This feathered dinosaur is not considered an index fossil because it existed too long ago, and Index fossil are organic remains of animals and plants found in the strata of sedimentary rocks, and serve to date their ages. This is done through the so-called index fossils, so called because they only existed in a certain era or geological period.
