He found in in the Illinois River near Ottawa. I looked at it under the lens and it looks to have a lot of shiny bits of silica in it. Its water worn of course. I think it broke off a larger piece also. Looks like two materials fused together. It has a dense feel to it but the rare earth magnet did not grab to it. Its not a fossil just a cool little rock.

    My guesses are probably way off kilter, but it may be hematite, or an ore of some kind. Because it didn't attach itself to a magnet, it probably isn't hematite.

        Hi LM. It's a better guess than anything I can offer. But HST, it makes me wonder--what kind of a critter makes one looking like that? lol
