Results are presented of bone accumulations at two maternity dens adjacent to the west coast of Namibia between 1982 and 1996. Of 14,585 bones, 73%, or 10,639, could be identified representing different food items. Fur seals accounted for 84% of the assemblages, other carnivores 9%, ungulates 2% and birds 4%. The rate at which bones accumulated over time did not vary significantly. There was a tendency for bones used to identify individuals, such as mandibles and long bones, not to disintegrate at the same rate as smaller bones.
