Recently, the research team of the Gantangqing Site in Yunnan, composed of professional personnel from many Chinese and foreign scientific research institutions, discovered 35 well - preserved wooden tools at the site. These wooden tools are 300,000 years old and are the earliest wooden artifacts found in East Asia so far. The relevant research results were published online in the international renowned academic journal Science at 00:00 on July 4, Beijing time. The details are as follows:Site Introduction: The Gantangqing Site is located on a slope about 5 kilometers south of Fuxian Lake, Jiangchuan District, Yuxi City, Yunnan Province, with an altitude of 1836 meters. It was discovered in 1984 and first excavated in 1989, with a large number of stone artifacts and animal fossils unearthed. It was excavated again during the two field archaeological seasons in 2014 - 2015 and 2018 - 2019, yielding rich stone artifacts, animal fossils, wooden materials, and plant seeds.Features of Wooden Tools: Among nearly a thousand wooden materials unearthed from the Gantangqing Site, 35 were identified as artificially processed wooden tools. The tree species of these wooden tools are mainly Pinus, accounting for about 70%, and about 3% are Fagaceae, and the rest are broad - leaved tree species. These wooden tools are diverse in shape, and 32 of them have clear artificial repair marks at the tip/blade/bottom, with a tip for digging processed. Among them, 2 are large - scale digging sticks that need to be held with both hands; 4 have a unique hook - shaped tip, which may be used to cut off plant roots; the rest are small - scale digging tools that can be held with one hand.Dating Method: The research team used a variety of dating methods, including paleobiostratigraphy, paleomagnetism, thermoluminescence, and electron spin resonance, to obtain the age of the wooden tools unearthed from the Gantangqing Site as 300,000 years ago.Significance of the Discovery: The discovery of dozens of wooden tools at the Gantangqing Site is a world - class major archaeological discovery. It not only fills the gap in the research of Paleolithic wood products in China, but also is of great significance for exploring the origin, processing technology, function, and evolutionary development process of wooden tools. At the same time, it is of important academic value for understanding the cultural and technical characteristics of East Asian Paleolithic humans, as well as their cognitive, adaptive, and survival abilities and ways.
