Answer 2

Answer

Explanation:

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.
