The Jingtoushan Site is located in Sanqi Town, Yuyao City, Ningbo, Zhejiang Province, with a history of 7800-8300 years. Since the first excavation from 2019 to 2020, archaeologists have not only discovered a large number of remains of marine shellfish shells and fish bones that were consumed by our ancestors, but also unearthed multiple fishing production tools such as wooden paddles, long wooden sticks, and reed woven fish covers, as well as pottery, stone tools, bone tools, shellfish, wood and other production and living utensils. According to expert evidence, the Jingtoushan site is currently the deepest buried, oldest, and best preserved ancient coastal shell mound site along the coast of China, inhabited by the earliest Chinese coastal fishermen. The discovery of this site provides extremely valuable materials for exploring the origin of Hemudu culture in the lower reaches of the Yangtze River and even the origin and development of Chinese marine culture. Sun Guoping, the leader of the archaeological team at the Jingtoushan site, introduced that more than 8000 years ago, the people of Jingtoushan who lived here built a coastal fishing village facing the ancient Ningbo Bay, continuously utilizing marine resources for hundreds of years. Later, it experienced rapid sea level rise and was submerged by seawater. The site has been buried by sedimentary silt over 5 meters thick to this day. Due to the deep burial of the site in a marine sedimentary environment with ultra-low altitude and high groundwater, archaeologists creatively adopted technical measures such as steel structure foundation pits and reinforced concrete frame structure foundation pits, effectively ensuring scientific excavation in special burial environments and accumulating successful experience for excavation work of similar sites in coastal areas. The Jingtoushan Site has been selected as one of the top ten archaeological discoveries in China for the year 2020. (New Society)
