Yes, just a rock.

The first photo had me wondering (a little).
The rest look very much rock-like.

I don’t see the normal geometry for a tool, unless it’s the mid section of core or something but I’d lean just a rock.

I think it’s flint so the right kind of rock. It only looks like it has creek chatter though.
