5.5" Polished Oligocene Petrified Wood (Pinus) - Australia

This is a beautiful polished slab of Oligocene-aged petrified wood from the Central Highlands of Australia. It is believed be from a tree in the pine family. The excellent polishing job on the cut face allows for the very detailed interior wood structure to be observed.

It comes with an acrylic display stand.

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.
