The optimal water temperature for recent warm-water benthic foraminifera with living symbionts, and consequently for fusulinids, is 20–30°C, while the lower limit is 14–16°C. Fusulinids are often used as index fossils because they were present during the Paleozoic Era and are useful for determining the ages of marine rocks.
