In 1997, a study on the skeletal material from 56 Pleistocene-period East Beringian (Alaskan) wolves based on uncalibrated radio carbon dating showed a continuous population from 45,500 years BP to 12,500 years BP, and one single wolf dated at 7,600 BP.
In 1997, a study was undertaken on the skeletal material from 56 Pleistocene-period East Beringian wolves from permafrost deposits in Alaska. Uncalibrated radio carbon dating showed a continuous population from 45,500 years BP to 12,500 years BP, and one single wolf dated at 7,600 BP.
