@vperez Whoa. That’s a worn fossil.
@llundgren. I agree. I don’t think its a tooth either.
At first glance, because of the curvature of the fossil and what might be an articular surface, my reaction was I was looking at a phalanx or the distal end of a radius. Though, I’m not sure now after looking through some other photos I have. I don’t know how much of the shape is from weathering. But IMG 3756. If that is an articular surface, it looks weird, but might be the key to figuring it out.
