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...

Triassic–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 ...

Phanerozoic 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...

Magnitude and Duration of a Co 2 Super Greenhouse at the Triassic-jurassic Boundary

Stratigraphic transitions from the Triassic to the Jurassic (Tr-J) around 200 Ma record an abrupt extensive global collapse and slow recovery of biodiversity, the cause of which has been tied to a massive abrupt, extrinsically caused climate change (Ward et al., 2001; Hesselbo et al., 2002). The main thrust of the proposed research will be to reconstruct Tr-J paleo-atmospheric CO2, suggested to...
