Chronological dating , or simply dating , is the process of attributing to an object or event a date in the past, allowing such object or event to be located in a previously established chronology. This usually requires what is commonly known as a "dating method". Several dating methods exist, depending on different criteria and techniques, and some very well known examples of disciplines using such techniques are, for example, history , archaeology , geology , paleontology , astronomy and even forensic science , since in the latter it is sometimes necessary to investigate the moment in the past during which the death of a cadaver occurred. Dating methods are most commonly classified following two criteria: relative dating and absolute dating. Relative dating methods are unable to determine the absolute age of an object or event, but can determine the impossibility of a particular event happening before or after another event of which the absolute date is well known. In this relative dating method, Latin terms ante quem and post quem are usually used to indicate both the most recent and the oldest possible moments when an event occurred or an artifact was left in a stratum , respectively.

Stable isotope analysis is a scientific technique which is used by archaeologists and other scholars to collect information from an animal's bones to identify the photosynthesis process of the plants it consumed during its lifetime. That information is enormously useful in a wide number of applications, from determining the dietary habits of ancient hominid ancestors to tracing the agricultural origins of seized cocaine and illegally poached rhinoceros horn. All of the earth and its atmosphere is made up of atoms of different elements, such as oxygen, carbon, and nitrogen. Each of these elements has several forms, based on their atomic weight the number of neutrons in each atom.
Carbon nitrogen dating
Nitrogen dating is a form of relative dating which relies on the reliable breakdown and release of amino acids from bone samples to estimate the age of the object. Compared to other dating techniques, Nitrogen dating can be unreliable because leaching from bone is dependent on temperature, soil pH , ground water, and the presence of microorganism that digest nitrogen rich elements, like collagen.
