Abstract Study of the Mesozoic succession Franz Josef Land (FJL) has shed new insights on stratigraphy and geological history neighboring portion Arctic. Based composition pebbles cobbles from Lower Jurassic conglomerates, we suggest that pre‐Mesozoic NE Barents Sea comprises Cambrian metasandstones intruded by Late Paleozoic granites overlain Carboniferous–Permian sedimentary deposits. U‐Pb ZH...

This paper presents structural evidence of extensional activity in Central Alborz during Mesozoic. The structural evidence of homogenous early stage stretching such as layer-parallel to oblique boudinage of Permian and Triassic rocks in various portions of the study area accompanied by extensional-fibrous fractures were followed with more advanced extensional features. These extensional structu...

Recent fieldwork has yielded new decapod crustacean material from Upper Jurassic–lowest Cretaceous bioclastic limestones at Kotouč quarry near Štramberk (Moravia, northeastern Czech Republic). Two specimens in this lot can be ascribed to the superfamily Palaeocorystoidea and represent oldest gymnopleuran crabs known date. A genus species, Moravacarcinus stramberkensis, are here erected assigned...

[1] The >300-km long, east striking Lapeiquan fault lies in the eastern Altyn Tagh range along the northern margin of the Tibetan Plateau and was interpreted as a north dipping thrust in early studies. However, our mapping shows that the fault is a south dipping normal fault juxtaposing Archean-Proterozoic gneisses beneath an early Paleozoic volcanic and sedimentary sequence. Its dip angle vari...

The Jurassic and Cretaceous sedimentary infill of the Irish Celtic Sea Basins is intimately associated with breakup supercontinent Pangea, opening Atlantic margin. Previous basin studies have constrained tectonism, uplift sediment composition, but provenance routing not received detailed consideration. Current hypotheses for suggest localized sourcing throughout Cretaceous, despite a dynamic te...

The Continental African abelisauroid theropod dinosaur fossil record from the Jurassic-Cretaceous periods is becoming increasingly better understood, and offers great insight into evolution biogeography of this long-lived group carnivores. Abelisauroidea among most familiar groups dinosaurs Gondwana, with records in South America, Australia, India Africa, along Europe. objective present study t...

Anurans (frogs and toads) are unique among land vertebrates in possessing a free-living larval stage that, parallel to adult frogs, diversified into an impressive range of ecomorphs. The tempo and mode at which tadpole morphology evolved through anuran history as well as its relationship to lineage diversification remain elusive. We used a molecular phylogenetic framework to examine patterns of...

Palynostratigraphy and palynofacies analyses are applied to identify transgressive-regressive sequences changes in paleoenvironment through the Middle Jurassic–Early Cretaceous succession of Ramså Basin on Andøya. The conglomerate, succeeding lacustrine-swamp deposits Hestberget Kullgrøfta members (Ramså Formation) overlying terrestrial marginal marine lower Bonteigen Member Formation), compris...
