Hello, I found this at the beginning of 2018 and haven't given it much thought until I saw the post from 2016 about a strange specimen that looked like Native Americans carved. The topic has been linked below.

 

 

Below is the specimen I found and was curious if its the same process and is also counter septarian? I also thought they might be beekite rings. Any thoughts and ideas would be greatly appreciated.

I agree with beekite, but would like to know the size.

 Smallest is 2 mm and the largest is 10 mm.

Looks beekite.

 

@Raggedy Man. The 'can't figger this one out' post is one of my favorites. 

Mine too! I was absolutely shocked it turned out to be geological.

At first glance it looks like an animal with an eye. Pretty cool. Can I see a pic of the entire rock and a close-up of a circle? Thanks!

How did these structures form?

Each dot is 50,000,000 years:

Hadean............Archean..............................Proterozoic.......................................Phanerozoic...........

Thanks for the cropped photo. Is the blueish gray chalcedony? It looks very waxy. I've never seen or heard of beekite. Very unusual but interesting.

Silicification as a method of fossilisation
The method of fossilisation which is the most variable is replacement.  This can result in fossils which show fine detail or, as in the fossil in Figure 1, it can result in a mere outline of the specimen being preserved.  The method which results in this is silicification, where silica is introduced into specimens as a replacement of the shell mineral calcite, particularly a form known as beekitisation.

Beekite is a form of chalcedony, a microcrystalline form of quartz, named after Henry Beeke, Dean of Bristol (1751-137).  It is usually recognisable as orbicular structures, concentrically layered spheroids.  Apart from the presence of orbicular structures of beekite there are a number of ways to identify if a fossil is silicified: Natural weathering will dissolve the limestone matrix in which the fossil is preserved leaving the fossil proud (see Figure 3), steel will not scratch it and if acid is applied it does not fizz as limestone does.

So is this specimen pictured considered a fossil?

Beekite

 

Miriam Webster defines beekite as : a pseudomorph of chalcedony after coral or shell.

 

Pretty much the same thing Tony said, ... only he said it better. :P

Concerning the counter septarian post

I thought it was surely carved by humans, but earth and the elements are the supreme artist. We just can't compete.

Here is photo of some beekite I have. It can get loopy.
