Science Advances|Decoupled taxonomic and ecological recoveries from the Permo-Triassic extinction

近日，美国科学杂志子刊《Science Advances》刊出了我校地学院和生环国重宋海军教授团队的研究成果——Decoupled taxonomic and ecological recoveries from the Permo-Triassic extinction。论文第一作者和通讯作者为宋海军。2.52亿年前的二叠纪-三叠纪之交，发生了显生宙最大的一次生物灭绝事件。这次灾难事件在不到10万年的时间里，灭绝了90%以上的海洋物种。在大灭绝之后的长达5百万年的早三叠世，生物多样性下降到极低的水...

GSA Bulletin|Rapid biotic rebound during the late Griesbachian indicates heterogeneous recovery patterns after the Permian-Triassic mass extinction

AbstractNew fossil data from two Early Triassic (Griesbachian to Dienerian) sections from South China show unusually high levels of both benthic and nektonic taxonomic richness occurring in the late Griesbachian. In total, 68 species (including 26 newly originated species) representing mollusks, brachiopods, foraminifers, conodonts, ostracods, and echinoderms occur in the late Griesbachian, ind...

Nature Communications|The onset of widespread marine red beds and the evolution of ferruginous oceans

AbstractBanded iron formations were a prevalent feature of marine sedimentation ~3.8–1.8 billion years ago and they provide key evidence for ferruginous oceans. The disappearance of banded iron formations at ~1.8 billion years ago was traditionally taken as evidence for the demise of ferruginous oceans, but recent geochemical studies show that ferruginous conditions persisted throughout the la...

Geology|Uranium and carbon isotopes document global-ocean redox-productivity relationships linked to cooling during the Frasnian-Famennian mass extinction

AbstractThe cause of the Frasnian-Famennian boundary (FFB) biotic crisis, one of the “Big Five” Phanerozoic mass extinctions, remains poorly understood. Here, we generated a high-resolution uranium-isotope profile (δ238U) for a marine carbonate section at Baisha, South China, in order to document secular variation in mean global-ocean redox conditions and to compare its relationship to coeva...
