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: This study presents extensive major and trace element data for the Permian-Triassic boundary at Meishan, China, revealing changes in carbonate lithology, siliciclastic input, diagenesis, and redox conditions. The trace element patterns suggest variations in provenance and weathering processes, with anomalous behavior noted for Ba, Zr, and Zn. Rare earth elements are controlled by the siliciclastic fraction, and Ce and Eu anomalies are not reliable indicators of the redox environment at Meishan.

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: 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: Conodonts from Permian-Triassic Boundary (P-TB) beds have been extensively studied, with some species surviving the mass extinction and becoming cosmopolitan in the earliest Triassic. This study focuses on the understudied Ellisonidae from South China and finds the common presence of Merrilina (M.) spp. A representative species, M. ultima, previously considered a cool-water species, is found in warm, shallow platform settings in the earliest Triassic. It is suggested that Merrillina spp. were cosmopolitan taxa preferring surface-water habitats, rather than being restricted to cool waters.

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: This study presents integrated conodont biostratigraphy and carbon isotope analysis of the Permian-Triassic boundary (PTB) beds and Lower Triassic succession in the Baoshan block. The dominant conodont faunas in the dolomitized Hewanjie Formation are Hindeodus and Isarcicella species, along with Eurygnathodus and the Ellisoniidae. The conodont zones and carbon isotope profile are consistent with those from other well-documented sections worldwide. The study also indicates a shallow water-depth based on conodont biofacies analysis.

Summary: In terrestrial settings, the Permo-Triassic mass extinction is commonly associated with changes in sedimentological and climatic conditions. However, a study of North China's terrestrial strata revealed little substantial sedimentological change during this extinction event. The crisis level occurred in the upper Sunjiagou Formation, while a major sedimentological change happened slightly higher, within the lowest Triassic. Despite earlier claims, there was no abrupt transition in fluvial styles around the Permo-Triassic mass extinction.

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: This study examines the characteristics and formation mechanisms of deeper-water carbonates in the early Triassic through observations and interpretations of seven carbonate sections in southern China and southern Tibet. The results indicate that the deeper-water carbonates formed under anoxic conditions and were influenced by microbial activities.

Summary: This paper reports on the age of volcanic tuffs found in the Permian-Triassic deep-water sediments in the Susong area, Anhui Province. The dating results indicate that the upper and lower tuffs are 251.3 Ma and 252.3 Ma, respectively. The study of the volcanic tuffs suggests that they originated from felsic volcanism in a continental arc background, with materials from the remelting of Paleoproterozoic-Mesoproterozoic continental crust playing a role in the formation of the new crust during the collision between the South China and North China blocks.

Summary: By examining the marine Permian-Triassic reference section in Meishan, China, researchers identified molecular biomarkers of Gigantopteris, a distinctive Permian plant, providing evidence of synchronous extinction between terrestrial and marine organisms. The study also revealed a parallel reduction in lignin phenols, indicating that aridity-driven extinction may have affected the entire wetland flora in the region.

Summary: The study suggests that regional volcanic activity in the South China craton was influenced by the Siberian Traps large igneous province magmatism, possibly contributing to major biotic and environmental stresses associated with the Permian-Triassic boundary mass extinction, with four distinct mercury enrichment intervals identified. Evidence of strong volcanism in the Tethyan region is found to have started about 2 million years before the latest Permian mass extinction event.

Summary: The study shows that from the late Permian to the Middle Triassic period, global ichnodiversity and ichnodisparity levels remained stable until the Griesbachian, followed by a sharp decline. The dominance of shallow-tier trace fossils in the Griesbachian is interpreted as unusual compared to other periods.

Summary: This study identified volcano-sedimentary microfacies and facies associations in the Carboniferous-Permian sections of the southern BOC, shedding light on the tectonic and paleogeographic evolution of the region. The findings propose a succession of paleogeographic reconstructions for the BOC during the Carboniferous-Permian period, revealing the composition of the Paleo-Asian Ocean and its evolution.

Summary: This study reveals the geological ages of the brachiopod fauna in the Taungnyo Group in the Zwekabin Range of eastern Myanmar, and suggests that the Cisuralian brachiopod faunas in the Sibumasu Block should be divided into two separate assemblages, a cold-water fauna in the Sakmarian period and a biogeographically mixed fauna in the late Kungurian period.

Summary: Research on the global distribution of living brachiopods and the proposal of a global bioregionalization framework highlighted the driving factors of large-scale ocean gyres, climatic zonation, and geohistorical factors. At a regional scale, faunal composition, diversity, and biogeographical differentiation are mainly controlled by seawater temperature variation, regional ocean currents, and coastal upwelling systems.

Summary: Research in the southern Beishan Orogenic Collage in northwest China shows that the Carboniferous-Permian strata were formed by the closure of a branch of the Paleo-Asian Ocean and the subsequent development of a continental rift basin. The stratigraphy indicates a transition from marine to continental environments, with source areas composed of Precambrian and early Paleozoic rocks.
