3. 4. The Principle of Original Horizontality states that when a new rock layer forms, it is usually laid down on top of another layer that was laid down at some earlier time. 5. Fossils may be imprints, or the actual remains of ancient life, preserved in the rocks. ***BONUS*** 10 points Describe ONE reason why the fossil record is incomplete.
