What is usually concluded about a fossil found in a deeper rock layer?
Answer and explanation
Correct answer: It may be relatively older
The governing geological principle is relative dating: when rock layers have not been greatly disturbed, deeper layers were generally deposited earlier than layers above them. A fossil in such a deeper layer is therefore usually considered relatively older than one in a higher layer. This conclusion is comparative, not an exact numerical age. Option A is correct; B, C, and D contradict the meaning of a fossil and the ordering of strata.
