I bought this from the $1 table in the rough from a wholesale shop. However after polishing and cleaning it up it looks too pretty to be worth only $1, I was told by the owner of the store that this may be a piece of Coprolite. The pictures online don't look anything similar to this, can someone please identify this for me?
Any effort is greatly appreciated
