    Description

    LARGE PETRIFIED WOOD SLICE
    Araucarioxylon arizonicum
    Triassic
    Chinle Formation, Arizona

    This magnificent section of a 210 million year old petrified log was recovered from just outside the Petrified Forest National Park in Winslow, Arizona, renowned as one of the finest localities for petrified wood anywhere in the world. The logs of this Triassic forest were completely covered with silica-rich sediments over 200 million years ago, and over the course of time different minerals seeped into the wood, slowly replacing its organic structure on a cellular level, and creating the incredible natural canvas that we see today. When these logs are sliced open and polished they reveal a swirling riot of color.
    Here the predominate color is blue, along with splashes of purple which form a pocket of amethyst crystals. Deep clouds of black and gray are interspersed with patches of vivid red, tan and cream. The surface has been brought to a high-polished finish, the better to display the incredible patterning that preserves the formation of the tree's original growth rings. This large and highly esthetic petrified wood round is rimmed with the original well preserved rough-textured bark on a gently curved complete cross-section, approximately 44 x 37 x 1¾ inches.


    Estimate: $18,000 - $22,000.
