what can be concluded about the age of the fossil? a it is older than the shale. b it is younger than the…

Explanation:

Step1: Recall geological principle

In undisturbed rock - layers, the lower layers are older and the upper layers are younger (principle of superposition).

Step2: Analyze rock - layer order

The sandstone is on top of the limestone, and the shale is below the limestone.

Step3: Determine fossil age

Since the limestone is below the sandstone, a fossil in the limestone is older than the sandstone. And since the shale is below the limestone, the fossil in the limestone is younger than the shale.

Answer:

D. It is younger than the shale.
