What are the three necessary conditions for Fossilisation? Preservation of remains (protection against scavenging, erosion and environmental damage) High pressure to promote mineralisation of remains (i.e. turn hard body parts into fossilised rocks) Anoxic (low oxygen) conditions to protect against oxygen damage and prevent decomposition by saprotrophs.
