Millions of years ago, this stone was not a stone, it belong to the organic matter of a tree. Petrifaction or fossilization occurs only when the fallen tree is quickly buried where it is void of oxygen that would accelerate the decaying process. Water leaves behind trace elements like silica that replaces the organic cellular structure.
