219 Cornish Archaeology 54, 2015, 219–223 An incised Mesolithic pebble from Trevose Head, St Merryn, Cornwall ANDY M JONES In 2010 an incised pebble was discovered amongst the archived fint assemblage from Trevose Head. The fint scatter, which was published in Cornish Archaeology in 1982, is of Mesolithic date and the fnd represents a signifcant addition to the small number of incised pebbles dating to this period in Cornwall. This note provides a description of the fnd and a brief outline of its background and context. In 2010 Emmett O’Keefe, a PhD researcher from University College Dublin, was undertaking analysis of the Mesolithic fint assemblage from Trevose Head as part of his doctoral thesis. During this work he found an elongated pebble which had not been described in the publication of the site (Johnson and David 1982). Closer inspection revealed that a series of shallow parallel lines ran down one side of the stone. Emmett reported the fnd to the author and it was sent to Laura Ratcliffe at the Royal Cornwall Museum who took a series of images at high magnifcation. These images confrmed that the stone had indeed been incised along one side. This short note provides a brief background to the discovery of the incised pebble, a description of the artefact and a concise review of the comparanda for it in Cornwall. Background Trevose Head is located on the north Cornwall coast in the parish of St Merryn. Many fint scatters are located along the stretch of coast between Harlyn Bay to the east and Constantine Island to the west of Trevose (Norman 1977; Wymer 1977, 43–4; Johnson and David 1982). However, most of these scatters are of mixed period (Berridge and Roberts 1986) and the only one that has seen systematic recording is the site known as TV1 (SW 8535 7582) which lies in a feld to the south of the headland (Johnson and David 1982). Fieldwalking over this site led to the recovery of over 8000 fints, the majority being derived from beach pebble material. These were scattered over an area of approximately 60m by 100m, although there were marked concentrations within this overall area. The assemblage included microliths, cores and scrapers, as well as a mass of waste material. The scatter was interpreted as being of mostly later Mesolithic date, although an earlier element was also recognised (Johnson and David 1982). In addition to the fints, a small number of bevelled and elongated pebbles were also illustrated (ibid, fg 7). The incised pebble which forms the focus of this report was not illustrated or described at that time. A description of the pebble It is an elongated ‘pebble’ of metamorphosed siltstone which has not changed completely into a quartzite, measuring 98mm × 23mm × 20mm (Carl Thorpe, pers comm.). It was recovered from grid square 495/500. Some damage has occurred to the surface and end of the pebble; the lower
