Prehistoric Petrified Polished Wood Tree Fossil Slice Cross Section. A large and beautiful petrified tree slab. A highly polished cross section of petrified wood, exhibiting a range of wonderful, vibrant colours. The original structure of this prehistoric wood has been completely preserved and turned to stone by the process of permineralization: During burial, water laden with minerals, in this case mostly carbon, iron oxides and manganese oxides, flows through the plant, depositing these minerals into the cells of the organism. Over eons, this forms a beautiful stone mold as the original structure decays.
