An unmodiefied beach cobble of metabasic igneous cornish "greenstone" utilised as a hammerstone, probably of prehistoric date, c. 8,000 BC - AD 43. The cobble is broady sub-trapezoidal in plan, oval in cross-section and piriform in profile, with the cobble being truncated by extensive, fairly localised battering damage on one end, now worn.

Dimensions: length 85.4mm; width 67.5mm; thickness 51.8mm; weight: >300g.

A similar hammerstone recorded on this database, CORN-2E4F62, references an unmodified "greenstone" hammerstone excavated within a Middle Bronze Age round house at Scarcewater, Penzance (Jones and Taylor 2010: 122, fig. 60, no. 226). However they would have been in use throughout the Prehistoric period, and potentially beyond, and thus cannot be securely dated outside of an archaeolgical context.
