5" Realistic, Carved Petrified Wood Skull
This is a beautiful, polished skull that's out of petrified wood.. This skull has been meticulously sculpted and polished into the shape of a realistic skull. The patterns and colors of the wood are unique and there are multiple agate filled pockets throughout the wood. The underside of the skull has been hollowed-out, making the specimen closer in resemblance to a real skull.
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.
