Faunal succession states that older fossils do not exist from any time before the Mesozoic era. This information indicates that the environment has not changed.

Answer 1

The correct response is:

**Faunal succession states that older fossils are found in deeper geological layers. This information aids in relative dating of plant and animal life.**

This concept helps scientists understand the environments of the past by revealing the chronological order of fossilized remains, allowing them to infer the ecological conditions that existed at different periods in Earth's history.
