TL;DR: Based on analyses of single, thermally annealed and chemically abraded zircons, a new high-precision U-Pb age of 251.22± 0.20 Ma is established for a volcanic ash layer within the “Kashmirites densistriatus beds” of early Smithian age (Early Triassic) from the Luolou Formation (northwestern Guangxi, South China) as discussed by the authors.
Journal ArticleDOI
Good genes and good luck: Ammonoid diversity and the end-permian mass extinction
Arnaud Brayard,Gilles Escarguel,Hugo Bucher,Claude Monnet,Thomas Brühwiler,Nicolas Goudemand,Thomas Galfetti,Jean Guex +7 more
TL;DR: Analysis of a global diversity data set of ammonoid genera covering about 106 million years centered on the Permian-Triassic boundary shows that Triassic ammonoids actually reached levels of diversity higher than in the PerMian less than 2 million years after the PTB.
Journal ArticleDOI
Climatic and biotic upheavals following the end-Permian mass extinction
Carlo Romano,Nicolas Goudemand,Torsten Vennemann,David Ware,Elke Schneebeli-Hermann,Elke Schneebeli-Hermann,Peter A. Hochuli,Peter A. Hochuli,Thomas Brühwiler,Winand Brinkmann,Hugo Bucher,Hugo Bucher +11 more
TL;DR: In this article, a temperature reconstruction shows that further biotic crises during the recovery were associated with extreme warmth in the Permian mass extinction, and the recovery from the end-Permian extinction was slow and prolonged.
Journal ArticleDOI
Transient metazoan reefs in the aftermath of the end-Permian mass extinction
Arnaud Brayard,Emmanuelle Vennin,Nicolas Olivier,Kevin G. Bylund,James F. Jenks,Daniel A. Stephen,Hugo Bucher,Richard Hofmann,Nicolas Goudemand,Gilles Escarguel +9 more
TL;DR: In this paper, the authors use field and microscopic investigations to document Early Triassic bioaccumulations and reefs from the western USA that comprise of various sponges and serpulids associated with microbialites and other eukaryotic benthic organisms.
Journal ArticleDOI
New trace fossil evidence for an early recovery signal in the aftermath of the end-Permian mass extinction
TL;DR: In this paper, a global and synchronous succession of crises and relaxation phases after the Griesbachian is proposed as an explanatory model for the recovery pattern of benthic ecosystems.
