Jaw Bone Mystery

We were hiking at our favorite beach spot when we found this set of upper and lower jaw bones. There was nothing else left of the skeleton.
In the bottom picture the black part there seemed to be a nose.

Just before we found this in the seaweed and grasses near the high tide line we spotted a mink bounding over the rocks. This is the second time we have seen a mink in this area.

Wondering about the identity of the jaw and if the mink was involved in the owners demise.

Any ideas?
