Item Description
This classic and well-formed copper "skull" is certainly one of the most unusual forms in the Mineral Kingdom and is from the famous Copper Country of Michigan. Pieces of this quality are much sought-after. Molten copper invaded a conglomerate bed and surrounded a large, rounded cobble. The cobble dissolves away, leaving the casted "skull" of the cobble. This very fine example looks like a broken dinosaur egg.
