The species was tiny, with adults being only slightly larger than a sea otter Homme Nike Air Force 1 Low Leather QS Blanche Pas Cher , Boessenecker said in a statement.


The partial jaw, with several well-preserved teeth, was found in the 1980s in a rock formation dating from 15 million to 17 million years ago in the U.S. state of California, but had been misidentified as belonging to a walrus species.

"The mystery remains of why there has only been one of these fur seals ever found
