摘要

摘要: （目的）中-晚三叠世是现代型生态系统构建的关键时期，系统研究该时期生物与环境的协同演变过程对揭示生物复苏机制和生态系统重建规律具有重要意义。（方法）琥珀是探讨中-晚三叠世植物演化和古气候演变的重要载体。本文对青岩剖面雷打坡段的琥珀和伴生的植物化石开展研究，并将全球的中-晚三叠世琥珀的分布与湿润事件进行对比分析。（结果和结论）结果发现青岩琥珀是由松柏类植物伏脂杉生产，琥珀的出现与松柏类植物的辐射演化有关。菊石生物地层表明含有琥珀的地层属于中三叠世安尼期 Pelsonian 亚期。本研究认为琥珀的产出与湿润事件具有对应性，说明湿润事件可能是中-晚三叠世琥珀频繁出现的重要原因。

Abstract: The Middle-Late Triassic was a critical period for the construction of modern ecosystems, and a systematic study of the co-evolution of organisms and the environment during this period is significant for revealing the mechanisms of biological recovery and the reconstruction of ecosystems. Amber is important for discussing the evolution of plants and paleoclimate in the Middle to Late Triassic. Here, we report for the first time the finding of amber in an Anisian marine succession in Qingyan section, South China, which was located in the north-eastern Tethys. Ammonoid biostratigraphy gives a Pelsonian age for the layers bearing amber. Amber has been recovered in close association with plant remains identified as Voltzia sp., indicating that this plant has likely exuded the resin. The fact that fossil resin is restricted only within humid events strongly indicates a climatic control on resin production during the Triassic.
