  author={Richard J. Twitchett and Cindy V. Looy and Richard J. Morante and Henk Visscher and Paul B. Wignall},
A newly studied Permian-Triassic (P-Tr) boundary section in Jameson Land, East Greenland, contains an abundant and well-preserved marine fauna as well as terrestrial palynomorphs. For the first time it is possible to compare the biotic crises of the marine and terrestrial realms using the same samples from the same section. The sediments record a negative excursion in δ 13 C carb values of 8‰–9‰, and in δ 13 C org values of 10‰–11‰. The presence of the conodont Hindeodus parvus, combined with… Expand
The terrestrial end-Permian mass extinction in South China
Abstract The end-Permian mass extinction reflects the most severe life crisis during the Phanerozoic and was associated with major global environmental changes. However, the consistency of the timeExpand
End-Permian terrestrial disturbance followed by the complete plant devastation, and the vegetation proto-recovery in the earliest-Triassic recorded in coastal sea sediments
Abstract The Permian−Triassic mass extinction was the most severe biotic crisis of the past 540 million years, eliminating 80–90% of species in the ocean and ~ 70% of land-based vertebrate families.Expand
Rapid demise and recovery of plant ecosystems across the end-Permian extinction event
Abstract The end-Permian extinction event was the most pronounced biotic and ecological crisis in the history of the Earth. It is assumed that over 80% of marine genera disappeared, and that thisExpand
Salinity changes and anoxia resulting from enhanced run-off during the late Permian global warming and mass extinction event
Abstract. The late Permian biotic crisis had a major impact on marine and terrestrial environments. Rising CO2 levels following Siberian Trap volcanic activity were likely responsible for expandingExpand
Refined Permian–Triassic floristic timeline reveals early collapse and delayed recovery of south polar terrestrial ecosystems
The collapse of late Permian (Lopingian) Gondwanan floras, characterized by the extinction of glossopterid gymnosperms, heralded the end of one of the most enduring and extensive biomes in Earth’sExpand
Ecosystem remodelling among vertebrates at the Permian–Triassic boundary in Russia
The nature of the event in Russia is document in a comprehensive survey of 675 specimens of amphibians and reptiles from 289 localities spanning 13 successive geological time zones in the South Urals basin, with a profound loss of genera and families and simplification of ecosystems. Expand
Delayed recovery of non-marine tetrapods after the end-Permian mass extinction tracks global carbon cycle
It is demonstrated that non-marine tetrapods were severely affected by the end-Permian mass extinction, and that these assemblages did not begin to recover until the Middle Triassic, consistent with the idea that unstable low-diversity post-extinction ecosystems were subject to boom–bust cycles.

Early Triassic terrestrial tetrapod fauna: a review
ABSTRACT The Permian-Triassic mass extinction (PTME, ca. 252 Mya) was one of the most severe biotic crises of the Phanerozoic, eliminating > 90% of marine and terrestrial species. This was followedExpand
End-Permian stratigraphic timeline applied to the timing of marine and non-marine extinctions
Abstract A latest Permian timeline (251.9 Ma) can be constructed from the perspectives of: a global nickel spike attributed to emissions from the coeval Siberian flood-basalt eruptions, theExpand
Biostratigraphic correlation and mass extinction during the Permian-Triassic transition in terrestrial-marine siliciclastic settings of South China
Abstract The Permian-Triassic boundary marks the greatest mass extinction during the Phanerozoic, which was coupled with major global environmental changes, and is known especially fromExpand


Permian-Triassic extinction: Organic δ13C evidence from British Columbia, Canada
The Permian-Triassic (P-T) extinction is documented geochemically in a marine sequence deposited in a basinal setting at Williston Lake, northeastern British Columbia, by using elemental and isotopicExpand
13C minima follow extinction events: A clue to faunal radiation
Changes in the carbon isotope composition of carbonate rocks at time-boundary zones show similar patterns in all three major boundaries: Precambrian/Cambrian, Permian/Triassic, andExpand
Palaeoenvironments and faunal recovery after the end-Permian mass extinction
Abstract Strata of the Lower Triassic Werfen Formation (Dolomites, northern Italy) record deposition in a wide range of palaeoenvironments from peritidal to outer ramp settings. This enables accurateExpand
The terminal Paleozoic fungal event: evidence of terrestrial ecosystem destabilization and collapse.
This fungal event can be considered to reflect excessive dieback of arboreous vegetation, effecting destabilization and subsequent collapse of terrestrial ecosystems with concomitant loss of standing biomass. Expand
The delayed resurgence of equatorial forests after the permian-triassic ecologic crisis.
The reconstructed pattern of vegetational change suggests that habitat restoration, migration, and evolutionary processes acted synergistically, setting the stage for successional replacement of lycopsid dominants by conifers within a period of approximately 0.5 million years. Expand
Evidence for abrupt latest Permian mass extinction of foraminifera: Results of tests for the Signor-Lipps effect
We used published biostratigraphic data on ranges of fusulinids and other foraminifera from Permian-Triassic boundary sections in the southern Alps, Italy, to test the effects of sampling and speciesExpand
The Great Paleozoic Crisis
Are you looking for an exciting book in Geology? Every textbook tells that nothing in Earth history has been more puzzling than that great wave of extinctions that swept the Earth round about 250Expand
Mass Extinctions and Their Aftermath
In this text the demise of the dinosaurs is put into the proper context of other extinction events and all proposed extinction mechanisms - climate change, meteorite impact, volcanisms - are critically assessed. Expand
δ13C depth profiles from paleosols across the Permian-Triassic boundary: Evidence for methane release
Stable carbon isotopic analyses of organic carbon (δ 13 C) in individual paleosol profiles from Permian–Triassic sequences of Antarctica reveal systematic isotopic variations with profile depth.Expand
U/Pb zircon geochronology and tempo of the end-permian mass extinction
Biostratigraphic controls from strata intercalated with ash beds below the boundary indicate that the Changhsingian pulse of the end-Permian extinction, corresponding to the disappearance of about 85 percent of marine species, lasted less than 1 million years. Expand
