The global stratotype sections and point (GSSP) for the base of the jurassic system at kuhjoch (Karwendel Mountains, Northern Calcareous Alps, Tyrol, Austria)
The Global Stratotype Section and Point (GSSP) defining the base of the Jurassic System Lower Jurassic Epoch and Hettangian Stage is situated at the Kuhjoch pass, Karwendel Mountains, Northern
Flourishing ocean drives the end-Permian marine mass extinction
Significance This study provides geochemical evidence that links some of the most important finds associated with the end-Permian mass extinction, including climate warming, enhanced weathering,
A nutrient control on marine anoxia during the end-Permian mass extinction
Oxygen deprivation and hydrogen sulfide toxicity are considered potent kill mechanisms during the mass extinction just before the Permian–Triassic boundary (~251.9 million years ago). However, the
High-resolution stratigraphy of the Changhsingian (Late Permian) successions of NW Iran and the Transcaucasus based on lithological features, conodonts and ammonoids
Abstract. The Permian–Triassic boundary sections in north-western Iran belong to the most complete successions, in which the largest mass extinction event in the history of the Earth can be studied.
The ammonoids from the Late Permian Paratirolites Limestone of Julfa (East Azerbaijan, Iran)
The Changhsingian Paratirolites Limestone is the most diverse assemblage known from the critical interval before the end-Permian mass extinction, and 20 new species are described.
Interpreting the Carbon Isotope Record of Mass Extinctions
Mass extinctions are global-scale environmental crises marked by the loss of numerous species from all habitats. They often coincide with rapid changes in the stable carbon isotope ratios (13C/12C)
