Dendrochronology cross dating
This is admitted because of the simple reason that some botanical species, whether extinct or not, are well known as belonging to a determined position in the scale of time.
For a non-exhaustive list of relative dating methods and relative dating applications used in geology, paleontology or archaeology, see the following: Same as geologists or paleontologists, archaeologists are also brought to determine the age of ancient materials, but in their case the areas of their studies are restricted to the history of both ancient and recent humans.
However, we can look for certain years that offer good "signals" (very thin or very wide rings) and identify them in each core and confirm they occur at the year they should in each core.
The skeleton plot is the tool used to discover these "signal years" and subsequently cross-validate each core for exact dates.
Thus, to be considered as archaeological, the remains, objects or artifacts to be dated must be related to human activity.
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.On the other hand, remains as recent as a hundred years old can also be the target of archaeological dating methods.It was the case of an 18th-century sloop whose excavation was led in South Carolina (United States) in 1992.These data should be entered in to an Excel (or equivalent) spreadsheet for subsequent analysis.Within the file, I suggest forming a separate worksheet for each core.
