  • Petrification vs Fossilization: What Is The Difference?
    Petrification is the geological process in which organic material is turned to stone slowly over time This process is involved in many forms of fossilization, and leaves behind many stunning and beautifully preserved fossils
  • How Things Become Petrified - Today I Found Out
    Petrifaction (also known as petrification) is a type of fossilization which leaves living organisms preserved as a type of stone In order for this to happen, a specific set of circumstances has to be present when the organisms cease to live
