The date of the greater stonehenge cursus

The Greater Cursus-3km long and just north of Stonehenge-had been dated by a red deer antler found in its ditch in the 1940s to 2890-2460 BC. New excavations by the authors found another antler in a much tighter context, and dating a millennium earlier. It appears that the colossal cursus had already marked out the landscape before Stonehenge was erected. At that time or soon after, its lines were re-emphasised, perhaps with a row of posts in pits. So grows the subtlety of the discourse of monuments in this world heritage site.
