Eden Valley Petrified Wood Wyoming Polished Round
Lovely round of Eden Valley Petrified Wood from Wyoming that has been slabbed, and polished on one face, natural rough on the edges.
The polished face is 6 inches by 3.5 inches and it is .9 of an inch thick.
This is Petrified Wood (Edenoxylon) from Eden Valley, Wyoming. It is found in the Bridger Formation (part of the Green River Formation), and from the Eocene Epoch and about 50 million years old.
Eden Valley Petrified Wood, which is found near, and named after, the town of Eden, located in the western central part of Wyoming. The 80-mile-long area includes three major collecting areas: the Blue Forest, Big Sandy Reservoir, and Oregon Buttes.
This piece was from the Big Sandy Reservoir petrified wood area that is north of Farson and northeast of the Big Sandy Reservoir. This area is known for Petrified Palm Wood.
This petrified wood is often found with a layer of fossilized algae. The driftwood and trees in these shallow water areas became coated with the algae, and as the water began to evaporate and dry, calcium mixed with the algae to form a hard but porous coating on the wood. As the algae dried it shrank away from the wood, leaving a space that was later filled with minerals. As the wood decayed, the wood was replaced by silica and calcite leaving petrified replicas of the original piece of wood. As the minerals coated the inside surface of the algae cast, perfect impressions of the outer surface of the wood were duplicated and preserved features not found in fossil wood anywhere else in the world.
