Activity Tim Keller posted an image in the group Beach Fossils from the myFOSSIL app 1 month, 3 weeks ago 1 month, 3 weeks ago 1 month, 3 weeks ago Found at Flag Ponds, MD. At first I thought were shark teeth but now thinking crab claws. One on right maybe a tooth? All approx 1/2 inch (1.27 cm). Any ideas?
