EEN BIFACE PARTIEL IN DE COLLECTIE VERMANING VAN HET DRENTS MUSEUM

Samenvatting

The Drents Museum of Assen houses a col­lection o f twelve authentic Middle Palaeoli­thic artefacts supplied by the late Tjerk Vermaning, comprising three handaxes, a disque, a Levallois point, a Levallois core, another core, and five flakes. Two hand­axes have already been described (Stapert, 1985). This paper deals with the third handaxe. The piece can be classified as a biface partiel, with the outline of a cordi­forme allongé. The tool was manufactured out of a natural flake-like nodule from the bouldersand. The artefact displays a range of postdepositional surface modifications, such as windgloss, white and brown patinas, and retouches, scratches and pressure cones as a result of cryoturbation. These weathe­ring phenomena most probably date from the Upper Pleniglacial of the Weichselian.
