| 摘 要： | 在四川安岳恐龙化石埋藏地上侏罗统遂宁组、蓬莱镇组地层中，发现了Scoyenia,Palaeophycus,Akolithos,Muensteria,Planolite,Cylindricum,Thalassinoides,Arenicolites等8个遗迹属，共10个遗迹种，归属为Scoyenia遗迹群落。遗迹群落与沉积构造特征表明遂宁组、蓬莱镇组沉积环境为泛滥平原，其中恐龙化石埋藏于泛滥平原上洪泛湖泊的滨湖砂岩之中。恐龙集中埋藏的原因可能是其死亡后被搬运于滨湖环境。

| Abstract: | Scoyenia, Palaeophycus, Skolithos, Muensteria, Plano li te, Cylindricum, Thalassinoides,Arenicolites etc. belonging to Scoyenia ichnocoe nose have been discovered in the Suining and Penglaizhen Formations as Buried Pl aces of Dinosaur Fossils in Anyue, Sichuan. The ichnocoenose with sedimentary st ructures indicate that the Suining and Penglaizhen Formations were composed of f loodplain sediments and the trace fossils were buried in floodplain lakeshore sa ndstone. The fossils might be transported into lakeshore environment. |
