I found these together as I walked the sandbar down to the boat last few mornings ago.
Cant date 'em, because they were not in any strata, but they were mudded together. Definitely hand made, though.
The container/dish is hacked out from a walrus skull, its the socket that holds the tusk. VERY hard bone and it could have had many forms/uses.
The baleen strip is sharpened at both ends and would have been first soaked and then folded or coiled and bound with sinew. Then it would have been frozen into a fish or meats and left where a predator like a Wolf would have found and eaten it, its digestion releasing the "trap" to straighten with dire results......and death comes from within.
I would think tracking it down would be the final solution.....
