Petrified Wood - Washington State 61777169589f5dabe7600c37abe58afb They show a convergent evolutionFrom ancient Greek meaning "wood turned into rock", Petrified Wood is an unique form of fossilization. In some instances all the organic matter has been replaced by minerals (usually a silicate, such as quartz) during a process called permineralization replacement. However, many petrified wood specimens undergo a unique fossilization process, where silicates bond with the cellulose structure of the wood, thereby preserving organic matter. Regardless
