中国东北中-晚 侏罗世燕辽生物群产出了大量保存精美的动植物化石。相对于系统古生物学研究取得的巨大进展，燕辽生物群的埋藏学研究还相对较少。有关这一特异埋藏化石群如何形成的一系列基本问题，如什么事件引起生物的大量死亡、生物遗体尤其是陆生动物是如何被搬运和埋葬到湖泊中的、哪些导致了化石的特异埋藏等，都还没有得到充分的研究。.生物集群死亡事件以及生物遗体在湖泊中的搬运和埋葬过程必然会在化石和沉积物中留下证据。对死于生物集群死亡事件的化石及其赋存岩层进行生物层积学研究，无疑是解决燕辽生物群埋藏学研究中存在的问题的关键。本次研究拟以宁城道虎沟及与其邻区为案例，采用详细的野外调查与现场挖掘和统计相结合的方法，通过分析这一地区燕辽生物群保存的沉积环境和埋藏相，探讨引发这一地区中-晚侏罗世生物集群死亡的事件成因、生物遗体的搬运和埋葬过程以及影响化石特异埋藏的主导因素。

Numerous exceptionally preserved fossils have been uncovered from the Middle-late Jurassic Yanliao Biota in northeastern China. Comparing with the great achievement in study of systematic paleontology, few taphonomic studies have been carried out. Many questions concerning the preservation of the biota remain open. These include the causes of mass mortalities, the subsequent process of transport and burial of the organism remains, especially those who lived on land, and the environmental factors that influenced the formation of exceptional preservation. .The fossils from mass mortality events and their embedding sediments contain key information about the causes of the events and the process that how the organism remains were transported and buried to lakes. Biostratinomic analysis on the fossils and their embedding beds is critical to answer these aforementioned questions. In the proposed project, the Daohugou and its adjacent areas, Ningcheng, Inner Mongolia are selected as a case study. By means of intensive field investigation, high-resolution excavation and detail statistics of taphonomic attributes, this project addresses to understand the causes of mass mortality events, the subsequent process of transport and burial of the organism remains, and the environmental factors that influenced the formation of exceptional preservation addresses to understand by analyzing the paleoenvironment under which the Yanliao Biota were preserved and the taphofacies of the Yanliao Biota.
