Tree remains that have undergone petrifaction, as seen in Petrified Forest National Park. In geology, petrifaction or petrification (from Ancient Greek πέτρα (pétra) 'rock, stone') is the process by which organic material becomes a fossil through the replacement of the original material and the filling of the original pore spaces with minerals.
Petrified log at the Petrified Forest National Park. Petrified wood (from Ancient Greek πέτρα meaning 'rock' or 'stone'; literally 'wood turned into stone'), is the name given to a special type of fossilized wood, the fossilized remains of terrestrial vegetation.
Petrified wood are fossils of wood that have turned to stone through the process of permineralization. [3] All organic materials are replaced with minerals while maintaining the original structure of the wood. The most notable example is the petrified forest in Arizona. [4]
Fossil hikes and walks in Petrified Forest. Red Basin Clam Beds: This 8.5-mile round-trip hike takes visitors past interesting rock formations and fossilized mollusks. Marsh said that even though ...
The Petrified Forest is known for its fossils, especially fallen trees that lived in the Late Triassic Epoch, about 225 million years ago. The sediments containing the fossil logs are part of the widespread and colorful Chinle Formation, from which the Painted Desert gets its name.
Petrified Forest calls itself a Triassic park. It preserves more than 200 million years of history, including its namesake petrified wood. It’s the only place chindesaurus fossils have ever been ...
Fossil wood is wood that is preserved in the fossil record. Wood is usually the part of a plant that is best preserved (and most easily found). Fossil wood may or may not be petrified. The fossil wood may be the only part of the plant that has been preserved; [99] therefore such wood may get a special kind of botanical name.
The upright fossil trees of the Gallatin Petrified Forest in the Gallatin Range and the Yellowstone Petrified Forest at Amethyst Mountain and Specimen Ridge in Yellowstone National Park, occur buried within the lahars and other volcanic deposits comprising the Eocene Lamar River Formation as the result of periods of rapid sedimentation associated with explosive volcanism.
