地球的生长让昆明滇池周围有着太多值得骄傲的东西:澄江帽天山“寒武纪生命大爆发”的化石群,海口耳材村的“海口鱼”和“昆明鱼”标志化石。在晋宁的梅树村,又有一项具有世界意义的地质发现。近代以来,人们采用用放射性同位素方法,来确定地球历史各个阶段岩石形成的时间,划分不同的地质时代,并结合岩石中的生物化石记录,用生物进化的历史来对应和确定岩石形成的历史。这样,不同的生物化石, The growth of the earth has so much to be proud of around the Dianchi Lake in Kunming: the fossil group of the “Tianshan Mountain” of the Cambrian in the Chengjiang River and the “Haikou Fish” and “Kunming Fish” Logo fossil. In plum village of Jinning, there is another geological discovery of the world. Since the modern times, radioactive isotopes have been used to determine the time of formation of rocks in all stages of Earth’s history. Different geological times have been divided into several categories. Based on the records of living fossils in rocks and the history of biological evolution, the history of rock formation has been identified and determined. In this way, different biological fossils,
