3.2" Petrified Wood (Schinoxylon) Section w/ Frass - Blue Forest

This is a 3.2" wide, polished section of a petrified wood (Schinoxylon) limb from the famous "Blue Forest" in Eden Valley, Wyoming. It shows amazing grain detail and agate through the interior and around the limb. At the center of the wood within the agate, frass produced by boring insects can be found preserved in excellent detail. This colorful section of petrified wood has been highly polished on one side.

It comes with an acrylic display stand.

This petrified wood 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. These casts have preserved incredibly fine details in the wood, providing researchers with a wealth of information about these ancient trees. A paper on the formation of this petrified wood can be found at the link below.
