A
microburin is the residual product of the creation of a
microlith during
flint tool manufacture in many different cultures, for instance the
European Mesolithic. The process, named "microburin blow", involves notching a flint
blade and snapping it in two. The shorter portion is termed the microburin and unlike the microlith it had no functional purpose.
Examples found in Europe can be seen on this page&_160; http://www.archeobase.be/page_microburins_meso.html. They are related with Mesolithic hunters of Walloon region (Belgium) ap. 9 000 years ago.
