摘要
在对呈贡县大渔区龙潭山第2地点的试掘中发现一枚人的下臼齿,它在形态上与现代人的不同,与北京猿人的也有所差别。它带有早期智人下第二乳臼齿的一些形态特征。一起发现的石制品中有石核、石片、砍砸器和刮削器。时代为晚更新世,距今30,500±800年。
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 scrapers, 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.
