The Triassic–Jurassic transition, which is here broadly defined as extending from the Late Triassic through the Early Jurassic (~237 Ma to 174 Ma), was an important interval in Earth history. The end-Triassic mass extinction (ETME), at ~201 Ma, ranks among the ‘Big Five’ Phanerozoic mass extinctions. It largely completed the shift from the ‘Paleozoic Evolutionary Fauna’ to the ‘Modern Evolutionary Fauna’ that had been initiated by the end-Permian mass extinction, and may have contributed to the ‘Mesozoic Marine Revolution’ and rise of dinosaurs to dominance in terrestrial environments. In addition, the Triassic–Jurassic transition encompasses a second-order mass extinction during the early Toarcian oceanic anoxic event (T-OAE), at ~181 Ma. The ETME was triggered by Central Atlantic Magmatic Province (CAMP) magmatism, and the T-OAE by Karoo-Ferrar Large Igneous Province (KFLIP) magmatism, both associated with the stepwise disintegration of the Pangean supercontinent. These events led to major changes in continental and marine habitats, including climatic warming, ocean acidification, and widespread watermass anoxia, that produced a cascade of lethal environmental stresses. This article undertakes a review of the ETME and T-OAE mass extinctions, the large igneous province eruptions that triggered those biotic events, and the web of environmental changes that linked them together.

三叠纪-侏罗纪过渡，这里广义地定义为从晚三叠世延伸到早侏罗世（~237 Ma 到 174 Ma），是地球历史上的一个重要时期。三叠纪末大灭绝（ETME），在~201 Ma，属于“大五”显生宙大灭绝之一。它在很大程度上完成了由二叠纪末大灭绝引发的从“古生代进化动物群”到“现代进化动物群”的转变，并可能促成了“中生代海洋革命”和恐龙崛起并在陆地上占主导地位环境。此外，三叠纪-侏罗纪过渡包括在约 181 Ma 的早期 Toarcian 海洋缺氧事件 (T-OAE) 期间的二级大规模灭绝。ETME是由中大西洋岩浆省（CAMP）岩浆活动引发的，和 Karoo-Ferrar 大火成岩省 (KFLIP) 岩浆作用的 T-OAE，两者都与 Pangean 超大陆的逐步解体有关。这些事件导致大陆和海洋栖息地发生重大变化，包括气候变暖、海洋酸化和广泛的水体缺氧，从而产生了一连串致命的环境压力。本文对 ETME 和 T-OAE 大规模灭绝、引发这些生物事件的大型火成岩省喷发以及将它们联系在一起的环境变化网络进行了回顾。这产生了一连串致命的环境压力。本文对 ETME 和 T-OAE 大规模灭绝、引发这些生物事件的大型火成岩省喷发以及将它们联系在一起的环境变化网络进行了回顾。这产生了一连串致命的环境压力。本文对 ETME 和 T-OAE 大规模灭绝、引发这些生物事件的大型火成岩省喷发以及将它们联系在一起的环境变化网络进行了回顾。
