3 items need help identifying

[FtWayne123]

The first 3 pictures are of what I think is some kind of corn grinder. It has a slight indention in the bottom making me think someones finger formed the indention over time. Was found by me several years ago in Ohio Co., KY. The 4th and 5th pictures are of some flint object I found in my yard. I'v never found any Indian related items in my yard before. My neighbor found an arrowhead while digging his pond though. Does it look to be anything or just an odd looking piece of flint? It has a hole in it that goes through it but not in a straight line. The last picture is a piece of flint on top and some other type of stone that I'm wanting to know what it is? there seems to be a lot more of it than flint in the fields here.

I think your first piece is a pestle which would have been used for crushing and grinding.

So since I found just the pestle, would there be some kind of bowl or hole in a rock near that area?

[John G. Scoggins]

I would think there's a good chance of finding whatever they were using it with.It would be cool if you end up with a big mortar to put it in.

I agree with pestle and the rest just rocks. Good find. Thanks.

That would be really cool. I found it right up against a rather large rock(to big to pick up and move) and only one corner was sticking out of the dirt so i picked it out and knew it was from Indians. The rock it was laying up against has about 12 inches sticking out of the dirt and an unknown amount under the ground. Would it be possible that that rock/boulder was used in some way or was it placed there for no reason?

You would have to see the rock, look for indentations where they used the grinder on it. When they moved from camp to another camp they would take the pestles and leave the mortars behind so sometimes you wont find them together. They turned the mortars upside down in case they returned to that spot for reuse. If it is the mortar there will be a flat spot or a hole in it and sometimes what is called a dimple, it is circular in the stone. Very nice bell pestle!
