4.35" Petrified Tree Fern Limb End-Cut - Brazil
This is a beautiful, 4.35" wide end-cut from a limb of Permian-aged petrified wood from a tree fern (Tietea singularis or Psaronius brasiliensis). The specimen is missing the detail that would help determine the specific species. 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 along one end to display the very interesting, fossilized internal structure of the plant.
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.
