Extensive radiocarbon dating at several sealed sites in North-West Belgium has enabled investigation of the formation processes of spatial and cumulative palimpsests dating to different stages of the Mesolithic. A clear spatio-temporal difference could be observed in the occupation of large versus small sand dunes. The former are characterized by continuous occupation on a seasonal basis over many hundreds of years, mainly during the Early and Final Mesolithic, leading to either extensive spatial palimpsests (Early Mesolithic) or dense cumulative palimpsests (Final Mesolithic). The occupation of smaller sand dunes on the other hand seems more discontinuous but covering the entire Mesolithic and even the Early Neolithic. Furthermore a difference in the relative duration of each occupation stay is likely, with relatively longer stays on larger dunes and more ephemeral visits on smaller dunes.
