Lot: End-Polished Petrified Wood Limbs - 18 Pieces

This is a wholesale lot of Triassic aged (220 million years old) petrified wood limb sections from Ambilobe, Madagascar. The wood comes from Araucaria trees, an extinct type of conifer. One face of each of these limb sections has been polished to show of the inner wood detail; some have both ends polished.

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.
