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.

Polished section of petrified wood showing annual rings. Most dinosaur bones are permineralized. Petrified wood: Permineralization is the first step in petrification. In petrification, the cellulose cell walls are completely replaced by minerals.
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]

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.
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.
