- Comments
- BiGc-VP, Pakenham: This date on bones from a rather young white whale, deposited in situ with marine pelecypods, corresponds closely with a date of 10,420 +/- 150 BP (GSC-454) on bone from another young white whale found in the Ottawa area. It seems reasonable that these small, gregarious whales that are well-adapted to inshore and freshwater conditions would be relatively common as fossils in the western part of the Champlain Sea during its later stages.
