Summary: This study examines palynological successions from the late Permian to the Early Triassic in southwestern China and identifies four distinct palynofloral assemblages. The results suggest that the Permian-Triassic mass extinction had a significant impact on terrestrial vegetation in southwestern China. The findings support the hypothesis that the extinction process of terrestrial vegetation was a two-staged and longer-duration event.

Summary: During the Permian-Triassic mass extinction, the deep-water euxinic conditions in the southern Panthalassa Ocean coincided with enhanced volcanic activity. While the global ocean experienced extreme stress on marine life, the recovery of radiolarian populations in the southern surface waters was quicker than in the northern Panthalassa by several million years.

Summary: Joachimski et al. conducted geochemical investigations on seawater temperature changes across the Permian-Triassic Boundary (PTB). However, due to an incorrect biochronology, their reported temperature changes showed discrepancies compared to the global stratotype section and point.

Summary: The study explores the impact of Permian-Triassic volcanism in Siberia on the end-Permian mass extinction, mainly through the release of CO2 from the interaction of coal with intrusions. The distribution of sills within coal-bearing successions in Tunguska Basin minimally influences the metamorphic grade of the coals, and explosion pipes delivering CO2 into the atmosphere likely formed after the extinction event.

Summary: Despite the extensive use of sulphur isotope ratios (delta S-34) for understanding ancient biogeochemical cycles, this study focuses on generating an 80 million-year Permian-Triassic delta S-34(evap) curve and incorporating it into a sulphur isotope box model. The model reveals three significant pyrite burial events in the Triassic and predicts a substantial increase in pyrite burial across the end-Permian mass extinction, possibly driven by Siberian Traps volcanism.

Summary: The usefulness of taxonomy in palaeoenvironmental analysis depends on the accurate identification of taxa, which can be challenging in cases where distinguishing between taxa is difficult. This study focuses on ostracods from the Permian-Triassic boundary in south China, which are dominated by the Family Bairdiidae, posing taxonomic challenges. The presence of ostracods in microbialites after a mass extinction event has led to the hypothesis that microbialites served as refuges, but this is still debated.

Summary: In this paper, the petrographic and geochemical characteristics of anomalous sediments in the Permian-Triassic transitional interval in Kangjiaping section, South China, are described in detail. The study also reconstructs the marine environment after the end-Permian mass extinction (EPME). The results show enhanced continental margin weathering and decreased oxygen content in shallow seawater after the EPME. Additionally, the study identifies the role of periodic relative sea-level fluctuation and arid-humid climate alternations in the evolution and repeat stacking of various microfacies in the Kangjiaping section.

Summary: This article examines the end Permian to Middle Triassic interval, which witnessed a significant marine mass extinction and delayed recovery. The focus is on Triassic marine sediments in South China, providing unique documentation of the collapse and recovery of marine ecosystems. Several papers analyze different fossils and their ecological significance, while others study biostratigraphy, reconstruct paleoenvironments, and link records to volcanic eruptions.

Summary: Research in the southern Karoo Basin of South Africa from the Late Permian to the Middle Triassic shows evidence of at least four atmospheric carbon dioxide spikes coinciding with extinctions on land and at sea. These extinctions correlate with extreme greenhouse spikes of carbon dioxide and transient episodes of warmer and more humid climate, causing respiratory distress for vertebrates and wetland plants. This provides worst-case scenarios for modern global climate change.

Summary: This study reviews the changes in plant species richness and abundance in South China from the End Permian to Middle Triassic, and examines the co-evolutionary relationship between plants and the environment during this critical period. The study identified four phases of plant evolution, with the End Permian Plant Crisis being a significant event that marked a decline in species richness and plant abundance.

Summary: The study presents high-resolution organic carbon isotope, Hg concentration, and Hg isotope curves at the PTB sections in India and China. The Hg/TOC spikes observed coincide with major environmental and carbon isotope changes. Analysis of redox-sensitive elements reveals variations in Hg/TOC spikes under different paleoredox conditions. The study highlights the significance of Hg/TOC ratios as a paleoenvironmental proxy and a tool for stratigraphic correlation.

Summary: Research analyzing Cr isotopes in marine rocks in southern China revealed changes in Cr isotope compositions during the late Permian, possibly related to oceanic anoxia. The negative excursion values following the extinction horizon may indicate the expansion of oceanic anoxia, while persistent negative values in the Early Triassic suggest a prolonged recovery period for the ocean.

Summary: The Dolomites is a significant region for studying the evolution of shallow-marine ecosystems during the end-Permian mass extinction. By using strontium isotope stratigraphy, the correlation between the Dolomites and the Meishan section can be established, contributing to the understanding of the biological crisis that occurred.

Summary: The recovery of lacustrine ecosystem in the Ordos basin during the late Middle Triassic after the Permian/Triassic mass extinction was facilitated by the high primary productivity indicated in the black organic-matter-rich shales of the Ladinian. Furthermore, analyses suggest a transition from dysoxic to oxic conditions in the water columns of the lake, potentially promoting the recovery of lacustrine biota following the PTME.

Summary: For the first time, the impact of the late Devonian Hangenberg Event on ostracods is quantified using newly acquired data from the Blue Snake section in Guizhou Province, South China. The study revealed a significant drop in specific diversity and major changes in taxonomic composition during the Hangenberg Event. The research also indicates a shift in the environment from a near-shore shallow condition to a deeper and more open offshore setting.

Summary: The study of ostracods in the Aras Valley section of northwest Iran revealed a significant turnover in species composition during the end-Permian mass extinction event, from a low-diversity Fabalicypris-dominated community to a more diverse Bairdiacypris-dominated community. This turnover coincided with a significant temperature increase and suggests that environmental changes, such as thermal stress, may have influenced ostracod assemblages prior to the extinction event.
