When and how did the terrestrial mid-Permian mass extinction occur? Evidence from the tetrapod record of the Karoo Basin, South Africa.
A mid-Permian (Guadalupian epoch) extinction event at approximately 260 Ma has been mooted for two decades. This is based primarily on invertebrate biostratigraphy of Guadalupian-Lopingian marine carbonate platforms in southern China, which are temporally constrained by correlation to the associated Emeishan Large Igneous Province (LIP). Despite attempts to identify a similar biodiversity crisi...
متن کاملThe double mass extinction revisited: reassessing the severity, selectivity, and causes of the end-Guadalupian biotic crisis (Late Permian)
—The end-Guadalupian extinction, at the end of the Middle Permian, is thought to have been one of the largest biotic crises in the Phanerozoic. Previous estimates suggest that the crisis eliminated 58% of marine invertebrate genera during the Capitanian stage and that its selectivity helped the Modern evolutionary fauna become more diverse than the Paleozoic fauna before the end-Permian mass ex...
متن کاملthe crisis of identity in jhumpa lahiris fiction: interpreter of maladies and the namesake
شکل گیری هویت(identity) مقوله مهمی در ادبیات پراکنده مردم(diasporan literature) می باشد. آثار جومپا لاهیری(jhumpa lahiri) ، نویسنده هندی آمریکایی، در سالهای اخیر تحسین منتقدین را به خود معطوف کرده است. وی در این آثار زندگی مهاجران و تلاش آنان برای پیدا کردن جایگاهشان در یک فرهنگ بیگانه را به تصویر کشیده است. این تجربه همواره با احساساتی نظیر دلتنگی برای گذشته، بیگانگی و دوری همراه است. با این ح...

متن کاملMethane Release from Igneous Intrusion of Coal during Late Permian Extinction Events
Unusually large and locally variable carbon isotope excursions coincident with mass extinctions at the end of the Permian Period (253 Ma) and Guadalupian Epoch (260 Ma) can be attributed to methane outbursts to the atmosphere. Methane has isotopic values (dC) low enough to reduce to feasible amounts the carbon required for isotopic mass balance. The duration of the carbon isotopic excursions an...
