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...

Fish, amphibian and reptilian assemblage from the middle Miocene locality Gračanica—Bugojno palaeolake, Bosnia and Herzegovina

Vasilyan, Davit

In: Palaeobiodiversity and Palaeoenvironments, 2020, vol. 100, no. 2, p. 437–455

This paper presents the first fossil fish, amphibian and reptilian fauna from Bosnia and Herzegovina Dinarides. The fauna of ectothermic vertebrates of the Bugojno palaeolake, dated to 15.2–14.0 Ma, composes of killifishes (Cyprinodontiformes indet.), a barb (Barbini indet. (aff. Barbus), a crocodile newt (Chelotriton sp.), a painted frog (Latonia sp.) and a crocodile (Alligatoroidea indet....

Palynological study of carbonated mounds during the holocene along the atlantic and mediterranean moroccan margins

Rachid, Jihad ; Hssaida, Touria ; Hamoumi, Naima ; Terhzaz, Loubna ; Spezzaferri, Silvia ; Frank, Norbert ; Daghor, Lamia

In: Review of Palaeobotany and Palynology, 2020, vol. 278, p. 104213

A palynological study of carbonate mounds of Atlantic and Mediterranean Moroccan margins was conducted on sediment boxcores MD13-3441, MD13-3456, MD13-3461, MD13-3465, MD13-3468 collected during the oceanographic cruise MD 194/Eurofleet - GATEWAY, which took place on June 2013.The organic remaining revealed a dominance of dinoflagellate cysts over the continental fraction, which showed very...

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...

Fossil amphibians and reptiles from the Neogene locality of Maramena (Greece), the most diverse European herpetofauna at the Miocene/Pliocene transition boundary

Georgalis, Georgios L. ; Villa, Andrea ; Ivanov, Martin ; Vasilyan, Davit ; Delfino, Massimo

In: Palaeontologia Electronica, 2019, p. -

We herein describe the fossil amphibians and reptiles from the Neogene (latest Miocene or earliest Pliocene; MN 13/14) locality of Maramena, in northern Greece. The herpetofauna is shown to be extremely diverse, comprising at least 30 different taxa. Amphibians include at least six urodelan (Cryptobranchidae indet., Salamandrina sp., Lissotriton sp. [Lissotriton vulgaris group], Lissotriton sp.,...

Possible species-flock scenario for the evolution of the cyprinid genus Capoeta (Cypriniformes: Cyprinidae) within late Neogene lake systems of the Armenian Highland

Ayvazyan, Anna ; Vasilyan, Davit ; Böhme, Madelaine

In: PLOS ONE, 2019, vol. 14, no. 5, p. e0215543

We studied 4 Ma old isolated pharyngeal teeth from lake sediments of Çevirme (Tekman Palaeolake, Erzurum Province). Based on shape characters defined for 3D models of modern species, we found that the Pliocene lake constitutes sympatric occurrence of four Capoeta species (C. cf. umbla, C. cf. baliki, C. cf. sieboldi and C. sp. sevangi/capoeta), whose modern relatives belong to a monophyletic...

Biochronological and palaeobiogeographical significance of the earliest Miocene mammal fauna from Northern Vietnam

Antoine, Pierre-Olivier ; Made, Jan van der ; Métais, Grégoire ; Phuc, Laq The ; Quan, Quý Tr??ng ; Schneider, Simon ; Tran, Dang Ngoc ; Vasilyan, Davit ; Viet, Luong The ; Böhme, Madelaine

In: Palaeobiodiversity and Palaeoenvironments, 2018, vol. 98, no. 2, p. 287–313

Current scientific knowledge of Tertiary fossils from south of the Ailao Shan-Red River shear zone is extremely poor, in sharp contrast with the situation nowadays, as the area of Laos and Vietnam is regarded as a global hotspot of biodiversity. In this context, the few localities that yielded fossil assemblages are of first importance for the understanding of Cenozoic palaeobiogeography and...

Carbonate mounds of the Moroccan Mediterranean margin: Facies and environmental controls

Terhzaz, Loubna ; Hamoumi, Naima ; Spezzaferri, Silvia ; El Lotfi, Mostapha ; Henriet, Jean-Pierre

In: Comptes Rendus Geoscience, 2018, vol. 350, no. 5, p. 212–221

Sedimentological and geochemical studies of boxcores from the Brittlestar Ridge I and Cabliers carbonate mounds, along the Moroccan Mediterranean margin, show that sediments are composed of cold water scleratian corals and micritic mud, muddy micrite or muddy allochem limestone matrix, outlining seven different facies that can be attributed to “cluster reefs”. The mixed...

The last amphisbaenian (Squamata) from continental Eastern Europe

Georgalis, Georgios L. ; Villa, Andrea ; Delfino, Massimo

In: Annales de Paléontologie, 2018, vol. 104, no. 2, p. 155–159

The fossil record of amphisbaenians in Europe has recently been augmented through the description of new finds across the continent. It has been suggested that the post- Miocene range of amphisbaenians followed a progressive southward constriction that ultimately lead to their extant disjunct distribution. We herein describe amphisbaenian vertebral material from the Pliocene of northern...
