How do petrified fossilization differ from carbonized fossils? Petrified fossils do not need carbon to be fossilized.
Petrified fossils are only made in desert type environment.
Petrified fossils need a lot of carbon in order to be come a fossil.
Petrified fossils dissolve all original parts including carbon.

When a fossil organism is subjected to mineral replacement, it is said to be petrified. For example, petrified wood may be replaced with chalcedony, or shells replaced with pyrite. ... Some are preserved as carbonized films, or preserved unchanged like recent fossil shells, or fixed in amber like fossil insects.

Hope it helps, some how.

a boiling water reactor does not boil the water. a pressurized water reactor boils the water faster. a pressurized water reactor is heated directly by the core. a pressurized water reactor does not use fission.
