I find these items quite regularly in the Cookiecutter Creek micro-matrix. Mostly, these are smaller or partial but this one with a length of 11 mm turned up yesterday and I figured it would be a good specimen to try to use for an identification. I say tooth-like because of the shiny black enamel-like surface covering 3/4 of the item. The shape of these items is pretty consistent with the "topside" being shiny, convex and mostly smooth except for apparent "growth rings" and the "underside" of the item showing more texture on the enameled surface and a concavity on the non-black end.
Is this oddity at all familiar? It seems like I should be able to get a grasp on this but I'm sure I'm misidentifying something like a scale or dermal element as a tooth. I'm certain that it will be blindingly obvious in retrospect but I'm hopelessly fogged at the moment.
Cheers.
