The end-Permian mass extinction brought the Palaeozoic great experiment in marine life to a close during an interval of intense climatic, tectonic and geochemical change. Improved knowledge of latest Permian faunas, coupled with recent advances in isotopic studies and biostratigraphy, have greatly enhanced our understanding of the events of 250 million years ago and have begun to provide answers to many questions about the causes of extinction. 
Comparative Earth History and Late Permian Mass Extinction
The repeated association during the late Neoproterozoic Era of large carbon-isotopic excursions, continental glaciation, and stratigraphically anomalous carbonate precipitation provides a frameworkExpand
Abrupt and Gradual Extinction Among Late Permian Land Vertebrates in the Karoo Basin, South Africa
TLDR
The vertebrate fossil data show a gradual extinction in the Upper Permian punctuated by an enhanced extinction pulse at the Permians-Triassic boundary interval, particularly among the dicynodont therapsids, coinciding with negative carbon-isotope anomalies. Expand
End-Permian catastrophe by a bolide impact: Evidence of a gigantic release of sulfur from the mantle
Our studies in southern China have revealed a remarkable sulfur and strontium isotope excursion at the end of the Permian, along with a coincident concentration of impact- metamorphosed grains andExpand
U/Pb zircon geochronology and tempo of the end-permian mass extinction
TLDR
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
RESEARCH FOCUS: Changes in productivity and oxygenation during the Permian-Triassic transition
The causes of the transition from an Early Permian cold house into an Early Triassic hothouse world have been of great interest, because this time encompasses the greatest extinction of species inExpand
Timing of mammal-like reptile extinctions across the Permian-Triassic boundary in South Africa
The rate, timing, and pattern of change in different regions and paleoenvironments are critical for distinguishing among potential causes for the Permian-Triassic (P-T) extinction. Carbon isotopicExpand
Enhanced flux of extraterrestrial 3He across the Permian–Triassic boundary
AbstractThe ca 252 Ma Permian–Triassic boundary (PTB) represents the most severe mass extinction event of the Phanerozoic, with the disappearance of ~ 80% of marine invertebrate species. Large-scaleExpand
Altered river morphology in south africa related to the permian-triassic extinction
TLDR
Evidence from correlative nonmarine strata elsewhere in the world containing fluvial Permian-Triassic boundary sections suggests that a catastrophic terrestrial die-off of vegetation was a global event, producing a marked increase in sediment yield as well as contributing to the global delta(13)C excursion across the Permians-Tri Jurassic boundary.

Insects during the time around the Permian—Triassic crisis
Dramatic changes in ancient biotas usually interpreted as ecological crises or mass extinctions are treated in many publications of every sort, and yet our notions about such events remainExpand
Impact Event at the Permian-Triassic Boundary: Evidence from Extraterrestrial Noble Gases in Fullerenes
TLDR
Fullerenes from sediments at the PTB contain trapped helium and argon with isotope ratios similar to the planetary component of carbonaceous chondrites, implying that an impact event accompanied the extinction, as was the case for the Cretaceous-Tertiary extinction event about 65 million years ago.

Conodont Survival and Low Iridium Abundances Across the Permian-Triassic Boundary in South China
TLDR
A low concentration of iridium in the boundary clay (0.002 part per billion �20 percent) and in samples immediately below and above, do not support the proposal of an extraterrestrial impact event at this boundary in China. Expand

Synchronism of the Siberian Traps and the Permian-Triassic Boundary
TLDR
The results are consistent with the hypothesis that the P-Tr extinction was caused by the Siberian basaltic flood volcanism and may have been caused by a combination of acid rain and global cooling as well as rapid and extreme changes in sea level resulting from expansion of the polar ice cap.
