Paleontologists still commonly use biostratigraphy to date fossils, often in combination with paleomagnetism and tephrochronology.

The good dates are confirmed using at least two different methods, ideally involving multiple independent labs for each method to cross-check results.Unlike observation-based relative dating, most absolute methods require some of the find to be destroyed by heat or other means.This family of dating methods, some more than a century old, takes advantage of the environment’s natural radioactivity.Both plants and animals exchange carbon with their environment until they die.
