The diagram shows fossils and rock features. How does intrusion X compare to the ages of the other rock layers and fossils in this geologic column?

• Intrusion X is older than layers Y and Z.

• Intrusion X is younger than all the layers.

• Intrusion X is older than the clam and broadleaf fossils.

• Intrusion X is younger than the broadleaf and fern fossils.
