I found this while taking around in my garden today. Looks like a small horn of some sort, goat? It's hollow for about 3/8" and then solid. It's fluted.
Chupacabra claw. Its been ground down some though. Likely fell off cause its elderly. I'm sure other Chupacabras have eaten it by now. They usually don't leave much waste and that is why you don't see a dead one all that often in the states.
