摘要：蘑菇山北遗址位于内蒙古自治区呼伦贝尔市扎赉诺尔区蘑菇山一带，发现于1980年，同年和1990年两次采集和试掘，获得了比较丰富的石制品，是中国东北地区一处重要的旧石器时代晚期遗址。2019年8月进行了新的调查和试掘，获得石制品近400件，主要分布于地表和地层表土的角砾堆积中，全部为打制产品，原料为就地取材的安山岩，类型包括石核、石片、断块和石器（工具）等，工具类的器型较大，石器技术成熟，主要属于石片石器工业。试掘的T3探方出土了丰富的打制石制品，以小型石片为主，是该遗址的新收获。根据石制品的技术特点和类型组合分析，该遗址的年代应为旧石器时代晚期。

Abstract: The Mogushanbei site is located at the north foot of a hill called Mogushan in Zhalainuoer District, Hulunbeier City, Inner Mongolia, China. The site was discovered in 1980, and plenty of chipped stone artifacts were collected at that year and 1990. Based on the technological features of the stone artifacts, the site was considered to Late Paleolithic. The site was reinvestigated in August of 2018, and about 400 chipped stone artifacts were collected from the surface and the uppermost breccia layer of three tested pits. Artifacts were made of local andesite of the Mogushan hill. The lithic assemblage includes cores, flakes, chunks, and retouched pieces, and the size of the artifacts is relatively large. However, many small flakes were yielded from the Test Pit 3 which was not recognized on the surface materials. By a preliminary analysis of the lithic technology, the assemblage more likely resembles the simple core-flake technology in North China, and could be a Late Paleolithic assemblage.
