  • Origin: Arizona, USA
  • Size: L52cm W52cm D2cm
  • Description: Araucarioxylon arizonicum from the Triassic period (ca. 220 million years ago) cut in cross-section and polished to reveal the rich colors for which this site is so famous, while retaining texture around the edges.
  • Additional information: Petrified wood, fossil formed by the infiltration of minerals into the spaces between and within the cells of natural wood, usually silica (silicon dioxide, SiO2) or calcite (calcium carbonate, CaCO3). The petrified forests of the Western United States are silicified wood in which the tree tissue has been replaced by chalcedony (cryptocrystalline quartz). Often this replacement is so accurate that both the internal structure and external shape are faithfully reproduced.
