Analysis by dendrochronology was undertaken on samples from two timbers found during archaeological excavation at the site of a former watermill at Toton in Nottinghamshire. This analysis produced dates for both samples. It is estimated that the earlier timber was felled at some point between 1210 at the earliest and 1235 at the latest, while the later timber was felled at some point between 1231 at the earliest and 1256 at the latest. It is possible that these timbers relate to the water mill referred to in the early-fourteenth century documentary evidence.
