I don't have the diagram — could you upload or describe the vertical order of the layers?

General rule: in undisturbed sedimentary layers, younger layers are above older layers (law of superposition). So if the layers from bottom to top are V, W, X, Y, Z then:

- The fossil in layer Z is the youngest — true.
- The fossils in Y and Z are younger than the fossil in V — true.
- The fossil in Y is older than the fossil in W — false (Y is above W, so Y is younger).
- The fossil in X is older than the fossil in Z — true.

If the layer order in your diagram is different, tell me the order (bottom → top) and I'll pick the correct statement.
