Arizona Petrified Picture Wood Araucarioxylon Polished Rock
This is a sliced and polished on one face, natural rough everywhere else, piece of Arizona Picture Wood that is 3.5 inches by 3.4 inches wide and .8 of an inch thick.
It is "bark" only on one edge. The bottom edge first picture has some areas where the wood probably rotted away before petrifying and it didn't polish as well and has some natural fracture lines (see last picture).
This specimen is known as “picture wood” for its black bands and dendrites, as opposed to “rainbow wood” which has more "rainbow" colors and few if any dendrites.
The most important find in the world of Petrified Wood is in Northern Arizona. The majority of the petrified wood here is Araucarioxylon arizonicum, a prehistoric type of conifer.
This "Petrified Forest" was made a National Park in 1962.
This Petrified Wood is found in the Chinle Formation and comes from the Triassic Period around 220 million years ago.
In Northern Arizona tree trunks as large as 213 feet long were buried under several hundred yards of sediment. Over the course of time the wood was replaced by cryptocrystalline quartz, largely chalcedony and jasper.
Northern Arizona Petrified Rainbow Wood is famous because it is found in so many colors. It is especially known for its reds and yellows.
Of the billions of trees that ever lived, only a fraction were in the right circumstances to fossilize, and only a small fraction of those are solid or have pretty colors or patterns.
In 1988 the Arizona state legislature designated petrified wood the Arizona state fossil.
Metaphysical Properties of Petrified Wood: Petrified Wood in general is said to be a stone of patience, and slow and steady growth. It is believed that Petrified Wood can help one overcome limiting emotional patterns handed down through one's ancestors.
