6.7" Petrified Tree Fern (Tietea) Slab - Brazil

This is a beautiful 6.7" wide slab of Permian-aged petrified wood from the tree fern Tietea singularis. The inner wood detail is fascinating and has a bright pinkish-red color. 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 on one side to display the very interesting fossilized internal structure of the plant.

An acrylic display stand will accompany your purchase.

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.
