Which Fossil Species Would Make The Best Index Fossil? Trilobites serve as good index fossils, letting geologists date the age of the rocks that they are in. Which species make the best index fossils? The best index fossils are common, easy-to-identify at species level, and have a broad distribution—otherwise the likelihood of finding and recognising
