“…The main extinction phase is considered to have occurred shortly before the Permian–Triassic boundary and to have been short-lived (60 kyrs) 2 . However, some marine records indicate delayed extinction in deep palaeowater depths 15 and other work suggests that a second extinction episode in the earliest Triassic followed the main kill event 16,17 .…”

Past studies of the end-Permian extinction (EPE), the largest biotic crisis of the Phanerozoic, have not resolved the timing of events in southern high-latitudes. Here we use palynology coupled with high-precision CA-ID-TIMS dating of euhedral zircons from continental sequences of the Sydney Basin, Australia, to show that the collapse of the austral Permian Glossopteris flora occurred prior to 252.3 Ma (~370 kyrs before the main marine extinction). Weathering proxies indicate that floristic changes occurred during a brief climate perturbation in a regional alluvial landscape that otherwise experienced insubstantial change in fluvial style, insignificant reorganization of the depositional surface, and no abrupt aridification. Palaeoclimate modelling suggests a moderate shift to warmer summer temperatures and amplified seasonality in temperature across the EPE, and warmer and wetter conditions for all seasons into the Early Triassic. The terrestrial EPE and a succeeding peak in Ni concentration in the Sydney Basin correlate, respectively, to the onset of the primary extrusive and intrusive phases of the Siberian Traps Large Igneous Province.

“…The onset of the main marine extinction event at 251.941 AE 0.037 Ma, now considered to have occurred shortly before the Permian-Triassic boundary (PTB) at 251.902 AE 0.024 Ma (Burgess et al, 2014), is also more complex than originally thought. Some marine records indicate a delayed extinction in deep palaeowater depths (Jiang et al, 2015) and other recent work suggests that a second extinction event in the earliest Triassic followed the main kill event (Yin et al, 2007;Song et al, 2013). Retallack et al (2011) and Retallack (2013) have gone so far as to propose repeated 'greenhouse crises' throughout the late Permian and Early Triassic that cumulatively led to the main crisis and delayed recovery from it.…”

Sedimentology of the continental end‐Permian extinction event in the Sydney Basin, eastern Australia

et al. 2020

Upper Permian to Lower Triassic coastal plain successions of the Sydney Basin in eastern Australia have been investigated in outcrop and continuous drillcores. The purpose of the investigation is to provide an assessment of palaeoenvironmental change at high southern palaeolatitudes in a continental margin context for the late Permian (Lopingian), across the end-Permian Extinction interval, and into the Early Triassic. These basins were affected by explosive volcanic eruptions during the late Permian and, to a much lesser extent, during the Early Triassic, allowing high-resolution age determination on the numerous tuff horizons. Palaeobotanical and radiogenic isotope data indicate that the end-Permian Extinction occurs at the top of the uppermost coal bed, and the Permo-Triassic boundary either within an immediately overlying mudrock succession or within a succeeding channel sandstone body, depending on locality due to lateral variation. Late Permian depositional environments were initially (during the Wuchiapingian) shallow marine and deltaic, but coastal plain fluvial environments with extensive coal-forming mires became progressively established during the early late Permian, reflected in numerous preserved coal seams. The fluvial style of coastal plain channel deposits varies geographically. However, apart from the loss of peat-forming mires, no significant long-term change in depositional style (grain size, sediment-body architecture, or sediment dispersal direction) was noted across the end-Permian Extinction (pinpointed by turnover of the palaeoflora). There is no evidence for immediate aridification across the boundary despite a loss of coal from these successions. Rather, the end-Permian Extinction marks the base of a long-term, progressive trend towards better-drained alluvial conditions into the Early Triassic. Indeed, the floral turnover was immediately followed by a flooding event in basinal depocentres, following which fluvial systems similar to those active prior to the end-Permian Extinction were re-established. The age of the floral extinction is constrained to 252.54 AE 0.08 to 252.10 AE 0.06 Ma by a suite of new Chemical Abrasion Isotope Dilution Thermal Ionization Mass Spectrometry U-Pb ages on zircon grains. Another new age indicates that the return to 30

“…The Permian-Triassic mass extinction was not a sudden event in South China, but a phase of progressive environmental deterioration, spanning a few hundred thousand years, linked to rapid global warming and the widespread development of marine anoxia (e.g. Jiang et al, 2015;Song et al, 2014). The microbialites of the Napo Platform developed on carbonate platforms during the PTB extinction and represent a simple microbial ecosystem (Wang et al, 2011).…”

“…The largest mass extinction in geological history occurred around the Permian-Triassic boundary (PTB). It has been studied for several decades and various extinction patterns (e.g., Shen et al, 2018Shen et al, , 2011Jiang et al, 2015;Wignall, 2015;Wang et al, 2014;Song et al, 2013;Yin et al, 2012) noted with numerous causes (e.g., Sun et al, 2018; Baresel et al, 2017;Ernst and Youbi, 2017;Foster et al, 2017;Grasby et al, 2016;Xiang et al, 2016;Chen Z-Q et al, 2015;Jiang et al, 2015;Song et al, 2014;Yin et al, 2014;Joachimski et al, 2012;Sun et al, 2012) proposed, but debate on the timing and nature of the crisis continues. Much of this discussion has been focused on sections in South China, notably the Global Stratotype Section and Point (GSSP) at Meishan and the auxiliary GSSP at Shangsi.…”

“…Much of this discussion has been focused on sections in South China, notably the Global Stratotype Section and Point (GSSP) at Meishan and the auxiliary GSSP at Shangsi. Many sections in the Nanpanjiang Basin area have also provided important insights into PTB events, e.g., the persistence of siliceous deposition into the Early Triassic at Gaimao (Yang et al, 2012), the occurrence of delayed extinction in the deep-water location of Bianyang (Jiang et al, 2015) and the age of post-extinction microbialite facies following a hiatus in shallow, carbonate settings (Baresel et al, 2017;Jiang et al, 2014) at the Great Bank of Guizhou (GBG).…”
