Genuine petrified wood fossil specimen. Polished to show detail. Petrified wood (from the Greek root petro meaning "rock" or "stone"; literally "wood turned into stone") is the name given to a special type of fossilized remains of terrestrial vegetation. It is the result of a tree having turned completely into stone by the process of permineralization. All the organic materials have been replaced with minerals (mostly a silicate, such as quartz), while retaining the original structure of the wood. Stand not included. From Indonesia. Approx 6" wide - photo is representative of the one you will receive.
