Thick Petrified Wood Slice - 13.5"

This is a large slab of petrified wood cut from a log of Araucaria (extinct Conifer) wood. It is 13.5x10" and one side has been polished to a mirror like finish showing off the amazing mineralization of this fossil. This petrified wood from Madagascar is early Triassic in age (~220 million years old) close to the time the first dinosaurs appeared on the planet. It comes with a display stand.

Please note there is a repaired crack running through the slab

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.
