Petrifaction is the result of a tree or tree-like plants having been replaced by stone via a mineralization process. This petrified wood is from the late Triassic period about 225 million years old. At that time Arizona was near the equator on the south western edge of the super-continent of Pangea. The climate was humid and subtropical. The area was a low coastal plain resting between mountains and the sea.
