I live in Wyoming. So I discovered none of them myself. Bought at a mineral and gem show. A couple are obvious like the Meg and Sandshark. The Meg was found in south Carolina. That's the only information I have. If someone could identify and educate me on any or all of the teeth. I would love to know everything about them, I would appreciate it so much. and does anyone know what the white stuff is on the meg tooth? Why is it there? #fossil
