I have found this thing in a campanian marine phosphate deposit. It came along with fish and shark teeth. It looks like some kind of tooth, but I have no idea. The brown area is translucent and looks like enamel. Although the grey is thicker and sharp. Any experts on cretaceous fish would be welcome
Ps. This is definately not just a rock, I am fairly familiar with this deposit and can judge a rock from a fossil.
Could anybody I'd this please?
