Looks like some type of ... rock / skull... I don't know but I'm pretty sure it'd pre culumbia
I never dug any strange things up yet, but I meet many strange people who asked stupid questions.
I once found a tiny "horseshoe". For all intents and purposes it looked like a heavy duty shoe for a working animal, only the thing is, it was small enough to fit in your pocket or on the palm of one's hand. It was very rusty and had clearly been used, but I've never figured out what on earth it would have been attached to and why. I had found other horseshoes in the same field before and this one could have fit entirely inside the open area of the other ones.
