Rough Arizona Rainbow Petrified Wood (25 oz)

This is a rough (unpolished) piece of Arizona "Rainbow" petrified wood. This is similar petrified would which is found in the Petrified Forest National Park. The petrified forest encompasses nearly 100k acres and this wood comes from land outside of the park.

It most likely came from the extinct conifer Araucarioxylon arizonicum which happens to be the state fossil of Arizona. The petrified wood of this tree is frequently referred to as "Rainbow wood" because of the large variety of colors some specimens exhibit. The red and yellow are produced by large particulate forms of iron oxide, the yellow being limonite and the red being hematite. The purple hue comes from extremely fine spherules of hematite distributed throughout the quartz matrix.

Araucarioxylon arizonicum is estimated to have grown more than 150 feet high and dominated the tropical forests in what is now Arizona nearly 225 million years ago.
