Explanation:
Detailed explanation-1: -Features of Index Fossils: Index fossils come from plant and animal species that once lived on the Earth. The features that determine whether a species makes a good index fossil include a unique physical appearance, wide distribution of their habitat, and know dates in which they lived on the planet.
Detailed explanation-2: -That’s called the fossil record. Paleontologists have been collecting fossils from sedimentary rock layers around the world for over two hundred years. Their goal is to figure out the succession of species through all of geologic time. Once that succession is known, it serves as a scale of geologic time.
