A friend of mine spotted this on the beach at Belmar, NJ yesterday February 2nd. This is kind of an unusual locale, adjacent to the jetty at Shark River Inlet where the Shark River meets the Atlantic. In the past my buddy and I have found small beachworn fossil shark teeth at this spot, so we thought for old time's sake we'd take a quick look again. We didn't find any teeth (there's much less fine gravel there now than in the past) but he did find this, which is way bigger than anything we've found here before. I have some guesses but I would like other eyes on this too in case I'm missing something obvious.
Thanks in advance
