山东诸城恐龙动物群的发现、埋藏环境及分类

    Discovery, taphonomic environments and classification of Zhucheng dinosaur fauna in Shandong Province

    • 摘要: 诸城恐龙骨骼化石主要集中埋藏于库沟、龙骨涧、臧家庄、西见屯等化石点, 发现了鸭嘴龙、角龙、暴龙、甲龙、蜥脚类和窃蛋龙类恐龙。为进一步系统梳理诸城地区恐龙化石赋存埋藏特征, 结合前人研究和笔者近年研究发现, 诸城可能存在3种鸭嘴龙, 至少存在2种暴龙科恐龙。诸城恐龙化石最主要的埋藏相类型为泥石流沉积相。白垩纪晚期, 诸城地区干旱的气候可能是该地区恐龙死亡的原因。诸城恐龙动物群与北美地区晚白垩世恐龙组合相似, 对白垩纪恐龙的迁徙、分布、演化、生存环境、板块构造等研究提供了丰富的材料和证据。

       

      Abstract: Kugou, Longgujian, Zangjiazhuang and Xijiantun are mainly fossil sites, and hadrosaurs, centrosaurinae, tyrannosaurs, ankylosauria, sauropods, oviraptorosauria were discovered in Zhucheng.Previous research and the author's recent studies show that there may be three kinds of hadrosaurs and at least two kinds of tyrannosauridae in Zhucheng.The main taphonomic facies type of dinosaur fossils is mud flow deposits.Draught climate may have played important roles in the mortality of dinosaurs.Zhucheng dinosaur fauna is similar to the dinosaur assemblage in North America, providing abundant materials and evidence for the study of Cretaceous dinosaurs' migration, distribution, evolution, living environment and plate tectonics.
