Answer:
Newer
Step-by-step explanation:
Because it is like when you place a plant and its roots underground and cover it up. You have the newer dirt going over the newest roots and the roots are close to the top
(If you aren't satisfied with that explanation here's another one) :
A hundred years ago dinosaurs existed and then they died and their remains were buried under dirt. However, we know that the fossils aren't anywhere near the top. Over time fossils get buried under layers of dirt the newer ones will be near the top because they haven't had time to be more buried.
