My kids and I were jetskiiing not far off the coast of North Wildwood and stopped at an island called Champagne Island. As we walked the perimeter of the Island I noticed this (pictured below) in a few inched of water. I gave it to my cousin who is a marine biologist at Rowan University in Glassboro NJ and he let a bone specialist there study it. The bone specialist said it was from a 10-15,000 year old mammal most likely a sea-lion. Thats all the information I have on it and it presently sits on a shelf in my living room. So I came here to share my story and see what you guys think. The piece is about 7" long.
