6.4" Petrified Tree Fern (Tietea) Round - Brazil

Petrified Tree Fern (Tietea) Round - Brazil #281919

This is a beautiful, 6.4" wide round of Permian-aged petrified wood from the tree fern, Tietea singularis. The inner wood detail is very fascinating and displays a variety of colors. It comes from the Araguania petrified forest of Brazil and there is only one legal mining claim in the region. It has been nicely polished to a glossy finish on both sides to display the very interesting, fossilized internal structure of the plant.

It comes with an acrylic display stand.

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.
