The Bear Skeleton is the result of a butchered Bear.
Retrieving the bones from a Bear Skeleton will result in high-quality 4 bear teeth and 12 bones. The maximum quality of the bones and teeth from a bear skeleton is 200. If your survival skill is lower than the original quality of the bones, the the quality of the bone you will receive is the average of your survival skill and the original bone quality (bone q + survival skill)/2.
