What Makes It Petrified? 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. This means that out of all fossils, only the creature itself could be fossilized by petrification.
What are petrified fossils made of?
Most petrified fossils form from quartz minerals, calcite or iron compounds.
What makes petrified?
Petrified wood forms when fallen trees get washed down a river and buried under layers of mud, ash from volcanoes and other materials. Sealed beneath this muck deprives the rotting wood from oxygen — the necessary ingredient for decay.
How do you identify the petrified fossil?
Some bone parts have more pores (porous), while other parts are denser. The pores in porous bone are obvious and can be seen without using any kind of magnifier. In denser bone, it is harder to see or feel. If you cannot find any pores, then you probably have petrified wood.

Can you petrify a human?
Scientists attempted to artificially petrify organisms as early as the 18th century, when Girolamo Segato claimed to have supposedly "petrified" human remains. His methods were lost, but the bulk of his "pieces" are on display at the Museum of the Department of Anatomy in Florence, Italy.
