Petrified Wood Earth Day Its PCB dodecahedron and inward-facingPetrified wood is a fossil that forms when plant material is buried by sediment and protected from decay. Groundwater rich in dissolved solids flows through the sediment, replacing the original plant material with silica, calcite, pyrite, or another inorganic material.
