Arizona Green Petrified Wood (Chromium)

This petrified wood comes from a tree fall in the Winslow, Arizona area which reflects the presence of 2% or more chromium in the specimen, and is highly desired by collectors.

This petrified wood originates from the Chinle Formation, Triassic era – and is approximately 220 – 200 million years old. This specimen was once a conifer tree that paleobotanists have named Araucarioxylon Arizonicum. It is now extinct. Its closest relatives today are the Monkey Puzzle Tree of South America and the Norfolk Island Pine tree.
