Which step in the fossilization process is being shown by this picture?

• Step 1: The organism dies

• Step 4: The organism is buried in sediment over time

• Step 2: The organism is buried in sediment over time

• Step 5: A fossil is discovered

Which step does NOT belong in the fossilization process?

• The organism dies

• The organism is buried in mud and sediment over time

• The soft tissue decays and minerals fill in the spaces

• The bones change into rock over time

• A fossil is discovered

Which step in the fossilization process is being shown by this picture?

• Step 1: The organism dies

• Step 2: The organism dies

• Step 3: The soft tissue begins to decay and minerals fill in the empty space

• Step 4: Time turns sediment and minerals into rock/stone

All organisms that die become fossils

• True: when an organism dies it gets fossilized over time

• False: some organisms don't want to be fossils

• False: it takes special circumstances and millions of years to become a fossil

• True: every rock is a fossil
