Answer 2

"Ground water rich in minerals will start to impregnate all of the pores and cellular spaces inside the organic material. These minerals will crystallize and settle into the shapes of the cells and other structures that are slowly breaking down. When the last remnants of organic material finally changes their chemical composition, all that is left is the stone-like fossil of the original living organism, created by the crystallization of the minerals present. Not all of the organic material is lost, however. Although most petrified plants are rock-like in weight and density, about 1%-15% of the material is still organic."
