An Upper Palaeolithic culture of northeast Siberia with the type site being the Dyuktai Cave at the confluence of the Dyuktai and Aldan rivers. It is characterized by bifacial tools of various shapes, burins on flakes and blades, blades, and microblades. The industry was associated with mammoth, bison, and horse bones and is similar to the Denali complex of Alaska. The cave's earliest occupation dates to c 33,000 BC and the culture seems to have ceased c 10,000 BC. The people who first migrated into North America may have been from this cultural group and it may be ancestral to the earliest lithic technologies, in particular the bifacially flaked points, of North America.
