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 detail. 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.
