WHAT ARE FOSSILS?
WHAT TYPE OF ROCK ARE THEY FOUND IN?
HOW ARE THEY FORMED?
THE 5 STEPS ON HOW FOSSILS ARE FORMED!
1. dies, and is buried by mud or silt.
2. the soft tissue decomposes leaving only bones.
3. over time sediment builds over the top, into rock in between rocks.
(if in water)
4. over time from pressure the clay might rise above water.
5. weathering, erosion, + deposition will wear away rock
6. the fossil will be exposed!
