| 摘 要： | 四川省安岳马门溪龙是继合川马门溪龙和自贡恐龙化石群发现以来又一重大发现。本文通过面上地质调查、地质剖面及沉积构造方面综合分析,确定了安岳恐龙化石赋存于侏罗系上统遂宁组(J3s)中上部鲜紫红色泥岩、小型砂岩透镜体中以及侏罗系上统蓬莱镇组(J3p)下部厚层-块状长石石英砂岩中。埋藏特征为滨湖相的原地埋藏和经过短距离搬运的异地埋藏。

| Abstract: | The mamenxi dinosaur fossils discovered in Anyue Sichuan Province are another important discovery after the discovery of Hechuan mamenxi dinosaur and Zigong dinosaur fossil groups.Based on the comprehensive analysis of geological survey,geological section and sedimentary structure,it is determined that the Anyue dinosaur fossils exist in bright purple red mudstone in the middle and upper part of Suining formation(J3s),small sandstone lens and thick block feldspar quartz sandstone in the lower part of Penglai formation(J3p).The burial features are in-situ burial of lakeside facies and long-distance transportation. |
