- Description: This Quercus Simulata slice shows the growth lines of a stinking water oak. The "Golden Oak" comes from the world-famous and difficult to access Stinking Water locality, as the wood-bearing layers are covered by a tough volcanic cap, which further complicates the extraction of this phenomenal petrified wood species. The heavily agatized and finely preserved disc allows for a "mirror" shine on the polished surfaces of the cut specimens. Impressive are the central "eyes" with some of the diagnostic black spots within a cream kidney-shaped area irregularly outlined in brown.
- Additional information: Petrified wood, fossil formed by the penetration of minerals into cavities between and within cells of natural wood, usually by 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 The petrified forests of the western United States are silicified wood in which the tree tissue has been replaced by chalcedony (cryptocrystalline quartz).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.
