About Petrification:
- Petrification (petros means stone) occurs when the organic matter is completely replaced by minerals and the fossil is turned to stone.
- This generally occurs by filling the pores of the tissue and inter- and intracellular spaces with minerals, then dissolving the organic matter and replacing it with minerals.
- This method reproduces the original tissue in every This kind of fossilization occurs in both hard and soft tissues.
- This typically occurs when the material is buried under sediment and exposed to mineral-rich water over long periods.
- This process is involved in many forms of fossilization and leaves behind many stunning and beautifully preserved fossils.
- An example of this kind of fossilization is petrified wood.
