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 taxonomic revision of geoemydid turtles from Siwalik-age of India and Pakistan

Garbin, Rafaella C. ; Bandyopadhyay, Saswati ; Joyce, Walter G.

In: European Journal of Taxonomy, 2020, no. 652, p. -

Neogene (Siwalik-aged) deposits from India and Pakistan have yielded many vertebrate fossils, of which most were named during the 19th century, including numerous geoemydid turtles. In contrast to many other faunal components from the Siwaliks, geoemydids have not undergone taxonomic revision for more than a century and most fossils have therefore been believed to correspond to recent taxa....

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...

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,...

Integrated bio- and cyclostratigraphy of Middle Triassic (Anisian) ramp deposits, NW Bulgaria

Ajdanlijsky, George ; Strasser, André ; Götz, Annette E.

In: Geologica Carpathica, 2019, vol. 70, no. 4, p. 325–354

A cyclostratigraphic interpretation of peritidal to shallow-marine ramp deposits of the early Middle Triassic (Anisian) Opletnya Member exposed in outcrops along the Iskar River gorge, NW Bulgaria, is presented. Based on facies trends and bounding surfaces, depositional sequences of several orders can be identified. New biostratigraphic data provide a time frame of the studied succession with...

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...

Biogeography and phylogenetic relationships of Hyrcanian wild apple using cpDNA and ITS noncoding sequences

Yousefzadeh, Hamed ; Khodadost, Ali ; Abdollahi, Hamid ; Ali, Syed Shujait ; Kozlowski, Gregor ; Bina, Hamid

In: Systematics and Biodiversity, 2019, vol. 17, no. 3, p. 295–307

The Hyrcanian forest of northern Iran is considered one of the potential centres for the evolution and domestication of the genus Malus (Rosaceae). However, the biogeography, phylogenetic position, and taxonomic status of the Hyrcanian wild apples have never been evaluated. In our study, the nucleotide sequences of the internal transcribed spacer (ITS) and the trnH-psbA intergenic spacer...
