Petrified Wood - Woodworthia arizonica
This piece of petrified wood originated from the Chinle Formation 225 million years ago. The Chinle Formation is a Triassic continental geological formation spread across Nevada, Utah, northern Arizona, western New Mexico, and western Colorado.
During Chinle time, flowering plants did not exist. However, the then leafy ecosystem boasted large conifers that could grow up to 150 feet tall and span 9 feet wide. When these trees fell, some were buried quickly by sediments, depriving oxygen and replacing the wood with minerals that hardened to form petrified wood.
