68 Lbs Petrified Wood (Araucaria) Log With Polished End - Madagascar

This is a 68 lbs petrified wood log with one end polished. It is Araucaria, a type of primitive conifer from Ambilobe, Madagascar. The log is 14" long and 8" in diameter. The exterior of the log has a very natural wood look to it, and you could almost mistake it for a recent log.

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.
