二叠纪末至中三叠世（252-242 Ma）是中生代最大规模的海洋生物大灭绝和最延迟的恢复期。这些生物和环境变化的性质和机制仍不清楚。这期特刊聚焦于华南三叠纪海洋沉积物，为海洋生态系统的崩溃和恢复提供了独特的记录。六篇论文集中在早中三叠世的生物变化及其生态意义，记录了来自双壳类、海洋爬行动物、叠层动物、hybodontid牙齿、脊椎动物粪化石和其他推定化石的证据。两篇论文研究了二叠纪-三叠纪界线（PTB）和印度-奥伦尼克阶界线的牙形石生物地层。两篇论文重建了早三叠世巢湖动物群和中三叠世罗平生物群的古环境。另外两篇论文提出了新的海洋δ 13 C记录和生物标志物数据，并将其与早三叠世时期的火山爆发联系起来。这些新发现对于理解二叠纪-三叠纪边界大灭绝后生物和环境变化之间的共同进化具有重要意义。
The end Permian to Middle Triassic interval (∼252–242 Ma) witnessed the largest marine mass extinction and the most delayed recovery in the Phanerozoic. The nature and mechanism of these biotic and environmental changes remain unclear. This special issue focuses on the Triassic marine sediments in South China, which provide unique documentation of the collapse and recovery of marine ecosystems. Six papers focus on biotic changes and their ecological significance in Early and Middle Triassic times, documenting evidence from bivalves, marine reptiles, stromatolites, hybodontid teeth, vertebrate coprolites, and other putative fossils. Two papers study conodont biostratigraphy across the Permian-Triassic boundary (PTB) and Induan-Olenekian boundary. Two papers reconstruct the palaeoenvironments of the Early Triassic Chaohu Fauna and Middle Triassic Luoping Biota. Two further papers present new marine δ13C records and biomarker data and link them to volcanic eruptions in Early Triassic times. These new findings are important for understanding the co-evolution between biotic and environmental changes in the aftermath of Permian-Triassic boundary mass extinction.
