Chikhan Agui

Chikhen Agui is a rock shelter in the Gobi Altai, west of Tsagaan Agui cave. Its deposits preserve stone tools, animal remains, hearths and beads made from ostrich eggshell. Small stone tools found in the upper layers date to roughly eight to eleven thousand radiocarbon years ago. A charcoal sample from a deeper layer gave a date of about twenty-seven thousand years, pointing to a much earlier period of occupation.
