- Description: This polished hickory-like fossil wood slice reveals in detail the age growth rings as seen in the detailed images. Very rare due to its size.
- Additional information: Petrified wood, fossil formed by the penetration of minerals into the cavities 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 The petrified forests of the western United States are silicified wood in which the tree tissue has been replaced by chalcedony (cryptocrystalline quartz).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 form are faithfully reproduced.
