5.7" Polished, Petrified Wood (Araucarioxylon) - Arizona

Polished, Petrified Wood (Araucarioxylon) - Arizona #244086

This is a brilliantly colored, 5.7" wide section of petrified wood (Araucarioxylon) from Arizona. One end of the petrified has been polished while the exterior surface has a natural texture.

It comes with an acrylic display stand.

This wood is similar to petrified wood found in the Petrified Forest National Park near Holbrook, Arizona. Its petrified forest encompasses nearly 100,000 acres, and is almost entirely represented by the extinct conifer Araucarioxylon arizonicum.

The petrified wood from Araucarioxylon arizonicum happens to be the state fossil of Arizona. It is frequently referred to as "rainbow wood" because of the large variety of colors some specimens exhibit. The reds and oranges come from hematite inclusions within the silica, the yellows from limonite, and the purples from extremely fine hematite spherules.

Araucarioxylon arizonicum is estimated to have grown more than 150 feet high and dominated the tropical forests in what is now Arizona nearly 225 million years ago.
