What? Why?

[jookey2003]

A friend of mine has this stone. I've heard some wild stories that he dreams up about it. Is there any fossils similar or does anyone have an idea of what it might be from. Any help I would apprectiate very much! Thank You!

Looks to me to be a cross section of a concretion, or nodule.

Possibly of a Moqui Marble.

Not a fossil, or alien artifact.

what kind of grain structure do you see?

The pics are a little blurry.

It almost looks carved but concretions are decptive.

It looks like a native American game stone, I have one that is very similar but without the concentric rings carved into if. It could also be a pestle stone that has never been used. Nice find.

Is it basalt, or what? A sharp picture would help.

[jookey2003]

Sorry, It is a picture from him. I will see if I can get him to bring the stone to me so I can take pictures. Honestly, I was hoping to tell him that its nothing special... I guess not

The concentric layers don't have a perfect symmetry, so I think could not be a fossil or an artifact. I vote for a geological origin.

To me it looks like the circles have been carved out, but it's hard to judge because of the poor quality of the photo.

I saw the same possibility; this is exactly why I asked for better images. If it is not sedimentary rock, it can hardly be a concretion.

New pictures! They are again. pictures taken by him. He told me that he no longer lets anyone see the stone.....lol , that is him with the stone.

It was found by him on the lakeshore, Central MN.

Not a fossil - the rock looks igneous, perhaps basalt.

Although strange forms result from natural weathering of layered rocks that one looks as if it's been pecked out intentionally.

It's very similar to the enigmatic prehistoric cup and ring marks found in Europe which are sometimes on a single cobble.

I agree - with the better pictures it does appear to be carved into the rock.

Carved. With what?...and why? The fun of it?

Search cup and ring stones on the web. A number of these have been found in North America. They are Neolithic and believed to be ornamental. The patterns can be found on outcrops and loose stones such as yours.

[TqB]

The carving technique looks like pecking - repeated striking with another tool, perhaps stone.

Didn't know about North American ones but there a lot of Bronze Age/Neolithic ones near where I live in north UK.

I've always wanted to find a portable one!

Very cool. If I found one I would keep it in a Crown Royal sack too

Intersting thread. This specimen had a striking resemblance to an Omar that I found several years back. Here in northern Illinois Omar's (a glacial erratic from Hudson Bay) can be found among glacial cobbles along lakesides, creeks, farmers fields, etc. I even found one on a spoil pile hunting Mazon Creek nodules. Most of the ones I've found have a similar look. A dark colored stone with a single, or sometimes many, circular rings on it that are noticeably lighter in color. Here's a couple of photos of a few I have handy.

And here is on that I found that has an obvious ring indented into the stone. I've always; and still do, believe it's a natural phenomena. Here it is.

So I guess I'm left with a few questions. Is the ring on my stone possibly man made? Could there be a chance the specimen originally posted is a natural phenomena? Or, out of pure speculation, could the original posted specimen possibly be an Omar that has been altered into its current condition?

Nice Rock

I see what you mean that it could be altered for sure.

Ive found a ton like ur top two pictures and the other one is crazy similar to mine.

I keep all odd one just in case its something, and because if I didn't, I'd never find anything and prob not go. I keep round rocks too

2 spots on this guy!

Asking about rocks is done at your own risk. I will not tho.

I like
