Carbon-14 is also passed onto the animals that eat those plants.After death the amount of carbon-14 in the organic specimen decreases very regularly as the molecules decay.For example, JJA Worsaae used this law to prove the Three Age System.For more information on stratigraphy and how it is used in archaeology, see the Stratigraphy glossary entry.The method is still a standard for cemetery studies.Absolute dating, the ability to attach a specific chronological date to an object or collection of objects, was a breakthrough for archaeologists.

Cross-dating of sites, comparing geologic strata at one site with another location and extrapolating the relative ages in that manner, is still an important dating strategy used today, primarily when sites are far too old for absolute dates to have much meaning.The scholar most associated with the rules of stratigraphy (or law of superposition) is probably the geologist Charles Lyell.
