There are many processes that lead to fossilization, including permineralization, casts and molds, authigenic mineralization, replacement and recrystallization, adpression, carbonization, and bioimmuration.In this case the fossil consists of original material, albeit in a geochemically altered state.This chemical change is an expression of diagenesis.The empty spaces within an organism (spaces filled with liquid or gas during life) become filled with mineral-rich groundwater.Minerals precipitate from the groundwater, occupying the empty spaces.
