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: In this article, a high-resolution stratigraphic and temporal framework is established for the Permian Period, which consists of three series (i.e., Cisuralian, Guadalupian and Lopingian in ascending order) and nine stages.

TL;DR: In this article, a high-resolution δ13Ccarb chemostratigraphic framework from latest Guadalupian to earliest Triassic time was presented, calibrated with high resolution conodont biostratigraphy and high-precision geochronology.

TL;DR: In this paper, high-resolution oxygen isotope analyses of conodont apatite from South China were used to reconstruct highresolution seawater temperature records across the Permian-Triassic boundary (PTB) intervals.

TL;DR: This paper reported a variety of marine animals symbiotic with or adhere to Burmese amber or the amber deposits, including crinoid columns, corals and oysters, and suggested that it is plausible to generally refer to the age of Burmies amber as mid-Cretaceous, and a precise age requires further biostratigraphic and chronological studies.
