What plants and animals existed in prehistory and where they lived. "Yanzhou Fossils" is written by Shen Kuo and is from "Mengxi Bi Tan". There have been records about fossils in my country's ancient books and documents for a long time. For example, "Shui Jing Zhu Zi Shui" records the fish fossils excavated from Shiyu Mountain in Xiangxiang County. This is the earliest record of fossils.
