To petrify (petrification) is to undergo a process by which organic material is replaced by non-organic material that leaves the shape of the original organism in place. Fossils are typical examples of petrification where living organisms have died, were buried, and their biological material was replaced by non-biological material through seepage of mineral-laden water from the sediment in which they are buried.
