Despite a strong increase in the research on hominin percussive tool use, the primary focus in the study of technological behaviour still lies on flaked stone artefacts, especially for the Middle Palaeolithic. This paper aims to contribute to a more thorough understanding of the full spectrum of homi;nin technological behaviour, by presenting a systematic analysis of ground stone tools from the Last Interglacial Middle Palaeolithic site Neumark-Nord 2/2 (NN2/2) (Germany). At NN2/2, coarse gravel-and cobblesized pieces (n = 351) were sourced from local outcrops of glacial deposits, with a preferential selection for quartzite and sandstone. Low-power use wear analysis and the archaeological context of these finds provide evidence for the possible use of at least 58 pieces for active (hammerstones) and 5 for passive (anvils) percussive tasks, specifically lithic production and potentially bone processing. These grounds stone tools are larger and heavier than the manuports. The hammerstones were preferentially made of quartz and quartzite, while the anvils are mostly of limestone. The limited build-up of use wear on the tools is interpreted as expedient use. The presence of post-depositional J Paleo Arch (2018)
