroid were collected. Comparative anatomical study of the material warrants the diagnosis of a new taxon,...

Ancient mitogenomics clarifies radiation of extinct Mascarene giant tortoises ( Cylindraspis spp.)

Kehlmaier, Christian ; Graciá, Eva ; Campbell, Patrick D. ; Hofmeyr, Margaretha D. ; Schweiger, Silke ; Martínez-Silvestre, Albert ; Joyce, Walter G. ; Fritz, Uwe

In: Scientific Reports, 2019, vol. 9, no. 1, p. 1-7

The five extinct giant tortoises of the genus Cylindraspis belong to the most iconic species of the enigmatic fauna of the Mascarene Islands that went largely extinct after the discovery of the islands. To resolve the phylogeny and biogeography of Cylindraspis, we analysed a data set of 45 mitogenomes that includes all lineages of extant tortoises and eight near-complete sequences of all...

New paroxyclaenid mammals from the early Eocene of the Paris Basin (France) shed light on the origin and evolution of these endemic European cimolestans

Solé, Floréal ; Plateau, Olivia ; Le Verger, Kévin ; Phélizon, Alain

In: Journal of Systematic Palaeontology, 2019, vol. 17, no. 20, p. 1711–1743

We present new species of an enigmatic family of mammals, which is endemic to Europe, the Paroxyclaenidae: Merialus bruneti sp. nov., Fratrodon tresvauxi gen. et sp. nov., Paraspaniella gunnelli gen. et sp. nov., and Sororodon tresvauxae gen. et sp. nov. The fossils described come from six localities of the Ypresian of the Paris Basin (France): Pourcy (MP7), Mutigny, Avenay, Condé-en-Brie...

Comparative analysis of the shape and size of the middle ear cavity of turtles reveals no correlation with habitat ecology

Foth, Christian ; Evers, Serjoscha W. ; Joyce, Walter G. ; Volpato, Virginie S. ; Benson, Roger B. J.

In: Journal of Anatomy, 2019, no. 0, p. -

The middle ear of turtles differs from other reptiles in being separated into two distinct compartments. Several ideas have been proposed as to why the middle ear is compartmentalized in turtles, most suggesting a relationship with underwater hearing. Extant turtle species span fully marine to strictly terrestrial habitats, and ecomorphological hypotheses of turtle hearing predict that this...

A new testudinoid turtle from the middle to late Eocene of Vietnam

Garbin, Rafaella C. ; Böhme, Madelaine ; Joyce, Walter G.

In: PeerJ, 2019, vol. 7, p. e6280

Testudinoidea is a major clade of turtles that has colonized different ecological environments across the globe throughout the Tertiary. Aquatic testudinoids have a particularly rich fossil record in the Tertiary of the northern hemisphere, but little is known about the evolutionary history of the group, as the phylogenetic relationships of most fossils have not been established with...
