Abstract: A human deciduous molar (dm2) has been found at Locality 2 of Longtanshan, associated with paleolithic artifacts total 107 in number. The molar is similar to the dm2 of early Homo sapiens in morphology, but exceeds the latter in size. The artifacts include cores, flakes and tools. The tools may be divided into two types: choppers and scrapers. It is worthy of notice that one of the serapers, a convex side-scraper, is similar to that found in Lunan, Yunnan Province.
The associated fossil mammals suggest an Upper Pleistocene age and the C14 dating results in 30, 500±800 years B. P. for this site.
