The Karasai site: The first stratified Mesolithic assemblage in eastern Kazakhstan

In 2019, a joint Russian-Kazakh expedition discovered the first stratified Mesolithic locality in eastern Kazakhstan. Excavations at the Karasai site revealed a rich Early Holocene cultural layer (Layer 2). The lithic industry includes elements of all stages of lithic production. Cores include low-backed prismatic and narrow faced varieties and the tool assemblage is dominated by non-geometric microblade inset, fragmentary points, borers, micro-burins and microlithic scrapers. The Mesolithic age of the finds is confirmed by two AMS radiocarbon dates between 10,000–8,500 cal years BP. The Karasai industry most closely resembles lithic assemblages dating to the beginning of the Early Holocene in northern Kazakhstan.
