How Fossils FormConceptual concept
Check understanding
- Describe the basic sequence: organism dies, buried in sediment, minerals replace remains over time
- Explain why fossilisation is rare — most organisms decompose before being buried
- Use the words 'sediment', 'minerals', and 'rock' correctly when explaining
“If your child made a salt-dough fossil at school, could they explain how real fossils form underground over millions of years?”
