Answer:

Older fossils are found in deeper layers of sedimentary rock.

Explanation:

The relationship between undisturbed sedimentary rock layers and fossils is that older fossils are found in deeper layers of sedimentary rocks.

This is one of the premise of the law of superposition and principle of fossil and fauna succession.

  • An undisturbed sequence is one in which the sedimentary layers have been arranged sequentially.
  • The oldest is at the bottom and the youngest on top.
  • Also, fossils grade in this manner too.
  • The oldest fossils will be in the oldest bed which is the deepest layer.
  • The youngest bed will contain the youngest fossils in like manner too.
