Fossils found in deeper layers of rocks are generally considered signs of what?
Answer and explanation
Correct answer: Older organisms
In undisturbed sedimentary rock, layers are usually deposited one above another, so deeper layers formed earlier than upper layers. Fossils preserved in those deeper layers therefore generally belong to organisms that lived earlier. Option A is correct. The other choices reverse the relative-age principle or do not describe biological fossils at all.
