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...

Genetic structure of the endemic Papaver occidentale indicates survival and immigration in the Western Prealps

Pittet, Loïc ; Fragnière, Yann ; Grünig, Sandra ; Bétrisey, Sébastien ; Clément, Benoît ; Gerber, Emanuel ; Ronikier, Michał ; Kozlowski, Gregor ; Parisod, Christian

In: Alpine Botany, 2020, p. -

Climatic oscillations of the Quaternary rapidly compelled plant species to shift their geographical range. How alpine plant species responded to climate change, however, remains elusive and remnants of the cold-adapted flora that currently strive in restricted ranges as small, isolated populations have been particularly overlooked. To address the evolutionary history of such a ‘glacial...

Necrosaurus or Palaeovaranus? Appropriate nomenclature and taxonomic content of an enigmatic fossil lizard clade (Squamata) = Necrosaurus ou Palaeovaranus ? Nomenclature appropriée et contenu systématique d’un clade énigmatique de lézards fossiles (Squamata)

Georgalis, Georgios L.

In: Annales de Paléontologie, 2017, vol. 103, no. 4, p. 293–303

Necrosaurus cayluxi est un lézard énigmatique du Paléogène des Phosphorites du Quercy, France, qui a été mentionné pour la première fois au 19e siècle. Bien qu’il soit généralement admis que Filhol est l’auteur qui a établi ce taxon, je démontre ici que la paternité devrait en fait en être attribuée à Zittel, ce qui influence également non seulement la nomenclature...

Mosaicomeryx gen. nov., a ruminant mammal from the Oligocene of Europe and the significance of ‘gelocids’

Mennecart, Bastien ; Métais, Grégoire

In: Journal of Systematic Palaeontology, 2015, vol. 13, no. 7, p. 581–600

The description of new material and the reassessment of specimens previously assigned to Gelocus quercyi lead us to propose a new genus for this species, Mosaicomeryx gen. nov. Moreover, the description of a juvenile skull and other specimens of Prodremotherium elongatum, and comparison with Dremotherium, provide evidence that these two genera are not closely related as previously thought. A...
