They take an estimate on how old the fossil, artifact is then they examine it to tell where the artifact was made, if it is a fossil then tell what ancient creature it is then they can tell what era that creature was from. If it is an unknown fossil they give it a name, but the only way to learn about the past is to decipher hieroglyphics or examine and try to tell what the story on the walls inside the tombs, pyramids, and ancient monuments. I hope you like this answer.
