Is it a mammoth tooth fragment or just a cool rock?
Gemini is convinced it’s a mammoth tooth fragment while Claude is standing by its geological decision. A scratch test shown in one image shows the porous layer is easily scratched with steel (circled in red) while the gray layer is not. This was left in the backyard when I got the house (Oklahoma).
