5.5" Petrified Wood (Schinoxylon) Slab - Blue Forest, Wyoming

This is a beautiful 5.5" slice of petrified wood (Schinoxylon) from the famous "Blue Forest" in Eden Valley, Wyoming. It shows amazing grain detail and agate inclusions. This colorful slice of petrified wood has been highly polished on one side, by one of the top polishers out there. It doesn't have any of the tool marks or scuffing that might be left by lesser quality polishers.

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 and kept the trees from decaying. Eventually the algae casts and the spaces between them were filled in by minerals, often in exquisite, crystalline form. A paper on the formation of this petrified wood can be found at the link below.
