If the rock has been undisturbed, the oldest rock will be at the bottom, therefore, the oldest fossils will also be at the bottom. the youngest rock will be at the top, therefore, the youngest fossils will be at the top. Absolute Dating-When you can figure out through testing the exact age of the fossil
