NS24SW 9 2313 4218. (Approximately NS 2313 4218) A shell-mound, measuring 102ft by 16ft, on the SW side of Cannon Hill, close to Ardrossan railway station, was excavated by Smith. Its length was mostly overhung by a few feet, by the rock face, which had formed a rock-shelter, which the excavation showed had been occupied at intervals over a considerable period of time. Prior to Smith's excavation, the railway workings had cut a longitudinal section in the mound, which overlay a 1ft layer of raised beach sand. The mound was composed of shells, mainly periwinkle and limpet, and animal bones. Relics found included a stone 'anchor' with a groove cut round it for a rope, a possible stone sinker, fragments of very coarse, hand-made pottery, also some pieces of wheel-turned, glazed pottery, a bone chisel, two bone needles, etc. Human bones, some of which were exhibited in Glasgow in 1911, on loan from Smith, were also found. J Smith 1894; 1895; Palace of History 1911 Bone implements and a hammerstone from this site were donated to the NMAS from the collection of the late J Smith in 1931 (Acc. nos. HR 840-6). Proc Soc Antiq Scot 1931; NMAS Card Index No trace of any remains of this shell mound was seen. Visited by OS (JLD) 7 September 1956
