I found these both in an area where a couple of arrowheads and a some broken pieces have been found but these two rocks along with one more that looks just like them I found on a different day a couple hundred yards away look all to similar to make me think that they are possibly tools or something used by an ancient people, but I don't know I'm not to good at identifying stuff like this. Also the pictures just aren't as good as seeing them. Any help would be great please and thanks.
