Organisms that later became good index fossils typically thrived during specific geological time periods and had widespread distribution. Examples include trilobites, ammonites, and brachiopods, which were abundant and had rapid evolutionary changes. Their distinctive features allow geologists to correlate rock layers and determine relative ages of the strata. These fossils are crucial for understanding the Earth's history and the timing of events in the geological record.
