Large 15.3" Polished Petrified Wood Round with Fungal Rot - Arizona
This is a gorgeous 15.3" wide round of petrified wood (Araucaria) from the Triassic-aged Chinle Formation of Utah. The wood contains fossilized fungus (the circular formations). This parasitic fungus grew on the tree while it was still alive and has been named Polyporites wardii. This wood is polished to a glossy finish on one side.
It comes with a metal display stand. Felt pads have been applied to the back of the round, allowing for it to be laid flat if preferred.

What Is Petrified Wood
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/impurities present in the water during fossilization. For example, red colors in many cases can be attributed to iron compounds, greens due to copper, and so on.
