“中国龙城”又上新了!
近日,山东省诸城市恐龙文化研究中心工作人员在春季野外化石勘察过程中,在诸城市的主要化石遗迹区新发现一处较为完整的水波纹遗迹化石和一些大型恐龙足迹化石。

据介绍,该化石遗迹区地质地貌发育及保存比较完整,经过对周围岩层沉积和遗迹化石点周围地层岩层特征对比分析,初步断定为早白垩世地质地层。

诸城市恐龙文化研究中心科研科普科科长陈树清说,初步确认,这次新发现的恐龙足迹化石点既有蜥脚类恐龙足迹化石,也有兽脚类恐龙足迹化石。前期在距离此处十公里外的化石点,也发现了这两类恐龙足迹化石,证明中生代时期曾有大量蜥脚类恐龙和兽脚类恐龙在这里生活。
据陈树清介绍,此次新发现的水波纹遗迹化石点,在当时是一个滨浅湖,这证明中生代时期诸城地区植被茂密,非常适合恐龙生存。当时气候干旱,湖水非常浅,风吹过后,便在湖边留下了水波纹印痕。

Large dinosaur footprints have recently been discovered in Zhucheng, East China's Shandong Province, a Chinese city that is rich with abundant dinosaur fossils.
Found during researchers' field studies in this new spring season to the local major fossil remains, the trace fossils were identified as belonging to sauropods - large four-legged herbivore dinosaurs - and theropods, bipedal carnivorous dinosaurs. Along with similar trace fossils that have been discovered in the area, the discovery shows that the region used be home to many sauropod and theropod dinosaurs.
Along with the footprints, a relatively complete water-ripple-looking fossil has also been found. According to researchers, it reveals that the place was once a shallow lake.
据了解,诸城处于胶莱盆地南部的断陷盆地,形成于中生代白垩纪,构造变形复杂,地质地层发育齐全,盆地凹陷长期连续沉积,为形成恐龙化石创造了条件。自20世纪60年代以来,诸城先后发现了库沟、掘村、玉皇、臧家庄、侯家屯等30多个恐龙化石埋藏点,埋藏区域近千平方公里。诸城因恐龙化石资源蕴藏丰富,有“中国龙城”之称。
The city of Zhucheng has long been dubbed the "dragon city" due to its valuable dinosaur resources. Since the 1960s, more than 30 dinosaur fossil sites, covering an area of nearly 1,000 square kilometers in total, have been found in the city.
诸城此前共发现恐龙化石25000多块,还曾挖出身长16.6米,高9米的世界最大鸭嘴龙骨架。
More than 25,000 dinosaur fossils have been found in the city. One of the city's most prominent dinosaur discoveries was a fossil of the world's largest hadrosaur species with its body length of 16.6 meters and height of 9 meters.
最近,为应对新冠疫情,以恐龙闻名的诸城市开展全员核酸采样检测,发给大家的贴纸也是“金龙龙”和“火龙龙”~ 这样可爱的小恐龙,有谁不爱呢?
