【摘要】：甘肃和政古动物化石地质遗迹是一个以丰富的渐新世至更新世的古动物化石为特色的地质奇观。和政古动物化石地质遗迹主要发育4个古动物化石群:底部红色砂砾岩中埋藏着距今30 Ma的巨犀动物群;下部河湖地层中,埋藏着13 Ma前的铲齿象动物群;中部以红土为主,埋藏着距今10 Ma左右的三趾马动物群;上部黄土堆积中埋藏着2 Ma前的真马动物群。这些古动物化石地质遗迹记录了渐新世以来地球历史的丰富信息和演化过程,是研究青藏高原隆升历史的重要证据。甘肃和政古动物化石地质遗迹孕育了分布密集、保存完好、种类繁多的古动物化石,且甘肃和政临近我国"一带一路"战略中"丝绸之路经济带"的中联点。这些世界罕见的古动物化石,具有不可替代的珍藏价值、游览价值、科普价值和科学研究价值。
[Abstract]:The fossil geological remains of Hezheng Paleontology in Gansu Province are characterized by abundant fossils from Oligocene to Pleistocene. In the red gravel rocks at the bottom, there are giant rhinoceros fauna about 30 Ma from now. In the lower part of the river and lake strata, there is a shovel elephant fauna 13 Ma ago. In the middle of the region, the red earth is the main body, and the three-toed horse fauna about 10 Ma old is buried in the middle part of the region. In the upper loess deposit, there is a true horse fauna 2 Ma ago. These fossil fossil geological relics record the abundant information and evolution process of the earth history since Oligocene. It is an important evidence to study the uplift history of Qinghai-Xizang Plateau. The fossil geological remains of ancient animals in Hezheng County Gansu Province have given birth to a variety of fossils of ancient animals which are densely distributed well-preserved and varied. Gansu Hezheng is close to the "Silk Road economic belt" in the "Belt and Road" strategy of our country. These rare ancient animal fossils in the world have irreplaceable treasure value and tour value. The value of science popularization and scientific research.
