Quality Araucaria Petrified Wood Slab - 8.6"

Quality Araucaria Petrified Wood Slab - #7630

This is a high quality slab of petrified Araucaria (extinct Conifer) wood from Ambilobe, Madagascar. It is 8.6x5.2" and one side has been polished to a mirror like finish showing off the amazing mineralization of this fossil. It is from the early Triassic period, approximately 220 million years old, close to the time the first dinosaurs appeared on the planet.

This specimen is made out of particular high quality petrified wood from the location which was hand selected for exceptional coloration. It was polished by one of the top petrified wood polishers around so it doesn't have any of the dull spots or scuff marks seen on lower quality material.

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 that present in that water during fossilization. For example, red colors are due to iron compounds, greens due to copper, and so on.
