New data from the studies of the early Paleolithic stratified sites in Vietnam

Archaeological materials from the sites of Rocktyng 4 and Rocktyng 7 are analyzed in the article. The primary reduction strategy is illustrated by radial cores, single-platform cores with one and two flaking surfaces and unprepared (cortex) platforms, and cores with prepared platforms. The tool kit includes chopper-like artifacts, various side-scrapers, picks, tools with the nose-like protrusions, and one biface. Materials from Rocktyng 4 demonstrate extensive raw material utilization; the proportion of medium and small size flakes is considerable. It attests to extensive modifying of blanks into tools at Rocktyng 4. Trench 2 at Rocktyng 7 represents a workshop with the abundant rough products of stone reduction, while small fakes are practically absent and the proportion medium-size flakes is low, which features suggest that tool were not manufactured at the site.
