Dyuktai Cave (14-13,000 rcbp) on the Aldan River, a tributary of the Lena in Siberia by Dr. Yuri Mochanov ~1968, is interesting because of the discovery of bifacial projectile points, oval and triangular knives, discoidal, Levallois, wedge-shaped cores, multifaceted burins, large side scrapers, small end scrappers on blades, and retouched flakes. These artifacts are associated with large animals, including mammoth. Haynes (1982) sees no obvious connection between Dyuktai and Clovis as a result of the small blades and wedge-shaped cores.

However, temporally and spatially this culture would be an appropriate precursor to Clovis--they existed in Siberia from 30,000 to 11,000 rcbp (Soffer 1993). The Berelekh site (12,200 rcbp) at Yakuria, Siberia, is also worth mentioning (Goebel and Slobodin 1999). The mammoth bone cemetery exhibits microblade technology, bifacial flaking, ivory foreshafts, and red ocher. From this site we know that the Dyuktai culture, with their microblade emphasis, were specialized mammoth hunters.
