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....

First fossil frog from Antarctica: implications for Eocene high latitude climate conditions and Gondwanan cosmopolitanism of Australobatrachia

Mörs, Thomas ; Reguero, Marcelo ; Vasilyan, Davit

In: Scientific Reports, 2020, vol. 10, p. 5051

Cenozoic ectothermic continental tetrapods (amphibians and reptiles) have not been documented previously from Antarctica, in contrast to all other continents. Here we report a fossil ilium and an ornamented skull bone that can be attributed to the Recent, South American, anuran family Calyptocephalellidae or helmeted frogs, representing the first modern amphibian found in Antarctica. The two bone...

In: Quaternary Research, 2020, vol. 93, no. 1, p. 187–203

A new fossil site in a previously unexplored part of western Madagascar (the Beanka Protected Area) has yielded remains of many recently extinct vertebrates, including giant lemurs (Babakotia radofilai, Palaeopropithecus kelyus, Pachylemur sp., and Archaeolemur edwardsi), carnivores (Cryptoprocta spelea), the aardvark-like Plesiorycteropus sp., and giant ground cuckoos (Coua). Many of these...

Learning from scientific texts: personalizing the text increases transfer performance and task involvement

Dutke, Stephan ; Grefe, Anna Christiane ; Leopold, Claudia

In: European Journal of Psychology of Education, 2016, vol. 31, no. 4, p. 499-513

In an experiment with 65 high-school students, we tested the hypothesis that personalizing learning materials would increase students’ learning performance and motivation to study the learning materials. Students studied either a 915-word standard text on the anatomy and functionality of the human eye or a personalized version of the same text in which 60 definite articles (e.g., “the...

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 is an enigmatic lizard from the Paleogene of the Phosphorites of Quercy, France that was first mentioned in the 19th century. Although it is generally believed that Filhol was the author who established this taxon, I am herein demonstrating that authorship should in fact be attributed to Zittel, a fact that also influences not only its generic nomenclature, but also its...

Eocene Western European endemic genus Thaumastosaurus: new insights into the question “Are the Ranidae known prior to the Oligocene?”

Vasilyan, Davit

In: PeerJ, 2018, vol. 6, p. e5511

Background Amphibians, due to their ecophysiological peculiarities, have a physiology dependent on environmental conditions and sensitively respond to their changes. Here, the oldest record of the genus Thaumastosaurus is described, whose fossil record known exclusively from Western Europe is discussed in the scope of the climatic changes of 33.5–40.5 Ma. Results In the present paper, the...

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...
