Raw Natural Arizona Petrified Wood 1.11LBS/750Grams/120mm Paperweight Felt Pads See Pics. The image shows a piece of Arizona petrified wood, the fossilized remains of ancient trees. Here's some information about it: Formation: It forms when trees are buried in sediment and volcanic ash, preventing decay, and minerals replace the organic material over millions of years. Composition: Petrified wood is primarily made of quartz, with colors from trace minerals like iron, carbon, and manganese. Age: The petrified wood in Arizona's Petrified Forest National Park dates back 211 to 218 million years. Petrified wood is the fossilized remains of ancient trees that have undergone a process known as silicification, where organic material is replaced by minerals, transforming the wood into stone. This phenomenon often occurs in areas with significant volcanic activity, where trees were buried rapidly under silt and volcanic ash, preventing decay. In particular, the Triassic Era saw the dominance of gymnosperms, such as conifers and ginkgos, which contributed to many preserved specimens. Unlike typical fossils, petrified wood retains a three-dimensional structure, revealing intricate details of the original tree, including its cellular makeup. Notable sites for petrified wood include the Petrified Forest National Park in Arizona, renowned for its extensive and varied wood specimens. Globally, petrified forests can also be found in regions such as Greece, Argentina, and Namibia, each providing valuable insights into the Earth's climatic and ecological history. Researchers study petrified wood to understand ancient ecosystems, plant evolution, and the relationships between extinct and modern species. This ongoing research is crucial for comprehending how climatic changes have influenced plant life over geological periods.
