“…By the beginning of the Triassic, Pangaea had fully aggregated, and the late Permian green‐house climate had attained hot‐house status (Preto et al, 2010). The humidity of the climate oscillated, with monsoonal systems established by the end of the interval (Preto et al, 2010), particularly after the Carnian Pluvial Event (CPE; ~233 Ma), which was a major period of biological turnover associated with exceptional global rainfall (Dal Corso et al, 2020; Dal Corso, Mills, et al, 2022; Simms & Ruffell, 2018).

Recent progress in beetle palaeontology has incited us to re‐address the evolutionary history of the group. The Permian †Tshekardocoleidae had elytra that covered the posterior body in a loose tent‐like manner. The formation of elytral epipleura and a tight fit of elytra and abdomen were important evolutionary transformations in the Middle Permian, resulting in a tightly enclosed subelytral space. Permian families were likely associated with dead wood of gymnospermous trees. The end‐Permian extinction event resulted in a turnover in the composition of beetle faunas, especially a decline of large‐bodied wood‐associated forms. Adephaga and Myxophaga underwent a first wave of diversification in the Triassic. Polyphaga are very rare in this period. The first wave of diversification of this suborder occurs in the Jurassic, with fossils of Elateriformia, Staphyliniformia and Cucujiformia. The Cretaceous fossil record has been tremendously enriched by the discovery of amber inclusions. Numerous fossils represent all major polyphagan lineages and also the remaining suborders. Improved analytical methods for documenting and placing extinct taxa are discussed. Different factors have played a role in the diversification of beetles. The enormous number of species associated with flowering plants, and timing and patterns of diversification in phytophagous lineages indicate that the angiosperm radiation played a major role in beetle macroevolution. Moreover, the evolution of intimate partnerships with symbionts and the acquisition of novel genes—obtained from fungi and bacteria via horizontal gene transfers—facilitated the use of plant material as a food source and were key innovations in the diversification of plant‐feeding beetles.

“…Following cessation of the volcanism, the level of atmospheric pCO2 gradually decreases over a period of >10 Myr. This timescale is relatively long compared with the perturbations caused by LIP eruptions during the Phanerozoic, which typically cease within several million years 29,[41][42][43][44][45][46][47][48][49][50][51][52] . This difference could be attributed to the low terrestrial weatherability during the Archean, i.e., the absence of land plants and small continental areas diminished the continental weathering efficiency 53,54 .…”

The Archean Earth was characterized by a persistent weakly reducing atmosphere, while accumulated geological records suggest occurrence of transient atmospheric oxygenation events—whiff of oxygen—during the late Archean, the precise nature and causes of which remain elusive. We used a biogeochemical model to propose the eruption of large igneous provinces (LIPs) as a plausible mechanistic explanation for the transient oxygenation events in the late Archean atmosphere. Here we show that biogeochemical dynamics induced by LIP eruptions could have caused transient increase in the level of atmospheric oxygen (O2) for more than several million years. Notably, continental growth during the late Archean would have mitigated the conditions for transient oxygenation, suggesting that the late Archean Earth system approached a tipping point for permanent oxidation of the atmosphere. The late Archean atmosphere might have evolved dynamically through interactions with the ocean and the biosphere, modified by LIP eruptions.

“…Interestingly, we see no evidence for a substantial change in δ 34 S evap during the Carnian Pluvial Event (CPE), potentially suggesting the environmental changes during the CPE had little impact on the global sulphur cycle. This is of interest, as the CPE is associated with major carbon cycle perturbations, the emplacement of the Wrangellian LIP (large igneous province) and a mass extinction event (followed by biotic radiation) 26 , 27 . It is thus intriguing that our δ 34 S evap record maintains relative stability across this time interval.…”

Despite the extensive use of sulphur isotope ratios (δ34S) for understanding ancient biogeochemical cycles, many studies focus on specific time-points of interest, such as the end-Permian mass extinction (EPME). We have generated an 80 million-year Permian–Triassic δ34Sevap curve from the Staithes S-20 borehole, Yorkshire, England. The Staithes δ34Sevap record replicates the major features of the global curve, while confirming a new excursion at the Olenekian/Anisian boundary at ~ 247 million years ago. We incorporate the resultant δ34Sevap curve into a sulphur isotope box model. Our modelling approach reveals three significant pyrite burial events (i.e. PBEs) in the Triassic. In particular, it predicts a significant biogeochemical response across the EPME, resulting in a substantial increase in pyrite burial, possibly driven by Siberian Traps volcanism. Our model suggests that after ~ 10 million years pyrite burial achieves relative long-term stability until the latest Triassic.
