  4. How Fossils Form Many years went by.This is a lizard fossil. The sand and mud turned into rock.The lizard lived long ago. The print of the lizard got left in the rock.The lizard died. Now it is a fossil.It got covered with sand and mud.4 5
  5. What can we learn Sometimes plants and animals stop getting what they need.from fossils?
