Index fossils are the fossils of a plant or animal that were known to be living in a specific geological age, and can be used in determining the date of the rock or rock layer in which they are found. They are also useful in dating and the study of geological formations which help scientists to get a clear understanding of the environment and the life forms that dwelt on the planet even hundreds of millions of years ago.

Fossil Archive, At the clade level, the pattern of expression and release of new exoskeletal segments during post-embryonic development was generally conserved across most species, but the relative timing of different segmentation events could vary, and developmental traits appear to have been relatively labile across the clade's evolutionary history.
