Answer:
Fossils generally helps in relative dating of rocks.
The Trilobites are considered the oldest in this rock sequence when we apply the principle of superposition of strata.
The principle states that "in an undeformed/undisturbed sequence of rock, the oldest is always at the bottom while the youngest is on top" .
This principle therefore explains why the Trilobites at the base are considered the oldest.
