1、山东科技大学学士学位论文摘摘 要要本文选择山东地区晚白垩世的恐龙化石及其赋存地层为研究对象，开展一些针对性的研究，以期在沉积学、地层学和古生物学等方面获得一些新的认识和进展。山东发现恐龙化石的地区主要在胶莱盆地。莱阳的恐龙以鸭嘴、鹦鹉嘴龙居多，另外还有剑龙，谭氏龙(鸟龙类)等多种。时代属白垩纪，多存于王氏系的红土中或灰绿土中。其分布呈带状，主要分布在金岗口，红土崖、将军顶、柳行、陡山、横岚埠等处。山东恐龙化石的另一发现地诸城是一个中生代地层较为发育的小型盆地，含有大量的古生物化石，其中尤以恐龙化石最为丰富。诸城恐龙种属繁多，且范围广，埋藏丰富，是全国少有的一处恐龙化石宝库。本文对山东恐龙化石的
2、分布、恐龙的生活习性、以及其生活环境和化石的埋藏学特征进行了研究，得出山东的恐龙化石出产多在缺少侏罗纪地层的鲁东地区，该地区主要为一套辫状河流相和冲击扇相沉积。研究发现，赋存化石的沉积序列主要由泥石流、洪泛平原、辫状河道等微相类型组成。在其地层沉积特征的基础上，结合所发现的恐龙化石，本文认为，山东莱阳诸城盆地在白垩纪时期气候温暖,雨水充沛,河流交织,湖泊广布,植被繁茂,生机盎然。同时本文在对恐龙化石集群埋藏研究后发现，恐龙是在迁徙洪泛平原时遭遇突发性洪水或大规模泥石流、滑塌等灾害，导致生物集群死亡事件的发生。关键词关键词：山东， 恐龙化石， 白垩纪， 沉积环境AbstractThe dinos
