TOLBAGA SITE This photograph, taken in 1995, shows a Middle to Upper Paleolithic site in eastern Siberia called the Tolbaga stie. The Russian archaeologist is standing on the surface of a 43,000 year old Mousterian site and pointing to a 23,000 year old Aurignacian stratum. Note the Aurignacian layer and how it undulates. This type of soil movement is one indicator of cold climate geology. The dark soil layer above the undulating lighter colored thermo-clastic layer belongs to the Duyktai or Dyktai
micro-blade industry which dates to 19,000 years ago.
