Petrified wood is a fossil that is formed when plant material is replaced with silica, calcite, pyrite, or another inorganic material such as opal that has been dissolved in the groundwater that flows through the sediment. The result is a fossil of the original woody material that often exhibits preserved details of the bark, wood, and cellular structures.  This limb cast shows exception details of the growth patterns.
