How do you know which fossil is oldest and which one is youngest?

• Younger fossils are built as layers of sediment pile up so the lower the fossil the younger it is.

• Older fossils get covered by more layers of sediment so the lower the fossil the older it is.

• Older fossils are built on layers of sediment so the higher the fossil the older it is.

• Newer fossils get covered by more layers of sediment so the lower the fossil the newer it is.
