Types of fossil dating techniques
Dating is very important in archaeology for constructing models of the past, as it relies on the integrity of dateable objects and samples.
Many disciplines of archaeological science are concerned with dating evidence, but in practice several different dating techniques must be applied in some circumstances, thus dating evidence for much of an archaeological sequence recorded during excavation requires matching information from known absolute or some associated steps, with a careful study of stratigraphic relationships.
This usually requires what is commonly known as a "dating method".
The stratigraphy of an archaeological site can be used to date, or refine the date, of particular activities ("contexts") on that site.
For example, if a context is sealed between two other contexts of known date, it can be inferred that the middle context must date to between those dates.
It was the case of an 18th-century sloop whose excavation was led in South Carolina (United States) in 1992.
Thus, from the oldest to the youngest, all archaeological sites are likely to be dated by an appropriate method.
