A seal skeleton from Champlain Sea deposits near Hull, Quebec, formerly identified as probably belonging to a young harp or harbor seal, actually represents a seven year old ringed seal.

The specimen suggests that fast ice existed near the western margin of the Champlain Sea during winter and spring.
