TL;DR: High-precision geochronologic dating constrains probable causes of Earth's largest mass extinction and reveals that the extinction peak occurred just before 252.28 ± 0.08 million years ago, after a decline of 2 per mil (‰) in δ13C over 90,000 years, and coincided with a δ 13C excursion that is estimated to have lasted ≤20,000 Years.

TL;DR: This work presents a high-precision age model for the end-Permian mass extinction, which was the most severe loss of marine and terrestrial biota in the last 542 My, that allows exploration of the sequence of events at millennial to decamillenial timescales 252 Mya and establishes an accurate time point for evaluating the plausibility of trigger and kill mechanisms.

TL;DR: In this paper, high-resolution oxygen isotope records document the timing and magnitude of global warming across the Permian-Triassic boundary and suggest that the addition of isotopically light carbon to the ocean-atmosphere system by Siberian Traps volcanism and related processes resulted in higher greenhouse gas levels and global warming.

TL;DR: In this article, the authors report secular trends in bulk isotopic parameters and lipid biomarkers in a core spanning 214 m of stratigraphic section across the PTB and through the entire Changhsingian interval, revealing distinct shifts in paleoenvironmental conditions and profound changes in plankton ecology well before and following the biological extinction event.

TL;DR: A high-resolution oxygen isotope record based on 356 measurements of conodont apatite from several low latitudinal sections in South China, USA and Iran was composed in order to unravel Permian palaeotemperature and ice volume history.
