The Lavant drum is small cylindrical Neolithic chalk object excavated in 1993.
[3] The drum was associated with a sherd of Mortlake ware, which implies a Middle Neolithic date.
[4] Anne Teather, Andrew Chamberlain and Mike Parker Pearson proposed in 2019 that the Folkton and Lavant drums were tools to measure cord to standard lengths which were used in the construction of monuments such as Stonehenge and the timber circle at Durrington Walls.
Chamberlain and Parker Pearson propose that the Neolithic long foot is equivalent to 1.056 modern feet or 0.3219 metres.
[8] The drum was discovered in 1993 as part of the excavation of Chalk Pit Lane, Lavant, West Sussex.
