12" Arizona Petrified Wood (Woodworthia) Round - Cyber Monday Deal

This is a beautiful round of petrified Woodworthia from the Chinle Formation of Arizona. Woodworthia is one of the more uncommon types of petrified wood within the petrified forests of Arizona. The polishing work on this piece is fabulous.

This round was part of a old petrified wood collection that I recently bought containing petrified wood from many unusual locations. Be sure to keep an eye out for more great specimens.

Petrified wood is the name given to wood that has been turned into stone (fossilized) through the process of permineralization. In this process, all of the organic matter becomes replaced by minerals, while much of the original structure, such as tree rings, is retained. For this to happen, the wood needs to be buried in an environment low in oxygen to prevent decomposition and with flowing, mineral-laden water, so minerals may replace structures. The coloration is caused by various minerals that present in that water during fossilization. For example, red colors are due to iron compounds, greens due to copper, and so on.
