One of the processes involved in petrifaction is permineralization. He is perhaps best known for his work in the artificial petrifaction of human cadavers. In extreme cases, such as petrifaction, the character is entirely disabled. The fossils are well preserved due to extensive petrifaction. Wood from local trees was preserved through petrifaction. In 1905 he played the Doctor in "Passion, Poison, and Petrifaction". However, he uses this opportunity and finishes Jathar, saving himself and other victims from petrifaction. Petrifaction is separated from Rhizocretion by the way they are created. The petrifaction process occurs underground, when wood becomes buried in water-saturated sediment or volcanic ash. Petrifaction is the replacement of organic matter by minerals in fossilization. Petrifaction takes place through a combination of two similar processes&colon; permineralization and replacement.
