Hey everyone!
I was recently fossil hunting at Bolinas in California, which is known for its fossilized sand dollars. While hunting, I found this strange piece and I'm not sure if it's a fossil or not. It's from the Merced Formation, which is from the Late Pliocene to the Pleistocene in California. I have no clue what it is, but I am looking forward to hearing if anyone on the forum does. Thanks!
