These anthropogenic remains include 72 pieces of leather (including a 650-year-old bit of sheep leather with red lines drawn on it in ochre), 129 bits of cloth and a crossbow bolt with a wooden lance. The team also found 25 items made from esparto grass, including the complete sandal, a slingshot, ropes, fragments of baskets and horse equipment. The team used radiocarbon dating techniques to estimate the ages of the human-made objects, which ranged from between 150 to 675 years old.
