These tiny borers, displayed together with a bladelet and a thumbnail scraper, are surface findings from a linear pottery surface scatter at Kleinerdlingen. Note that the third borer is made from the flint of the Abensberg-Arnhofen flint mine near Regensburg, the largest flint mine in Germany known so far, used mainly during the early and middle Neolithic (5,5-4,5 k.a BC). Recently Arnhofen flint was also descibed for the late Neolithic “Mondsee” culture in Austria.
Kleinerdlingen is situated at the margin of the famous Nördlinger Ries in S/W-Germany. The Ries is a 24-km-diameter depression which is interpreted as a meteorite impact crater, that occurred at 15 Ma. The crater was later covered with loess sediments, especially at the end of the Pleistocene. These fertile sediments were one precondition for LBK farmers to settle down.
