Round Limb section of petrified tree with exterior bark still present and One Side is Polished
Good limb specimens with good colors are more rare than the larger tree trunks. This is probably due to their smaller diameter causing them to be more prone to being destroyed or damaged during catastrophic events such as volcanic eruptions or flooding prior to make it to the petrification stage.


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