5.2" Tall Petrified Wood (Schinoxylon) Section - Blue Forest, Wyoming

This is a 5.2" tall, section of 50 million year old petrified wood from the famous "Blue Forest" in Eden Valley, Wyoming. It was formed when trees died and fell into a swamp where they were rapidly covered by algae. This formed casts that preserved the original bark surfaces of the trees and kept them from decaying. Eventually the algae casts and the spaces between them were filled in by minerals, often in exquisite, crystalline form.

One face of the specimen has been polished to a mirror like finish and the bottom has been cut flat so that it displays well on a flat surface.
