Human adaptive behavior in the Late Paleolithic of the Suifen River Basin

During the Late Paleolithic, the Suifen River Basin in northeastern China provided suitable conditions for the local prehistoric human to survive. Three types of lithic industries exist in the Suifen River Basin, including the flake industry, the blade industry, and the microblade industry, but artifacts from the flake industry continue to dominate.The study of the lithics revealed that the human occupants visited the Suifen River Basin during the Late Pleistocene. They chose suitable river terraces as campsites, collected igneous rocks from river floodplains or bedrock outcrops, and produced flakes by hammering, pressing,or bipolar technique,then retouched them into tools with various functions, and lived a hunting and gathering life in this area.
