- Comments
- SfFl-VP: Vertebrate remains were collected from various localities to establish length of survival and processes of decay of bone and soft tissue on land surfaces underlain by deep permafrost and under prolonged seasonal snow cover. The series also compares dates of terrestrial and marine mammals. BM-1751, -1753 estimate the apparent age of marine bone. BM-1753 and -1754 indicate the long survival of bone and associated soft parts (BM-1753 had intervertebral disc) in relatively unaltered state on the arctic land surface. BM-1754 agrees with the archaeological evidence (Schledermann, 1978, 1981; McGhee, 1980).
