What is fossil stone made of?
Fossil stone is a material formed, changed, or altered by a process called fossilization. This process replaces organic materials in rock or stone with minerals that seep into the rock or other object eventually hardening.
How are stone fossils formed?
Sometimes ground water dissolves the buried bone or shell, leaving behind a bone- or shell-shaped hole or imprint in the sediment. This is a natural mould. If water rich in minerals fills this space, crystals can form and create a fossil in the shape of the original bone or shell, known as a cast fossil.
Are fossils always stone?
