WHO'S ON FIRST? A RELATIVE DATING Several dating methods exist, depending on different criteria and ques, and some very well known examples of disciplines using such ques are, for example, history, archaeology, geology, paleontology, astronomy and even forensic science, since in the latter it is sometimes necessary to investate the moment in the past in which the death of a cadaver occurred.
