Fossil or just unique mineral deposits

Not sure if this rock is a fossil or unique mineral deposit that created uniform circles within the rock. My amateur guess would be maybe coral fossil?

Exactly where did you find it? Could be agate.

Found it in the badlands of South Dakota.

Agate is found in that area.

It looks geological to me. Beautiful specimen!

 

 

Mark.

 

Fossil hunting is easy -- they don't run away when you shoot at them!

Geological, I agree. :)

Nice specimen!

Might want to cut it. South Dakota has some nice agates: Fairburn and Prarie Agates.

My goal is to leave no stone or fossil unturned.
