Before more precise absolute dating tools were possible researchers used a variety of comparative approaches called relative dating these methods some of which are still used today provide only an approximate spot within a previously established sequence think of it as ordering rather than dating.

isotope vs nuclide a nuclide is a species of an atom with a specific number of protons and neutrons in the nucleus for example carbon13 with 6 protons and 7 neutrons the nuclide concept referring to individual nuclear species emphasizes nuclear properties over chemical properties whereas the isotope concept grouping all atoms of each.
