  • Flying Saucer flint?

There was no other pieces that looked similar. On the relatively flat bottom, in the middle, there is a slick, hard button about 5/8” in diameter. The rest of the surface is a limestone looking rock that is smoother on top and looks like layers on the bottom.
    I have heard of flying saucer flint, but have not seen one. Don't Click image for larger version  Name:	70FA0329-270D-4398-AEFD-BEFE01F6ED60.jpeg Views:	0 Size:	155.2 KB ID:	526796 feel like breaking it up. Looks too interesting.

      That is a head scratcher. I haven't seen anything like it. Just curious but are you sure it's not some kind of industrial waste? There are some concretes that are fine grain and even made from limestone dust that can appear like a natural stone. Not saying you don't know your artifacts because I know you do, it's just that looks more like a poured, hardened material judging just from the two pics. I'll be following this post to see what others might know about it.

        I’m 99% sure it is a natural formation. Found miles from any place that might have used concrete like that. Can also see it is made up of many layers.

        Ok, I figured you'd know, plus having it in hand of course. Hopefully someone has an idea.

      Sometimes concretions form in this shape. Only way to know is to bust open, but DONT!

        Cool find, some of the limestone formations in the Midwest/Mississippi river valley have lots of types of chert nodules. I've seen some flat "pancake" nodules in some areas.

          We don’t have anything like this within 50 miles of where I found this. I’m thinking it had to be brought here by someone a few hundred years ago.

        Look at this rock. One side rounded/domed, other side flat with a “button” in its middle. It’s a concretion that’s been broken open ! Pretty neat.... The button is probably the lil’ organic whatever around which the concretion formed.

          Other than the color, looks similar.

        Hay again Charles. I think what you have is a fossilized Coral. Some like yours aren't as defined. The dimple is the nucleus where it started to grow from This one is Limestone and Calcite. Kim

          You may be right! There is some definition that looks like coral if you look close enough.

          That’s a dandy specimen Kim!

        I thought you might think so, if you saw a more defined example. They are very similar in contexed. Kim

            Here is one thought . I find so many iron ore pieces that are perfect cylinders . Might have been under water and coral grew on it millions of years ago .
            Don't know if your area is that zone .
            it’s an interesting site to literally see the earths crust cooled and if it were under water that could have happened .
