Abstract: New excavations were carried out at the Shibazhan Paleolithic site in Tahe Country, Heilongjiang Province. This paper describes and analyzes 58 artifacts: 38 pieces of stone were unearthed from B and C layers, and 20 pieces of stone were collected from the ground surface nearby. Blades are important components of this assemblage, which is similar to the Shuidonggou site located at Ningxia Hui Autonomous Region. A bifacial specimen and a round-end scraper collected on the ground exhibit close resemblance to the stone tool types from some microlithic sites in northern China and the far eastern region of Russia. The absolute date of the four layers of this site were dated by optically stimulated luminescence (OSL), and two cultural stages were established, namely 25 ka BP (Level C) and 10 ka BP (Level B), respectively.
With its location in northeastern China and on the basis of morphological characters of these stone artifacts, the Shibazhan Paleolithic site provides important data for studying northeastern Asian human migration and cultural communication during late Pleistocene and early Holocene.
