Demarcation is a factor of vital importance which usually goes unnoticed or is undervalued in this discipline. It limits the study area based on the results obtained in the research.
On the basis of one of the fundamental laws of the Forensic Sciences, any remain found in the area and that has or could has have direct or indirect relation with what we are looking for, no matter if it is necropolis or grave, this evidence could and must be considered part of the site, because it can contribute data which, if it is misread or misinterpreted where it has been found, it could be lost forever.
This way it can give us data from the site’s entrance point of the single tomb to the real extension of a necropolis, showing us the relationship that it has with the landscape around. That gives us a real and complete vision.
