Flint tools have been discovered near Biggar, South Lanarkshire, Scotland. They are very similar to the ones used in the Netherlands and Northern Germany c. 14-12,000 years ago, in the Magdalenian period. This suggests that their users could have originated in that area and crossed through what is now the North Sea, then above sea level (Doggerland).
If the datation could be confirmed, it would mean pushing back the earliest known inhabitation of Scotland by humans more than 3000 years. Before this finding the oldest known human settlements in the country were dated to c. 8500 BP, in the Epipaleolithic period.
