And, what about other findings like fossil fish, plants and insects?The first method that scientists use to determine the age of rocks is relative dating.In this method, scientists compare different layers of rock to determine an ordered sequence of events in geologic history.Add to that the knowledge that everything that ever was, still is, but is in another form.The few leaves that escaped the transformation by being preserved by some chemical action that possibly caught them as they floated downward, or forests of trees petrified into rocks, make for exciting adventures of discovery.
