Patrickholme bone bead
|Discovered||Patrickholme, Lanarkshire, Scotland by J. H. Maxwell|
It was found during archaeological excavations in Patrickholme sand quarry in Lanarkshire, Scotland by J. H. Maxwell in 1949. It has been tentatively suggested that this might be tangible evidence of a prehistoric unit of measurement. It measures 33mm and is suggested to date to the Bronze Age. Due to oxidization its original length is uncertain. Three and a half beads were found in total with five other bones that may have been beads. The Patrickholme bone bead was the only one showing a square section that was likely to have been artificially shaped.
