Abstract: The Xishan site , situated at the Xishan Hill of the Xintunzi town in Fusong City, Jilin Province, was excavated in 2002. The site consists of 3 layers, with stone artifacts found in Layer 2, the yellow-clay layer. Altogether 30 stone artifacts, all made of obsidian were collected from the site, including blade cores, flakes, and microblades. In particular, the blade core weighed 17.4kg with a blade scar of 322mm in length and 44mm in width on the platform, which is rarely seen. The remains of an oval2shaped basalt stone circle was also found, which is made up of both an inner and outer circle, with the largest dimensions being 6.5m (length) and 4.8m (width). This evidence may represent a hut or a temporary place for the people at that time, and is a very important archaeological discovery in this area. According to the stratigraphy alignment and the lack of polished stone artifacts and pottery, the site can be dated to the upper Paleolithic or later.
