Opalized wood. Petrified wood is basically fossilized wood that has had it’s organic matter replaced by a mineral such as agate, bit by bit, as it decomposes. The wood structure is maintained, but the wood fibers are slowly changed into stone. Sometimes a jasper, quartz, pyrite or even opal(shown above) can be found fossilized in wood.
petrified wood is the state gem of washington even though it’s technically a fossil
Petrified Wood is the name of the first single from my misandrist metal band, DWÖRKIN.
