The label "in situ" indicates only that the object has not been "newly" moved. Thus, an archaeological "in situ" find may be an object that was historically looted from another place, an item of "booty" of a past war, a traded item, or otherwise of foreign origin. Consequently, the "in situ" find site may still not reveal its provenance, but with further detective work may help uncover links that otherwise would remain unknown. It is also possible for archaeological layers to be reworked on purpose or by accident (by humans, natural forces or animals). For example, in a Tell mound, where layers are not typically uniform or horizontal, or in land cleared or tilled for farming.
