A site beside the river Tjonger near Jardinga in the northern Netherlands is shown to be a rare Late Mesolithic kill and primary butchering site. Finds consist mainly of bones from aurochs and red deer, with a few flint artefacts. Radiocarbon evidence shows that there must have been two phases of use: the first around 5400 cal BC; the second, main phase around 5250–5050 cal BC.
