Paleozoic Fossil Sites

　　1. Dazhaimen Fossil Site

　　Located 2 kilometers west of the county town, between Shaba Village Committee of Dianyang Town and Dazhaimen Village Committee of Heyuan Township, the outcrop has a vertical height of about 500 meters. The geological section, from bottom to top, contains strata from the Silurian to the Carboniferous periods, including Paleozoic fossils dating back 450 million to 280 million years.

　　2. Xibiantang Fossil Site

　　Located west to northwest of Xibiantang in Heyuan Village, Heyuan Township, about 4 kilometers east of the Heyuan Township government. This site is a Devonian fossil site, featuring Paleozoic fossils dating back 400 million to 340 million years.

　　3. Maocaoban Fossil Site

　　Situated 1 kilometer north of Zhuojunmen Village Committee, Heyuan Township, between the committee and the natural village of Maocaoban. This is also a Devonian fossil site, containing Paleozoic fossils from 400 million to 340 million years ago.

　　4. Xujia Banpo Fossil Site

　　Located 3 kilometers west of Zhonghe Village Committee, Renhe Town, at Xujia Banpo. This is an Ordovician fossil site, with strata containing Paleozoic fossils dating back 500 million to 450 million years.

　　This relatively complete and typical set of Paleozoic geological sections preserved within Shidian County is referred to by geologists both in China and abroad as the "Home of Chinese Cyathocrinida" due to its rich abundance of Chinese sea lily fossils. It provides valuable physical evidence for studying the complex geological evolution and the origin and evolution of life in western Yunnan, making it highly significant to geologists around the world.
