The Paleolithic Artifacts from 2004 Excavation at Liudong Site, Helong County, Jilin Province

The Liudong site is situated on a secondary terrace 20m above the river, at the southeast of Helong County, Jilin Province and its geographical position is 42°19′11″N ,129°6′23″E. The site was discovered in 2002, later investigated in 2004. Stratigraphically, the deposits consist of 5 layers, more than 0180m in thickness. One hundred and forty2two artifacts were collected from the site. The original position of the artifacts can be traced to the third paleosol layer.
The stone assemblage includes flakes, blades, cores, chunks, stone anvil, scrapers, burins, point, chopperΠchopping tool, backed knife. Obsidian is the predominant raw material, constituting 93166 % of the assemblage.
According to the characteristics of these artifacts and the fact that no polished stone tools and pottery sherds were found with them, we suggest that the site is probably in the Late period of the Pleistocene or of the Late Paleolithic.
