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.
