Petrified Wood, also referred to as a "petrified tree," is a unique variety of fossilized remains of terrestrial vegetation. It is created when Wood is buried beneath sediment and maintained by the permineralization process.
A natural cast of Wood is produced as a result of this process, in which minerals dissolved in water penetrate into the cells and voids of natural Wood and harden. The organic material decays over time, leaving a spectacular fossil in its wake.
The continents of Asia, North America, Argentina, and Egypt all contain petrified wood. It is most frequently found in arid and desert areas.
