The ongoing rescue excavations at the site of Verrebroek - Aven Ackers (East Flanders, Belgium) have revealed a rather small sand dune that has nevertheless indications for a long period of occupation from the Early Mesolithic period onwards to the Neolithic. The site lies in the cover sand area of the so-called " Scheldepolders " and was completely covered with peat and alluvial clay. Although the podzol soil was well preserved, the site was partially disturbed by some late medieval drainage ditches and several wind throw features. At least three occupation areas could be distinguished, of which the largest one is clearly a palimpsest. It contains flint artefacts dominantly dating back to the Middle Mesolithic period but with a clear Early Mesolithic and a Neolithic component. A second, smaller zone probably dates to the Early or Middle Mesolithic. The finds in the third zone indicate a Late Mesolithic occupation. Other than flint artefacts, some heavily abraded ceramics, numerous burnt hazelnut shells and bone fragments were gathered.
