@Setanta,
ANY remains found should be lleft undisturbed because more than half the site forensics is in the surrounds of where the bones were and how they got there.
What if you died and weren't found till many years later and some person just decided to go on a "make believe archeological dig"?
If this were in US, there are several fed and state llaws governing such discoveries.
You should hve some respect and also be concerned about your own health with such things as toxins and long lived phage virus,or bacterial and rickettsial diseases that can be retained in skeletal remains. (Suppose its someone who died from the Spanish flu and you are of a target age, you could develop a sickness and be killed by your own immune system). Or , what if its ebola or some other recent import?
If the soil is acidic and the bones are in fairly good condition, they are probably relatively recent and someone skilled in forensics should do fluorine uptake testing with Xray fluorescence to look at the matrix and the possible age dating (for recent bones only), then a careful exam of the bones is in order by someone whose got the training and experience in dentistry and osteo/ anthropology .
If the bones are initially seen to be older than Flourine dating is valid (about 150 years in acid soils) (and that takes some expert forensics), then other dating techniques would be done but ONLY if the bones aren't moved about and the matrix/soil/bone are preserved in -situ. So if it IS WWII stuff, its a historical site that should be investigated and reburial can occur with dignity and honor to the deceased.
I wouldn't **** with this because you don't sound like youre trained (also, because you've posted this, you cant claim plausible deniability-you've already tipped off anyone that youre "planning" to screw with an antiquity, a missing prson, or even crime scene).
If you are under some pressure to get a construction job done on a schedule and don't report the finding, here in the US you could be guilty of a felony by antiquities or even criminalistics laws. But if you do report it, you are protected from any contractual cross claims by "force majeur"
Have a nice day.
