It has been 4.6 billion years since the birth of the earth. In these billions of years, life on the earth has gradually evolved from a simple structure to a complex, species rich biota, and the earth has finally become a real life planet. It's only a few million years for human beings. According to the latest report released by the United Nations Environment Programme, there are about 8.7 million species of life on earth, including about 6.5 million species of terrestrial life and 2.2 million species of marine life. The reason why we know the existence of these animals is mainly based on the fossils excavated by archaeology. Archaeologists also reduce these animals by studying fossils. In the process, some amazing phenomena have been found.
化石是存留在古代地层中的古生物遗体、遗物或遗迹。化石可以分为四类：实体化石，遗迹化石，模铸化石，分子化石。生物分界一般以一 万年前为界限，-万年前的生物为古生物，一万年前以后的为现生生物。由于自然灾害， 如：火山爆发、泥石流等自然灾害瞬间将其掩埋隔离氧化形，化石中的古生物遗体、遗物或遗迹，从古时候到现在都有化石出现。
Fossils are the remains, remains or traces of ancient organisms in ancient strata. Fossils can be divided into four types: solid fossils, trace fossils, mold fossils and molecular fossils. Generally speaking, the boundary between organisms is ten thousand years ago. The organisms before - 10000 years are paleontology, and those after 10000 years are living organisms. Due to natural disasters, such as volcanic eruption, debris flow and other natural disasters, they are buried and isolated in an instant. Fossils have been found in fossils from ancient times to present.
This is a rare complete fossil with a diameter of 8.5cm Hunran Tiangong, which weighs 300g, is formed naturally. The trace of its shape is clear and the appearance of fossils is lifelike. It is rare that such complete fossils can be formed naturally and can be preserved for tens of thousands of years. After being buried for hundreds of millions of years, the bone fossils have penetrated into the surrounding rocks and have been dyed into the same color as the rocks As a whole, to dig out this fossil is to pack up and dig out the rocks wrapped with fossils. To ensure its integrity to the maximum extent.

In recent years, as a witness of history, the oldest fossils have also entered the view of collectors.
