- Comments
- QaJu-VP: Walrus bones were collected from a 10-20 square metre area that was poorly vegetated. The skull was one-third embedded, and other bones were more completely buried. GSC-3081 agrees closely with a previous date (S-1392; 2420 +/- 65 BP; Dyke, 1979) on a tusk from the same collection. The GSC determination was carried out as an inter-laboratory check. Dyke noted that the high elevation, about 103 m, implied an age of about 9500-9000 BP. Thus the animal must have crawled inland and died well away from shore.
