Typological sequence dating
In Europe, West Asia, and Africa, chronological sequences of Upper Paleolithic (UP) or Late Stone Age (LSA) industries, including many regional ‘cultures’ are well established.In general, the beginning of the UP is represented by blade and bladelet production, bone tools, proliferation of personal ornaments, and occasionally mobile and parietal art (e.g., Bar-Yosef ).No direct dates are available at SDG localities 3–5.
A review of the techno-typological characteristics of assemblages found in the Shuidonggou area further expands our understanding of cultural variability, adaptation, and demographic dynamics of modern humans in Late Pleistocene northern China.).
In East Asia, the diversity of cultural entities seems to be greater.
Blade assemblages with western Eurasian UP features and various expedient non-laminar, core and flake assemblages were present in different regions, especially in north Asia (Bar-Yosef and Wang ).
This high ground could have blocked the local river, causing a lake and wetlands to develop in the area after the formation of Terrace 3.
Detailed grain size and pollen analyses of the sections of SDG localities 1, 2, and 7 led to a four-stage model of the depositional environment within the area at the time Terrace 2 was developing.
