Nice Polished Arizona Petrified Rainbow Wood Limb Round Endcut Late Triassic

Collector notes

The Arizona petrified forest is probably the best known in the world due to its vibrantly colored “rainbow wood” and the Petrified Forest National Park. This petrified forest is part of the Late Triassic-aged Chinle Formation and extends over a huge area--around 100,000 acres--but only a small portion is located within the national park. The fossilized wood is approximately 225 million years old! The dominant tree species in the forest is Araucarioxylon arizonicum, a type of conifer related to the living pehuén, or monkey tree.
