Late Mesolithic Microliths from Budel, a small village in the Dutch province of North Brabant. The raw material is flint and a very fine grained Quartzite (most probably Wommersom Quartzite, from a raw material procurement area 80 km away).
With the beginning of the Late Mesolithic a notable intensification in intergroup communication can be attested for most regions of Europe (Gronenborn, 1997). On the other hand the number of archaeologically visible sites decreases. It is suggested, that this observation probably reflects a change in settlement pattern. This could have been triggered by an increasing density of forests which also resulted in a decrease biomass production. Overall, population numbers seem to have decreased (Zimmermann, 1995) and the Late Mesolithic is seen as a time of crisis, with increasing conflict among neighboring groups.
Stone technology during the late Mesolithic in wide parts of Europe is based on extremely regular blades made by pressure flaking. In the late Mesolithic the regional differences of earlier Mesolithic times seem to have disappeared, although there remains some variability in stylistic details and raw material use (Wommersom Quartzite between the Rheine and Meuse).
The late Mesolithic in the Low Lands is typological quite homogenous. Trapezes, both broad and narrow dominate the micro points. Trapezes seem to appear first in the Mediterranean. In the North their appearance is somewhat later. In the Low countries Trapezes are present around 6500 cal. BC. Further in the North, they are dated about 6200 cal. BC.
