Dinoflagellate cysts from the Upper Triassic (Rhaetian) strata of the Tabas Block, East - Central Iran
Rhaetian strata from the Nayband Formation of the Tabas block, East- Central Iran, were studied palynologically. The materialexamined contained moderately diverse and well-preserved dinoflagellate cyst assemblages which lead to the identification ofRhaetogonyaulax rhaetica Zone. The assigned age of this dinozone (Rhaetian) is justified by plant fossils such as Equisetitesarenaceus, Scytophyllum...

متن کاملTriassic–Jurassic boundary events: Problems, progress, possibilities
As for most geological period boundaries, the Triassic–Jurassic (T–J) transition, ∼200 million years ago, was a critical juncture in Earth history during which profound biotic and environmental changes took place. Early comparisons with the end-Cretaceous extinction and the involvement of extraterrestrial impact have now largely, although not entirely, given way to more Earthbound explanations ...
متن کاملPhanerozoic survivors: Actinopterygian evolution through the Permo‐Triassic and Triassic‐Jurassic mass extinction events
Actinopterygians (ray-finned fishes) successfully passed through four of the big five mass extinction events of the Phanerozoic, but the effects of these crises on the group are poorly understood. Many researchers have assumed that the Permo-Triassic mass extinction (PTME) and end-Triassic extinction (ETE) had little impact on actinopterygians, despite devastating many other groups. Here, two m...
متن کاملA Triassic-Jurassic window into the evolution of Lepidoptera
On the basis of an assemblage of fossilized wing scales recovered from latest Triassic and earliest Jurassic sediments from northern Germany, we provide the earliest evidence for Lepidoptera (moths and butterflies). The diverse scales confirm a (Late) Triassic radiation of lepidopteran lineages, including the divergence of the Glossata, the clade that comprises the vast multitude of extant moth...
