6.1 " Unusual Petrified Wood Slab From Madagascar - Rare!

Unusual Petrified Wood Slab From Madagascar - Rare! #235403

This is an unusual petrified wood slab from Madagascar. It doesn't have the typical Aruacaria detail, but instead features grains that branch outward from the center. It was considered to be a species of horsetail, however the preserved bark around the perimeter of the round debunks this as a possibility. It has beautiful coloration, is 6.1" wide, and polished to a glossy finish on both sides. 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. 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.
