Burnt hazelnuts and oak charcoal have also been found at BC 5. Like the wood, these types of organic material do not normally survive well in dry, land based, environments. A pit dug into the clay at BC 5 had been filled with burnt clay nodules, charcoal and burnt stones, which had been covered with a large piece of wood. Examining the pit walls revealed that the pit had probably been filled with hot stones on several occasions. Other trenches have revealed chipped wood flakes, flint knapping flakes and even wound fibres that appear to have been used as string. Many of the finds suggest evidence of small scale industry as well as settlement.
