If a fossil is found at the top of a rock layer, it is generally:

Explanation:
In sedimentary rock layers, younger layers sit on top of older ones. So a fossil found toward the top of the rock sequence is generally younger than fossils found in deeper, older layers. This gives a relative age—you can say it’s newer—without knowing the exact date. Rock type or disturbances can complicate things in real cases, but the basic rule remains: higher layers tend to preserve younger fossils.
