Human remains at the Hardinxveld base camp sites, preserved in different states and under different taphonomic conditions, provide new information on a fairly wide spectrum of mortuary practices in the Late Mesolithic, comprising formal burial, exposure and a form of intentional deposition. The continuation of this same spectrum into the subsequent Neolithic is of help in the interpretation of, in particular, human remains found scattered across sites. This new information we owe to the specific Holocene sedimentary conditions at sites that were silted over shortly after their long-term use. The aforementioned practices may very well be representative of large tracts of the Mesolithic landscape, where information on mortuary rituals is scarce or even altogether absent.
