Bourville site (chewers), which seems to be located in the region where both cultures first got into contact sometimes around 7100, is of rather short duration, indicating potentially (hostile) destruction of the settlement
Fast demise of chewer’s Talona colony around 7060 corrobates the hypothesis of hostilities
Some years later – around 7000 - the same holds for oriental (Montnesse) and youresian (Mulid) poppy farms
since arrival of farmers in non-Frican regions, no presence of longer-lasting (>1 carbon dated sample period) skinner settlement is observed
